Review on 5-Year Warranty AG3-20 Pack LR41 Battery - SURPOWER by John Kahsar

Bought 20 SurpPower LR41 cells. They dont last long, neither have shelf Life. Package states expiration date of Dec 27, 2025, and none of them are usable.I replaced the cell this evening, after device did not worked. Had to reopen the device to verify the cell. I measured the voltage across terminals and it read 0.65V. Assumed that this one may be a bad one, so checked other cells, hoping to find one that read close to 1.5V. Since i purchased 20 cell pack, i opened and checked 12 cells, and voltage measured between 0.5 and 0.7V.
