Preparation
Always check the condition of the cables and clamps before using the battery charger. Do not
use when damage is noticed!
1. Disconnect the battery from the vehicle before charging. To do this, first remove the
negative pole connection, and then proceed with the positive pole connection.
2. Clean the poles with a steel brush or sandpaper.
3. Open the filler caps and check the level of the battery acid. When necessary, add distilled
water (liquid level must be ± 1 cm below fill opening).
Note: battery acid is corrosive; avoid contact with skins or clothing. Any spills should be
washed off immediately with plenty of water. Consult a doctor when necessary.
4. Open all filler caps and leave them open during charging, unless the battery has special
safety features built-in (e.g. spark arrestor). Refer to the data sheet of the battery or
consult a specialist to find out.
5. Make sure the battery charger is not connected to the mains.
6. Connect the positive clamp of the battery charger (red) with the positive pole (+) of the
battery. Make sure the clamp is secured tight.
7. Connect the negative clamp of the battery charger (black) with the negative pole (-) of the
battery. Make sure the clamp is secured tight.
8. Select the desired output voltage. Make sure this setting matches with the specifications of
the connected battery!
9. Plug the battery charger into a suitable mains outlet.
5.
Operation
1. When all preparations are done (see §5), switch on the charger.
2. Set the MIN/BOOST switch to MIN for slow charging (low current, 7 A), set to BOOST for
fast charging (high current, 9 A).
3. The current meter indicates the charging current. The more the battery is charged, the less
current it will draw. When the current reaches 0 (zero) the charging process must be
stopped to prevent the increasing battery voltage level from destroying the battery.
Note: another way to determine the charge level of the battery is by measuring the density
of the acid using a density meter (see table below).
density = 1.285 g/ml
density = 1.21 g/ml
density = 1.16 g/ml
4. When the battery is fully charged, immediately switch off the charger. Overcharging will
destroy the battery.
