Why are Optima batteries preferred in military applications?

Optima batteries dominate military use due to their shock resistance and leak-proof construction. The U.S. Army’s M1A2 Abrams tanks rely on them for 9000+ hours of vibration endurance, outperforming standard batteries failing at 300 hours.

Military equipment operates in extreme terrains where vibration-induced failures can be catastrophic. Optima’s spiral-cell design tightly binds lead plates with AGM separators, eliminating plate shedding – the primary failure mode in conventional batteries. For instance, their sealed casing withstands 180-degree inversion without acid leakage, crucial for armored vehicles navigating steep inclines. Pro Tip: When retrofitting military vehicles, prioritize yellow-top models for deep-cycle capabilities to handle communication systems’ sustained power draws. Transitionally, beyond combat use, this durability extends to aerospace applications – AH-64 Apache helicopters use them for avionics backup power.

How do Optima batteries enhance automotive performance?

Car enthusiasts use Optima batteries for high-cranking power and vibration resistance. Red-top models provide 800+ CCA, ensuring reliable starts in modified engines with high-compression ratios.

In performance vehicles, traditional batteries often fail under hood temperatures exceeding 70°C. Optima’s AGM technology maintains stable voltage output up to 93°C, critical for turbocharged engines. A 2019 study showed modified Mustangs using red-top batteries achieved 0.2-second faster ignition times compared to flooded batteries. Transitionally, their sealed design prevents acid spills during track-day rollovers. But what happens if you install a marine battery in a car? While possible, blue-top models lack the optimized charge acceptance for frequent engine starts. For example, drag racers pair 34R red-top batteries with lightweight lithium setups to balance cranking power and weight savings.

What makes Optima ideal for marine environments?

Optima blue-top batteries excel in marine use through dual-purpose design and corrosion resistance. Their 135-minute reserve capacity outperforms standard marine batteries by 40% in saltwater conditions.

Saltwater accelerates battery terminal corrosion – a major issue for boaters. Optima’s patented Terminox terminals combine lead-tin-copper alloys to reduce corrosion by 70%. During testing, blue-top batteries submerged in 3% saline solution for 48 hours showed no capacity loss, unlike flooded batteries losing 15% capacity. Practically speaking, anglers benefit from their deep-cycle capability – a 31M model can power fishfinders and trolling motors for 8+ hours. Transitionally, what if you need to power a marine stereo system? The D31M variant offers 900 MCA (marine cranking amps) to handle both engine starts and accessory loads simultaneously.

FAQs

Winterizing boat batteries involves disconnecting terminals, cleaning corrosion, and storing at 50-80% charge in a dry, temperature-controlled environment (10-20°C). For lead-acid batteries, maintain 12.4-12.7V; lithium-ion variants (LiFePO4) tolerate 30-50% charge. Use smart chargers monthly to prevent sulfation. Always top-up flooded batteries with distilled water before storage.

What Are the Best Models of LiFePO4 RV Batteries Available in 2024?

Why disconnect battery terminals before winter storage?

Terminal disconnection prevents parasitic drain from onboard electronics, reducing self-discharge rates and corrosion risks. Lead posts corrode 3x faster when exposed to moisture and stray currents—common in marine environments.

Beyond basic cleaning, corrosion creates resistance spikes—imagine a garden hose partially blocked by debris. A 0.5Ω buildup on terminals can slash starting power by 40% in cold weather. Pro Tip: Apply dielectric grease after cleaning terminals with baking soda paste. For example, a Yamaha 115hp outboard left connected over winter may drain its Group 24 battery below recovery voltage. Store disconnected terminals in separate zip-lock bags to avoid accidental contact.

What’s the ideal storage environment for boat batteries?

Batteries last longest in stable 10-20°C environments with 40-60% humidity. Avoid garages with temperature swings—lithium cells degrade 2x faster at 35°C vs. 20°C. Lead-acid suffers plate sulfation below 0°C.

Practically speaking, indoor climate-controlled spaces beat outdoor sheds. A LiFePO4 battery stored in a 15°C basement retains 99% capacity after 6 months, versus 92% in an unheated garage. Use wooden pallets to elevate batteries from concrete floors—they’ll self-discharge 1-2% faster otherwise. Pro Tip: Install a battery monitor like Victron BMV-712 to track voltage remotely. But what if you lack climate control? Insulate batteries with closed-cell foam wraps, maintaining airflow gaps to prevent condensation.

How often should stored batteries be recharged?

Lead-acid requires monthly top-ups; lithium-ion needs bi-monthly checks. Letting AGM batteries drop below 12.2V risks permanent sulfation. Lithium tolerates 3-6 months between charges.

A Trojan T-105 flooded battery self-discharges ~5% monthly at 20°C. Recharge when voltage hits 12.4V (50% SoC). For lithium, partial charges are better—unlike lead-acid, they don’t need full cycles. Pro Tip: Set smart chargers to “storage mode”—Deka’s IntelliCharge maintains 13.2V pulses to prevent stratification. Imagine your battery as a hibernating bear: occasional “snacks” keep it healthy without full activity.

Can you store different battery types together?

Never mix lead-acid and lithium-ion batteries in shared spaces. Lithium’s lower self-discharge masks lead-acid failure risks, and charging vapors from flooded cells corrode lithium terminals.

Case in point: Storing a Battle Born LiFePO4 next to a vented marine battery creates acidic aerosols that degrade BMS components. Separate them by at least 3 meters. Pro Tip: Label batteries with chemistry and voltage—a Sharpie on masking tape works. If space is tight, use sealed plastic bins with silica gel packs. But why risk it? Dedicate separate shelves for different chemistries.

What maintenance is needed during storage?

Monthly voltage checks and terminal cleaning are essential. For flooded batteries, check electrolyte levels every 60 days—distilled water only. Use hydrometers to test specific gravity (>1.225).

Consider this: A neglected Group 31 battery loses 0.1V/month, crossing into sulfation territory by week 10. Pro Tip: Photograph battery labels and wiring before disconnecting—it prevents spring reconnection errors. Example: A dual-bank setup with switchable paralleling requires careful documentation. Ever wonder why marinas charge $150 for winterization? Half the cost covers battery maintenance labor.

How to revive batteries after winter storage?

Recharge slowly (10% C-rate) and check for voltage recovery. Lead-acid below 10.5V may need desulfation cycles. Lithium batteries under 2.5V/cell require professional recovery.

For instance, a fully discharged AGM battery taking 12+ hours to reach 12.7V likely has damaged plates. Pro Tip: Use load testers—a 50% voltage drop under 15-second 100A load indicates replacement time. Think of post-storage testing like a medical check-up: catching issues early prevents system-wide failures. Ever seen a swollen battery case? That’s your cue for immediate replacement—no exceptions.

Pro Tip: Pair batteries with a compatible inverter (e.g., 2,000W for 200Ah systems) to avoid overloads.

What Are the Best Models of LiFePO4 RV Batteries Available in 2024?

What battery chemistry works best for RVs?

LiFePO4 batteries dominate for RVs due to 80% depth of discharge and lightweight designs. AGM offers maintenance-free operation, while flooded lead-acid is cheaper but requires ventilation.

RV batteries must balance cycle life, weight, and upfront costs. LiFePO4 cells deliver 3,000+ cycles at 80% DoD, outperforming AGM (500 cycles) and flooded (300 cycles). For example, a 100Ah LiFePO4 battery weighs ~30 lbs, while AGM equivalents exceed 60 lbs. Pro Tip: Use a battery monitor to track DoD—discharging lead-acid beyond 50% drastically shortens lifespan. However, why choose lithium if you’re on a tight budget? Initial costs are higher, but long-term savings offset this. Transitional note: Beyond chemistry, sizing matters just as much.

How do I calculate the right battery capacity?

Estimate daily watt-hour consumption (appliances x runtime) and divide by battery voltage. Add 20% buffer for inefficiencies.

Start by listing all RV appliances: a 150W fridge running 24 hours consumes 3,600Wh. Add lighting (200W), microwave (1,000W x 0.5h), and outlets (500Wh). Total ~5,300Wh daily. A 12V system needs 5,300Wh / 12V = 442Ah, requiring a 500Ah LiFePO4 bank. Pro Tip: Use a 200Ah battery for minimal usage (lights + phone charging). But what if you’re boondocking? Double capacity for cloudy days. Real-world example: Two 200Ah LiFePO4 batteries provide 4,800Wh, sufficient for 2 days without charging. Transitional note: Sizing also depends on charging methods.

Are maintenance-free batteries worth it?

AGM and LiFePO4 are maintenance-free, ideal for RVs. Flooded batteries need monthly watering but cost 50% less.

AGM batteries seal electrolytes, preventing leaks and allowing tilt installation. Lithium batteries eliminate terminal corrosion, whereas flooded types require distilled water refills and vented compartments. For example, a flooded battery bank in a camper might need biweekly checks—a hassle during winter. Pro Tip: Opt for AGM if upgrading from flooded without changing charging systems. Still, how critical is maintenance time? For frequent travelers, lithium’s zero upkeep saves hours annually.

How does temperature affect RV batteries?

Lithium batteries operate in -4°F to 140°F but lose 20% capacity in freezing temps. Lead-acid performs worse below 32°F.

Battery chemistry dictates cold-weather resilience. LiFePO4 includes built-in heaters for sub-freezing charging, while AGM struggles below 20% efficiency at 0°F. For instance, winter campers in Colorado should preheat lithium packs via solar or shore power. Pro Tip: Insulate battery compartments with foam sleeves. But what about extreme heat? Above 100°F, lead-acid loses 50% lifespan, whereas lithium handles heat better. Transitional note: Temperature impacts parallel charging setups.

Can solar panels charge RV batteries effectively?

Yes, with MPPT charge controllers optimizing solar input. LiFePO4 charges 2x faster than lead-acid under partial sun.

400W solar panels can generate ~1,600Wh daily—enough for a 200Ah LiFePO4 battery. MPPT controllers boost efficiency by 30% compared to PWM. For example, a cloudy day might yield 25% output, still adding 20Ah to the bank. Pro Tip: Angle panels at 45° in winter for maximum exposure. But how stable is solar-only charging? Pair with a DC-DC charger from the alternator for redundancy.

FAQs

Proper RV battery care requires regular voltage checks, terminal cleaning, and balanced charging. AGM and LiFePO4 batteries demand specific maintenance—monitor electrolyte levels (flooded types) or use temperature-compensated chargers (lithium). Store at 50-80% charge in cool, dry spaces to prevent sulfation or thermal runaway. Always wear PPE during inspections, and avoid overdischarging below 12V for lead-acid or 10% SOC for lithium systems.

Understanding Battery Reserve Capacity Explained

Why is regular inspection crucial for RV batteries?

Monthly inspections prevent corrosion buildup and internal shorts. Check terminals for green/white oxidation, verify electrolyte levels in flooded batteries, and test voltage stability. Unaddressed wear reduces capacity by 15% annually. Pro Tip: Apply dielectric grease post-cleaning to deter future corrosion.

Failing to inspect batteries risks acid leaks and fire hazards. Start by measuring resting voltage: 12.6V+ indicates healthy lead-acid, while LiFePO4 should sit above 13V. Physically inspect casing for cracks—even hairline fractures let moisture in, accelerating discharge. Did you know a single corroded terminal can spike resistance by 200%? Use a baking soda/water mix (1:10 ratio) to neutralize acid residue. For lithium packs, check BMS connections and cell balance monthly. Example: A Class A RV owner caught a swollen LiFePO4 cell early, preventing thermal runaway. Transitional Tip: Pair inspections with tire pressure checks to build a routine.

How do you safely charge RV batteries?

Use smart chargers matching battery chemistry. Lead-acid needs 14.4-14.8V absorption; LiFePO4 charges at 14.6V max. Never exceed 25% of bank capacity in charging amps. Pro Tip: Install a shunt monitor to track SOC accurately.

Charging errors cause 63% of RV battery failures. Lead-acid requires bulk/absorption/float stages, while lithium uses CC-CV. But what happens if you use a lead-acid charger on LiFePO4? Overvoltage triggers BMS shutdowns, risking cell imbalance. Temperature matters—charge lead-acid above 0°C, lithium above -10°C. Example: A travel trailer’s AGM bank failed after using a lithium charger’s higher voltage. Transitional Advice: Integrate solar controllers with temp sensors for adaptive charging. Table below compares charging parameters:

What are optimal storage practices for RV batteries?

Store at 50-80% SOC in 10-25°C environments. Disconnect negative terminals and use battery maintainers for lead-acid. Lithium self-discharges 2% monthly; recharge every 3 months. Pro Tip: Elevate batteries off concrete to reduce temperature swings.

Improper storage accelerates degradation. Lead-acid loses 1-2% charge daily; a 50% SOC prevents sulfation. For lithium, partial charge reduces electrolyte stress. Example: Storing a Trojan T-105 at 100% SOC degraded capacity 40% faster. Use climate-controlled spaces—garages exceeding 35°C double lead-acid water loss. Transitional Note: Combine storage prep with RV tire covers for comprehensive offseason care. Table:

What Makes Duracell Marine Batteries a Top Choice for Boaters?

The 24DC-XHD Marine RV Battery is a 24-volt extra heavy-duty battery designed for marine and recreational vehicle applications. It typically combines LiFePO4 chemistry with capacities ranging from 100Ah to 200Ah, providing robust cycle life (3,000–5,000 cycles) and deep discharge capabilities (80%–100% DoD). Optimized for solar compatibility and vibration resistance, these batteries power trolling motors, onboard electronics, and off-grid RV systems while maintaining safety through integrated BMS protection.

What Are the Best Models of LiFePO4 RV Batteries Available in 2024?

What voltage defines a 24DC-XHD battery system?

The 24DC-XHD operates at a nominal 24V, making it suitable for high-power marine thrusters and RV air conditioners. Pro Tip: Voltage consistency within ±1% prevents inverter tripping during heavy loads.

This system’s 24V architecture reduces current draw by 50% compared to 12V batteries when delivering equivalent power, minimizing heat buildup in wiring. For example, a 24V 200Ah battery running a 2kW RV AC unit sustains 83A current versus 166A at 12V. Mechanical stress on connectors and terminals decreases proportionally. However, users must ensure all connected devices (e.g., solar charge controllers) support 24V input. Practical analogy: Think of voltage as water pressure—higher voltage pushes energy more efficiently through systems without requiring thicker “pipes” (cables).

Why choose LiFePO4 chemistry for marine/RV use?

LiFePO4 offers thermal stability and 4x the cycle life of lead-acid, critical for saltwater environments.

Marine conditions demand batteries resistant to corrosion and thermal runaway—LiFePO4’s stable cathode structure withstands temperatures up to 60°C (140°F) without off-gassing. Unlike AGM batteries that degrade below 50% DoD, LiFePO4 handles 80–100% daily discharge. For example, a 24V 200Ah LiFePO4 pack can power a marine refrigerator (150W) for 32+ hours versus 18 hours with AGM. Pro Tip: Use compression plates during installation—LiFePO4 cells last 30% longer when moderately clamped to prevent delamination from wave impacts.

How do charging protocols differ for 24V systems?

24V LiFePO4 requires 28.8V absorption voltage with temperature-compensated charging.

Chargers must follow CC-CV (Constant Current-Constant Voltage) profiles tailored to LiFePO4’s flat voltage curve. A quality marine charger delivers 30A–60A bulk charge until reaching 28.8V, then maintains 27.6V float. Solar setups need MPPT controllers rated for 24V—budget PWM types waste 15–30% efficiency. Real-world example: A 400W solar array charges a 24V 200Ah battery from 20% to full in 5.2 sun hours (400W ÷ 28.8V ≈ 13.9A; 160Ah needed ÷ 13.9A ≈ 11.5 hours). But what if partial shading occurs? Parallel charging with alternators helps—dual 40A DC-DC chargers add 80A replenishment while sailing.

What capacity (Ah) suits marine/RV needs?

200Ah is the sweet spot for most 24V systems, balancing runtime and weight.

Boats requiring trolling motors (e.g., 80lb thrust Minn Kota draws 50A at full throttle) need 200Ah+ to sustain 4+ hours of continuous use. RVs with 2kW inverters should size batteries using this formula: (Total Wh/day ÷ 24V) × 1.2 = Minimum Ah. Example: Daily usage of 5kWh (5,000Wh) requires (5,000 ÷ 24) × 1.2 ≈ 250Ah—so two 24V 125Ah batteries in parallel. Pro Tip: Reserve 20% capacity for emergency starts—marine engines sometimes need brief 500A cranking bursts.

Are safety certifications mandatory?

ABS, USCG, and UN38.3 certifications are non-negotiable for marine lithium batteries.

Boats in US waters require USCG-certified batteries meeting ABYC TE-13 standards for flame arrestors and pressure relief. LiFePO4 packs must pass UN38.3 tests simulating vibrations (7Hz–200Hz for 3 hours) and thermal shock (-40°C to +75°C). Redway’s 24DC-XHD models exceed these with IP67 waterproofing and cell-level fuses—crucial when waves splash battery compartments. Imagine a certified battery as a life vest: It won’t prevent storms but dramatically improves survival odds during electrical faults.

Can I retrofit 24V into a 12V vehicle?

Retrofitting demands controller/motor upgrades—24V doubles RPM in unmodified 12V motors.

Rewinding motors for 24V or installing voltage-doubling alternators avoids burnout. For RVs, replace 12V LED lights (9–36V models exist) and install a 24V-to-12V converter (30A–60A) for legacy devices. Case study: Converting a Winnebago’s 12V system to 24V cut wiring costs 40% by halving required copper. But why risk DIY? Professional retrofitters laser-weld connections to handle 24V’s higher arc potential—critical in fuel-rich marine engine bays.

Core electrochemical systems include lithium-ion variants (NMC, LFP), lead-acid batteries (AGM, Gel), and nickel-based cells. Sodium-ion and solid-state designs are gaining traction for sustainable energy storage, while supercapacitors support rapid charge/discharge cycles. Pro Tip: Lithium iron phosphate (LFP) now dominates EV applications due to superior thermal stability versus traditional NMC chemistries.

Modern battery technologies are evolving across three dimensions: energy density improvements, cost reduction through material innovation, and safety enhancements. For electric vehicles, pouch cells using NMC811 cathodes achieve 280Wh/kg, while prismatic LFP cells offer 2,000+ cycles at 80% DoD. Industrial applications still rely on flooded lead-acid batteries for UPS systems due to their 8-10 year lifespans in standby modes. A real-world example: Tesla Megapack installations use LFP chemistry for grid storage, providing 3MWh capacity per unit with 100% depth of discharge capability. Practically speaking, choosing between chemistries involves trade-offs—while solid-state batteries promise 500Wh/kg densities, current prototypes cost 8x conventional lithium-ion cells.

Portable devices use coin cells (CR2032), cylindrical Li-ion (18650), and polymer packs with capacities from 500mAh to 20,000mAh. Key differentiators include discharge rates (1C for smartphones vs 30C for drone batteries) and charging protocols (Qi wireless vs USB-PD). Warning: Using non-OEM replacement batteries risks thermal runaway—always verify IEC 62133 certification.

Smartphone batteries typically employ stacked lithium-polymer designs with 3.8V nominal voltage and multi-stage protection circuits. Compared to EV batteries, they prioritize volumetric energy density—Apple’s 4,852mAh iPhone 15 Pro Max battery achieves 679Wh/L through silicon-carbon composite anodes. For photographers, Nikon EN-EL15c Li-ion packs provide 14.6Wh capacity with low self-discharge (<10% monthly). Did you know? Premium drone batteries like DJI Intelligent Flight Batteries integrate fuel gauge ICs and cell balancing directly in the pack, enabling 40-minute flight times. However, attempting DIY repairs on swollen LiPo batteries can release toxic electrolytes—professional disposal through certified centers is mandatory.

What defines industrial battery systems?

Industrial-grade batteries emphasize high cycle life and safety certifications, with lead-acid variants still holding 62% market share for backup power. Lithium titanate (LTO) cells excel in cold environments (-40°C operation), while flow batteries provide 20,000+ cycles for renewable integration.

Data center UPS systems commonly use valve-regulated lead-acid (VRLA) batteries in 480V configurations, providing 5-15 minutes of critical load support. For wind farm applications, vanadium redox flow batteries offer 20-year lifespans with 100% daily cycling capacity. A notable case: South Australia’s 150MW/194MWh Hornsdale Power Reserve uses Tesla Powerpacks for frequency regulation, responding to grid demands within 140 milliseconds. Pro Tip: When commissioning industrial batteries, always perform impedance testing—cell resistance over 30% above baseline indicates impending failure. Emerging alternatives like zinc-bromine flow batteries are challenging lithium-ion in long-duration storage, offering 12-hour discharge cycles without degradation.

FAQs

6V AGM marine/RV batteries are Absorbent Glass Mat lead-acid batteries optimized for deep-cycle use in boats and RVs. Their 6V design allows safe series configurations (e.g., two for 12V systems), while AGM technology provides spill-proof operation, vibration resistance, and 3-5x faster recharge than flooded batteries. Typical capacities range 200–250Ah (at 20hr rate) with 500–800 cycles at 50% DoD.

Why choose 6V AGM batteries for marine/RV use?

6V AGM systems excel in deep-cycle reliability and space efficiency. Unlike single 12V batteries, dual 6V units in series offer balanced cell wear and higher total capacity (e.g., 2x6V 225Ah = 12V 225Ah vs. single 12V 100Ah). AGM’s sealed design prevents acid leaks during vessel tilting—critical for marine stability.

Marine/RV applications demand sustained power for trolling motors, winches, or inverters. A 6V AGM battery typically handles 50-80% depth of discharge (DoD) daily without sulfation. Pro Tip: When wiring in series, use identical batteries—mixing capacities or ages creates imbalance. For example, two 6V 230Ah AGM batteries power a 2,000W RV inverter for 4-5 hours. But why not use 12V instead? Thicker plates in 6V models withstand deeper discharges, extending cycle life by 30-40%.

How does AGM technology enhance deep-cycle performance?

AGM (Absorbent Glass Mat) batteries use fiberglass separators saturated with electrolyte, eliminating free liquid. This design enables faster recharge (up to 40% of capacity hourly) and reduces internal resistance. Marine AGM units maintain 12.8V under 50A loads, whereas flooded types drop to 12.3V.

The compressed glass mats minimize active material shedding—a key failure point in deep cycles. Testing shows AGM batteries retain 85% capacity after 600 cycles at 50% DoD vs. 65% for flooded. Practically speaking, this means an RV owner could camp off-grid for 3 years without replacements. Pro Tip: Charge AGMs to 14.4-14.8V (absorption stage) before float—undercharging below 13.8V accelerates sulfation. Imagine AGM mats as sponges: they hold acid tightly, allowing efficient ion transfer even when shaken—perfect for bumpy roads.

What maintenance do 6V AGM batteries require?

AGM batteries are marketed as maintenance-free, but basic care extends lifespan. Key tasks include terminal cleaning (prevents corrosion), torque checks (vibration loosens connections), and voltage monitoring—below 12V risks permanent damage.

Unlike flooded batteries, AGMs don’t need watering but still require annual capacity testing. Use a carbon pile tester: a healthy 6V AGM should maintain ≥5.8V under 300A load for 15 seconds. But what if you’re on a months-long sailing trip? Install a Bluetooth battery monitor—apps like VictronConnect track SoC (State of Charge) in real time. Example: A corroded terminal can increase resistance by 0.05Ω, wasting 20W/hour in a 20A system. Pro Tip: After deep discharges, recharge within 24 hours to prevent sulfation hardening.

6V vs 12V AGM: Which is better for marine/RV?

6V AGM batteries dominate in high-capacity setups, while 12V suits compact needs. Two 6V 225Ah units (wired to 12V) provide 225Ah, whereas a single 12V 100Ah AGM offers half the runtime but 30% less weight.

For house banks powering inverters or lighting, 6V’s thicker plates handle daily 50% discharges better. However, 12V AGMs simplify wiring in small boats—no series connections needed. Practical example: A 30ft sailboat uses eight 6V AGMs (4x12V banks) for 900Ah, while a campervan might use two 12V 200Ah for simplicity. Beyond capacity, consider space—6V batteries are taller but narrower. Transitioning? Always match your alternator’s output—AGMs require 14.4V charging, incompatible with older 13.8V regulators.

What impacts 6V AGM battery lifespan?

Depth of Discharge and temperature are lifespan dictators. Discharging to 80% DoD cuts cycle life by 60% compared to 50%. Heat above 30°C (86°F) increases corrosion—every 8°C rise halves longevity.

Proper charging matters most. Use a three-stage charger (bulk/absorption/float) programmed for AGM—overcharging at 15V+ dries the mats. Imagine electrolyte as water in towels: squeeze too hard (overcharge), and the fibers degrade. Pro Tip: Install temperature sensors on batteries—smart chargers adjust voltage based on readings. A 6V AGM bank in Arizona might last 4 years vs 7 in Maine. Transitional tip: Partial SoC (20-80%) storage slows aging—store at 50% if unused for months.
