1. Before installation, check whether the battery is damaged or leaking, and clean the surface of the battery with a dry cloth. If the battery case is broken or leaking, replace the battery immediately to avoid acid corrosion.
2. The battery should be installed upright and should not be inverted. The distance between adjacent batteries should be more than 2 mm. At the same time, it should be anti-vibration and anti-pressure. It should be installed firmly. It will not shake and rub against each other during use.
3. In order to ensure safe use, the battery case for installing the battery must have a vent hole of not less than 8 mm ventilation, and must not be blocked to prevent the gas generated by the battery from accumulating in the battery case.
4. Each battery should be connected in series, and the positive and negative polarities should be correct, and the connection point should be in good contact, and no spark should be generated.
5. Devices that are prone to sparking, such as electric door locks and fuse holders, should be isolated from the battery.
6. The battery is charged and shipped out. Usually, the user can directly load the car. For example, if the battery is left for a long time (more than 2 months), the battery should be recharged before use. Plug the charger into the battery box and connect the 220 volt AC. The charger turns green. After charging for 1 to 2 hours, you can stop charging.
