  • What buyers say about Energizer Ultimate Lithium AA Batteries

    The higher the initial purchase price of these batteries, the less expensive they will be in the long run.

    For applications where changing a battery is a nightmare, the performance benefit can be huge. These batteries sport several unusual features that can make them better-suited for your applications than other batteries.

    If you have a clock hung in the air or a remote receiver mounted inside a crammed wall, it will take a lot of time and money to change the battery, but with the Ultimate Li-ion you can do it in less than an hour.

    These are some of the best battery packs you can buy for your digital camera, laptop, tablet, gaming device, or any other high-drain device.

    They have about a 8 year shelf life, but I can't come up with a reason for the price gap between alkaline batteries and drawing electronics.

    Common Questions


    Is it possible to use these batteries in regular items such as, lighted peppermills, smoke detectors, clocks, flashlights?


    They are not economical in low-drain appliances such as TV remotes, clocks, etc., because ordinary alkaline batteries can last just as long at a fraction of the cost.


    What is the best battery for long lifespan?


    I bought AA instead of AAA and use these in Trail Cameras which I use to take three pics in a set and have set for 5 Megapixels.


    Are these batteries packed "loose" or are they in factory sealed packs?


    My order was received in a factory-sealed package.


    I had a long life battery that came with the remote and it lasted 3 years, can you use the energizer AA lithium 9x batteries in a TV remote?


    It's a waste of money to use ordinary alkaline batteries in low-drain devices, which will last just as long as the batteries that come with the TV remotes.


    Is this a Li-IO or a Lithium-IO battery? To know if it is, need to declare the shipping company.


    It is a Lithium metal battery.
