Battery OEM FORD or OEM Mercedes

I replaced the battery in my '16 F150 last year - I'd say it had a good run. Went with another OE battery since the original lasted so long.

This just happened to me last month on my 2017 C43 on the OEM battery. I guess five years is typical on these newer MB.

Even in the colder weather now, I'd be getting 400+ km on a full charge in my BEV (Mustang Mach e). But I only charge once a week (Fri night), to 80% to help with battery life; costs about $3 per week to get an extra 200-300km.

the only time it failed me was when the battery died after 100k miles.

Sodium ion has about half the volumetric and gravimetric energy density. Li will remain king in the EV space for a long time to come.

A friend of mine had a 2010 ( or 2009 ) Fusion Hybrid that needed a new battery, he went to the dealer and he was quoted over $8K. He then found $3K 'aftermarket' batteries and at the end he was able to find a shop that did the whole thing for under $2.5K.

I had the same problem. My car was brand new too but was sitting for a bit before it was sold to me. I brought it in to get charged a few times but the message was still coming up and I was definitely driving it enough. Eventually they just changed the battery under warranty.

The batteries Mercedes uses seem to be really poor quality. I have a daily class and it seems they are changing the battery every 1.5 years so far on average…

I've dealt with this issue on both of my newer AMG vehicles. My older ones never had this problem. From my understanding, this is caused by the new mbux system being a bit of a power hog. I eventually had to invest in a trickle charger, and I have to charge both of my AMGs 3-4 times per year. It gets worse as your battery gets toward the end of its lifespan.

Both of mine were defective. Ford replaced them.
