Maintenance type battery
Maintenance batteries have caps to access the chambers containing the plates and the electrolyte. For a battery to function correctly
and to ensure its working life, the level of the electrolyte must be kept up to the maximum mark inside the chambers. This is particularly
important before charging. When topping up it is virtually important that eye protection and rubber gloves are worn. It is necessary
to maintain the electrolyte levels with distilled water, never use tap water. When adjusted, the caps should remain off through out the
charging process.

Charging procedure

During the charging process the battery voltage must be continually monitored and the charging output current adjusted.
1. Adjust the 12V/24V positive cable so that it is connected to the thread pillar connection that is correct for the battery you will
charge.
Caution! Double check the polarity connection before proceeding. Incorrectly setting 24V for a 12V battery will result in
damage.
2. Connect the red positive cable (+) to the positive (+) terminal on your battery.
3. Connect the black negative lead (-) to the negative (-) terminal on your battery.
4. To begin to charge the battery, set the Charger/Starter switch (5) to Charger.
Set the MIN or BOOST switch (4) to MIN.
5.
Connect the charger to your mains supply and set the On/Off switch (3) to ON.
6.
7. Monitor the battery voltage with a suitable meter and when the battery voltage reaches 12V (or 24V), switch the MIN/BOOST
switch (4) to BOOST.
8. Continue to monitor the battery voltage as it charges and when the battery reaches a full charge, around 14V (or 27V), the input
current displayed on the ammeter will reduce to zero. At this point, switch off the charger.
9. Disconnect the mains supply prior to removing the charging leads from the battery.

Starting procedure

1. Connect the starter charger to the vehicle battery, ensuring the correct terminal polarity is maintained.
2. Connect the starter to the mains supply and turn on the starter.
Note: You will need an assistant to sit in the vehicle whilst you operate the starter facility.
Begin cranking the car at the same time as setting the Charger/Starter switch (5) to Starter for 3 seconds maximum. After
3.
each 3 seconds of cranking, you must allow a minimum of 120 seconds for the machine to cool before cranking for a further 3
seconds.
4. If after 5 start attempts, the vehicle has not started, you must wait for the machine to cool down, continuing with the start attempts
will raise the temperature of the cable and will result in damage to the machine and may cause the mains supply to trip.
