Energizer Rechargeable 9 volt Battery, (NH22NBP)

[This review was collected as part of a promotion.] I have been using this battery in my smoke alarm. It seems to be working really well. I have not had to recharge it yet. So it seems to be holding the charge for a long time. I would recommend this battery to anyone looking for a rechargeable battery.

[This review was collected as part of a promotion.] 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!!

[This review was collected as part of a promotion.] 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.

[This review was collected as part of a promotion.] First of all I love the fact that i can feel very good about buying this battery because first of all it's made out of 4 precent recycled battery. Secondly I love how long it keeps charge after you have finished charging it even after using it for awhile, better then leading brands. I would highly recommend this battery to friends.
