Keep-power IMR18650-3000 mAh 3.6 – 3.7V Li-Ion battery 20A (constant) 35A (pulse) developed for LEDs, electric car or hobby model creation etc. Specially designed for challenging usage like on e-cigarette steamer with controlled battery carrier in the sub-ohm range etc. Box contents: 2x “Keep-power” IMR 18650 with 3000 mAh, included. An original battery box included. Notes: charging a lithium-ion batteries requires a special charger that charges the batteries according to a special charge procedure. (CCCV = constant current, constant voltage.)The batteries must not be charged with a voltage of 4.35volts, otherwise, there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approximately 4.2 volts, as this significantly increases the life or number of charge cycles (possibly up to a doubling). Only li-ion battery chargers may be used for charging. However, the inexpensive chargers sometimes have the disadvantage that they do not switch off safely after the end of the charging process, but instead recharge the batteries with a small charging current, which can be dangerous. Furthermore, batteries do not belong in the household waste! Please dispose these as prescribed by law in the municipal collection points off or in the prescribed [usually green] containers of commerce.
