Well good evening folks. I have just joined the forum. I have also just bought a 2007 Grand Voyager Executive. I have a Rover 75 which I love, mainly because it has never let me down. But it is getting a bit tired, also my wife and I are not getting any younger, and the Rover is quite low. That makes it not so easy to get in and out of. Right first question, I have just put a brand new battery in the rover. Now assuming it fits, then I would like to change it for the one in the Voyager. Can I just disconnect the voyager battery or will I need to keep power on the car. I am not so tuned in with all these cars with their computers, so don't want to find I have to drag it to a garage for reprogramming etc. All the best Madmax
