VERY FLAT NEGLECTED BATTERIES:
equipment and inspect the battery before connecting the charger for a recovery attempt.
The charger's TURBO recovery mode cannot engage if it senses that the battery is still connected to a circuit which effectively
offers a lower electrical resistance than the battery on its own. However, if the deep-discharged battery is not removed for recovery, neither
battery nor vehicle or equipment electronics will be damaged. Pay particularly close attention to the following A battery left

deep-discharged for an extended period may develop permanent damage in one or more cells. Such batteries may heat up excessively
during high current charging.
Monitor the battery temperature during the first hour, then hourly there-after. Check for unusual signs, such as bubbling or leaking
electrolyte, heightened activity in one cell compared to others, or hissing sounds. If at any time the battery is uncomfortably hot to touch or
you notice any unusual signs, DISCONNECT THE CHARGER IMMEDIATELY.

during CHARGE mode.
The ampmatic™ current control program now delivers pulses of current to equalise
the individual cells within the battery and optimizes charge level.

Charging should complete within the minimum charge time set during STEP 3, but if
the battery requires further charging the program will extend OPTIMIZE mode up to a
maximum of 1/2 the charge time the battery remained in STEP 6.
NOTE: Charge time is usually extended if there is higher than expected current draw by
connected circuitry or battery health is less than optimal.
TIP: If the battery under charge was in a low voltage or suphated state, for the most
effective charge and test results disconnect the battery from the vehicle circuitry and
then charge.
For safety reasons there is an overall charge time limit of 72 hours for

The TEST will be interrupted if LED #8 (red) lights. A significant problem exists if the
battery is unable to retain sufficient charge during this voltage retention test. Consult
the table above to match TEST LED indication to an estimated state of charge
percentage (SOC%).
More information is provided in the section "NOTES ON TEST RESULTS".
ON
Float voltage setting: 13.6V nominal at 20°C (68°F) The float voltage is inversely
regulated according to ambient temperature; i.e., voltage is increased at lower

temperature, decreased at higher temperature.
7
Adjustment: -0.004V / cell / °C above or below 20°C (68°F).

STD maintenance mode consists of 30 minute float charge periods followed by and
alternating with 30 minute 'rest' periods, during which there is no charge delivered.
TEST
This "50% duty cycle" prevents loss of electrolyte in sealed batteries and minimizes
gradual loss of water from the electrolyte in batteries with filler caps, and thereby
contributes significantly to optimizing the service life of irregularly or seasonally used
batteries.
During "float charge" a continuous LOW CURRENT PULSE IS DELIVERED TO PREVENT
SULFATION, further extending battery power and life.
If the Milenco senses the battery has lost charge the program will revert back to
CHARGE step.
If the battery is deeply discharged (and possibly sulfated), remove from the vehicle or
