I bought this 6months ago. I am using it in my smoke alarm. It still is going strong . I'm glad I can put my family's safety in your hands.I have a smoke alarm on every floor of the house and my Energizer battery is in every one of them.

I like the ability to charge these without having to buy alkaline battery's.

I am using the battery for my smoke detector in my house. So far, so good. I really like the fact that it uses recycled batteries. This battery seems to be lasting a lot longer than other rechargeable batteries I have used in my smoke detector. I love that the battery can be charged hundreds of times. I will never have to buy a battery for my smoke detector again. Energizer is a great brand and they did not disappoint with this battery. It’s well made and works great!

I prefer rechargeable batteries because that means as long as I stay organized I’ll never be out of power on my battery items. This 9v battery will get so much use in flashlights and power tools. Less in the landfill and less trips to the store for me! I recommend everyone invest in these types of batteries because it saves so much hassle!

Rechargable batteries, what more can you ask for? I got these to put in my father's recliner. I bought a few so I can have one charging while one is being used. I feel these essentially end up paying for themselves! All while under a good brand name. I love these. And I feel great knowing dad will always have his chair.

Dislike because they only work for about 5-6 hours and then need a to be put on the charger

These batteries work pretty well....I put them in my grandkids toy airplane and even tho the charge lasted for hours, I wish it would've lasted longer. But it charged back up pretty quickly. Overall these are convenient to have on hand and you actually get to save a little money

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.

The rechargeable batteries are great you don’t have to worry about finding batteries you can recharge it and you’re good to go last for a really long time easy to use easy to plug into your charger to charge a rechargeable battery and great quality

great rechargeable 9volt battery. there are awesome to have around the house all off my smoker director ues the. so I always like to keep an few around to have them when I need a replacement. great value
