Efest purple IMR 18650 2100mah 38A (Pulse 60A) battery with flat top

Quick Overview

Efest Purple 18650 IMR 2100mAh Flat Top Battery - 38A
The Efest Purple 18650 IMR 2100mAh Flat Top 38A Battery is one of the best batteries for cloud chasing enthusiasts / sub-ohm users. These safe chemistry LiMN 3.7V rechargeable high drain batteries do not require a protection circuit and they also have a reduced risk of venting with flame or explosion. Not only are these the safest batteries available, they also perform better for a longer period of time. Can be charged with any Li-Ion battery charger with 4.2V output however, for best battery life we recommend charging with a Smart / Intelligent Charger.
Price is for one (1) battery.
IMPORTANT NOTE: These 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 versioins 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 an Intelligent Charger such as our Efest Bio Charger or LUC LCD Chargers for charging all your Li-Ion type batteries.

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
