3.6V-3200mAh-LG-GBMH1-18650 Battery

LG18650MH1 Battery–(LGGBMH11865 3.6V )

The LG 18650 MH1 battery – LGGBMH11865 battery comes up with a nominal capacity of 3200mAh, the voltage of 3.6V .

The LG MH1 is a rechargeable, li-ion battery with 500+ charge cycles, making it a great value even among other 18650 batteries. INR (lithium nickel manganese) chemistry offers a superior 3,200mAh capacity compared to most IMR (lithium manganese) cells, while retaining a maximum discharge current of 10A. The flat top terminal design is great for use in creating battery packs.

LG MH1 INR 18650 3200mAh 3.67V High-Drain 10A Lithium Ion (Li-ion) Unprotected Flat Top Battery

The LG MH1 is a solid 18650 battery. Measuring in at 3200mAh and 10A, it is not considered a high-drain battery. It is however, a high-capacity battery with a fairly good maximum continuous discharge rating. SO This is an absolutely excellent cell for anyone seeking high performance 18650 cells.

Performance Specification

4.1.1 Standard Charge

Unless otherwise specified, “Standard Charge” shall consist of charging at constant current of 1,425mA. The cell shall then be charged at constant voltage of 4.2V while tapering the charge current. Chargingshall be terminated when the charging current has tapered to 50mA. For test purposes, charging shall be performed at 25ºC ± 2ºC

4.1.2 Standard Discharge

“Standard Discharge” shall consist of discharging at a constant current of 570mA to 2.5V. Discharging is to be performed at 25 ºC ± 2 ºC unless otherwise noted (such as capacity versus temperature).

4.1.3 Fast Charge / discharge condition

Cells shall be charged at constant current of 1,000mA to 4.2V with end current of 100mA. Cells shall be discharged at constant current of 6,000mA to 2.75V. Cells are to rest 5 minutes after charge and 5 minutes after discharge.
