FAQs
How many times can these batteries be recharged?
These Amazon Basics rechargeable AA NiMH batteries can be recharged up to 400 times.
Are these batteries pre-charged?
Yes, these batteries come pre-charged and are ready to use right out of the package.
Can I use these batteries in any device that takes AA batteries?
You can use them in most devices that take AA batteries, but it's best to verify that your device is compatible with 1.2V NiMH rechargeable batteries. Also, note that NiMH batteries are slightly larger than alkaline batteries.
What type of charger should I use?
You must use a charger specifically designed for Ni-MH rechargeable batteries. Ensure it has independent charging channels and voltage monitoring to prevent damage.
Will these batteries last as long as alkaline batteries?
In high-drain devices, they often last as long or longer due to their high capacity. However, in some specific low-drain devices, their runtime may be slightly shorter than that of 1.5V alkaline batteries.
What does 'low self-discharge' mean?
Low self-discharge means the batteries retain a high percentage of their charge even when stored for extended periods, making them more reliable when you need them after long-term storage.
Can I mix these with other rechargeable batteries?
It is not recommended to mix batteries of different capacities, brands, charge levels, or types (rechargeable vs. non-rechargeable) in the same device or charger, as this can lead to poor performance or damage.
Troubleshooting
Batteries do not charge
Ensure you are using a Ni-MH specific charger with independent channels. Check that the batteries are properly seated in the charger and that the charger is plugged in. Clean the battery terminals and charger contacts if they appear dirty.
Device not powering on or working intermittently
Verify that the batteries are inserted correctly with the correct polarity (+/-). Ensure the batteries are adequately charged. Try a different set of known-good batteries or a fresh alkaline battery to test the device. Clean the battery contacts in the device.
Batteries seem to lose charge quickly
Ensure the batteries are fully charged before use. Check if the device is a high-drain device where runtime may be shorter than expected. Ensure you are not mixing these batteries with older or lower-capacity batteries. Consider if the device is compatible with 1.2V NiMH batteries.
Battery is physically damaged or leaking
Immediately remove the damaged battery from the device and the charger. Do not attempt to recharge or use a damaged battery. Dispose of it properly according to local regulations for battery disposal.
Charger indicates an error or fault
Consult your charger's manual for specific error codes. Ensure you are using a charger compatible only with Ni-MH batteries. Try charging a different set of Ni-MH batteries to see if the issue persists with the charger or the batteries.

Setup, Compatibility & Care
Setup: These batteries come pre-charged and ready to use. Simply insert them into your device following the correct polarity (+/-).
Compatibility:
- Device Compatibility: Verify that your device is compatible with 1.2V Ni-MH rechargeable batteries. Check the device's manual or manufacturer's specifications.
- Charger Compatibility: Use only a charger specifically designed for Ni-MH batteries. Ensure the charger has independent charging channels and voltage monitoring to prevent overcharging or undercharging. Never use chargers designed for other battery types (e.g., NiZn, Li-ion) or timer-only chargers, as this can cause damage or leakage.
- Mixing: DO NOT MIX:
- Non-rechargeable batteries with rechargeable ones.
- Fully charged batteries with mid- to low-charged batteries.
- New batteries with old batteries.
- Batteries with different mAh capacities.
- Batteries from different brands (though Amazon Basics are generally reliable, best practice is to keep them separate if mixing is unavoidable).
Care:
- Storage: Store batteries in a cool, dry place. For long-term storage, it's recommended to charge them to about 50% capacity and keep them in a battery case.
- Cleaning: If the battery terminals appear dirty, gently wipe them with a clean, dry cloth or a pencil eraser. Ensure the battery is removed from the device before cleaning.
- Charging: Always follow the instructions provided with your Ni-MH specific charger. Avoid leaving batteries in the charger indefinitely after charging is complete.
- Replacement: Replace all batteries in a device simultaneously. Do not mix old and new batteries, or batteries with different charge levels.
