MAINTAINING MULTIPLE BATTERIES
BatteryMINDer 24041 maintenance charger
Desulphators can be used to
maintain
up to
three 24-volt batteries at a time, providing each
battery is fully operational (no dead-dying cells),
free of sulphate and meeting the minimum full
charge “rested” (see pg. 9) voltage of 2.13 volts
/ cell, after being fully desulphated. Press the
Maintenance - Float charge button immediately to
ensure BatteryMINDer is in the proper mode for
maintenance charging-desulphating, immediately
after making proper connection to the batteries.
ALL batteries Must be properly tested to ensure
they are in good condition (no dead-dying cells or
excessive sulphation) before maintaining them in
multiples. Only healthy, fully desulphated batteries
should ever be MAINTAINED in sets of 2 or more.
Test each cell of All filler cap batteries using an
accurate, temperature compensated hydrometer.
Test sealed (no filler caps) batteries using an accu-
rate, DIGITAL type ONLY, voltmeter. The Minimum
voltage Must not be less than 2.1 volts / cell after
fully charging battery and letting it “Rest*” for 12
hours minimum, before testing. If battery voltage
is less than 2.1 / cell you must first desulphate it
until you reach a “Rested*” voltage of 2.13 volts /
cell.
Attempting to desulphate more than one (1) bat-
tery at a time will yield very poor results, as the
strongest (healthiest) and not the weakest (most
sulphated) battery will receive the majority of the
desulphation pulse energy. Exception is when two
batteries are identical and have been used in paral-
lel or series with each other during their entire life.
Never mix batteries of different type construction
/ chemistry, or condition (old with new). ALWAYS
test each individual battery to be certain it is
