. Refill each cell with distilled water only to the
liquid level indicator found in each cell.
Before
proceeding further you must be thoroughly
familiar with the safety and operating instruc-
tions.
4. Recharge the battery with the BatteryMINDer
to ensure that it is slowly and completely charged
before you determine its condition. Allow battery
to “rest”* overnight for a minimum of 12 hours
before testing with a temperature compensated
hydrometer and/or digital type voltmeter only.
* “RESTED” = a battery that has been as fully
charged as possible, using a 3 stage charger
(model 24041) and left disconnected from
charger or any type load for a minimum of 12
hours.
5. If the BatteryMINDer battery condition LED
lights (
YELLOW
) within 72 hours (single battery)
or no balls float in one or more cells, your bat-
tery may be too far gone to be fully desulphated.
Reconnect battery to your BatteryMINDer and
press the Maintenance mode button. Allow battery
to remain in maintenance mode for a minimum
of 72 hours, before re-test. Use a hot/cold cali-
brated hydrometer tester for the most accurate
results** (see next page) if you see an increase in
the Specific Gravity (SG) or voltage indicating that
there is an improvement in the battery’s condition,
continue desulphating for an additional 72 hours
and retest the battery. Continue this process until
the SG or voltage readings no longer increase.
