Energizer Recharge Universal Rechargeable 9V Batteries, 1 Pack

that works great. arrived items on time, well package, quality brand, great value, longer life rechargeable, make that thing runs good, light weight, fits, appreciated, thank you.

These are used for a few things, nothing that uses a lot of power, so these work. If used regularly, they need recharged once a week or so.

Very nice to have a rechargeable 9volt battery. Works c very well. Fast mailing.

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.

Glad they still make these 9 Volt rechargeable batteries.

Use this on my yard sprinkler system to make sure it does not use power.

I expected 4 batteries as the advertising claimed. Didn't think there was a reason to check reviews. Apparently many others were fooled also. The excuse is yes that was a mistake, but you should have read the small print. Really? Integrity matters. Rather than allow it to continue, FIX THE MISTAKE! It is not on the package, which would cost thousands to correct, it is on the printed description, which would cost nothing to fix and would take 10 minutes to correct. I have bought my last energizer battery, or any battery for that matter, from Amazon. What is the next false advertising that I will get fooled by? I will buy my batteries at HARBOR FREIGHT where I can see what I am buying!

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

Love these batteries for my guitar and pedals.

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.

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.
