the battery on my r129 goes flat after standing for a week(i dont use the car as often as i should i know) with everything off the drain on the battery is 250 ma is this reasonable? i cannot reduce the drain significantly by removing any single fuse.I have checked my battery voltage its 12.19v which seems a little low and also the built in charge indicator window shows recharge could this be a faulty battery ? and what voltage should I expect after an over night charge ? has anyone any other suggestions? thanks mark

Hi, that battery drain at 250m/a is too high, its losing 1 amp every 4 hours over 6 days thats 36 amps.
The boot light could be staying on, leave the meter joined up and pull the fuses one by one and you should find it
