Long lasting and great price

Great battery for the price. I use these in my guitars and they last forever. They’re pretty bullet proof! I usually get about 6 months of continuous use out of them before they start to die.

I like it because the battery lasts a long time, its performance is very good, the packaging is small and it is compatible with several toys, the price is cheap, it is worth buying.

So important to have

I always make sure I have a few on hand for smoke detectors. Packaging is fine and not horrible to open but lasts long times and I do not have to hear the chirp

Long lasting!

[This review was collected as part of a promotion.] I use a TENS unit for back pain. When I have a flare up, it’s not uncommon to kill a battery in a single day. I was very pleased that this battery lasted almost 4 full days before I had to change it. These will be my go to batteries for my TENS unit going forward.
I would recommend this to a friend!

The Best!

[This review was collected as part of a promotion.] The battery out performs any other 9V battery you will find on the market! For those of you that haven’t having to replace your fire alarm more than once a year, look no future. This battery exceeds expectation!
I would recommend this to a friend!

[This review was collected as part of a promotion.] You can always count on energizer to give you the best and long lasting batteries for your needs. Used this for my smoke detectors. Fit great and last a very long tome before replacing is needed. Definitely batteries you can rely on.
I would recommend this to a friend!
