Storm 0 Posted March 5, 2005 If my battery is low / flat can I leave the battery in the car, connect a charger and then run electrical systems in the car? I dont mean start it just run for example the stereo? Quote Share this post Link to post Share on other sites
Banana Man 0 Posted March 5, 2005 yeah you should be able to I haven't tried it myself but if you have a charger with boost/start function then that should produce enough to run small output stuff like the radio and windows Quote Share this post Link to post Share on other sites
exturbo2003 0 Posted March 6, 2005 all you can run is wat is rated at less then the charger so if its a 4 amp charger the ignition on will be about 2 amps so not a lot can be run like that. Quote Share this post Link to post Share on other sites
Storm 0 Posted March 6, 2005 The charger has 12volts and 20amp rms written on the front and is a big old box (absaar). Is it right to think its a meaty old thing? Quote Share this post Link to post Share on other sites
