The Sony 18650 VTC4 is a 2100mAh, 30A LiMn Battery and it is one of the best batteries for Mechanical MODs / Rebuildable Atomizer / sub-ohm user up to 90 Watts.
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.
This Battery is commonly used with the personal vaporizers and other devices which use 18650 Batteries such as flash lights, external battery packs for Laptops, Portable Powerbank chargers and devices such as Kangertech KBOX 40W Mod / E-Cigarette Device, Kanger Subox Mini Starter Kit, SmokTech Fury, Cloupor Mods, Evic variable Voltage Devices, Hitman 18650 Machanical Mod & VaporFlask up to 60 Watts requiring a High Drain 18650 battery.
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 such as the one at Nitecore UM20 Fast Intelligent USB Powered Li-ion / IMR LiMn Battery 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 a charger if it is overcharging IMR cells. For best results and battery life expectancy, we highly recommend using an Intelligent Charger.
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.
