Will this AG4 battery fit my watch?
AG4 batteries are 6.8mm in diameter and 2.6mm thick. Please check your device's manual or measure your old battery to ensure compatibility. If your device requires a 6.8mm diameter button cell, AG4 is the correct size
Is this the same as LR626 or SR626SW?
Yes, AG4 is the same size as LR626 (alkaline) and SR626SW (silver oxide). Our AG4 is an alkaline battery and works as a direct replacement for both LR626 and SR626SW in most devices like watches and calculators.
Can I use AG4 instead of a 377 or 376 battery?
Yes, AG4 replaces 377 and 376 in most devices. They share the same 6.8mm diameter and 2.6mm thickness. AG4 is an affordable alkaline alternative to silver oxide versions.
