Called today and it seems they said its 2 years replacement no prorated anything...
Car won't hold charge under load...I leave the door open for 10mins and car won't start. Its getting 14v while on, so alternator is fine.
I charge the battery and it holds 12.50v disconnected, but as soon as its back in the car, drive for 5-10 miles and its dead 5mins with door open.
You can tell it has a weak output when starting the car too even when charged.
Last time I ever buy a MB Battery...didn't even last a year. Ordering a John Deere Group size 49 dry cell Tractor battery tomorrow
