I have been debating buying some reusable batteries and finally grabbed the Energizer Recharge 9V. My kids are always going through batteries with their toys and electronics. We charge the 9V battery overnight when needed and it lasts all day. Very easy to charge and works great!

I love to use products made from recycled products and I love bunnies too!

The price was kind of high, but worth it to not have to buy batteries all the time. I've been purchasing rechargeable batteries for years! Save your money! I just wish they were ALL still in stores like they used to be.

So I have written reviews about a lot of things, but a battery is among the hardest to write about. I do know that my experience with Engerizer has been very favorable and I think their batteries last longer than many of the competitors. I put this battery in my smoke detector so I clearly trust it!

I absolutely love Energizer Rechargeable batteries!! I have heard about these batteries and this is the first time ever using them aND I am completely sold on them!! A couple of my daughters toys take 9v batteries and it's so awesome to be able to take the battery out and charge it and put it back in instead of throwing the battery away and buying another!! Definitely a money saver that's for sure!!

So I really only have one device that takes a 9 volt battery. It is a dog training tool and it is a low battery drain device. This is literally the last 9-volt I will ever have to buy. It also charges quickly which is a plus because I have little patience, and we use the device frequently. Will definitely continue to use.

I had a tens unit I needed recharged to it's an Energizer battery regharging unit with a 9V. It works great!

This battery charges up fast, last a very long time, and is super convenient that you aren't constantly buying a new one. It was charged some when we recieved it but after a few days of use we had to fully charge it. We are on day 7 and it is still going strong! Definitely recommend them.

As a musician, I use a lot of 9 volt batteries on a regular basis for tuners, guitars, peddles, etc. I've been looking for a reliable rechargeable 9 volt, and I've finally found one with Energizer. The battery lasts long and is something I can count on when performing.Charging the battery does not take a long time, as is easy to do._x000D_

My only complaint is the charger has to be purchased separately. However, overall, this is a great cost saver at zero cost to performance levels. I...

I've been using this in my fire alarm, I love that it rechargeable so I don't have to keep buying more batteries. It's been going strong now for over 3 weeks. I check my alarm once a week to make sure it's still working. It's a great battery an I defently recommend using
