USING THE 12V BOOST FUNCTION
To operate BOOST, the charger must be connected to a 12V lead-acid
battery with the battery clamps connected. For optimal results, allow boost to
complete its 5-minute charge. After 300 seconds of boost the display will show
“000” and it should be possible to start the vehicle (whether FULL light is
illuminated or not). If unsuccessful when starting your vehicle, let the battery
rest for 15 minutes and try boost again. Most vehicles will start with one boost.
Do not use the boost function more than twice within a 24-hour period. If 2
boosts cannot successfully start your vehicle, have your battery replaced or
evaluated by a local battery supplier.
