NiMH battery charger
Nickel-metal-hybride (NiMH) batteries have now become widely available. A typical one is the 120AAH, which has a capacity of 1.2 Ah in size AA (MNI500; LR6). This type does not lose more than 45% of its capacity through self-discharge over a period of 25 days at a temperature of 20 °C. Recommended fast charging instructtons are charging with a current of 0,3 C for not more than 2.5 hours, or until the cell voltage has risen to 1.49 V, or until the cell temperature rises above 40 "C.
