Leapmotor Battery Fitment Cheat Sheet (Most‑Common Sizes)

Spec Targets: CCA, RC, and Warranty

• CCA: Meet or exceed OE CCA. EVs care more about stable voltage than massive CCA, but cold climates benefit from +50–100 CCA over minimum.
• RC: Higher RC sustains lights/HVAC and smart systems during short trips and software updates.
• Technology: If OE was EFB/AGM, don’t downgrade. Upgrading Flooded → EFB/AGM is okay.
• Warranty: Aim for 36+ months free replacement (or best available in your region).
• Dimensions & terminals: DIN H‑sizes (H4/H5/H6) map to LN codes (LN1/LN2/LN3). Confirm clamp type and polarity.

Best Car Battery Brands for Leapmotor & Where‑to‑Buy

• Amazon: Fast delivery, broad selection, easy returns. Check fresh stock and seller ratings. Browse DIN batteries.
• Authorized dealer: Correct spec matching and ECU reset service; prices may be higher.
• Local battery specialist: Can test/fit on the spot; ask about pro‑rated vs free‑replacement warranty.

How to Check Freshness & Authenticity

• Date codes: Choose batteries manufactured within the last 3–6 months when possible.
• Seals & labels: Inspect QR/holograms; avoid scratched‑off or mismatched stickers.
• Open‑circuit voltage: Healthy AGM ≈ 12.7–12.9V, EFB ≈ 12.6–12.7V before installation.
• Weight check: Underspec counterfeits may be suspiciously light compared to published weights.
• Authorized sellers: Prefer official store fronts or well‑rated sellers on marketplaces.

Car Battery Warranty Tips

• Clarify free replacement term vs any pro‑rated period.
• Keep purchase invoice and installation record; snap a photo of the receipt and battery label.
• Register the product online if available to streamline claims.
• Follow maintenance requirements (charge voltage, no deep discharge) to avoid voiding coverage.

Leapmotor Car Battery Installation Guide (DIY or Shop)

1. Preserve memory (optional but recommended): Use a 12V OBD memory saver to keep settings.
2. Power down: Park safely, turn off the car, wait a few minutes for ECUs to sleep.
3. Access the battery: Most Leapmotor models mount the 12V under the hood; remove covers as needed.
4. Disconnect negative (-) first, then positive (+). Note any vent tube or sensor leads.
5. Remove the hold‑down bracket; lift the battery with proper grips.
6. Clean terminals and tray; check for corrosion or loose grounds.
7. Install the new battery: Seat firmly, reconnect venting if applicable, refit hold‑down.
8. Reconnect positive (+) then negative (-); tighten to spec.
9. ECU relearn: Wake the vehicle, lock/unlock, and let it idle/boot systems. Some models may require a BMS reset or scan tool—your dealer or shop can perform this if needed.
10. Verify: Check clock, windows, drive‑mode memory, and error messages. Clear any transient warnings after a short drive.

Leapmotor Car Battery Maintenance & Longevity

• Use a smart charger/maintainer (AGM‑compatible) if the vehicle sits for extended periods. See smart maintainers.
• Avoid deep discharges—EVs still rely on the 12V to wake HV systems.
• Keep terminals tight and clean; treat with dielectric grease to reduce corrosion.
• Software updates: After long updates, give the car a proper drive so the DC‑DC can recharge the 12V.
• Seasonal checks: Measure resting voltage monthly in cold/hot seasons.

Signs You Need a New Battery

• Random ECU or infotainment resets; intermittent start‑up/wake issues.
• Dim interior lights or slow power windows with ignition on.
• Frequent low‑voltage warnings; trouble after short trips.
• Age 3–5 years (AGM/EFB) or earlier in harsh climates.

XPeng Car Battery FAQs

What “battery” does an XPeng have—high-voltage pack or 12V?
XPeng EVs use a large high-voltage traction battery to power the motor and a separate 12V auxiliary battery for computers, locks, and lights.

How long should a XPeng car battery last?
The high-voltage traction battery commonly lasts 8–12+ years (or well over 160,000 km) under normal use; the 12V auxiliary battery typically lasts 3–5 years depending on climate and driving patterns.

How much is a XPeng car battery?
A replacement high-voltage traction battery can range widely by capacity and region (often five figures in USD-equivalent); module-level repairs are sometimes cheaper. A standard 12V auxiliary battery usually costs about $100–$300 plus installation.

What drives battery life on an XPeng?
Fast-charging frequency, high/low temperature exposure, repeated 0–100% cycling, sustained 100% parking, and aggressive driving all influence long-term degradation.

How should I charge daily to reduce degradation?
For everyday use, keep the state of charge roughly 20–80% and reserve 100% charges for trips. Avoid leaving the car parked at 0% or 100% for long periods.

Can I use DC fast charging all the time?
Occasional DC fast charging is fine; relying on it for most sessions can increase cell wear. Mix in AC/home charging when possible.

What charging speeds can XPeng support?
It varies by model and battery option; newer XPeng models support high-rate DC fast charging on compatible stations, while AC charging is typically up to ~7–11 kW with home wallboxes.

How does cold or hot weather affect range and battery health?
Cold reduces available power and range temporarily; heat accelerates long-term wear. Pre-conditioning the cabin/battery and parking in shaded or temperature-controlled areas helps.

Do I need to “balance” or calibrate the battery?
Let the car occasionally run through a full cycle window (not frequently) and leave it plugged in after charging so the Battery Management System can balance cells automatically.

What are signs of battery degradation or issues?
Noticeable range loss at the same driving conditions, irregular state-of-charge readings, frequent thermal limiting, or warnings on the dash indicate the system should be checked.

Does XPeng’s warranty cover the traction battery?
XPeng typically provides a multi-year, high-mileage warranty on the high-voltage pack; details vary by country and model, so check your local warranty booklet or dealer.

How do I replace the 12V battery on an XPeng?
Use a correct-spec 12V unit and follow the car’s power-down procedure; some models may require system resets after replacement—if unsure, have a qualified EV technician handle it.

Is home charging safe for the battery?
Yes—use a properly installed EVSE/wallbox, keep ventilation clear, and follow the recommended current limits and charge schedules provided in the owner’s manual.

Can I store my XPeng for several weeks?
Store around 40–60% state of charge, leave the vehicle connected if the manual allows, and enable any long-term storage modes to minimize auxiliary draw.

Where can I find official XPeng battery specs and guidance?
Consult the owner’s manual for your specific model and region or contact an authorized XPeng service center for the latest, model-accurate information.

Bottom Line:
Match the original technology (EFB/AGM), choose the correct DIN size (H4/H5/H6 as labeled), and prioritize reserve capacity if you drive short trips with heavy electronics. For EREV models, stick with AGM and equal‑or‑better specs. When in doubt, select a reputable AGM in the same size code as your original and verify polarity and mounting.
