Battery vulcanization: A layer of large white hard crystals is formed on the surface of the negative plate inside the battery, which cannot be peeled off after charging, nor can it be converted into lead sulfate as an active material. This is called irreversible sulfation, or "vulcanization" for short.

Battery vulcanization: A layer of large white hard crystals is formed on the surface of the negative plate inside the battery, which cannot be peeled off after charging, nor can it be converted into lead sulfate as an active material. This is called irreversible sulfation, or "vulcanization" for short.

Reasons for vulcanization: 1. The battery is under-charged for a long time or not charged in time after being discharged. 2. Long-term excessive discharge or low current deep discharge. 3. Because the battery loses water or the electrolyte concentration is too high, the composition is not pure. 4. The external temperature changes sharply. The performance is: the battery runs out after being fully charged.
