What might happen to an AGM battery if you charge it incorrectly?

Charging an AGM battery incorrectly may lead to overcharging, overheating, loss of capacity, shortened lifespan, and even safety hazards.

Explanation:

1. Overcharging: Applying a voltage higher than recommended can lead to overcharging, causing excessive heat, electrolyte loss, and damage to internal components.
2. Heat Buildup: Incorrect charging can generate excess heat, accelerating aging processes, and potentially causing the battery to bulge or leak.
3. Loss of Capacity: Improper charging, especially at high voltages, can result in irreversible damage to the battery’s internal structure, leading to a permanent loss of capacity.
4. Reduced Lifespan: Continuous incorrect charging accelerates wear and tear, significantly shortening the overall lifespan of the AGM battery.
5. Safety Hazards: In extreme cases, overcharging may generate gas and heat, leading to the risk of a sealed AGM battery leaking or even exploding.

To avoid these issues, always adhere to the manufacturer‘s charging recommendations, use a compatible charger, and follow proper charging procedures. Regularly monitor the battery during charging to ensure it stays within safe parameters. If you suspect incorrect charging has occurred, it’s advisable to assess the battery’s condition and, if necessary, seek professional assistance.
