Top Picks for Best Lithium Golf Cart Battery

What drives the high cost of lithium golf cart batteries?

Lithium batteries use high-grade lithium, cobalt, and nickel, with LiFePO4 variants demanding strict stoichiometric ratios. Mining and refining these materials account for 40–50% of total costs. Pro Tip: Opt for LiFePO4 if possible—its longer lifespan offsets upfront costs.

Beyond raw materials, manufacturing lithium cells requires dry rooms with <1% humidity and nanoscale electrode coatings to prevent dendrites. For example, a 72V 100Ah LiFePO4 pack involves 224 cells, each laser-welded and tested for impedance consistency. Why does this matter? Even minor defects can trigger BMS shutdowns or reduce capacity by 15–30%. Transitionally, these precision steps limit production speed, keeping per-unit costs high compared to lead-acid alternatives.

Factor	Lithium	Lead-Acid
Material Cost	$90/kWh	$60/kWh
Cycle Life	2,000+	500

How does BMS complexity affect pricing?

Golf cart BMS units monitor cell voltage, temperature, and current with 1–2% accuracy, using MOSFETs and microcontrollers. These systems prevent over-discharge below 2.5V/cell, which can permanently damage lithium packs.

Practically speaking, a 72V BMS manages 20–24 cells, each requiring individual balancing during charging. For instance, Redway’s BMS auto-adjusts currents to maintain ±10mV cell variance—a feature absent in budget lead-acid systems. But what if the BMS fails? Catastrophic thermal runaway becomes a risk, hence the need for redundant sensors and firmware. Transitionally, these safeguards explain why BMS units constitute 15–20% of total battery costs.

⚠️ Critical: Never bypass the BMS—doing so voids warranties and risks fire.

Is It OK To Replace Just One Golf Cart Battery?

Replacing a single golf cart battery is strongly discouraged due to the interconnected nature of battery systems. Golf carts typically use 6V, 8V, or 12V batteries wired in series to achieve 36V, 48V, or 72V systems. Mixing old and new batteries creates imbalances in voltage, capacity, and internal resistance, accelerating degradation of the entire pack. Always replace all batteries simultaneously to ensure uniform performance and longevity.

Top Picks for Best Lithium Golf Cart Battery

Why can’t I replace just one battery?

Voltage mismatch and capacity imbalance are primary concerns. A new battery charges/discharges faster than aged ones, forcing the BMS to compensate erratically. Pro Tip: Test all batteries with a load tester—if voltage drops >0.5V under load, full replacement is urgent.

Golf cart batteries work as a team—imagine runners tied in a three-legged race. One weak member slows everyone. In a 48V system (eight 6V batteries), a single degraded unit reduces total runtime by 25%+ and risks overcharging others. Critical thresholds: Replace if any battery’s specific gravity varies >0.050 between cells or rests below 1.225 after charging.

⚠️ Warning: Partial replacement voids most battery warranties and may damage chargers due to voltage sensing errors.

What happens if I ignore this advice?

Thermal runaway and premature failure become likely. The new battery overworks to compensate for weaker units, generating excess heat. Did you know? A 10°C temperature rise doubles corrosion rates in lead-acid batteries.

Case study: A user replaced one 8V battery in a 48V EZ-GO pack. Within 30 cycles, the new battery’s capacity dropped 40% as it constantly “donated” energy to older cells. Charger errors spiked, mistaking the pack’s uneven voltage for a faulty connection. Transitional note: Beyond individual cell impacts, partial replacements strain the controller, risking MOSFET burnout from inconsistent current flow.

Single Battery Replaced	Full Pack Replacement
~80-150 cycles remaining	800-1,200 cycles (LiFePO4)
High risk of BMS faults	Stable voltage curves

Redway Battery Expert Insight

Always replace golf cart batteries as a complete set. Mixed-age packs develop “lazy cell syndrome,” where older units leach energy from new ones. Our LiFePO4 batteries include matched internal resistance (±2%) and synchronized aging protocols, ensuring balanced performance throughout their 10-year lifespan. For lead-acid systems, full replacement every 4-5 years remains non-negotiable.

FAQs

Can I temporarily replace one battery?

Only for <72 hours in emergencies. Immediately balance the pack by charging at 10% below standard voltage to prevent overstress on the new unit.

Do lithium batteries allow single replacements?

No—even with modular LiFePO4, always swap all cells. Internal resistance matching is factory-calibrated; adding new cells disrupts current distribution.

What Charges The Battery On A E-Z-GO Gas Golf Cart?

The battery in an E-Z-GO gas golf cart is charged by a starter-generator driven by the engine’s crankshaft. This component acts as both a starter motor and an alternator, converting mechanical energy into electrical energy during operation. A voltage regulator maintains output between 13.8V–14.4V to prevent overcharging the 12V lead-acid battery, which powers lights, accessories, and ignition. Pro Tip: Clean battery terminals monthly—corrosion disrupts charging efficiency and accelerates wear.

Top Picks for Best Lithium Golf Cart Battery

How does the starter-generator charge the battery?

A starter-generator combines starting and charging functions. When the engine runs, its pulley spins the generator via a belt, producing AC current rectified to DC to replenish the battery. The voltage regulator caps output to 14.4V, balancing charge rates with electrical loads. Without this system, the battery would drain within 30–60 minutes of accessory use.

Deep Dive: The starter-generator’s dual role simplifies the cart’s design but introduces unique maintenance needs. For instance, a worn drive belt reduces charging efficiency, causing the battery to discharge during uphill climbs. Pro Tip: Test charging voltage with a multimeter—readings below 13.2V under load indicate belt slippage or regulator failure. Think of the starter-generator as a car’s alternator: both recharge batteries but in a compact, single-unit package. A real-world example: E-Z-GO TXT models use a 12V, 25A system; if headlights dim at idle, the regulator may be faulty.

⚠️ Warning: Never bypass the voltage regulator—uncontrolled output can boil battery electrolytes, damaging cells in under an hour.

What role does the voltage regulator play?

The voltage regulator stabilizes the starter-generator’s output, preventing spikes that fry electronics or overcharge the battery. It adjusts field current to maintain 14.4V ±0.2V, critical for lead-acid battery longevity. Without it, voltage could surge to 18V+ during high RPMs, causing permanent damage.

Deep Dive: Modern solid-state regulators outperform older mechanical units by reacting faster to load changes. For example, turning on headlights drops system voltage momentarily, but a good regulator compensates within 0.5 seconds. Pro Tip: If your battery’s water levels drop rapidly, test the regulator—excessive voltage accelerates electrolysis. Consider this component the “traffic cop” of your cart’s electrical system, directing energy flow safely. Interestingly, some upgraded lithium batteries tolerate wider voltage ranges (12V–16V), reducing regulator dependency. But what happens if the regulator fails? You’ll notice flickering lights or a burning smell from overheating wires.

Regulator Type	Response Time	Compatibility
Mechanical	2–5 seconds	Pre-2000 models
Solid-State	0.1–0.5 seconds	2000+ models

Can you charge the battery externally?

Yes, using a 12V automotive charger on the battery terminals. However, E-Z-GO’s charging system typically maintains sufficient charge during regular use. External charging is only needed for long storage periods or if the starter-generator malfunctions.

Deep Dive: When using external chargers, select a 2–10A smart charger with automatic shutoff. Trickle charging at 2A for 6–8 hours rejuvenates deeply discharged batteries without overheating plates. Pro Tip: Disconnect battery cables before charging—some regulators can be damaged by reverse current. Imagine this as giving your cart a “vitamin boost” when its internal systems aren’t enough. For example, carts stored over winter often need a full charge cycle every 60 days to prevent sulfation.

Lead-acid vs. lithium-ion: Charging differences?

Lead-acid batteries require voltage-regulated charging (13.8V–14.4V), while lithium-ion (LiFePO4) need precise 14.6V ±0.2V with BMS protection. Lithium cells charge faster (3–4 hours vs. 6–8) and tolerate partial cycles better, but require upgraded charging systems.

Deep Dive: Swapping to lithium cuts charging time by 50% and doubles cycle life, but demands a compatible charger and often a voltage regulator adjustment. Pro Tip: Check if your starter-generator outputs at least 14.6V before converting—older E-Z-GO models may need a lithium-specific regulator. It’s like upgrading from a garden hose to a pressure washer: more power, but you need the right connectors. A real-world example: Redway’s 12V 100Ah LiFePO4 charges fully in 3 hours at 30A vs. 8 hours for lead-acid.

Parameter	Lead-Acid	Lithium
Charge Voltage	13.8–14.4V	14.4–14.6V
Cycle Life	500	2000+

What maintenance ensures reliable charging?

Monthly terminal cleaning, belt tension checks, and voltage tests preserve charging efficiency. Annual regulator inspections prevent over/under-charging. For lead-acid batteries, maintain electrolyte levels with distilled water every 2–3 months.

Deep Dive: A loose starter-generator belt slips under load, dropping charge rates by up to 70%. Use a belt tension gauge—45–50 lbs of pressure should deflect the belt 0.5 inches. Pro Tip: Apply dielectric grease on terminals after cleaning—it prevents corrosion without hindering conductivity. Think of this routine as your cart’s “dental checkup”: small efforts prevent major breakdowns. For example, a 2018 E-Z-GO Express with proper maintenance can retain 95% charging capacity after 5 years.

⚠️ Critical: Never add tap water to batteries—minerals cause sulfation, reducing capacity by 20–40%.

Redway Battery Expert Insight

E-Z-GO gas carts thrive with robust 12V batteries, but upgrades to LiFePO4 enhance performance. Our lithium batteries integrate BMS protection, handling the starter-generator’s variable output while offering 2000+ cycles. For carts with frequent accessory use, we recommend 100Ah+ capacities paired with auto-balancing regulators—ensuring reliable starts and sustained power for lights, stereos, and GPS systems.

FAQs

Can I use a car battery charger on my E-Z-GO?

Yes, but set it to 12V/2–10A mode. Avoid high-amp “jump start” settings—they can warp lead-acid plates.

How often should I replace the battery?

Every 3–5 years for lead-acid; 8–10 years for lithium. Voltage drops below 10.5V under load signal replacement.

Why does my battery drain overnight?

Parasitic drains from accessories or a faulty voltage regulator are common culprits. Test with a multimeter— >50mA draw indicates a short.

How Many Amp Hour Battery Do You Need For A Golf Cart?

For most golf carts, a battery bank with 150–250Ah total capacity (at 6V or 8V per battery) is standard, though heavy usage or hilly terrain may require 300–400Ah. Typical configurations use 4–8 deep-cycle lead-acid batteries (e.g., Trojan T-105 6V 225Ah) in series to achieve 36V, 48V, or 72V systems. Lithium alternatives like 48V 100Ah LiFePO4 packs provide equivalent runtime at half the weight. Pro Tip: Multiply your cart’s daily mileage by 20–25Wh/km to calculate Ah needs—a 15km/day cart needs ~48V 150Ah.

Top Picks for Best Lithium Golf Cart Battery

What factors determine golf cart battery Ah requirements?

Key factors include cart weight (300–700kg), terrain incline, and daily runtime. A 48V system using six 8V 170Ah batteries delivers ~10kWh, sufficient for 30–40km on flat ground. Hilly courses may require 20% higher capacity. Pro Tip: Voltage impacts torque—higher voltage systems (72V) draw fewer amps for the same power, reducing battery stress.

How do lead-acid and lithium batteries compare for Ah needs?

Lithium batteries provide 95% usable capacity vs. lead-acid’s 50%, meaning a 100Ah LiFePO4 pack equals 200Ah FLA. Though lithium has higher upfront cost, its 2,000+ cycles (vs. 500–800 for lead-acid) reduces long-term Ah degradation. For example, a 48V 100Ah lithium pack typically outlasts 48V 200Ah lead-acid in deep-daily-cycle applications.

Battery Type	Usable Ah	Cycle Life
Flooded Lead-Acid	50%	500–800
LiFePO4	95%	2,000–5,000

What happens if you undersize battery capacity?

Undersizing causes voltage sag during acceleration and reduced lifespan. A 48V cart drawing 100A peaks needs batteries rated for at least 150A continuous discharge. For lead-acid, capacity drops 1% per °C below 25°C—winter runtime may require 30% extra Ah. Pro Tip: Always oversize lead-acid banks by 20% to avoid damaging depth-of-discharge (keep above 50% SoC).

How to calculate Ah for custom golf cart setups?

Use: Ah = (Watts × Hours) ÷ Voltage. A 5kW motor running 2 hours daily on 48V needs (5000W × 2h) ÷ 48V ≈ 208Ah. Add 25% buffer: 260Ah. For lithium, divide by 0.95 (usable capacity): 208 ÷ 0.95 ≈ 219Ah. Real-world example: Club Car’s 48V 158Ah lithium pack supports 50km range at 25km/h.

Motor Power	Runtime	Required Ah (48V)
3kW	3h	187Ah
5kW	2h	208Ah

Why do battery configurations matter for total Ah?

Series connections increase voltage but keep Ah constant, while parallel setups boost Ah at same voltage. Six 8V 170Ah batteries in series make 48V 170Ah. Two parallel strings of six 8V 170Ah create 48V 340Ah. Pro Tip: Never mix old/new batteries—20% capacity variance can cause thermal runaway in lead-acid banks.

⚠️ Critical: Lithium BMS must balance cell voltages—unbalanced packs lose 30–50% effective Ah capacity.

Redway Battery Expert Insight

How Long Do 48 Volt Golf Cart Batteries Last?

48V golf cart batteries typically last 5–8 years with lithium-ion (LiFePO4) variants offering 3,000+ charge cycles, significantly outperforming lead-acid alternatives. Actual lifespan depends on usage patterns, depth of discharge (DoD), and maintenance. For example, a 48V 100Ah LiFePO4 pack discharged to 80% daily retains ~80% capacity after 2,000 cycles. Proper charging practices and temperature control (0–25°C storage) further extend operational life.

Top Picks for Best Lithium Golf Cart Battery

What factors determine 48V battery lifespan?

Key factors include cycle count, depth of discharge, and thermal management. LiFePO4 chemistry handles 80% DoD without accelerated degradation, unlike lead-acid batteries limited to 50% DoD. Pro Tip: Avoid full discharges—keeping batteries above 20% charge reduces stress on cathode materials.

Battery longevity hinges on three technical parameters: cycle life rating (e.g., 3,000 cycles at 80% DoD), charge efficiency (>98% for LiFePO4 vs. 70–85% for lead-acid), and internal resistance. Higher resistance generates heat during high-current draws, accelerating capacity fade. For perspective, a 48V 80Ah pack powering a 500W motor lasts ~1.5 hours at full load but degrades 30% faster if operated above 35°C ambient temperatures. Transitioning to real-world scenarios, golf carts used seasonally in mild climates often outlast year-round tropical deployments. A practical analogy: LiFePO4 batteries are like marathon runners—consistent performance under controlled conditions—while lead-acid models resemble sprinters, delivering short bursts with frequent “recovery” needs.

⚠️ Critical: Never use lead-acid chargers for lithium batteries—voltage mismatch can trigger BMS faults and void warranties.

How do lithium and lead-acid batteries compare?

Lithium batteries provide 3–5x longer service life than lead-acid equivalents. While AGM batteries typically last 2–4 years, LiFePO4 units maintain usable capacity beyond 8 years with proper care.

Beyond basic chemistry differences, lithium batteries exhibit flatter voltage curves, maintaining stable power output until ~10% remaining capacity. Lead-acid systems experience voltage sag beyond 50% discharge, forcing users to oversize banks. Let’s break it down: A 48V 105Ah lithium battery delivers 5.04kWh usable energy (105Ah × 48V × 0.95 efficiency), whereas a 200Ah lead-acid bank provides equivalent usable energy (200Ah × 48V × 0.5 DoD = 4.8kWh) but weighs 2.3x more. Transitional phases in battery aging also differ—lithium cells lose capacity linearly (~2% per year), while lead-acid degrades exponentially after the 18-month mark. Pro Tip: Monitor voltage sag during acceleration; consistent drops below 46V under load indicate battery replacement is due.

Parameter	LiFePO4	Lead-Acid
Cycle Life (80% DoD)	3,000+	500–800

How do I determine my golf cart’s voltage system?

Check existing batteries or the manufacturer’s manual—common systems are 36V (six 6V), 48V (six 8V or four 12V), or 72V. Pro Tip: Measure the voltage at the controller’s input terminals using a multimeter when the cart is off. A reading near 36V, 48V, or 72V confirms the system voltage.

Golf carts with 36V systems often have older motors, while 48V is standard for modern models. For instance, EZ-GO TXT models after 2010 typically use 48V configurations. If upgrading from lead-acid to lithium, ensure the new battery bank maintains the same voltage. Why does this matter? Mismatched voltages can overload controllers or reduce torque. A 48V lithium pack like Redway’s 48V 105Ah provides 5kWh—equivalent to eight 6V lead-acid batteries but with 60% less weight.

What battery capacity (Ah) ensures sufficient range?

Capacity determines runtime—higher Ah (e.g., 200Ah vs. 150Ah) extends driving distance. For lead-acid, aim for 180–250Ah; lithium packs often achieve similar range with 100–150Ah due to deeper discharge capability.

For example, a 48V 200Ah lead-acid bank delivers ~9.6kWh, providing 25–35 miles per charge. Lithium equivalents like a 48V 105Ah pack offer ~5kWh but maintain 80% capacity after 2,000 cycles. Pro Tip: Calculate required kWh by multiplying voltage (V) × desired range (miles) × 0.3. A 48V cart needing 30 miles requires ~14.4kWh (48 × 30 × 0.3), achievable with a 300Ah lead-acid or 150Ah lithium setup. Transitionally, lithium’s efficiency reduces energy waste, but upfront costs are higher.

Battery Type	Typical Capacity	Cycle Life
Lead-Acid	150–250Ah	500–800
Lithium-Ion	100–150Ah	2,000–5,000

Can I replace lead-acid with lithium batteries?

Yes, but verify voltage compatibility and controller settings. Lithium batteries are 30–50% lighter and tolerate deeper discharges (90% vs. 50% for lead-acid).

Swapping lead-acid for lithium requires a battery management system (BMS) to prevent over-discharge. For example, replacing six 8V lead-acid batteries with a single 48V 100Ah lithium pack simplifies wiring and maintenance. However, some controllers need reprogramming to handle lithium’s flat voltage curve. Warning: Never mix lithium and lead-acid cells in the same bank—voltage inconsistencies risk cell damage. Transitionally, lithium’s upfront cost is offset by longer lifespan and reduced charging time.

How To Test Golf Cart Battery Life?

To test golf cart battery life, evaluate voltage levels, inspect physical condition, and analyze electrolyte health. Use a multimeter to measure voltage (fully charged 12V battery should read 12.6-12.8V). Check for bulging cases or terminal corrosion. For flooded lead-acid batteries, verify electrolyte levels and specific gravity (1.265-1.299 indicates full charge). Pro Tip: Perform load tests under real operating conditions—voltage shouldn’t drop below 10.5V under load for 12V batteries.

Best EZ-GO Golf Cart Batteries for Longevity

What voltage indicates a healthy golf cart battery?

A 12V golf cart battery showing 12.6-12.8V at rest indicates full charge. During discharge, voltage shouldn’t drop below 10.5V under load. Pro Tip: Test voltage 12 hours post-charging for accurate readings—surface charge disturbs immediate measurements.

Voltage testing reveals state-of-charge but not total capacity. For 6V batteries commonly used in series configurations, multiply readings by battery count (six 6V batteries = 36V system). Consider this example: A 48V golf cart pack showing 50.9V indicates 75% charge. Transitional phrase: Beyond basic voltage checks, load testing proves essential. Use carbon pile testers to apply 300A loads—healthy batteries maintain ≥9.6V per 12V unit during 15-second tests. Warning: Never load-test batteries showing <12.0V resting voltage—recharge first to prevent damage.

⚠️ Critical: Always disconnect battery cables before testing—accidental short circuits can melt terminals.

Voltage (12V Battery)	Charge State	Action Required
12.6-12.8V	100%	None
12.4V	75%	Recharge soon
12.1V	50%	Immediate recharge

How does electrolyte inspection help assess battery health?

Electrolyte levels and specific gravity directly indicate lead-acid battery condition. Maintain fluid ¼” above plates—low levels accelerate sulfation. Use a hydrometer: 1.265-1.299 specific gravity signifies full charge.

In flooded batteries, electrolyte stratification causes false readings. Pro Tip: Equalize batteries annually—controlled overcharge mixes electrolytes. Transitional phrase: When examining electrolyte color, clear liquid indicates health while murky appearance suggests plate shedding. For instance, blackened electrolyte in multiple cells confirms irreversible capacity loss. Always top up with distilled water—tap water minerals corrode plates. Warning: Never add acid to existing electrolyte—it disturbs chemical balance.

Top Picks for Best Lithium Golf Cart Battery

What factors influence 48V EZGO golf cart speed?

Motor type, battery capacity, and controller programming are primary determinants. Series motors prioritize torque, while regen systems optimize efficiency at moderate speeds. A 48V 100Ah lithium pack sustains higher RPMs longer than lead-acid equivalents. Controllers with 500A+ output unlock 20+ mph but require reinforced wiring.

Stock EZGO TXT models use 3.3HP motors limited to 14–16 mph. Aftermarket upgrades like Alltrax XCT controllers override factory speed caps by adjusting throttle curves. Terrain matters too—a 10% incline reduces speed by 25% on carts with standard gear ratios. For example, a lithium-powered RXV with 23″ tires achieved 24 mph on flats but dropped to 18 mph climbing hills. Always verify local regulations: many communities enforce 20 mph limits for street-legal carts.

⚠️ Warning: Exceeding 25 mph risks axle damage in stock transaxles. Install heavy-duty gears if upgrading speed components.

How does motor type affect speed?

Series wound motors allow speed customization via controller tuning, whereas regen (sepex) motors self-limit RPMs. Series systems dominate aftermarket builds, supporting 400–600A surges for acceleration. Regen motors prioritize regenerative braking, capping speeds at 14–16 mph without controller overrides.

Motor Type	Max Stock Speed	Upgrade Potential
Series	14–16 mph	22–25 mph
Regen	12–14 mph	18–20 mph

For instance, a D&D Motor Systems ES-76 series motor paired with 48V lithium batteries can sustain 23 mph on flat pavement. However, regen motors like the AMD 7144 require bypassing speed sensors to unlock higher RPMs. Pro Tip: Always match motor upgrades with compatible controllers—mismatched pairs risk thermal shutdowns.

What Golf Cart Battery Lasts The Longest?

Lithium iron phosphate (LiFePO4) batteries typically last the longest for golf carts, offering 2,000–5,000 cycles versus 300–500 cycles for lead-acid. Key factors include thermal stability, deep discharge tolerance (80–100%), and low self-discharge (≤3% monthly). Trojan T-1275 lead-acid and ROCKET LONGEST series are alternatives but require frequent maintenance. For maximum lifespan, pair LiFePO4 with a compatible 14.6V LiFePO4 charger to prevent overcharging.

Top Picks for Best Lithium Golf Cart Battery

What defines a long-lasting golf cart battery?

A durable battery combines high cycle life and deep discharge resilience. LiFePO4 cells handle 80% depth-of-discharge (DoD) daily without capacity loss, while lead-acid degrades past 50% DoD. Pro Tip: Avoid exposing batteries to temperatures >45°C—heat accelerates electrolyte evaporation in lead-acid models.

Cycle life is the gold standard. For example, a LiFePO4 pack rated for 3,000 cycles at 80% DoD lasts ~8 years with daily use. Comparatively, flooded lead-acid (FLA) batteries like the Trojan T-1275 last 4–5 years under similar conditions. But what causes this disparity? Lithium’s solid-state chemistry minimizes sulfation and corrosion—two primary lead-acid failure modes. Transitional phrase: Beyond chemistry, maintenance plays a role. FLA requires monthly water topping; AGM needs terminal cleaning to prevent resistance buildup.

Factor	LiFePO4	Lead-Acid
Cycle Life	2,000–5,000	300–800
DoD Limit	80–100%	50%
Maintenance	None	Monthly

How does voltage affect golf cart battery longevity?

Higher voltage systems (e.g., 48V) reduce current draw, decreasing heat and prolonging lifespan. A 48V LiFePO4 pack running 20A lasts longer than a 36V pack pulling 28A for the same power. Pro Tip: Always balance battery banks—cell voltage deviations >0.2V trigger premature aging.

Ohm’s Law explains this: Power (W) = Voltage (V) × Current (A). Lower current at higher voltages means less stress on connectors and plates. For instance, a 48V system drawing 50A delivers 2,400W, whereas a 36V system needs 66.7A—increasing resistance losses by 33%. Transitional phrase: Practically speaking, 48V is the sweet spot for modern golf carts. Brands like ROCKET LONGEST use thicker lead plates for 12V units, but lithium’s efficiency dominates. Ever wondered why Tesla uses 400V packs? Scaled-down principles apply: higher voltage = better longevity.
