De-sulphation
The de-sulphation cycle on switch position 8 is marked in red because this is a very dangerous setting if you do not
know what you are doing. Before ever attempting to use this cycle you must clearly understand what it does and when
and how you would use it.
What causes sulphation? This can occur with infrequent use of the batteries, or if the batteries have been left
discharged so low that they will not accept a charge. This cycle is a very high voltage charge cycle designed to try to
break down the sulphated crust that is preventing the plates from taking a charge and thus allow the plates to clean up
and accept a charge once again.
