sure, but its a lot slower ,unless you disconnect a cable from the running car while jumpers are still connected


Hook up the cables like normal and keep the running engine at around 1500-2000 RPM to spin the alternator faster. If you have a meter, hook it to the battery and you can watch the voltage drop as the non running car battery charges. It would run it at least a half hour. -- You can also remove the battery and take it somewhere that has a charger.
