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.
BATTERY CONTROLLER
This machine is fitted with a Battery Management System that monitors battery condition. A main
component of this is the Battery Controller Unit. If for any reason the battery controller circuit has been
disconnected, please ensure that the batteries are
fully recharged
before using the machine as this
enables the Battery Controller Unit to reset automatically.
Note; this requirement does not apply if the battery isolating handle (Anderson connector)
ONLY
has
been disconnected.
The Battery Controller Unit has been calibrated to function correctly with Niftylift factory fitted batteries.
If for any reason you suspect
any
of the batteries have been replaced with a non-factory fitted unit then
please contact the Niftylift Service Department on (44) 01908 857899, Fax: 01908 227460.
As machine performance will be severely affected.
TOPPING UP
The batteries installed on this machine are
Maintenance Free
, therefore
DO NOT REFILL
with
de-ionised water. Irreparable damage will occur.
