Battery OEM FORD or OEM Mercedes

Everyone's suggesting things that might save you half a percent or so, but no one has pointed out that by driving at 80mph, you lose *around 30% more battery* than if you were doing 70mph over the same distance

Had the OEM battery until 2021 before it died. I think six years in the NE is pretty decent for an OEM battery. 78k miles on the truck so far. No issues with the starter or the new battery since replacement.

For my Mercedes sprinter I had the same battery in it for 10 years. I went and bought it at the dealership. Since the last one lasted 10 years. I shouldn’t have a problem with it.

In my car (2021 Mach E AWD with standard battery), the battery state of health the first time I checked it was around 94% at around 48,000 kilometers. I’m not sure how accurate the car’s data is because it seemed to drop a percentage or so immediately after a couple of OTA updates. It sat at around 92% until between 80,000 km and 113,000 km, but now it’s says 92.5% at 120,000 km. Again, I’m not entirely confident at how accurate the car’s information is, but my range is still about the same as when it was brand new. I think I’m past any danger of manufacturing defects, so I don’t have any reason to suspect that the battery won’t easily last a couple hundred of thousand kilometers more.

Kakabili ko lang ng Everest, so far no problems minus that one time na itinirik ako ng wala pang 2 months of ownership kasi defective yung battery. Common issue siya that happens around 6 months - 1 year, kaya ina-advice na palitan agad yung stock battery sa fecp na group, pero ang OA ng 2. months. Granted, napalitan naman agad battery for free pero ang hassle parin.

The Ford battery in my Fiesta is as old as car so 10 years but despite still being able to start car it would only charge to 50% of capacity

same issue with daily driver 2021 E63. In this case though, the car doesnt give me a warning as much as the Mercedes app on my phone - it alerts to low battery -even critically low, but when I get into the car it starts and there is no message.

Just bought a new G63, same issue!

I’ve had it 3.5 years and it just started doing the “Stop Vehicle Leave Engine Running” thing about a month ago.

Exactly the same issue I am currently facing with a month old GLC300. No resolution yet
