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.
Reinstall the battery on its mount and secure the upper
bracket with the screw (1). Connect the terminals. Use
some grease on the fastening screws to improve
conductive capacity.
