Battery Duracell or OEM Mercedes

The best lead acid type of battery is a Duracell/East Penn hybrid/house AGM deep cell. These have thicker plates and are typically used for RVs and boats. They can tolerate deeper discharge and are less susceptible to damage (AGM). They sacrifice a little instantaneous current output, but that's not needed on an EV.

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

We’ve always had luck with Duracell in our cars.

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.

The replacement battery I bought was a Duracell from Sam’s Club. Fit and worked fine.

I’ve replaced several Duracell batteries recently that had been recently installed within the last few month. We’ve had good luck with power sonic, yusa, and first power.

Always like Duracell because I hate that damn bunny. But doesn't matter to me right now because my damn RMR is defective and drains the battery in 3 months.

Just bought a new G63, same issue!

I bought the battery last summer, drove the car around for about a month no problems.

I put the car away for autumn/winter.

Took it to auto parts store last night, checked in in the morning.

Employee brought it out, said it needed more time and put it back on "fast charger".

I come back 4hours later and they're telling me it exploded on the charger??

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