Failure to test “rested” (see pg. 9) batteries will
cause false readings. Be certain to read and
understand all safety related instructions (pages 3
to 7) before proceeding further.
2. Measure battery voltage, without any load
attached. If the voltage is less than 37.2 volts
(Typically 50% of charge) the battery may be too
heavily sulfated to be fully recoverable. If voltage
is 37.2-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 batteries.
4. Charge batteries to their maximum level. Allow
batteries 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.
