Hi, can someone please tell me the correct battery for my car, W210 E220CDi year 2000, had a new one fitted by garage about 12 months ago, Bosch s4 740a 80AH, if not used for 4-5 days is now flat, euro website says Bosch S4 900a 100AH is the battery for my car. Thanks

I have a 100...but that's not the problem you have. It shouldn't go flat after sitting for 4-5 days. You have a drain somewhere.

Hi, I had a drain on the hands free phone but that was turned off about 12 months ago, will get it back to the garage and let them check it out. Thanks for the help.
