I have a 2007 E320 Blue Tech with 48,000 miles. When should I expect to replace the battery(s)?

I am new and don't know much....but teachable

Thanks!

Chuck,
My 1998 E320 original battery lasted until Dec 2005. 7 years for a battery isn't bad in my opinion. It would have lasted longer if the previous owners had actually kept her filled with water.

Do yourself a favor:
1. Don't worry.. you have a few years left.
2. Find out where the battery is.
3. Properly figure out how to check and maintain the water level in that large batter.
4. When the battery does finally go... replace it with a MB battery. It costs a bit more but will last for another 7+ years.

Good luck.
