Merc A Class?
Answers:
Sounds like you have either a dodgy battery or a drain on the electrics, take it a merc dealer so they can use the Star diagnostic system to find the fault, you didnt say how old the car is but if its in its warrenty ask if there is cany recalls on A classs batteries as if there is it will be covered and your bil a lot smaller
The battery has a weal cell, that wiill not hold a charge, or you have a short to ground drawing down the battery.
"my wifes a class battery"! STOP batering your wife. No wonder she is flat

take your merc to a garage for a free battery check, if you need a new battery buy one, but shop around first for best price.
