[This review was collected as part of a promotion.] I received energizer ultimate lithium batteries to try in a 4 pack. I love the energizer brand and the quality they offer. The batteries last a very long time and are easy as always to install in anything requiring batteries.

[This review was collected as part of a promotion.] What can I say. The most trusted name when it comes to batteries. I've been using Energizer batteries since I was a kid. Energizer batteries are extremely long lasting and affordable. Perfect for any product rhat requires batteries.

Bought the large package at Christmas because my regular brand wasn't available. They really came through for me. Grandkids would have been really disappointed with no power. I was impressed that the preformed as well as my usual brand with many of the same features. 

I needed these batteries more than a cup of coffee this morning because my smoke detector was yelling every other 60 seconds “Low battery” When you have kids and most of their toys need batteries, along with a smoke detector, you may need to have extra batteries on hand. These batteries are the best: long-lasting power, easy to find in every store, and available in all sizes.

[This review was collected as part of a promotion.] Honestly, I have always picked up batteries at the dollar store thinking "a battery is just a battery". Now I see the difference! These batteries were much stronger and stayed powerful when the "other" ones had slowed to barely working! These will be my go to batteries moving forward!

[This review was collected as part of a promotion.] The Energizer Ultimate Lithium batteries are great for my high performance/high demand electronics. With the kids being out of school we are really using all the electronics around the house much more than normal. Having a long lasting battery helps keep the kids doing what they want so I can get done what needs to be done. In my opinion, I feel these batteries last longer than other ones I've tried. The electronics that have the ultimate lithium batteries are changed noticeably less frequently than other batteries.

[This review was collected as part of a promotion.] I got this specifically for use in my handheld GPS and they work great. I’ve used alkaline batteries before but they are drained in no time. The recommend batteries for the GPS are lithium and these sure do they job. Had them in for awhile and they hold up great. I can’t attest how these would do in an application where alkaline batteries are recommended but if lithium is recommended these will do the job.

Batteries work great in all dividers from remote controls to children's toys. They last longer than most other battery brands I've used and personally will not use another brand for my devices if I have any control over my options. 10/10 would use again!
