The Energizer Ultimate Lithium is an amazing product. If you need a battery that you don't want to replace often, this is the thing.

Energizer® Ultimate Lithium™ Batteries Nothing outlasts Energizer® Ultimate Lithium™ AA batteries. The Energizer® Ultimate Lithium™ batteries are not only the #1 longest-lasting AA batteries…they are complete with leak resistance and performance in extreme temperatures (-40ºF to 140ºF or -40ºC to 60ºC).

The chemical reaction begins when the battery becomes part of an external circuit through which the electrons flow between electrodes. The lithium atoms release electrons to become positive ions (Li+); the manganese atoms gain them, thereby going from Mn4+ to Mn3+.

Lithium is the lightest, most active metal. When this powerful metal is paired with iron disulfide, this energy is available at a voltage suitable for 1.5 volt applications. Energizer® successfully produced the first commercially available “AA” size 1.5 volt lithium battery in 1989.

The true advantage of Energizer™ NiMH rechargeable batteries can be found in the cycle life (resuse after charging). AA, AAA up to 5 years usable life; C, D, 9V up to 3 years shelf life.

Safe, Stable Chemistry One of the most important advantages LiFePO4 has over other battery types is safety. LiFePO4 is the safest lithium battery type. It's the safest of any type, actually. Overall, LifePO4 batteries have the safest lithium chemistry.

Energizer's lithium batteries are the top-tier power source in the company's arsenal of products - we have sizes that work perfectly for a huge range of applications, including remote controls, cordless power tools, game controllers, heart monitors, outdoor security systems, and more.

Energizer makes different types of long-lasting batteries: High quality Energizer MAX Alkaline AA, AAA, C, D, and 9V; Energizer Ultimate Lithium batteries, which are the longest lasting AA, AAA and 9V batteries on the market; Energizer Recharge, that are the most powerful and stable Ni-MH rechargeable batteries; ...

Energizer® Ultimate Lithium™ AA and AAA last up to 20 years in storage, while our 9V lasts up to 10 years in storage. Energizer Recharge® AA, AAA, C, D, and 9V last charged up to 12 months in storage, with a battery life of up to 5 years under normal conditions for AA and AAA batteries.

No. Energizer lithium batteries are not designed to be recharged. 16.

Can lithium batteries be charged in an Energizer charger? No. Energizer lithium batteries are not designed to be recharged.

Performance: Energizer is known in the industry at the longest lasting AA battery but tests have shown that Rayovac batteries perform just as long as Energizer batteries. Price: In addition, price was an important factor. Customers are constantly looking for ways to save, but not at the expense of quality.
