What devices take an AG5 / LR754 cell?

Small watches, calculators, laser pointers, toys and some remote controls use this size. Check your device's battery compartment for AG5, LR754, LR48 or 393 labeling before buying.

Is AG5 the same as LR754 and LR48?

Yes. AG5, LR754 and LR48 are different names for the same button cell size. The MEDca cells are labeled to cover all three.

Are these batteries rechargeable?

No. They are 1.5V alkaline button cells and should be replaced, not recharged. Recharging an alkaline cell can cause leakage or rupture.

How should I store a large pack?

Keep the cells in their packaging in a cool, dry place away from metal objects. Alkaline button cells lose charge slowly over years, so use the oldest first.

Can these leak in a watch?

Any alkaline cell can leak if left in a device until fully drained. Remove dead cells promptly and avoid storing devices with old batteries installed.
