1. When batteries are used in groups, it is recommended to match the batteries first. Measure the batteries and make those with the same or similar open-circuit voltage as a group. It is recommended that the voltage difference of a single cell shall be a level.
2. After checking that the battey is normal, install it in a designated place (such as a battery rack).
3. Avoid installing batteries near heat sources (such as transformers).
4. Because batteries may generate flammable gases during storage, avoid installation near spark generating devices (such as fuses) during installation.
5. Before connecting, clean the battery terminals so that they appear metallic.
6. Be careful that the conductive material short-circuits the positive and negative terminals of the battery.
7. When using multiple batteries together, first make sure that the batteries are connected correctly, and then connect the batteries to the charger or load. In this case, the positive terminal of the battery should be connected to the positive terminal of the charger or load, and the negative terminal should be connected to the negative terminal. If the battery is connected to the charger incorrectly, the charger will be damaged.
8. Pay attention to the firm connection when wiring, but do not use too much force to avoid damaging the terminal and tighten it according to the recommended torque. Do not use excessive force on the terminal parts. Each connecting nut and bolt must be tightened.
