Review on High Performance EBL 8 Pack 1200MAh 1.5V AAA Lithium Non-Rechargeable Batteries - Ideal For High-Tech Devices With Constant Voltage by Randy Perry

You may be surprised, as I was, to learn that the best alkaline AAA cells have exactly the same capacity as these: 1200mah. Where lithium cells have the advantage, it turns out, is in long storage life and constant voltage that makes them ideal for emergency radios, for sensors in remote locations, and for applications where voltage stability is critical. A lot of alkaline powered devices stop working while there’s still plenty of energy left in the battery, but the voltage has dropped below acceptable levels.I measured these on my tester, and all showed full capacity, and all were within 0.02 volts of each other.
