Failure to test a “rested” (see pg. 9) battery will
cause false readings. Be certain to read and
understand all safety related instructions (pages
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 sulphated 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 batteries that are heavily sulphated).
.
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
sulphate in a few days. Long established sul-
phate will require several weeks or longer to
be fully dissolved. Be patient and you will be
rewarded with a “sulphate-free” battery.
