98 e320 battery dies after sitting

Hello- I have a 1998 Mercedes e320. The battery dies if the car isn't driven for 3+days. The battery is newer. Has anybody had this problem?

Exactly how old is your "newer" battery?

I replaced the battery less than a year ago because of the same problem.

People have had similar problems, but I don't recall reading about a specific W210 with this issue.

One of your consumers is taking power all of the time and probably needs to be replaced. You can connect an amp meter to the battery and monitor the parasitic loss, then start pulling fuses. Once you find a fuse that reduces the loss, find what modules it powers.

You may have a battery drain somewhere, pull one fuse at a time until the drain goes away.

And don't forget to pull the seat to check the battery cables are on tight.
