Review: Good, long lasting battery. Very specific size. - These work well. I have a Radon system in my basement which has a small monitoring device, and these are the batteries it requires. The last quite a while, so the capacity is good. They are not rechargeable.
Review: These fit my alarm sensor perfectly - I had purchased a different battery but same specs a year ago for this sensor. For some reason, when I placed them in I had to squeeze it in, it barely fit and did not make the low battery on the panel go away. After a delay in shipping and having to hear the constant low battery chirp for an extra day - these batteries were delivered and fit and worked perfectly - no squeezing.

### ⭐⭐⭐⭐⭐ These fit my alarm sensor perfectly

### ⭐ DO NOT BUY
*by A***R on April 11, 2026*

I would give these replacement batteries zero stars if I could. Bought them six months ago to have a spare set. Went to use two of them today, and they are dead. Tried the other two, they are also dead. Garbage. Too late to return now so they’re going in the recycle bin. Waste of money.
