MXJO IMR 18500F 1100MAH 3.7V High Drain Flat Top Battery
Description
Safe chemistry MXJO IMR LiMN 3.7V rechargeable battery in 18500F size. These cells can handle high amperage and is safe to use in series / multi-cell applications. Can be charge with any LiIon battery charger with 4.2V output.
These IMR cells have much lower internal resistance than regular LiIon 3.7V cells and they may end up with a higher ending voltage when charged in certain chargers ( especially older version WF-139 charger ). Please check the voltage of them right out of the charger to see if they are above 4.20V when fully charged with your charger. Overcharging above 4.25V may shorten life/cycles. Above 4.50V may even pop them or making them leak. DO NOT use the charger if it seems to overcharge IMR cells.
