How to Deal with a Battery That No Longer Holds a Charge After Long-Term Use?

[McAubrey]

To address a battery that no longer holds a charge after prolonged use, the following methods can be employed: 1. Use a positive and negative pulse method to depolarize the battery by charging it, then fully discharging it, repeating this cycle three times to achieve a repair effect; 2. Add water to the battery for repair, ensuring that only deionized or purified water is used. Maintenance methods for batteries include: 1. Promptly recharge the battery when the ammeter indicates insufficient charge; 2. Adjust the density of the electrolyte according to different regions and seasons. The reasons a battery may not hold a charge include: 1. Severe sulfation of the plates; 2. Excessive impurities in a single cell of the battery; 3. Aging of the generator belt; 4. Internal short circuit in the battery.
