We've recently added some Kinoko IMR batteries to our lineup! Click on each battery for additional details and the results of our own in house testing..
IMR cells, also known as LiMnO2 (Lithium Manganese Dioxide), are cells built for a wide range of purposes, but mainly for high discharge rates. Compared to "normal" 2C discharge rate of lithium-ion - LiCoO2 cells, these cells are capable of up to 5-10C. Not all IMR cells are the same, but these cells are generally regarded as safer than their cobalt containing cousins. As such, (and combined with their high discharge rates) these are unprotected batteries. Batteries should always be charged when they are at or under 3.6V resting voltage. Batteries prefer shallow discharges, and do not suffer from a "memory" effect.
Lowest Discharge Voltage: 2.5V
Nominal Voltage: 3.7V
Peak Voltage: 4.2V
