capacity. The selections given on the range selection table are appropriate for starter
type batteries. A charge current of about half the charge current indicated for that Amp-
hour capacity should be OK for sealed deep cycle or trolling batteries.
3) Depress and release the "CHARGE" push-button.
4) If, and only if, charging an "MF" battery of one of the appropriate types described above,
depress and release the push-button next to the "MF" black battery symbol below the
"CHARGE" button. When the charger stops for whatever reason, the "MF" mode
selection wilI automatically re-set to "Non-MF" mode. This is for safety reasons. Thus it
is necessary to re-select the "MF" charge mode each time one starts to charge an "MF"
battery.
5) The charging current entering the battery can be read off the charging current LED panel
to the right of the "Charge" button, one Ampère per illuminated LED.
6) The 4 charging status LEDs below the charge current LED panel indicate how well
charged the battery is at any moment. This is not simply a question of the battery
voltage. The first "low battery" symbol indicates a battery with excessive resistance,
possibly deep-discharged or even sulphated, with the automatic high-voltage recovery
action engaged. The second symbol indicates a battery under constant current "rapid"
charge. The third symbol indicates that the voltage of the battery under charge has risen
to the control point appropriate for that type of battery ("MF" or other) according to the
selection of the "MF" charge button or not. At this point, the battery is about 75 %
saturated & sho uld normally be able to start the engine. However this MUST be
confirmed by conducting a load test. If you have time and wish to charge the battery
more thoroughly, the battery may be left connected for the remainder of the unelapsed
time. The charging mode will from now on be at a voltage limit of 13,8 Volts. Should the
current fall of it's own accord to 10 % or less of the selected charge current during the
remaining charge time, this is an indication that the battery is more than 90 % saturated,
and the fourth LED above the ‘MF’ battery" symbol will light.
7) ALWAYS RE-TEST THE BATTERY AFTER CHARGING TO CONFIRM IT IS IN GOOD
SHAPE. Remember that a "fully charged" battery is not necessarily able to start the
vehicle if internally damaged.
8) The LEDs indicati ng charge time elapsed and charge status achieved and "MF" charge
mode will continue to indicate until the battery or the AC input are disconnected or until
the battery is re -tested or re-charged so as to allow the operator to observe these
parameters even though absent at the time the charging terminated.
9) Switch off the AC mains switch before disconnecting the battery clamps.
RECOVERY OF DEEP-DISCHARGED OR SULPHATED BATTERIES
If the indicated actual charge current is less than the charge current selected according
to the range selection table, this is because the battery under charge has excessive
resistance to accepting the charge, probably due to deep-discharge or possible
sulphation. In such cases the BatteryMate will itself detect this and react automatically
by increasing the applied voltage as required to enter at least some current into the
battery initially. The maximum voltage is limited to 24 V. After a while the LED-ammeter
should gradually start to indicate an increasing current as the resistance is overcome,
until the indicated current and selected charge current correspond. Should the selected
