Do not over-discharge/overcharge
Recharge empty batteries as soon as possible (resting voltage ~3.6V). 
Do not short circuit (will release tremendous current)
Do not dispose of in fire.
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 certain chargers. Please check the voltage of them right out of the charger to see if they are above 4.25v when fully charged. 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.
