Standard Small Batteries

The standard small batteries category includes a broad range of batteries commonly found in home appliances, toys, remote controls, and other devices.

These batteries come in various sizes, shapes, and chemistries, and thus may lead the user to certain confusion regarding which battery is the proper battery equivalent/replacement for a particular device.

Standard small batteries include:

 

- Button/Coin Cell Batteries

 

- Cylindrical Batteries

 

- Lithium Non-Rechargeable 3V Button/Coin Cell Batteries
