I am currently using this battery to operate my insulin pump. It seems to be working well so far. I get almost two weeks of battery life - and sometimes longer - so it's much better than the last brand I used.

The Energizer AA Lithium Batteries really hold up to their claims of being longer lasting. I haven't found another battery that lasts as long as these. Well worth the extra money to upgrade to lithium!

You know the joke going viral about how you know your husband will not cheat on you because of hobbies? Well mine likes to research batteries. Turns out this is the best battery you can buy. And it's true! Longest battery life.

I always use these batteries because they have the longest use life. I rarely have to replace them and they keep our controllers working and my kid happy! They are a bit pricey but worth buying and having in the house.

Love these batteries! They are reliable and last a long time which is definitely a plus, being that I don't have to change them very often. I have never had any issues with them!

The more the better! Lasts long enough to not remember the last time you had to change them out. With two boys batteries are a must for all the trucks and toys!

my go to batteries i LOVE the cute bunny and always refer to it as bunny batteries, these packs are helpful because how common that battery size is especially in cameras

Great batteries. This are a must have in my house. With kids and a new baby it seems everything needs batteries. Best price is to buy in a large package.

Now these batteries are one of the best ones I've tried. I use these batteries for toys and mini fans for my 9 month old. These batteries last a very long time. I have toys with these batteries from 2 yrs ago that still work.

These batteries are fantastic! Unfortunately you have to pay a premium because of how well they preform. I would recommend these though as they are reliable.
