Happy New Year all. For ages, I have been having an issue with my stop/start battery (the one in the boot). I've had the new one fitted for over a year. All was fine for the first few weeks. Then I started getting a message on the dash saying "Low battery, please charge " or something like that. The message comes up in as little as two days without driving the car. It's been back to the garage. Who then charge the battery, and do a 'drop test'. Then they tell me, there is nothing wrong with the battery. Is the rear hatch powered by this battery? Because the rear hatch lid opens very slowly and stops halfway open.
Please advise me. Thanks, Dave

Here is a post I added a while back
I had a lot of problems with Low battery warning. Even after Ctek charging it was still coming up with this. Changed both batteries last year but it soon came back & was driving me mad. The car was in the main not used much & doing short journeys, not the best conditions for a healthy battery, but Ctek should have kept it up. I also have an F type which was taken off the road at the end of October till the beginning of May & had a Ctek on constantly. No problems, started first time & stop/start worked from the off. A couple of weeks ago I put the Range Rover into an Auto electrician who diagnosed a parasitic drain. He had it for 4 days until he tracked down the fault. Obviously he was not working on it full time as he was checking something then had to let the car go to sleep to see if that was the fault or not, then do the same again. Since I got it back it has not been on Ctek, no warning messages & stop/start is working as it should. (Hope I have not jinxed it by saying its fine Smile Sad ( So dont change the battery, but get an Auto electrician to look at it, not the main dealer as they will just sub contract the work but add their cut. That is unless its still under warranty, but when I initially asked them about it they said drive it more so they are clueless. Hope this helps Thumbs Up Range Rover Sport (gone): Mercedes S63 AMG Coupe: 992 Porsche Carrera 4S: Range Rover Fifty P400e
