MAINTAINING MULTIPLE BATTERIES
BatteryMINDer 12248 maintenance charger Desulfators 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
sulfate and meeting the minimum full charge “rested” (see pg.
9) voltage of 2.13 volts / cell, after being fully desulfated. Press
the Maintenance - Float charge button immediately to ensure
BatteryMINDer is in the proper mode for maintenance charging-
desulfating, 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 sulfation) before
maintaining them in multiples. Only healthy, fully desulfated
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 accurate, 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 desulfate it until you reach a
“Rested*” voltage of 2.13 volts / cell.
Attempting to desulfate more than one (1) battery at a time will
yield very poor results, as the strongest (healthiest) and not the
weakest (most sulfated) battery will receive the majority of the
desulfation pulse energy. Exception is when two batteries are
identical and have been used in parallel or series with each other
during their entire life.
