A battery desulphator restores (at least partially) the battery’s ability to hold a charge by reversing sulphation. This is done by producing high current pulses between the terminals to break down the sulphate crystals on the plates. Pulse conditioning shifts the crystals and dissolves them back into the electrolyte without overheating the battery, as a constant high voltage would do and which could potentially lead to explosion.
Which batteries are candidates for a battery desulphator?
Batteries that can benefit from desulphation are:
- Older batteries that are operating well below their optimum level
- Those that have sat unused for a long time, e.g. in planes, boats, old cars and home power systems with underused battery banks - standing for long periods can cause heavy sulphation
- Those that will not accept normal charging
Symptoms of sulphation include high internal resistance and low current supply. If the battery is in a clear case or has been taken apart a white coating may be visible on the plates.
The following won’t be helped by a battery desulphator:
- Loss of lead material on plates
- Plates that are physically bent as a result of overcharging or temperature extremes
A battery desulphator could bring new life back to your old batteries. If you’d like to discuss using a battery desulphator or battery regeneration with us, please give us a call and we’ll do our best to assist.
