WARNING
Voltage Spikes
Modern vehicles with electronic management systems should not be jump started without “protected” jump starter leads and it is necessary to refer to the owner’s handbook for jump starting procedures for such vehicles.

When charging batteries, work in a well ventilated area – never in a closed room. Always turn the battery charger or ignition off before disconnecting a battery.
