Great key fob battery

This battery worked great in my car key fob. It is long lasting, reliable, and keeps the remote operating fully. Installation was easy. I would buy this again.

Energizer is always our go to! We bought this battery for a sign in my son’s room years ago and we have not had to replace the battery at all! They are affordable for lasting so long.

My go to brand when I need any of the odds and ends batteries. They work well and keep the power lasting for quite some time before needing to be replaced.

Can’t Beat an Energizer
on September 16, 2026

Each Energizer battery I use continues to last and make a difference in how well our units operate. This was used in a FOB and was a direct replacement. I always select Energizer for FOB’s as they come packaged the best (for child safety), last the longest in use, and are the best quality made.

It works well and has last for a few months now. It also has the color coating for child proof if its put in the mouth you can tell. It will turn blue or leave blue residue

The battery lasts a long time!! I bought it for my office; I’ve had it for about four months and it’s still going strong despite heavy use - incredible

Great product for AirTags. I use this product all the time and it never lets me down. I constantly feel Ike I can rely on this and the power is great and lasts awhile.
