Our take on the Energizer Ultimate L91 AA 3000mAh 1.5V High Energy 5A Lithium Primary (LiFeS2) Button Top Batteries

Energizer Ultimate Lithium AA cells use lithium iron-disulfide chemistry to deliver a steady 1.5V and a rated 3000mAh. Energizer claims up to eight times the runtime of standard alkaline AA cells, plus a 20-year shelf life and operation from -40°F to 140°F. They weigh about 0.5 oz each and handle 3A continuous and 5A pulse draws, so they suit high-drain devices like cameras, flashes, game controllers and trail cams. Against rechargeable NiMH cells they cost more per use and cannot be recharged, but they hold charge for years and keep working in cold that drains alkalines. Buyers rate them 5 out of 5 across 106 ratings.

Questions and answers

How do these compare with alkaline AA batteries?
Energizer rates them up to eight times longer in most devices, with a 20-year shelf life instead of roughly 10 years for alkaline. They cost more per cell but need fewer changes in high-drain gear.
Can these batteries be recharged?
No. They are primary lithium cells and are meant to be used once and recycled. For repeated use, NiMH rechargeables are the alternative.
Do they work in cold weather?
Yes. They are rated from -40°F to 140°F, so they keep working in freezing conditions that weaken alkaline cells.
What devices are they best for?
High-drain devices such as cameras, flashes, game controllers, trail cams and smoke detectors. They also suit gear stored for long periods.
Are they safe for all AA devices?
They are standard AA size at 1.5V, so they fit most AA compartments. Check that your device accepts lithium cells, since some manufacturers specify alkaline only.
What is the maximum current they deliver?
3A continuous and 5A pulse. That covers most consumer devices but not high-power tools that need much more.
