Important
Make sure the charger is OFF when you
connect the battery to it, or you might get sparks at
the battery terminals that could ignite the gases
inside the cells. Always connect the red positive (+)
terminal first.
Attention
NEVER connect the battery in parallel with
that of other vehicles, as this may cause a short
circuit or overheating of the battery.
