Important Safety Information
To ensure safe operation and prolong battery life, please observe the following precautions:
- DO NOT MIX: non-rechargeable with rechargeable batteries; fully-charged with mid- to low-charged batteries; new with old batteries; different mAh capacities; different brands. Mixing battery types or charge levels can lead to damage or undesired rapid discharge.
- Verify device compatibility with 1.2V Ni-MH batteries. Runtime may be shorter than 1.5V alkaline batteries.
- Check proper fit as Ni-MH batteries are slightly larger than alkaline batteries to comply with IEC standards.
- Replace all batteries simultaneously in a device.
- Consult the device manual for specific battery requirements.
- Use only Ni-MH specific chargers with independent charging channels and voltage monitoring to prevent overcharging or undercharging.
- Avoid timer-only chargers.
- Never use chargers designed for other battery types (like NiZn or Li-ion), as this may cause damage or leakage.
- Do not short-circuit, put into fire, heat, disassemble, or use with other battery types.
Setup and First Use
Your Amazon Basics NiMH batteries arrive pre-charged and are ready for immediate use. For optimal performance and longevity, it is recommended to fully charge them before the first extensive use, especially if they have been stored for a long period.
- Unpacking: Carefully remove the batteries from their packaging.
- Initial Charge: Insert the batteries into a compatible NiMH battery charger. Ensure correct polarity (+ and - ends).
- Charging Process: Allow the batteries to charge fully according to your charger's instructions. Most modern NiMH chargers will indicate when charging is complete.
- Insertion into Device: Once charged, insert the batteries into your electronic device, observing the correct polarity.

Maintenance and Storage
Proper maintenance ensures the longevity and performance of your rechargeable batteries:
- Cleaning: Keep battery terminals clean. Use a dry cloth to wipe off any dirt or corrosion.
- Charging Cycles: While these batteries can be recharged up to 1000 times, their capacity may gradually decrease over many cycles.
- Storage Temperature: Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures.
- Long-Term Storage: For storage longer than a few months, it is advisable to charge the batteries to about 50% capacity before storing them. Recharge them every 6-12 months to prevent deep discharge.
Troubleshooting
If you encounter issues with your batteries, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Batteries not charging. | Incorrect charger type; poor contact; battery too old/damaged. | Ensure charger is NiMH compatible. Clean battery terminals. Try a different battery or charger. |
| Short runtime in device. | Batteries not fully charged; device has high power drain; battery capacity degradation. | Ensure full charge. NiMH batteries may have shorter runtime than alkaline in some devices. Consider replacing older batteries. |
| Batteries do not fit in device. | NiMH batteries are slightly larger than alkaline. | Verify device compatibility with NiMH AA batteries. Some devices have very tight battery compartments. |
| Batteries get hot during charging. | Normal during charging; overcharging; faulty charger. | Some warmth is normal. If excessively hot, discontinue charging and check charger. Use a charger with voltage monitoring. |
