Check 12V battery检查蓄电池

1. Check the appearance of the 12V battery1. 检查蓄电池外观

1 Check the 12V battery case for damage. Damage to the casing will cause the electrolyte to flow out, and the electrolyte that flows out will cause serious damage to the vehicle. Auto parts that are in contact with the electrolyte should be quickly treated with electrolyte diluent or soapy solution.检查蓄电池壳体是否损坏。壳体损坏会导致电解液流出，流出的电解液会对车辆造成严重损坏，应迅速用电解液稀释剂或肥皂液处理被电解液所接触的汽车零件。

2 Check the 12V battery terminals for damage. If the 12V battery terminals are damaged, good contact between the 12V battery terminals cannot be guaranteed. If the 12V battery terminals are not connected and tightened correctly, it may cause a fire in the circuit, which may lead to great electrical equipment malfunction or even damage, making it impossible to ensure the safe operation of the car.检查蓄电池接线端是否受损。如果蓄电池接线端损坏，将无法保证蓄电池接线端能良好接触。如果蓄电池接线端未正确连接和紧固，可能导致线路失火，并因此导致极大的电器设备功能故障甚至损毁，从而无法确保汽车安全运行。

Caution:注意：

♦

Before conducting a comprehensive inspection, be sure to visually inspect the 12V battery's external condition, connections, and whether its position is secure.在进行全面检测之前，务必通过目测检查蓄电池的外部状态、连接情况及位置是否固定。

♦

Failure to secure the 12V battery correctly may result in damage to it.如果未正确固定蓄电池，可能导致其损坏。

♦

Check whether the 12V battery is installed securely and tighten the nuts to the specified torque if necessary.检查蓄电池是否安装牢固，必要时以规定的扭矩要求紧固螺母。

2. Check the 12V battery2. 检查蓄电池

1 Check whether the 12V battery case and wiring harness are corroded or broken, and replace them if necessary.检查蓄电池壳体及线束是否腐蚀或断裂，必要时更换。

2 Shake the 12V battery harness to check if it is securely installed.晃动蓄电池线束，检查其是否安装牢固。

3 If the 12V battery positive wire harness is not tightened firmly, first disconnect the 12V battery negative wire harness, then tighten the 12V battery positive wire harness, then reinstall and tighten the 12V battery negative wire harness nut.若蓄电池正极线束未紧固牢固，则先将蓄电池负极线束断开，再紧固蓄电池正极线束，然后重新安装并紧固蓄电池负极线束螺母。

4 Disconnect the positive and negative 12V battery harnesses.断开蓄电池正负极线束。

5 Let sit for 10 minutes. Use tools to test the 12V battery.静置10分钟。使用工具对蓄电池进行测试。
