TecMate International Optimate MILENCO 10 Mode D'emploi page 4

The TEST will be interrupted if LED #6 (red) lights. A significant problem exists if the battery is unable to retain
sufficient charge during this voltage retention test. Read the section NOTES ON TEST RESULTS on reasons for poor test
results or how to test a battery that returns a good result but cannot deliver sufficient power once it is returned to service.
* FIRST TEST : If charge delivery was less than 12 hours, test extends until 24 hours has elapsed.
STEP 6 MAINTENANCE CHARGE: LED #5 / 6 steady on
For 30 minutes the circuit offers current to the battery within a safe 13.6V voltage limit whilst the result of the voltage
retention test is displayed. If LED #6 (red) indicated the VOLTAGE RETENTION TEST will be repeated. A steady LED #5
(green) indicate the 30 minute float charge maintenance periods follow and alternate wih the 30 minute REST (no
charging) periods until the battery is disconnected. The battery can draw current as required to support small loads and
counter self-discharge.
Maintaining a battery for extended periods:
The Milenco 10 will maintain a battery whos basic condition is
good, for months at a time. At least once every two weeks, check that the connections between the charger and battery
are secure, and, in the case of batteries with filler caps on each cell, disconnect the battery from the charger, check the
level of the electrolyte and if necessary, top up the cells (with distilled water, NOT acid), then reconnect. When
handling batteries or in their vicinity, always take care to observe the SAFETY WARNINGS above.
Charging time:
The time required for the Milenco 10 to complete a charge on a flat but otherwise undamaged battery
is roughly 1/4 of the battery's Ah rating, so a 40Ah battery should take no more than about 10 hours to progress to Step
5. Deep-discharged batteries may take significantly longer.
Notes on TEST results:
1. If the red LED #6 lights a significant problem exists. The red LED means that after being charged the battery's voltage
is not being sustained above 12.4V (roughly equal to 50% charge in a sealed AGM battery) or that despite recovery
attempts the battery was irrecoverable. This may be due to a defect in the battery itself, such as a short-circuited cell or
total sulphation, or, in the case of a battery still connected to the electrical system it supports, the red LED #6 may be
signalling a loss of current through deteriorated wiring or a degraded switch or contact, or in-circuit current-consuming
accessories. A sudden load such as vehicle headlights being switched on while the charger is connected can also cause
the battery voltage to dip significantly.
2. GOOD TEST RESULT, but the battery cannot deliver sufficient power: Permanent damage within the battery may be
causing excessive self discharge (caused by the battery itself, even a partly damaged battery may initially retain
sufficient power, but lose power faster than normal there-after). Disconnect the battery from the Milenco 10. After at
least 12 hours reconnect and observe if SAVE LED #3 lights, indicating the battery was unable to hold charge. If CHARGE
LED #4 lights the battery retained at least 12.4V.
