Energizer Recharge Universal Rechargeable 9V Batteries, 1 Pack

Seems to hold a charge well. Good price.

This battery is a game-changer! 🚀 It's got a faster response time than the Duracell alkaline 9V I was using. I'll definitely be stocking up on these for my pinpointer. Works great for metal detecting! #Battery #Response #Pinpointer #Metaldetecting

Awesome!

I purchased 3 of these 9 volt rechargeable batteries as I use them in a a stun gun. When I bought alkaline, the battery would run out of power in a few weeks. So, since these can be recharged 100 times, I save money by charging them overnight. It takes about 7 hours. I used to use RayOvac but RayOvac is slightly larger and would barely fit into my stun gun (RayOvac also used to be sold on amazon.com). Energizer is regular size & fits just right with 8.4 volts (8.4Vcc) NIMH. Some rechargeables are just 7.4 volt, so be careful what you purchase. By the way, it has been increasing harder to find rechargeable 9 volt batteries in supermarkets (and I live in Seattle), so I turned to amazon.com, and found what I needed. They also seem to hold a charge longer then the RayOvacs. They are made in China for a company in St. Louis, Missouri. UPC # is 0 39800 00916 6.

Bought it to replace batter for sprinkler system. What else can I say but it works

el producto funciona adecuadamente, sin novedades

Don’t last long at all. Made me a buy a regular non rechargeable batteries for my guitars. Unless you like to charge them every time before use then don’t recommend

Every battery we use is rechargeable. Last 5 years or more and saves money in the long run. Highly recommend product.

I've had this in my smoke detector for the past year, and the voltage is still holding up well even though I haven't recharged it. So, although this battery doesn't state it's low-self-discharge, it appears to be. It may not be cost-effective (compared to alkalines) in a low-drain device like a smoke detector, but I know I can charge it up and it's like having a fresh battery always on hand. Plus, NiMH batteries won't leak and ruin your device, like alkalines can. This would be very cost-effective in something that uses more power, like a mic or remote for a RC toy.

I bought this product for my TENS machine which I use almost on a daily basis. I used to buy normal batteries for the TENS and ended up spending quite a lot on batteries weekly. The rechargeable Energizer has proved to be very economical.

Es una batería recargable que funciona. Hace lo que tiene que hacer. La carga es buena, no es extraordinaria pero tampoco es mala.

Does the job.
