Battery warning on dash, Is this early stages of needing to replace?
What's up everyone.
Been getting this error on the dash for a little while now.. less 2 weeks but close to it, - I have gotten this once or twice before in very cold weather but its now daily on the car these past near 2 weeks. I know on the carfax i never saw anything about battery replacement mabe a recharge but my W222 is a 2015 with 62.xxx miles and being in the north east with these low temps but im thinking im at the early stages of needing to replace the battery.
I see on Advanced auto I can get there platinum battery which I have in my Cayenne but the Advanced is 95AH compared to MB 105AH, 160 Reserve minutes compared to 200 MB, 900CCA compared to 950 MB but $Z250 compared to what I see MB is $500
we can rule out loose cables and connections but the photo i've never seen so I come to everyone here lol.

Well, I've seen two other battery warning messages in my W222, but only when the engine was off. And yes, both messages were ultimately solved with a new main battery.
Your message, on the other hand, is coming on while the engine is on. That leads me to believe it's not necessarily the battery itself that is failing, but something to do with the vehicle's charging system. I'm NOT a mechanic, so someone else can please chime in and save us here.
I'll be curious to learn the final conclusion.
Good luck!

Picking up a H9 tomorrow .. despite everything saying H8 I prefer to have the H9 - my current battery is 105AH and the H8 is 95AH so getting an H9 is 100Ah and to my OCD makes me feel better knowing I got it lol.
And I bought the Noco Battery Charger i posted before so ill charge the H9 overnight and install it in the morning.
the AUX battery I replaced in March 2023 with an OEM MB

Here's my 2 cents.
www.rockauto.com for your battery needs.
Replaced both batteries in my 2019 S560 already around the 60K mark.
These were the closest to factory specs I could find. Both are Bosch batteries.
