Quick Picks for Aiways Owners (By Use Case)

• Daily EV use (commute + errands): Choose AGM with solid Reserve Capacity for frequent short trips. Try H5/LN2 AGM. ~$180–$280
• Accessory‑heavy (dash cams, telematics, parked software updates): AGM H6/LN3 often offers higher Ah/RC headroom. See H6/LN3 AGM. ~$210–$330
• Cold climate: Prioritize higher CCA AGM. Browse high‑CCA AGM picks. ~$200–$350
• Hot climate or long storage: AGM/EFB handle heat and partial state‑of‑charge better than flooded. Compare EFB options. ~$160–$260
• Budget replacement (non‑AGM OK per manual): Quality EFB as a middle ground. LN2 EFB. ~$160–$230
• Garage‑kept, low mileage: Pair any new battery with a smart maintainer to maximize life. AGM maintainers. ~$30–$120

Top Battery Types for Aiways (What to Choose & Why)

Aiways Model‑Specific Buying Tips

• Aiways U5 (most markets): Commonly uses a European DIN/LN size 12‑V battery. Many owners opt for AGM H5/LN2 (≈60Ah) for robustness on short trips. ~$180–$280
• Aiways U6 (most markets): Often fits AGM H6/LN3 (≈70Ah) to support accessory loads. Verify tray space and hold‑down style before purchase. ~$210–$330
• Winter package or cold‑weather regions: Favor higher CCA ratings and consider moving up one size class if it physically fits and cables reach without strain.
• Warranty & software: If your vehicle is under warranty, stick to the specified battery tech (AGM/EFB) and keep receipts. Some trims may require a 12‑V reset or sleep procedure after replacement—follow the service manual.

Aiways Battery Fitment Cheat Sheet (Most‑Common Sizes)

Spec Targets: CCA, RC, and Warranty

CCA: Cold Cranking Amps
RC: Reserve Capacity
Tech: Flooded / EFB / AGM

• CCA: Meet or exceed OE. In cold climates, consider +50–100 CCA.
• RC / Ah: More capacity keeps the 12‑V bus alive during software updates, sentry/dash‑cam modes, or long parking.
• Technology: If the car shipped with AGM/EFB, do not downgrade.
• Warranty: Aim for 36–48 months free replacement (or your market’s equivalent).
• Dimensions & terminals: LN2 vs LN3 differ in size; verify cable reach and polarity (often EN/“European” posts).

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

• Where to buy: Online marketplaces, national auto‑parts chains, and EV‑savvy local shops.
• Pros of buying online: Easy spec comparison, fast shipping, frequent promos.
• Cons: Core returns and old‑battery disposal can be trickier—confirm pickup/recycling.
• Tip: Look for fresh date codes (within last 3–6 months) and free installation/testing offers.

How to Check Freshness & Authenticity

• Date codes: Look for a stamped/printed month‑year code (e.g., 09/25). Prefer newer stock.
• Seal/labels: No tampering, clean vent caps, crisp printing, correct model number.
• Voltage at rest: AGM ≈12.7–12.9V fully charged; ask the seller to test if possible.
• Seller reputation: Stick with known brands and highly rated sellers.

Car Battery Warranty Tips

• Register your battery purchase and keep digital copies of the receipt.
• Follow maintenance guidelines (smart charger/maintainer use) to avoid claim denials.
• Understand pro‑rated vs. free‑replacement periods; choose the longest free‑replacement you can.
• Document any charging‑system tests from a shop to support warranty claims.

Aiways Car Battery Installation Guide (DIY or Shop)

1. Prep the vehicle: Park safely, power down, open hood. Allow the EV to enter sleep mode per the manual (wait a few minutes after locking screens off).
2. Tools & safety: Gloves, 10–13mm sockets, memory saver (optional), and a 12‑V maintainer. Avoid shorting terminals.
3. Maintain memory (optional): Use an OBD‑II or 12‑V accessory memory saver. See memory savers.
4. Disconnect: Negative (–) first, then positive (+). Remove hold‑down clamp and lift the battery out vertically.
5. Install new battery: Clean tray and terminals. Place new battery, secure hold‑down, connect positive (+) first, then negative (–). Torque snugly—don’t overtighten posts.
6. Initial charge: If the new battery is below ~12.6V, top it with an AGM‑compatible charger. Smart chargers.
7. Vehicle wake‑up: Follow the manual’s power‑up procedure. Clear any transient warnings after a short drive cycle.
8. Recycle the old battery: Many sellers offer core refunds. Use proper recycling channels.

Aiways Car Battery Maintenance & Longevity

• Monthly check‑ins: Read resting voltage; charge if the vehicle sits for long periods.
• Top‑offs: Use a smart maintainer if you drive infrequently. Shop maintainers.
• Parasitic draw control: Turn off always‑on accessories when parked (dash cams, OBD dongles).
• Clean & secure: Keep terminals tight and free of corrosion (use dielectric grease sparingly).
• Software updates: Perform updates with a healthy 12‑V or while connected to a maintainer.

Signs You Need a New Battery

• Frequent low‑voltage warnings or accessory resets on startup.
• Slow door locks, dim interior lights, or infotainment restarts.
• Resting voltage under ~12.2V after a full charge (AGM) or failing a load test.
• Swollen case, leaks, or strong sulfur smell (replace immediately).

Can I replace the Aiways 12-volt auxiliary battery myself?
Yes, if you’re comfortable with basic tools and follow high-voltage safety rules: power the car down fully, wait for systems to sleep, then swap the like-for-like 12-volt battery (correct size and terminal layout). If you’re unsure or if software reset/registration is required, use an authorized service center.

What’s the difference between the traction battery and the 12-volt battery in an Aiways?
The large high-voltage traction battery powers the motor and driving range; the smaller 12-volt battery runs control modules, lights, and accessories. A weak 12-volt battery can stop the car from “waking up” even if the traction battery is charged.

How long should a Aiways car battery last?
For the 12-volt battery, expect roughly 3–5 years depending on climate and usage. For the high-voltage traction battery, most drivers see 8–15 years of usable life with gradual capacity loss; exact longevity depends on charging habits, temperature, mileage, and software thermal management.

How much is a Aiways car battery?
A replacement 12-volt battery typically costs about $120–$300 including parts and basic installation. Replacing the high-voltage traction battery is far more expensive (often several thousand dollars); most owners never pay this out-of-pocket during the warranty period unless the pack is physically damaged.

Do I need to “register” or reset anything after changing the 12-volt battery?
Some vehicles perform a self-learn after a 12-volt swap, but others benefit from a service-tool reset to clear low-voltage flags and re-initialize battery monitoring. If warning lights persist after a correct swap, have a technician run diagnostics.

Can I jump-start an Aiways if the 12-volt battery dies?
Usually yes—using the 12-volt jump points specified in the owner’s manual. Only use approved jump-start procedures; never connect external power to the high-voltage system.

How do I maximize the traction battery’s lifespan?
Avoid frequent 100% charges or deep 0% runs, minimize time spent at very high state-of-charge in hot weather, enable scheduled charging to finish near departure, keep software up to date, and store the car around 40–60% if parking for weeks.

What signs indicate my 12-volt battery is failing?
Slow or failed system wake-up, flickering screens, repeated low-voltage alerts, or the car failing to shift out of Park after sitting. Test the 12-volt battery and replace if it can’t hold charge.

Will replacing the 12-volt battery improve range?
No—range depends on the traction battery and driving conditions. However, a healthy 12-volt battery helps the car’s control systems operate reliably, which can reduce nuisance faults.

Is the traction battery covered under warranty?
Most EVs include a multi-year, high-mileage warranty for the traction battery (often with a minimum capacity retention clause). Check your Aiways warranty booklet for the exact term and capacity threshold in your region.

Bottom Line

For most Aiways U5/U6 owners, a fresh AGM in the H5/LN2 (U5) or H6/LN3 (U6) class delivers the best reliability and accessory headroom. Verify size, polarity, and tech in your manual, and pair your new battery with a smart maintainer to maximize lifespan.
