Additional Info:

NOTE: These IMR cells have a much lower internal resistance than regular LiIon 3.7V cells and they may end up with a higher voltage level when charged in certain chargers. Please check the voltage of your freshly charged 18650 IMR battery to see if it is above 4.20V when fully charged with your charger. Overcharging above 4.25V may shorten the life/cycles of your battery. Charging it above 4.50V may even damage it. DO NOT use a charger if it is overcharging IMR cells. 

Additional Warning:
- Do not over-discharge/overcharge
- Recharge empty batteries ( resting voltage ~3.6V ) 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.

Using unprotected batteries is not advised in devices that they are not recommended to be used in, use at your own risk. Do not use adapters with these batteries. They should never be discharged below 2.5 volts or the cycle life/performance will be reduced.

Warranty: Please refer to our Warranty page for details.
