Battery Keeper

Organize household battery stock with Battery Keeper. Add storage locations and battery batches with type, chemistry, rechargeable status and cell count. Record devices and the battery type and quantity they need.

Record battery installations and set replacements. Mark rechargeable cells as charging, then check them yourself and mark them available when ready. Review stock movement history and set a battery-change reminder for a device.

Records are stored locally on your device. This is a manual inventory, not hardware battery monitoring or optimization: it does not measure charge or control charging.

An optional one-time purchase removes ads.
