Best 9V Rechargeable Battery For Smoke Detector

To charge my rechargeable 9V batters. I can charge two at a time this is the best.

Been looking for a 9V recharger for a while that wasn't expensive. I saw that energizer has rechargeable 9v batteries now, but the store didn't carry their recharge station... how bizarre. I don't recall even being able to find one online... Lol, Watson holding it down! They got you covered and for a lower cost!

For the price of two brand name alkaline 9V batteries you can buy one rechargeable one. The math is clear. I also find it handy to use a fully charged 9V battery for an electronics project or a device that requires 9V. The electronics (but not attached servos) of an Arduino project can be powered with this type of battery. The Watson 9V charger charges two batteries simultaneously.

This is the second Nest thermostat I have purchased along with a Nest Protect smoke and CD detector. I moved my original Nest to replace an upstairs old thermostat when the new 3rd gen Nest came out. The Nest does everything advertised and more. I highly recommend any of the Nest products.

I have been using these Rayovac 9V batteries in our smoke detectors for many years. They never corrode and they keep charge a very long time.

[This review was collected as part of a promotion.] We use these 9V in the smoke detectors, in our resident gate remoter, the Alkaline 9V can last a long time, so I don't need to change the battery frequently. I always stock up on these 9V batteries, and Alkaline brand sells at a reasonable price compared to similar brands. We use other models of Alkaline batteries in our home too, we like that these batteries lasts longer and cost less.

[This review was collected as part of a promotion.] I an using the Rayovac 9V Fusion batteries in our smoke detectors. They have lasted great with no leakage. I feel confident using Rayovac batteries in our smoke detectors to help keep my family safe.

Until these, I had never come across rechargeable 9V batteries. It's a great way to cut down on wasteful disposables.
