Failure to test a “rested” (see pg. 9) battery will
cause false readings. Be certain to read and
understand all safety related instructions (pages 3
to 7) before proceeding further.
2.
Measure battery’s voltage, without any load
attached. If the voltage is less than 24.8 volts
(Typically 50% of charge) the battery may be too
heavily sulfated to be fully recoverable. If voltage
is 24.8-V or higher full recovery can be expected,
given sufficient time (average 1-2 weeks for batter-
ies that are heavily sulfated).
3.
Connect the BatteryMINDer to the battery.
Select type of battery.
4.
Charge battery to its maximum level. Press
Maintenance-Float (select Battery type) button, if
it does not go into this mode automatically. Allow
battery to remain for a minimum of 72 hours
before retesting. If improvement 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 sul-
fate will require several weeks or longer to
be fully dissolved. Be patient and you will be
rewarded with a “sulfate-free” battery.
