NOTE: These IMR cells have much lower internal resistance than regular Li-Ion 3.7V 
cells and may have a higher ending voltage when charged in certain chargers.

Please check the voltage of your 18500 IMR battery right out of the charger to see 
if it is above 4.20V when fully charged, (You can do this with a Multimeter.)

Overcharging above 4.25V may shorten life/cycles. Above 4.50V may even damage 
the battery. DO NOT use the charger if it is overcharging IMR cells.

Other Caution Notes:
- 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. We do not recommend unprotected batteries in 
  devices that they're not recommended to be used in, use at your own risk.
