The charger requires a minimum battery voltage of 1.5 volts per battery (overall for two batteries 3
volts, for 4 batteries 6 volts for 8 batteries 12 volts and 18V for 72V). If the voltage is below these
values then the charger will not function (Charger will not detect batteries to begin charge.) If the
batteries have fallen to such a poor state they will have to be removed from the machine and charged
individually with an independent charger until the optimum voltage has been reached. This is best
performed at very low currents to ‘recover’ the batteries if sulphation has already started i.e. a ‘trickle’
charger. This can take several hours, possibly days. Careful monitoring of the rise of battery voltage
will indicate when recovery has been achieved.
