MAINTAINING MULTIPLE BATTERIES
BatteryMINDer 36271 or 48021 Battery Maintainer-Desulfators can be used
to maintain up to eight 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
Glossary of Terms) voltage of 2.13 volts / 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 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 batteries are identical and have been used in parallel or
series with each other during their entire life.
