The Sony 18650 VTC4 2000mAh 30A Battery is one of the best batteries for the Mechanical APV / MOD, Rebuildable Atomizer and sub-ohm user (lowest recommended resistance is 0.2ohm).
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 includes 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.
