Day: July 17, 2025

For a 2005 National RV Tropi-Cal, the correct battery depends on original specifications, typically 12V deep-cycle lead-acid or AGM batteries. Identify the existing battery’s group size (e.g., Group 24, 27, or 31), capacity (Ah), and terminal configuration. Lithium (LiFePO4) upgrades are viable if voltage matches (12V nominal) and BMS supports alternator/charger compatibility. Verify physical dimensions and reserve capacity (RC) requirements—most RV batteries need 180–220Ah for sustained off-grid use. Pro Tip: Cross-reference OEM manuals or contact National RV’s parts department for verified specs. How Long Will an EZGO Golf Cart Last?

What battery type suits a 2005 National RV Tropi-Cal?

The 2005 Tropi-Cal typically used Group 27 or 31 lead-acid batteries (12V, 100–125Ah). AGM or lithium upgrades require verifying charge voltage thresholds (14.4–14.6V for AGM, 14.2–14.6V for LiFePO4). Deep-cycle models with 180–220 RC (reserve capacity) ensure stable power for lights, refrigeration, and appliances.

Beyond voltage compatibility, AGM batteries excel in vibration resistance, critical for RVs. Lithium options like LiFePO4 reduce weight by 50% but require a compatible charger. For instance, replacing two Group 27 lead-acid batteries (130Ah total) with a single 200Ah LiFePO4 unit saves 60 lbs. What’s the catch? Lithium’s upfront cost is 3× higher, but lifespan exceeds 2,000 cycles versus 500 for lead-acid. Pro Tip: Use a battery monitor to track state of charge (SOC) and prevent deep discharges below 20%.

How to confirm battery group size for a 2005 RV?

Measure the battery tray dimensions (LxWxH) and terminal orientation. Group 27 measures 12.4×6.8×9.4 inches, while Group 31 is 13×6.8×9.4 inches. Terminal posts are typically top-mounted for RVs. Mismatched sizes risk installation failures or cable strain.

If original labels are illegible, cross-check the vehicle’s manual or consult National RV’s parts database. For example, the Tropi-Cal’s chassis often uses 12V dual-battery setups with Group 31. Pro Tip: Snap photos of existing batteries’ labels (e.g., “BCI Group 27”) for parts suppliers. If upgrading to lithium, ensure the BMS supports parallel configurations for expanded capacity.

Where can I find warranty details online?

Manufacturer websites centralize warranty policies, often requiring serial numbers for validation. Brands like Tesla Energy and Redway Battery list PDF guides covering prorated replacements, transferability, and claims procedures. Pro Tip: Screenshot your purchase date and invoice for faster claim processing.

Online portals like Redway Battery’s “Warranty Checker” let users input serial numbers to verify eligibility. Look for sections titled “Limited Warranty” or “Product Support”—these often define capacity guarantees (e.g., 80% after 1,000 cycles). What happens if your battery fails prematurely? For example, Redway’s 5-year warranty covers defects but excludes water damage. Always confirm if your application (e.g., solar storage vs. EV) aligns with coverage. Pro Tip: Register your battery online post-purchase—many brands extend warranty periods for registered users. Companies like Duracell and Battle Born also offer live chat support for clarifying ambiguous terms.

How do physical documents provide warranty info?

User manuals and warranty cards included in packaging outline return policies and service centers. Retailers like Home Depot often attach warranty slips to receipts. Pro Tip: Store physical copies in a fireproof safe—digital backups can get lost during hardware failures.

Physical documents typically include QR codes or URLs directing you to the manufacturer’s claim portal. For instance, Optima Batteries prints a 12-digit code on labels for warranty activation. However, thermal fading can make these codes unreadable—photocopy them immediately. Why risk losing coverage? Consider a flooded lead-acid battery’s warranty card: it might exclude sulfation caused by partial charging. Pro Tip: Laminate paper warranties to prevent moisture damage. Retailers like Costco sometimes handle replacements directly, bypassing manufacturers. Check for retailer-specific terms if bought through Amazon or Walmart.

What’s covered under standard battery warranties?

Warranties generally cover manufacturing defects like faulty BMS or cell imbalance. Lithium-ion warranties often guarantee capacity retention (e.g., ≥70% after 2,000 cycles). Physical damage or misuse (e.g., over-discharging) is usually excluded. Pro Tip: Document charging habits—some brands deny claims if logs show frequent overcharging.

Coverage varies by chemistry: LiFePO4 batteries often have longer warranties (e.g., 5–10 years) than lead-acid (1–3 years). For example, a LiFePO4 battery with a 7-year warranty might require annual capacity tests. But how do you prove a defect? Brands like Redway Battery may request cycle count data from Bluetooth-connected BMS. Pro Tip: Use manufacturer-approved chargers—third-party units void warranties if they cause voltage spikes. Automotive batteries like AGM sometimes include free replacement within the first year, then prorated credits. Always check regional differences; EU warranties are often more consumer-friendly than US policies.

FAQs

What Makes Duracell Marine Batteries a Top Choice for Boaters?

Maintaining your golf cart battery involves regular watering (for lead-acid), voltage checks, and avoiding full discharges. Use distilled water to refill cells monthly and store at 50–70% charge in cool, dry environments. Lithium-ion (LiFePO4) batteries require no watering but need balanced charging. Pro Tip: Clean terminals with baking soda paste to prevent corrosion, ensuring 10+ years for LiFePO4 or 4–6 years for lead-acid.

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

How Often Should You Check Water Levels in Lead-Acid Batteries?

Check lead-acid battery water levels every 2-4 weeks, topping up with distilled water to cover plates. Overfilling risks acid spillage, while underfilling accelerates sulfation. Post-charging is ideal since water expands during cycles. Pro Tip: Mark fill lines on translucent batteries for quick visual checks.

Deep Dive: Lead-acid batteries lose water through electrolysis, especially in hot climates or during fast charging. Maintain water ¼” above plates—roughly ½” below vent wells. Use a flashlight to inspect levels; opaque batteries require removal of caps. For example, a 48V golf cart system with six 8V batteries needs individual cell checks. Overwatering dilutes electrolyte, reducing specific gravity below 1.225, while low levels expose plates, causing irreversible sulfation. Transitional Tip: Pair monthly water checks with terminal cleaning to avoid resistance buildup. But what if you forget? One missed refill in summer can evaporate 20% of water, slashing cycle life by 15%.

What Charging Practices Prolong Golf Cart Battery Life?

Charge lead-acid batteries after 50% discharge (≥48.5V for 48V systems) using a 3-stage charger. Lithium batteries handle partial charges but benefit from monthly full cycles. Avoid overcharging lead-acid beyond 62V (48V system), which warps plates.

Deep Dive: Lead-acid chargers should deliver 10–30% of battery capacity (e.g., 10A for 100Ah). For a 48V system, bulk charge to 58V, absorb at 59V, then float at 54V. Practically speaking, charging immediately after use prevents sulfation. Lithium systems use CC-CV charging: 58.4V bulk, then hold at 54V. An example: Trojan T-105 requires 8–10 hours for full charge, whereas LiFePO4 reaches 80% in 2 hours. Transitional Pro Tip: For lead-acid, equalize every 30 cycles by charging at 62V for 2 hours to desulfate. But why does this matter? Skipping equalization reduces capacity by 40% in 12 months.

How Does Temperature Affect Battery Maintenance?

Heat above 90°F (32°C) increases water loss and sulfation, while freezing temperatures reduce capacity 20–30%. Store batteries at 50–80°F (10–27°C). Pro Tip: Insulate battery compartments in winter but ensure ventilation in summer.

Deep Dive: At 95°F, lead-acid self-discharge doubles to 10% monthly, requiring more frequent charging. Lithium batteries fare better, losing just 2–3% monthly. For example, a golf cart stored in a garage at 40°F needs trickle charging every 3 weeks versus 6 weeks at 70°F. Transitional Insight: Use thermal blankets in sub-zero climates to maintain efficiency. But what if your cart is left outdoors? Direct sun exposure can heat batteries to 120°F, cutting lifespan by half. Always park in shade or use reflective covers.

Can You Store Golf Cart Batteries Long-Term Without Damage?

Store lead-acid at 50–70% charge (12.4–12.7V per 12V battery) and lithium at 30–60% (3.4–3.6V per cell). Disconnect terminals to prevent parasitic drain. Pro Tip: For 6+ month storage, use a maintainer delivering 13.6V (lead-acid) or 54V (lithium).

Deep Dive: A fully charged lead-acid battery left for 3 months drops to 60% charge, risking sulfation. Lithium self-discharges <5% monthly, making it better for seasonal storage. For example, a 48V lithium pack stored at 53V (3.3V/cell) retains 90% capacity after 8 months. Practical Tip: Recharge lead-acid every 60 days and lithium every 6 months. Transitional Note: Always store in dry areas—humidity corrodes terminals. But how critical is voltage? Storing lead-acid below 12.2V risks 50% capacity loss in a year.

Why Is Voltage Monitoring Crucial for Battery Health?

Voltage reveals state of charge and cell balance. A 48V lead-acid system should read 50.9V (100%) to 48.4V (50%). Lithium stays stable (51–54V) until depletion. Pro Tip: Use a digital voltmeter monthly to catch failing cells early.

Deep Dive: A 0.5V drop in one 8V lead-acid cell indicates sulfation or shorting. For lithium, cell imbalance beyond 0.1V triggers BMS shutdowns. Imagine a 48V lithium pack: If three cells at 3.4V and one at 2.9V, the BMS disables charging to prevent damage. Transitional Tip: Log voltage readings monthly—sudden drops signal aging. But what’s the cost of neglect? Unbalanced lead-acid cells can overwork the charger, shortening its lifespan by 30%.

What Are Signs Your Golf Cart Battery Needs Replacement?

Declining range (≤60% original), swollen cases, or voltage drop below 46V (48V system) indicate replacement. Lead-acid lasts 4–6 years; lithium 10+ years. Pro Tip: Test capacity annually—a 100Ah battery under 70Ah needs retirement.

Deep Dive: Load test lead-acid by discharging at 50A while monitoring voltage. If 48V drops to 44V in <1 hour, replace the pack. Lithium shows gradual capacity fade—below 80% warrants replacement. For example, a 5-year-old lead-acid cart struggling uphill likely has dead cells. Transitional Warning: Swollen batteries risk acid leaks—isolate and recycle immediately. But why not wait for total failure? Weak cells strain others, causing cascading failures costing 2x replacement.

FAQs

How Long Will an EZGO Golf Cart Last?

Key signs for golf cart battery replacement include reduced driving range (30-40% less distance), voltage drops below 80% capacity under load, swollen cases from overheating, and corrosion on terminals. Lead-acid batteries typically last 4–6 years; LiFePO4 lasts 8–12 years but shows gradual capacity decline. Immediate replacement is critical if voltage per cell dips below 1.75V (lead-acid) or 2.5V (LiFePO4) during operation.

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

How does reduced range indicate battery failure?

Reduced range directly reflects capacity loss from sulfation (lead-acid) or lithium plating (LiFePO4). A 48V system traveling 18 miles when new dropping to 10–12 miles signals 30% capacity degradation, often accompanied by slower hill-climbing speeds.

Capacity fade occurs when chemical reactions weaken due to age, deep discharges, or improper charging. For lead-acid, resting voltage below 48.4V (12hrs post-charge) confirms degradation. LiFePO4 packs with BMS faults may show “full charge” falsely. Pro Tip: Conduct a load test—measure voltage while driving uphill. If 48V drops to ≤42V under load, replacement is urgent. Think of it like a car engine losing horsepower: even if it starts, it can’t maintain speed under stress.

What voltage drops signal replacement time?

Voltage drops below 80% nominal under load indicate irreversible damage. For 48V lead-acid, sub-44V during operation suggests cell failure; LiFePO4 systems under 46V require immediate attention.

Voltage sag reflects internal resistance buildup. A healthy 48V lead-acid battery maintains 50–52V at full charge but drops to 46–48V under load. Degraded units plummet to 42–44V, risking motor damage. Pro Tip: Use a digital voltmeter during acceleration—readings below manufacturer specs for 3 consecutive rides mean replacement. Imagine trying to drink a thick milkshake through a narrow straw: voltage is the straw width—narrower (lower voltage) means less energy flow.

Why do charging times increase as batteries age?

Extended charging stems from higher internal resistance and reduced electrolyte efficiency. Lead-acid batteries needing 8hrs instead of 6hrs have severe sulfation; LiFePO4 packs with BMS errors may charge slower to prevent cell imbalance.

Aging batteries struggle to absorb charge efficiently. Lead-acid sulfation creates insulating lead sulfate crystals, while LiFePO4 cells with degraded anodes require longer CV charging phases. Pro Tip: Track charge cycles—if your 48V battery exceeds 10hrs regularly, test individual cell voltages. For example, a golf cart charger stuck in bulk mode (constant current) beyond 70% State of Charge signals cell imbalance. It’s like filling a bucket with holes—more time needed to reach the top.

How does physical damage affect performance?

Cracked cases, swollen sides, or terminal corrosion create internal short circuits and resistance spikes. Bulging LiFePO4 cells indicate thermal runaway risk; corroded terminals reduce current flow by 20–40%.

Physical damage often follows overcharging or impacts. Swollen lead-acid batteries leak sulfuric acid, while distorted LiFePO4 cells risk electrolyte leakage. Pro Tip: Clean terminals quarterly with baking soda paste—corrosion adds resistance equivalent to a 10W parasitic load. Imagine a highway with roadblocks: physical damage acts like traffic jams for electrons, slowing entire system performance.

Pro Tip: Insulate battery compartments in sub-zero climates to maintain >10°C during charging.

Beyond basic temperature ratings, the ABP-AEDP31CS employs carbon-enhanced electrodes to lower internal resistance—critical for high-current starts in winter. At -18°C, it retains 85% of its rated CCA versus 60% in conventional batteries. But why does heat matter less here? AGM’s sealed structure prevents electrolyte evaporation, allowing stable performance up to 60°C. A real-world test in Arizona showed 2,000+ engine cycles without voltage sag. However, avoid direct sun exposure: surface temps above 75°C trigger BMS safeguards, disconnecting the battery.

What makes the ABP-AEDP31CS suitable for APUs?

Its low self-discharge rate (3% monthly) ensures APUs remain operational during 14-day rests. The 31Ah capacity powers 300W loads for 1.2 hours, supporting HVAC and refrigeration units. Deep-cycle capability (50% DoD) suits daily APU cycling without capacity fade.

Practically speaking, APUs demand batteries that handle both starting surges and deep discharges. The ABP-AEDP31CS uses dual-purpose AGM construction: spiral cells for burst current and flat plates for sustained energy delivery. How does this compare to lithium alternatives? While LiFePO4 offers higher cycles, AGM’s lower upfront cost and compatibility with existing 12V systems make it preferred. For instance, a refrigerated trailer using this battery maintained -20°C for 8 hours during a grid outage. Always connect APUs via a dedicated 150A fuse to prevent overloads.

What Makes Duracell Marine Batteries a Top Choice for Boaters?

How to maintain the ABP-AEDP31CS for maximum lifespan?

Keep terminals clean using anti-corrosion spray, and recharge when voltage drops below 12.4V (50% SoC). Use three-stage chargers with AGM profiles (bulk: 14.4V, absorption: 13.8V, float: 13.2V). Pro Tip: Perform capacity tests biannually—replace if Ah drops below 24.

AGM batteries thrive on consistent voltage. Overcharging above 14.8V causes grid corrosion, while undercharging (<12V) leads to sulfation. A smart charger with temperature compensation adjusts voltage based on ambient conditions—vital for trucks crossing climate zones. But what if you lack a smart charger? Prioritize absorption phase duration: 4–8 hours at 13.8V ensures full saturation. For example, a logistics company extended battery life by 18 months using scheduled desulfation cycles. Avoid storing near engines; heat accelerates self-discharge by 50%.

A 4D-GEL Marine RV battery is a sealed lead-acid (SLA) battery using gel electrolytes instead of liquid acid, designed for deep-cycle use in marine vessels and RVs. These batteries feature vibration resistance, spill-proof construction, and handle 600–800 cycles at 50% depth of discharge (DoD). With typical capacities of 180–220Ah, they charge at 14.1–14.4V (absorption) and 13.8V (float), lasting 4–6 years with proper maintenance.

What Makes the EverStart Maxx Group 29DC Marine Battery Stand Out?

What defines a 4D-GEL battery’s core technology?

4D-GEL batteries use thixotropic gel electrolytes (sulfuric acid + silica) immobilizing liquid, preventing leaks. Their reinforced grids (calcium-tin alloys) minimize corrosion, sustaining 1,500–3,000 cranking amps. Pro Tip: Never charge above 14.7V—gel batteries risk voids forming, causing permanent capacity loss.

Beyond basic chemistry, 4D-GEL models excel in structural resilience. Their ABS cases withstand 30–50 psi impacts, and internal gas recombination achieves 99% efficiency, eliminating water topping. For example, a 200Ah 12V 4D-GEL battery powers a 1,500W RV inverter for 6–8 hours. But why choose gel over AGM? Gel’s lower self-discharge (3% monthly) beats AGM’s 5%, ideal for seasonal vehicles. However, they’re 15–20% heavier; a 4D-GEL weighs 120–150 lbs versus 100–130 lbs for AGM. Always use temperature-compensated chargers—gel’s thermal sensitivity demands ±0.03V/°C adjustments to prevent under/overcharging.

How does 4D-GEL compare to AGM in marine/RV use?

4D-GEL batteries offer deeper cycling (80% DoD vs. AGM’s 50%) but have lower charge acceptance (0.15C vs. 0.3C). AGM suits high-power bursts; GEL excels in slow, steady discharges.

When selecting between these technologies, consider application demands. AGM batteries deliver 2–3x higher peak currents—vital for trolling motors needing sudden thrusts. Yet GEL’s cycle longevity shines in solar/RV setups with daily 40–60% DoD cycles. For instance, a 4D-GEL battery in an RV solar bank lasts 7 years versus AGM’s 5 years under identical use. But what about cost? GEL carries a 25–30% premium over AGM—budget around $400–$550 for 200Ah models. Pro Tip: AGM handles sub-zero starts better; GEL’s gel stiffens below -15°C, temporarily reducing capacity.

What factors determine 4D-GEL battery lifespan?

Key lifespan factors include temperature control (ideally 20–25°C), discharge depth management, and correct charging voltages. Overdischarging below 10.5V accelerates grid corrosion.

Practically speaking, temperature swings are a silent killer. Operating at 35°C slashes lifespan by 50%—use insulated battery boxes in engine compartments. Moreover, pairing with compatible chargers matters; a 14.4V absorption phase ensures full rehydration without overvoltage. For example, a 4D-GEL kept at 30% average DoD lasts 8 years, while 70% DoD cuts it to 3 years. Pro Tip: Equalize GEL batteries every 6 months at 15.5V for 2–4 hours to balance cell voltages—though only if the manufacturer permits it.

Can you charge 4D-GEL batteries with standard marine chargers?

Only if the charger has a gel-specific profile. Standard wet-cell chargers apply 14.8V+ absorption, damaging gel’s chemical matrix.

Most modern three-stage chargers support selectable modes. Confirm yours has a gel setting with 14.4V max absorption. But why risk it? Mismatched chargers cause bubble formation in gel electrolytes, creating voids that reduce active material contact. For instance, using a wet-cell charger degrades a 200Ah GEL battery to 150Ah within 10 cycles. Always verify voltage settings—even a 0.5V overcharge reduces lifespan by 30%.

Why choose 4D-GEL over flooded lead-acid for RVs?

4D-GEL batteries are maintenance-free and tolerate tilting up to 45°, unlike flooded batteries requiring venting and water refills. They also emit 90% less hydrogen gas.

Imagine navigating rough terrain—flooded batteries risk acid spills, whereas 4D-GEL’s sealed design remains inert. Their deep-cycle capability also supports appliances like microwaves or air conditioners longer. A 220Ah GEL battery provides 1.3kWh usable energy (50% DoD), enough for 8 hours of RV lighting. Pro Tip: Mount GEL batteries sideways to save space—their immobilized gel won’t leak if orientation shifts.

These tools use algorithms combining user inputs, battery databases, and load profiles to match specs. For EVs, factors like peak current and duty cycles refine results. Pro Tip: Update the tool’s database quarterly—new battery models emerge constantly.

Battery Finder Tools typically start with voltage and capacity inputs, but advanced systems go deeper. For instance, an electric wheelchair requiring 48V 30Ah with 500+ cycles narrows options to LiFePO4 or high-end AGM. The tool then filters by dimensions, terminal types, and certifications like UL. Why does chemistry matter? Lithium batteries handle deeper discharges than lead-acid, affecting longevity in high-drain apps. Example: A 12V 100Ah marine battery search might prioritize dual-purpose (starting/deep cycle) AGM if the tool detects engine-start needs. Transitional systems even calculate weight distribution impacts for RV installations.

Can these tools handle custom battery packs?

Premium Battery Finders support custom configurations by adjusting cell arrangements and BMS specs. They’re ideal for robotics or solar projects needing non-standard voltages.

For bespoke setups, tools like Redway’s PRO Builder let users input series/parallel cell counts, max discharge rates, and even connector types. Imagine designing a 24V 200Ah LiFePO4 pack: the tool calculates 8x 3.2V cells in series, suggests a 100A BMS, and warns against cells with <0.5C discharge rates. Pro Tip: Always add 20% capacity buffer for unexpected load spikes. However, does this work for ultra-high-current apps? Some tools limit outputs to 500A continuous—beyond that, manual engineering is safer. Transitional algorithms might recommend prismatic cells over cylindrical ones for better thermal performance in stationary storage.

What inputs are critical for accuracy?

Key inputs include operating temperature, daily energy use, and peak power draws. Oversights here cause undersized batteries.

Missing peak current needs is the #1 error. A forklift drawing 300A bursts needs batteries with 5C discharge ratings—ordinary 1C cells would sag voltage dangerously. Tools factoring in ambient temperature adjust chemistry suggestions; LiFePO4 outperforms lead-acid in -20°C climates. Example: Inputting “daily 2kWh consumption” prompts recommendations like 24V 100Ah with 80% DoD. But what if loads are intermittent? Sophisticated tools apply Peukert’s equation for lead-acid or SOC curves for lithium. Transitional logic here prevents overpaying for unnecessary capacity.

What distinguishes DC24MF from standard marine batteries?

The DC24MF employs LiFePO4 cell architecture instead of traditional lead-acid, achieving 3,000-5,000 cycles at 80% depth of discharge. Unlike flooded batteries requiring weekly maintenance, its sealed design operates maintenance-free in 0°-45°C environments. Real-world example: A 24V 300Ah DC24MF powers a 1,200W RV refrigerator for 60+ hours versus 32 hours with AGM equivalents.

How does voltage configuration impact marine applications?

24V systems reduce current draw by 50% compared to 12V when powering 3kW+ equipment like bow thrusters or inverters. This minimizes voltage drop across long cable runs common in boats over 30 feet. For example, a 24V 500Ah bank running a 2.5kW windlass demonstrates 18% less energy loss than 12V equivalents over 15-meter wiring.

What solar compatibility features exist?

These batteries accept 14.6-29.2V solar input with integrated MPPT tolerance, enabling direct panel pairing without external controllers in 400W arrays. Built-in low-temperature charging protection prevents damage below -20°C – crucial for alpine RVs. Pro Tip: When sizing solar systems, allow 1.2x battery capacity (e.g., 580W array for 24V/300Ah) to account for cloudy-day recharge needs.

FAQs

What Is the Best RV Battery for Jayco RVs?

To find the correct battery for a 2004 National RV Tropi-Cal, start by identifying the required specifications through existing battery labels or owner’s manuals. Look for voltage (typically 12V for RVs), capacity (Ah), and group size (e.g., Group 24, 27, or 31). Deep-cycle batteries are preferred for RVs due to their ability to handle sustained power demands for appliances and lighting. AGM or lithium-ion batteries offer better durability and maintenance-free operation compared to traditional lead-acid. Verify terminal positions and physical dimensions to ensure compatibility with the RV’s battery compartment.

What battery type suits RVs like the Tropi-Cal?

Deep-cycle lead-acid or AGM batteries are standard for RVs, providing reliable power for lights, refrigerators, and inverters. The Tropi-Cal likely uses 12V batteries with 80–200Ah capacity, depending on energy needs. Pro Tip: Lithium-ion batteries (e.g., LiFePO4) reduce weight by 40% and double lifespan but require compatible charging systems.

How to interpret battery labels?

Labels show group size (e.g., Group 31), CCA (cold cranking amps), and RC (reserve capacity). For example, “Group 27DC, 120Ah” indicates a 27-series deep-cycle battery with 120 amp-hours. Transitionally, group size ensures physical fit, while RC (minutes at 25A discharge) determines runtime. Check terminal type (top-post vs. side-post) to match cables.
