Ansmann CR2025 Lithium Battery

Picked up a three-pack of these CR2025s for my car key fob and they work perfectly—no more dim signals when I'm ten feet away. Voltage seems stable right out of the package.

Was tired of replacing my key fob battery every few months, but this CR2025 has been going strong for nearly a year now without any drop in performance. The lithium chemistry really does make a difference in longevity.

Popped one into my garage door remote and it’s working like the day I bought it—no drop-off in signal strength even from across the driveway. The 2025 size fit perfectly in the slot, and the lithium chemistry feels solid for the price.
