2 Pack Energizer 9V Rechargeable Battery NH22NBP NiMH 8.4V- 175mAh,

[This review was collected as part of a promotion.] I ordered these batteries because of brand recognition and Energizer's product consistency. They did not fail. The battery is reliable and the charge seems to last at least as long as a standard 9v making the rechargeable a great buy.

[This review was collected as part of a promotion.] These are a great way to save money on having to buy new batteries all the time. We are using this for our smoke alarm. It lasts a very long time once charged and it will be nice to charge and reuse so we always have them working. It is easy to charge and we are looking forward to getting more.

[This review was collected as part of a promotion.] The is just great this makes my life so much easier. I like that it is a rechargeable battery. So that means I can charge it and use it again and again!!!! I love this and the pro about these is that is so easy to use.

[This review was collected as part of a promotion.] This is fantastic!! I never knew they made rechargable batteries. These are perfect for your smoke detectors. I never have to buy another battery after having these. I definitely recommend trying these batteries. They are definitely convienient to have around.

[This review was collected as part of a promotion.] It's was good while it lasted, . But the charge doesn't last long. We used it in our smoke alarm detector. It does charge fast though. Just wish the life lasted longer on the 9V battery. All together the product is good. I wouldnt recommend using it for long term items such as a smoke alarm.
