Energizer - Rechargeable 9V Battery Power your world with these Energizer Recharge rechargeable AA/AAA batteries. Perfect for use in toys, digital cameras and handheld games, these eco-friendly batteries hold their charge

Best Buy is one of the few places that still carry the 9V rechargeables, and with the free shipping this makes this a great place to buy. I've gotten tons of usage out of my rechargeables (game controllers, stairway lights, etc)

I’ve been using rechargeable batteries in my smoke alarms for a long time from Energizer. It finally became time for new rechargeables and I stuck with Energizer. Can’t go wrong with the bunny lol. They just keep going...

These are great rechargeable batteries. They hold a charge well and can be recharged numerous times. I've been using them for years.

The batterie doesn't last too long, I used a brand called Tenergy , they are cheaper and they last twice longer, I'm a professional musician so I use them everyday and it's very clear the diffrence.....

it's recharge able but after you recharge the batteries doesn't last long.

These batteries charged nicely and hold for a long time. I'm glad I bought these for my smoke detectors instead of replacing batteries twice a year I just recharge over a day and keep my peace of mind

Came in useful when needed. Helped me out when I had to.

Saves money in the long run. Able to recharge when needed and no need to run out to buy new batteries just recharge and good to go.

I was spending too much money on batteries saw this rechargeable ones figure would it a try I was amazed haven’t bought batteries since then just charge them good to go no more throwing away batteries and buying new ones and wasting money.

Bought to go along with my charger that I use for rechargeable batteries for my Tens Unit. Already paid for itself by not purchasing disposable batteries!

Great to use for cordless microphones and wireless instruments.

Nice old fashion rechargeable 9 volts battery, just what I need since my old system cannot recharge the new lithium batteries. Will last for the next 10 years

Purchased for our sprinkler system backup power. Great product.

I'm hoping this battery can keep my small solar house light running for many years considering it's more expensive than the whole light fixture itself

It does a great job. Having a rechargeable battery around is great. I just hate now that it's harder to find them when I need them, making it much more impossible to use.

This battery really saves you, you use it and charge it.
