Parameter Description: 1.Battery Packs (battery pack) :: 11.1v 2200mAh 2.Rating (discharge coefficient): 20C 3.Prolite (connector): JST / T-head 4.Dimensions (size): 105 * 32 * 18mm To ensure the battery to maintain the capacity level, it is recommended batteries and battery packs in -20 ~ 35 ℃, the storage battery at low humidity, non-corrosive gas conditions Avoid storage at high temperatures or high humidity, otherwise it will lead to battery leakage, rust and reduced capacity. May lead to long-term storage batteries and battery capacity decreases, and requires 1-3 charge / discharge cycles in order to achieve the maximum discharge capacity. Place three months after the battery needs charging and discharging cycle time. Warning: Do not allow the reverse charge, the battery should be connected correctly according to the polarity can not reverse. Do not allow short-circuit, otherwise it will lead to permanent damage. The battery can not use under extreme conditions, such as: extreme temperature, deep cycle, extreme overcharge and over discharge. Keep the battery stored in a cool dry place, if a large number of battery storage or shipping to save battery must first discharge voltage (3.7V to 3.9V). Do not solder directly to the battery (nickel was diverted. For customers turn nickel, please communicate with customer service). If the battery is noisy, high temperature, leakage and other anomalies, please stop using it immediately. Do not fire or attempt to disassemble the battery may burn or produce harmful substances. Not allowed to use half of the old batteries or new batteries with mixed use, or will cause over-discharge. Can not cut and remove the battery shell jacket pipe. Do not allow the battery into the water. Note: Before the battery should be charged. Use the appropriate charger. Avoid the use of sealed batteries, should provide appropriate ventilation, otherwise the battery may produce hydrogen in the presence of an ignition source conditions can cause an explosion. Do not attempt to separate or bear squeeze and collision battery pack could cause the battery to heat, sparks, alkaline electrolyte spill will damage the skin and eyes will corrode clothing. The battery should be away from the kids, if they are swallowed, immediately contact a doctor need treatment. When the battery is not in use, it should be removed from the device. When used after the first use of a new battery or a long-term storage, fully charged before use. When the battery is hot, do not touch until it cools down. Found that when the battery power should be used to turn off the device fall, in order to avoid over-discharge. When you unplug the battery pack, battery terminals should hold the line and not holding. After the battery if the battery is hot, before recharging it could be placed in a ventilated place away from direct sunlight to cool.
