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 12.4 volts (Typically 50% of charge) the
battery may be too heavily sulphated to be fully recoverable. If
voltage is 12.4-V or higher full recovery can be expected, given
sufficient time (average 1-2 weeks for batteries that are heavily
sulphated).
3. Connect the BatteryMINDer to the 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.
