It means it's 76°F. ;-)
Battery or alternator or something related. |
Oh snap. I'm hoping it's just low voltage in one of the batteries. It went away after driving awhile. The car sat a while with out being started so may have just got low.
|
I got the same message. I didnt drive it for about a week. Went shopping for stuff and no problems and no error messages. I think it's just that it sat or the rear battery will need replacing soon.
|
it will come back again. probably the aux battery in the engine compartment. gonna change mine soon.
|
I had to replace my aux battery under the hood when I got that warning.

So I fixed it by topping of the 6 cells with distilled water and slapping a trickle charger on it over night. Started up the next day and it didn't come on. Fyi each cell needed 2/3 cup water to top off. Make sure the drain tube is attached properly because when on the trickle charger some may boil over.

I wouldn't think it matters as the charger should feed both batteries simultaneously.

What kind of battery do you have in the car. Quite uncommon to have to add water to a battery these days.

No it does not work that way, there is an isolation relay that opens when the ignition is switched off (also at other times but that is not relevant here).

WTF? RTFM

I think you will still need a battery. But what do I a know anyway. ??:smash: |
Stock Mercedes battery made in Spain. I may have added a little too much water that's why a little drained out of the drain tube when it was on the charger. No return of the "workshop light" so far and the battery seems fine.

Not sure if this has been stated above as i CBF reading.
But check the SBC Aux battery under the hood, when thats about to fail that CHECK BATTERY warning light comes on, and if that batterys low, it will drain and cause errors on the 2nd battery in the boot. |
Where is it under the hood?

Wow a few of you guys must not wrench on your own rides, one of you is in Europe so that may be the reason why you have a water less battery. Here are a few pics of both of my stock batteries. Both require distilled water. I topped them both off, gave them full charges on the trickle charger and all is well now. No need to buy a battery quite yet.

FYI the main battery in the trunk took 3 days to be fully charged with the trickle charger. I don't like the idea of having the aux battery (water) right under the cabin filter. If it sulfates those fumes will be sucked right in to the cabin lol. Going to try and find an optima type that will fit there. |

Wow, did you read this thread? Or look at the photos? It's obvious from the photos that the stock batteries are not sealed and require water. Also I stated I topped both batteries off with water. Also I don't need new batteries since I fixed the problem with water and a trickle charger.
|
It might be a case of YMMV.
The big battery in the trunk of my car is more-or-less sealed. I think that it might (?) have caps under the big battery top decals, but it's obviously intended to be maintenance-free. Adding water, assuming it's possible, would make the battery in my car extremely ugly - with torn off decals. The last time I added water to a car battery would have been in the 1970s. |
WOW :rolf: Do you see the 6 white caps on top of the white battery? Those are the caps for the cells. They unscrew with a butter knife. Doesn't get an easier and you won't mess up any stickers :rolf: The aux battery just has one large strip cap that comes off with a small screwdriver.
