Acebeam ARC18650H-250A IMR High Drain Li-Ion rechargeable battery

IMPORTANT NOTE:

• 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 versions of the WF-139 charger).
• Please check the voltage of your 18650 IMR battery right out of the charger with a Multimeter to see if they are above 4.20V when fully charged with your charger.
• These batteries should never be discharged below 2.5 volts or the life cycle and performance will be reduced. Overcharging above 4.25V may shorten life/cycles. Batteries that read above 4.5 volts may be damaged and we recommend to discontinue use of the charger. DO NOT use the charger if it is overcharging IMR cells.
• For best results and battery life expectancy, we highly recommend using a Smart / Intelligent Charger for charging all your Li-Ion type batteries for best battery life.

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
• Always remove battery from charger when fully charged
