help Energizer Ultimate Lithium AA FAQ
Are Energizer Ultimate Lithium AA batteries rechargeable?
No. Energizer Ultimate Lithium AA batteries are primary disposable lithium batteries, not rechargeable lithium-ion cells. They are designed for long life in devices like cameras, flashlights, sensors, and outdoor gear.
What chemistry do Energizer Ultimate Lithium AA batteries use?
They use lithium iron disulfide chemistry, often written as LiFeS2. That chemistry is different from the lithium-ion packs found in phones, laptops, and power banks.
Why do hikers and photographers like Energizer Ultimate Lithium AA cells?
They are lightweight, have strong shelf life, and perform better than alkaline batteries in cold conditions. That makes them useful for GPS units, headlamps, trail cameras, and camera flashes.
Can I mix Energizer Ultimate Lithium AA with alkaline AA batteries?
No. You should not mix battery chemistries or mix old and new cells in the same device. Devices that take two or more AA batteries work best when all cells are the same type and age.
