Battery won't hold charge 300E
I have a 1990 300E didn't start sit for a few days over thanks giving, I live in alaska and it's about 3 degrees here . My engine won't even turn over when key is turned , when I go to jump it I have to jump it for about 20 mins before it actually has enough juice to start ! Any idea what this could be?
I have just had my head gaskets and radiator replaced !
Pretty please help!

Sounds like it was over a few days... seems like it should be pretty simple to just get the battery tested though.

Yes. In other cars, I have had the battery drain overnight when I accidentally left the interior lights switched on. A battery check is cheap - in fact, I've always gotten mine free.
