MAINTAINING MULTIPLE BATTERIES
BatteryMINDer 12248-AA-S1 maintenance char-
ger Desulphators can be used to
maintain
up to
six (6) 12-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 Mode Only button immediately and
hold it for 3 seconds 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 mul-
tiples.
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 2.13 volts / cell after
fully charging battery and letting it “rest” for 12
hours minimum, before testing. If battery voltage
is less than 2.13 / cell you must first desulphate
it until you reach a “rested” (see pg. 9) voltage of
2.13 volts / cell.
Remember, you must desulphate each battery by
itself (one at a time) before maintaining them for
extended periods. Attempting to desulphate more
than one (1) battery 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.
