I have a 2020 GLB250 and mine was saying "12V battery" on and off for a few weeks. I checked under the hood with a multimeter and my main battery did have a low voltage while the car was off. I replaced it a few weeks back. No more notification.
I had the same issue on my w213 - same warning every now and then until one day it just didn’t start. Replaced the battery and solved the issue.
I put an Optima Red Top in it when my tester showed it below 75% health, about a year ago.
IMO, the Optima Yellow top is your only option. It will last 5-10 Years.
Absolutely not true. I use an Optima battery, works great. Have for a few years now since my 2nd garbage oem battery went out. Or was it the 3rd?
Get the battery from the dealer. It lasts longer and has a 7 year warranty. The Optima Yellowtop died on me after 3 years.
I bought an Optima Red Top battery for my van, but the part store accidentally got me the one with top mount terminals only instead of top and side like I requested.
I bought a red top.. in like 3 weeks it wasn't taking a charge and it got returned. Never again
From my experiance with the optimal batteries you are better off with a Walmart battery and save money. I tried the optimal 2x. Both failed within a year. They were warranties but the replacements didn't last much longer.
Red Tops are sh* and have been for 10+ yrs at this point. \nThe last 3 or 4 I had didn't last 2yrs and I got warranty replacements, which also lasted 2yrs. For $300+ they are sh*.
