This product has been around for years and was one of my first most trusted brand for batteries. I haven't noticed any changes, unless I have, involving the shelf life of the battery, I'm just glad they're around when I need batteries for my battery operated electronics.

[This review was collected as part of a promotion.] These Lithium Energizer batteries work awesome! My son put them in his game controller and has yet to change the batteries. That was over a week ago. We go through a ton of batteries in this house. Yes we have chargeable batteries and also charging docks for controllers,however we are a gaming family so we use A LOT of batteries. These seem to work the best. HIGHLY RECOMMEND!!

[This review was collected as part of a promotion.] In my opinion, Energizer has always provided powerful and reliable batteries. So, I was excited to try Energizer Ultimate Lithium AA Batteries. I am using these to power my portable reading lamp. It has been almost a month and it is running as powerful as the day I installed them.

[This review was collected as part of a promotion.] These batteries definitely last a whole lot longer than normal. Keeps the remote running for awhile before having to switch it out and many other devices as well. Great to use in flashlights to keep them ready to go incase of emergency.

[This review was collected as part of a promotion.] The Energizer Ultimate Lithium AA Batteries (4 Pack), 1.5V Lithium Double A Batteries are perfect! It is just what I needed for my remote controls and other battery powered electronics in my house! Amazing.

[This review was collected as part of a promotion.] Energizer has always been my go to battery. I trust these batteries with any appliance I want to last the longest. I mostly grab a bigger box so that they are always something I have on hand. I will never switch brands.

[This review was collected as part of a promotion.] If I’m out shopping, and I need a battery, energizer is my go to. They have always been and will be my favorite battery. I ended up selecting these batteries recently because I needed some AAs. I knew these would be great and long lasting, and I’m not going to have to worry about changing them out in two months time like the value store brands.

[This review was collected as part of a promotion.] Was super excited to see and try these out and was super pleased with the results. Even in old incandescent flashlights, these batteries make a strong beam and last a long time. In a modern led lantern the amp up the brightness and clarity to a visible degree. Have left these in the car in the heat of the day with no problem so far. Interested to see what their performance is like in the full summer heat.

[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.] 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.
