Benefits of Opening Cell Caps When Charging an Accumulator
Question
Give reasons why it is necessary to leave the caps of the cells open when charging an accumulator.
Answer
Ventilation and Gas Release
When a battery is charging, it generates hydrogen gas as a byproduct of the chemical reactions occurring within the cells. If the cell caps are left closed, this gas can build up, potentially causing pressure to increase inside the battery. Opening the cell caps allows for the safe release of hydrogen gas, preventing the battery from becoming over-pressurized and reducing the risk of explosion or leakage.
