Our take on the Energizer Industrial Lithium LN91 AA 3000mAh 1.5V High Energy 5A Lithium (LiFeS2) Button Top Batteries - 24 Pack

The Energizer Industrial Lithium LN91 is a AA lithium iron disulfide (LiFeS2) battery with a button top terminal and about 3,000mAh of capacity. It is built for long storage and demanding drains, with a claimed 25-year shelf life and a 100% leak-proof guarantee. It is a direct replacement for the Energizer Ultimate L91 AA and holds up better than alkaline cells in cold and high-drain devices. It suits buyers who want a bulk stash for cameras, flashlights, remotes and emergency kits rather than rechargeables.

Questions and answers

How is the LN91 different from the Energizer Ultimate L91?
It is the industrial version of the same lithium AA cell and is described as a direct replacement for the L91. Both use LiFeS2 chemistry with a button top.
Can these be recharged?
No. LiFeS2 lithium cells are single-use and must not be put in a charger. Use NiMH AAs if you want rechargeables.
How long can they sit in storage?
Energizer claims a 25-year shelf life, so they work well as stored spares in kits and drawers.
Will they fit standard AA devices?
They are standard AA size with a button top, so they fit most AA compartments. Very tight spring contacts can make insertion stiff.
Are they good in cold weather?
Yes. Lithium AAs keep their voltage better than alkaline in low temperatures, which suits outdoor and winter use.

A 24-pack of Energizer Industrial Lithium LN91 AA button top batteries.
