MB battery warranty?

This has been the year for batteries. We have an old Cadillac that we inherited which has eaten two batteries in the course of two years. Walmart exchanged them. Then my Ford ate it's 2 year old battery. Again, Walmart gave us a new one. Now, our Sprinter will not take a charge and reads only 6 volts.
MB replaced the chassis battery in 2018 under warranty when we purchased the coach. 2 years later, the battery refuses to hold a charge. What kind of warranty does MB have for their batteries? I couldn't find a date stamp on the battery core.
We picked up a new one at O'Riley Auto Parts which has a 3 year warranty. At least if it goes out we won't have to drive 50 miles each way to find out what MB won't cover.

Call your dealer. Second remember you disconnect your coach battery when not using. The connection is near the gas peddle. If you have a charger on the coach then you donít need to do this. The house charger well charge the coach with a separate connector, I donít remember the name. My 15 View needed a Battery last fall. I used a small solar in summer but that did not do enough.

MB Chassis Battery

More than likely, the real issue is a MB problem, as it more than likely is that something is Drawing Down the Chassis Battery. MB will see the Draw above 50ma and tell you sooty. I found that my manufacture wired the Radio & Camera Switcher (their stuff) off the wrong side of the ignition switch.

Bite the bullet get a good AGM battery. Have a the MH tested for how much draw is on the Chassis Battery 50 ma is max as per MB. If it is, have a good Car Stereo Shop look for Wiring issues as above, and correct. Then test again.

Coffee Drink is correct, to use the Chassis Disconnect, it is Great, but you should only unplug it after 10 minutes of Turning Off Engine and letting the MB computers finish itís checks and have a controlled shut-down. If you donít you run the risk of having the Check Engine light come on (as early as within 1-week of having it reset. It most likely will be a #87 relay code fault.

I learned all of the above the hard way.
