Precautions
Battery and charging:
Charging is only allowed at 0°C~45°C, and discharging is only allowed at -20°C~60°C. The battery must be kept dry. It is strictly prohibited to put the battery in acidic or alkaline liquid. Rain must be avoided, and it shall be kept away from fire, heat and high temperature environment. It is strictly prohibited to reverse the battery’s positive and negative poles or damage them, plug in the battery or let it suffer from short circuit. Please use the original special charger when charging. The charging must not last more than 6 hours, and the charging current does not exceed 2A. When not in use for a long time, please keep the battery in a cool and dry place, and charge it for five hours every month. Users must follow the instructions when charging, otherwise they will be at their own risk. Attention shall be paid to the type of battery to which the charger is compatible and the applicable voltage, and mixing is strictly prohibited. When charging, it shall be placed in a ventilated environment. It is strictly prohibited to charge in a residential building and in an enclosed space or in a hot environment. When charging, insert the battery first, and then supply the mains power; when fully charged, cut off the mains power first, and then unplug the battery connector. When the green light is on, the power shall be cut off in time. It is forbidden to connect the charger to the AC power supply without load for a long time without charging. During the charging process, if the indicator light is abnormal, a peculiar smell occurs, or the charger case is overheating, stop charging immediately and repair or replace the charger. During the use and storage of the charger, be careful not to let foreign matter enter, especially avoid inflow of water or other liquids, so as to avoid short circuit inside the charger.
The charger should not be carried with the vehicle. If it is necessary to carry it, it shall be placed in the tool box after shock absorption treatment. Do not disassemble or replace the accessories in the charger by yourself.
