Energizer A23 12 volt alkaline

Was looking for a battery with a solid power-to-weight ratio for a key fob, and this one fits perfectly. It’s been running strong for weeks without any drop-off in signal range.

My watch stopped losing time after I swapped in this little A23—the 12 volts really hold up over months, not weeks. The high power-to-weight ratio means it doesn't add bulk to the case, which I appreciate when I'm checking the date at a glance.

Installed this in my garage door remote and it’s working perfectly. The battery fits securely and the high power-to-weight ratio seems to be delivering consistent performance so far.
