Ansmann LR44

Finally found a battery that actually keeps my car key fob working for more than a few months, and the shelf life on these seems solid. The garage door opener hasn't missed a beat since I swapped them in.

Popped them into my digital scale and the readings have been perfectly stable for weeks, unlike the last cheap ones that drifted after a few days. They even fit snugly in my car key fob without any rattling.

Set them in my pocket scale and the readings stayed consistent for weeks, no drop-off like with the old cells. Each one has that tight seal so they don’t leak.
