Roger Blassberg 0 Posted June 25, 2007 I drove the Corrado for the first time in 3 months this weekend, after having kept the battery charged every 2 weeks or so during its layoff. I came to drive it this morning and the battery was still alive but only just, not enough to turn the engine. So it's new battery time which is no surprise as it has been on the car for at least 5 years and has been a bit neglected over the last few months. My question is this; if I connect the battery leads to a charger and then disconnect/reconnect the old/new battery will anything on the car, such as the ECU, be damaged during the transition? The "method in this madness" is to keep the ECU energised throughout the process of battery-swapping, and thereby avoiding having to do a basic settings?

yalan 0 Posted June 25, 2007 you can buy memory savers which plug into the cigarette lighter socket which are designed just for this purpose. fairly sure halfords do them. Not sure I'd want to leave a charger plugged into a sytem without a battery in the loop. Quote Share this post Link to post Share on other sites
