1. Look. Appearance: full drum, leaking, date of manufacture. The filled drum lacks water, the leaked lacks acid, and the long-term storage will cause vulcanization.
2. Ask. The power of the motor, the intensity of riding, the habit of charging. The high power of the motor softens, the riding is very soft, and it is easy to vulcanize if it is not charged in time.
3. Test. Broken grid, short circuit, and plate aging.
