  • – Do not over-discharge/overcharge
  • – When the battery is out of power ( resting voltage ~3.6V ) recharge it as soon as possible. Leaving Li-Ion batteries in discharged state will incur irreversible damage ( capacity / cycle loss )
  • – Do not short circuit ( will release tremendous current )
  • – Do not dispose of in fire.
 
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 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.
