1. We want to see if the color on the battery plate is abnormal and there is no sulfation phenomenon.
2. Check whether the plate is bent, broken, short-circuited, and other damage and falling off problems.
3. Pay attention to check whether the contact between the terminals on the battery is loose, firm, and corroded.
4. Check whether there is damage and leakage in the battery water tank, and whether the liquid level in the battery is abnormal.
5. The acid-resistant coating of the battery rack has been damaged and fallen off, etc.
6. The electrolyte liquefaction weight, terminal voltage and liquid temperature of the entire battery pack can be measured once every half a month to detect faults in time.
7. Check whether the electrolyte surface of the battery is kept on the plate above 10 to 20 mm. If the liquid level is lower than the standard, an appropriate amount of pure water should be added before charging. Of course, many maintenance-free batteries have become mainstream at present, but we also need to check regularly.
In short, we must also check the above points regularly. For safety reasons, we must treat it as a very important job when using Golf Cart.
