What happens if you overcharge a battery?

Capacity Loss: Prolonged overcharging can degrade the battery's capacity and performance over time, reducing its ability to hold a charge and deliver energy efficiently. Electrolyte Decomposition: Overcharging may cause electrolyte breakdown and the formation of gases, leading to pressure buildup and damage to the battery's internal components.

Can a laptop battery be overcharged?

Yes, overcharging a laptop battery is possible. Most modern laptops are equipped with circuits that prevent overcharging and will stop charging the battery once it reaches 100%. However, older laptops or faulty chargers may not have this protection, which can lead to overcharging if left connected for extended periods.
