Safe chemistry LiMN 3.7V rechargeable battery is now available in 18650 size. These cells can handle high amperage and is safe to use in series / multi-cell applications. Can be charge with any LiIon battery charger with 4.2V output.
Nominal Voltage : 3.7V
Capacity : 1600mAH
Lowest Discharge Voltage : 2.50V
Standard Charge : CC/CV ( max. charging rate 4.5A )
Cycle Life : > 500 cycles
Max. continuous discharge rate : 15C
- Do not over-discharge/overcharge
- Recharge empty batteries ( resting voltage ~3.6V ) as soon as possible. Leaving LiIon 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 LiIon 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.
Due to new postal regulations, we are not allowed to ship these
batteries outside of the United States, including APO and FPO
addresses. We will remove these batteries from any international or
restricted orders and ship the rest of the items. We apologize for
