CHARGING A FILLER CAP LEAD ACID BATTERY
A. Carefully remove all filler caps from your battery.
B. Check the water-liquid electrolyte level. If the level is low or has ever
been below top of plates, severe lead plate sulfation has taken place.
Significant recharge/reconditioning time is needed to restore these
plates to a condition where the battery may be expected to function
normally.
C. 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 instructions.
D. 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.
E. If the BatteryMINDer battery condition LED lights ( YELLOW) within
72 hours (single battery) or no balls float in one or more cells, your
battery may be too far gone to be fully desulfated. Reconnect battery
to your BatteryMINDer. Allow battery 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 table) 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 the battery. Continue
this process until the SG or voltage readings no longer increase.
TESTING WITH A HOT/
COLD CALIBRATED
HYDROMETER TESTER
Read the tester instructions carefully for
most accurate readings.
A. When using the tester the first time
or after a long period of non-use,
fill the tester with the battery fluid
and let it sit for 1/2 hour or longer.
This will soak the balls in order to
give you more accurate readings.
Failure to do so will give you false
readings indicating a battery that
may not be in as good a condition
as you may have thought.
B. After inserting the tester in a cell,
gently tap the tester several times
