ANSMANN CR1620

My car key fob stopped working, so I swapped the old battery for this CR1620—it fired right up and saved me a trip to the dealership. The high capacity seems legit so far; my watch has been running accurately for a week without any power issues.

The CR1620 fits perfectly in my watch and calculator, and the lithium chemistry means I won't have to swap it out for years. It’s been running steady for two weeks now with zero drop-off, which is more than I can say for the last cheap cell I tried.

My car key fob has been finicky for months, and this little CR1620 finally woke it up again. It slipped right in and the range feels as good as new, so I'm set for a while.
