Attention: These IMR cells have much lower internal resistance than regular Li-Ion 3.7V cells and they may end up with a higher ending voltage when charged in some chargers. 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. They should never be discharged below 2.75 volts or cycle life/performance will be reduced.
Please read Lithium battery safety information before charging/using lithium batteries.
