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!

[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.

[This review was collected as part of a promotion.] I bought these a couple weeks ago. They are great batteries. These were bought to replace the ones we had. They last a long, long time and it’s the brand that my husband trusts for all his battery needs.

Long lasting power

[This review was collected as part of a promotion.] I put the Energizer Lithium battery in a light up alarm clock about 6 weeks ago. I’m using it at the sign in desk in my office. A few folks come in very early, before all the lights are on so it’s the perfect use for the clock and battery. The light and time display are nice and bright, just as bright as day one. I will continue to use this type of battery and get more!
