Failure to test a “rested” (see pg. 9) battery will cause false read-
ings. Be certain to read and understand all safety related instruc-
tions (pages to 7) before proceeding further.
2.
Measure battery’s voltage, without any load attached. If
the voltage is less than 12.6 volts (Typically 75% of charge) the
battery may be too heavily sulfated to be fully recoverable. If
voltage is 12.6-V or higher full recovery can be expected, given
sufficient time (average 1-2 weeks for batteries that are heavily
sulfated).
.
Connect the BatteryMINDer to the battery.
4.
Charge battery to its maximum level. Allow battery to
remain for a minimum of 72 hours before retesting. If improve-
ment is seen, continue until battery voltage reaches full capacity
level or no further increase is seen.
Note: Do not expect to completely eliminate sulfate in a
few days. Long established sulfate will require several
weeks or longer to be fully dissolved. Be patient and you
will be rewarded with a “sulfate-free” battery.
