3. 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 batteries with the BatteryMINDer
to ensure that they are slowly and completely
charged before you determine their condition.
Allow each battery to “rest”* overnight for a mini
-
mum of 12 hours before testing with a tempera-
ture compensated hydrometer and/or digital type
voltmeter only.
* “RESTED” = batteries that have been as
fully charged as possible, using a 3 stage
charger (model 36271) 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 or no balls float
in one or more cells, battery may be too far gone
to be fully desulfated. Reconnect battery to your
BatteryMINDer and press the Maintenance mode
button. Allow batteries to remain in maintenance
mode for a minimum of 72 hours, before re-test.
Use a hot/cold calibrated 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 desulfating for
an additional 72 hours and retest. Continue this
process until the SG or voltage readings no longer
increase.
