Save money on this 9V batt
July 25, 2019
I'm using this rechargeable 9V battery in the smoke detectors around the house, got tired of buying 9V batteries. It took almost 24 hours to charge it but that depends on your charger. No telling how long the charge last but so far so good. Buy a bunch and save yourself some money!

Using in my Smoke Detectors in the house

I had purchased the Tenergy brand earlier (D cell, AA, AAA) and all of them are very strong and good batteries, so I decided to replace the smoke detector batteries with the rechargeable Tenergy 9 volt batteries. They all are working great. I will recharge them when day light savings comes around.

I have a driveway alarm that was going thru a battery every month. Didn't seem to matter whether it was a generic battery or top of the line, 35 days was the longest any of them ever lasted. Started using these a few months ago and got 90 days out of it. Actually, it wasn't dead yet, but we had snow coming in and I figured with my luck that was when it would go dead so changed it before the storm. Once good weather gets here, I want to see just how long it will go before going dead.

I've tried many brands of rechargeable 9V batteries but none have done the job that these have done for me.
Saved alot of money using these

I purchased 2 batteries to use interchangeably in a cordless microphone back in March of 2011. Just replacing them now 3 years later. They were used every week during that time for about 10 hours a week.
