Frequently Asked Questions About Batteries

Q: What is the difference between AA batteries and AAA batteries?

A: AA and AAA refer primarily to the size of the battery; AA batteries are larger than AAA batteries, but they generally provide the same 1.5 volt output.

Q: Can I use rechargeable batteries instead of regular batteries?

A: Yes, but make sure your device is compatible with the rechargeable type, as rechargeable batteries (such as NiMH) usually only have a voltage of about 1.2 volts when fully charged, which is slightly lower than regular alkaline batteries.

Q: How can I tell if the battery is dead?

A: If the device suddenly stops working, or the light dims, responds more slowly, etc. In this case, it may mean that your battery is exhausted or needs to be replaced with a new one.

Q: Can batteries of different brands be mixed?

A: It is best not to mix them, because batteries from different brands may have differences in voltage, chemical composition, etc., which may easily cause battery leakage or deterioration of device performance.

Q: What should I do with old batteries?

A: You can take old or scrap batteries to a local designated recycling station, or participate in hazardous recycling activities organized by the community to avoid polluting the environment.
