MAINTAINING MULTIPLE BATTERIES
BatteryMINDer DS24041-AA-S5 maintenance charger-desulfator can maintain two 24-volt batteries
simultaneously, providing each battery is fully operational (no dead-dying cells), free of sulfate and
meeting the minimum full charge “rested” voltage of 2.13volts / cell, after being fully desulfated.
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. 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.
Test each cell of 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 2.13volts / 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”
of 2.13 volts / cell.
ALWAYS test each individual battery to be certain it is healthy and free of sulfate before attempting to
charge or maintain them, either as a single battery or in sets.
Audio Authority and VDC Electronics, Inc. do not make, supply, or recommend any type of wire harness
to connect individual batteries for the purpose of charging them in groups, due to the many battery
terminal sizes and configurations that exist. See diagram below for the most common multiple battery
configurations.
