Questions and answers
battery charger not shutting off when charged and boils water out. Mod # 750H3-12C S/N 217CS582884
The Ametek Deka PowerForce battery charger may not be shutting off when charged and is boiling water out due to one or more of the following reasons:
1. Equalize Mode Active – The charger may be in Equalize Mode, which applies a prolonged charge to balance the battery cells. This mode extends charging time and increases voltage, which can cause excessive gassing and water loss.
2. No Gas Inhibit Not Active – If the No Gas Inhibit function is not enabled, the charger may continue charging at a higher rate, leading to excessive electrolyte boiling.
3. Improper Battery Maintenance – If the battery has been stored for 30 days or a large volume of water was added recently, the charger may be compensating, leading to overcharging.
4. Faulty Charger Settings – The charger may not be set up correctly, and its Auto Equalize by Cycle function may be triggering frequent equalization cycles, causing overcharging.
5. Defective Charger or Battery – A failure in the charger’s voltage regulation or a faulty battery with imbalanced cells could cause continuous charging beyond the required level.
To resolve this, check the charger settings, verify if Equalize Mode is needed, and ensure the battery is properly maintained. If the issue persists, inspect the charger and battery for faults.
