Review: These 3.7 are a mm longer than the 3.6. - I have a significant alarm system for my house and they go in the window and door sensors. The original 14250 (3.6v) batteries would go out every few years and I purchased these rechargeable ones. I took the battery clip in the device off, expanded with tweezers and these fit and work perfectly although they are a mm or less taller. They charged in an hour or less and I’ll chime in later for how long they last. Btw, I purchased 5 regular ones and they died in a year.

### ⭐⭐⭐⭐⭐ Worth every penny

Great product as described

### ⭐⭐⭐⭐ Charged Right Up
*by J***E on July 16, 2025*

I am always nervous when I purchase rechargeable batteries. There are many things that can go wrong resulting in damage to people of products. When I popped these in the charger, they charged right up. I haven't used them often as I purchased them for items I use very sporadically so I can't attest to their longevity. That's the ONLY reason I'm giving this four stars instead of five. I don't like when people post a five star review for a product they haven't yet used it its entirety. Those aren’t helpful in my opinion.
