I was servicing my 1994 E320 and noticed the battery was purchased in March 1998, yikes!!!!! 8 years is incredible, it's a Interstate MT-93 so I am replacing it with the same thing. It still works fine but my kids drive it and it has to be ready to die.

Mine's 7 years old, and an "official" MB-labeled battery from the dealer.

Of course, having the battery in the trunk on the 400E probably extends its life due to less heat to put up with.

On my 95 E420 it lasted 7+ years and was the original Mercedes battery. This being my first MB I was nervous when one day I pulled up to a stop sign on a hill, and did sort of a slow, rolling stop, then hit the gas. Well, several lights on the dash came on, I believe one being the SRS, and I thought oh no what now!. A couple of weeks later it was slow to crank so I took it in for a check and sure enough battery was on last legs. pretty good though vs other cars I have had where battery maybe lasts 2-3 years.

Batterys on all our Benzes last a LONG time. Can't remember the last time I bought one.

Which is amazing in itself.
I've always figured with all the "power-everything" we have nowadays, batterylife would be shortened.
Got 6 years out of my original battery.
We'll see how long the replacement ( M-B ) will last.
