quality product

This battery has a different casing than a standard one. It comes in a plastic case, I am not sure why, but it seems more durable than a typical 9 volt battery. I trust Energizer makes quality products and I am expecting this rechargeable to last a long time.

Quality that works

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-effe...

Great product

I got these batteries for my smoke detectors and i love that fact that they can be recharged. This helps me save money because they are very long lasting even before recharging them. I completely love and trust this brand. Thanks

Re-Charged!

I charged the Energizer Rechargeable 9V Battery and put it in my Carlo Robelli guitar. So far it's outlasted any other battery I've used. But after the first recharge, it seems to actually have more power, if that's possible. It's been in my guitar longer this time and it's still going strong! Finally a good rechargeable battery!

works great

I have always been a fan of Energizer batteries. And I am also a fan of rechargeable batteries for saving money. Paired together this is a great battery to own. I love that it comes charged and ready to go right out of the package. I was able to open the package and insert it right in the car remote for my son and it was ready to go! Super convenient.

Works OK

I have a 16 hr charger that charges aa, aaa & 9v just right I think. Only have had this battery a couple weeks - so its on its first charge in a hand held laser thermometer that normally only needs a replacement battery because the battery dies from old age. From what I've read, they seem to hold their charge in smoke detectors for over a year.. Hope for that life here. Its very low milliamps don't expect to be happy with this battery in some high drain situations.

Works as described

This battery actually lasted pretty long and recharges quick. I dont have to spend money on buying new batteries for now since I can recharge this one. I feel like this one lasts longer than the ones ive used before. I would recommend it.

Only kind I use.

Energizers rechargeable batteries are the only kind I use, they’re long lasting batteries and nothing more then being able to charge them and reusing. They will forever be the only batteries I will be buy being worth the money.

Very nice to have a 9V that recharges.

Very nice to have a 9V that recharges. It's so nice to not have to continue to buy 9V batteries. I would definitely encourage others to purchase this battery. This battery is reliable and rechargable.

Thin and effective!

Best invention ever for 9V batteries! Fast recharge and good steady power output. I got tired of wasting my money buying expensive 9V batteries for our house smoke alarms. These are good. So far, the charge last more than 6 months and it takes just 3 hours to fully charge them again. I am saving a lot of money using these rechargeable batteries._x000D_
Highly satisfied and would recommend.
