I've had it with Duracell's leaking batteries and replaced all my batteries with these So far, no leak and good performance does it for me!! Review: New batteries look great! - 16APR25 Of the four, 3 measured better than 850mAh and one a not too bad 822mAh (see photo). I used a 100mA charging and discharging rate. Using a RC3563 battery tester to measure resistance I found a nominal 150mΩ value. This is the lowest value I've ever seen in a 9V. I'm not sure whether, or not, the battery's internal circuitry will, non destructively, protect things in a short circuit situation. That's 60A!! ## Features - 850mAh High Capacity: Kratax 9v rechargeable batteries cycle life can reach 1000 times, 40% higher capacity than other brands of 600mAh lithium-ion battery, full charge voltage: 8.4V-8.7V, maximum output current: 2.3A, larger capacity and ultra long lasting.
