Just got these Energizer 2032 batteries and wow, they're like little energy ninjas for all my small devices!

First off, the 6-pack is perfect - not too many that they'll expire before use, but enough to keep my key fobs, remotes, and even my grandma's hearing aid battery tester happy.

The temperature range claim is no joke. Left one in my car during both a heatwave and a snowstorm (oops) and it still worked perfectly in my garage door opener.

Child-resistant packaging is great since my toddler thinks everything is food. Though I may have needed the instructions to open it myself the first time...

Only downside? They work so well I keep forgetting where I stashed all my backup batteries!
