Time to change battery in my 2013 C250 and need advice
I have a C250, 2013. I think it's time to replace the battery. It's been 5+ yrs.
It's as simple as changing a toyota battery? Any think I should know?
What type of battery should I purchase?

My 2011 C300 battery died after its five year service. I bought the same exact battery from dealer and installed it myself. Straightforward, no need to reprogram anything. The battery is roughly $120.

^this, you must be from Europe, my dealer wanted 475$ for a battery.. It was a good battery which was a 2008 production and just started to get weak earlier this year so I replaced it before it completely died. I got a good deal on a Bosch battery for 200$ with 5 year warranty.

Initially I went to a local Autozone and priced a Duralast H7 AGM at $207.00 with the core return, but
just for kicks I stopped by the dealer and ended up buying from them at $165.00 for a Genuine Mercedes battery. Personally when it comes to anything electrical I go full Genuine.
Part # 000-982-32-08
I hope that helps.

Just replaced my 2011 C300 battery. Very straight forward and not difficult at all. There's a lower hold down bracket with 2 13 mm (I believe) bolts and that's it. Don't forget to keep the red 90 degree elbow for the vent tube.

I called Interstate battery wholesale in GA, for new one is $184.98, new but blemish is $59.88.
I' thinking of the blemish one. same exact but some scratches.
Do this car has a secondary battery?

$278.00 that’s crazy! It’s unfortunate with these dealers as it seems to really vary from dealer to dealer and state to state on what they charge. I fully expected to get a qoute around the same price but have no idea why it was so cheap?
I’d go with the blemish one.
Good luck.

I first noticed it on start ups, it didn't seem to start as strong as it use to. Then I left the headlights on with the car off for a minute and the car barely started, that day I drove straight to the part store to switch my battery. This was in cold weather.

About 30 minutes after calling, the clean-cut young feller showed up in a spotless MB van and installed the same Part # you show above.
Battery price was $193. Installation - including a check of the electoral system - included.
However, I did have to pay the sales tax.
Now the little Iridium coupe no longer must suffer the indignity of an age 6 1/2 battery.
It's all good,

My 2014 has the secondary battery in the trunk but no one here seems to know its function ... one guy thought it was for the 'Eco' mode instant restart but that seems unlikely as small as it is.
I've had good luck sourcing reasonably-priced batteries at Batteries Plus ... order online and pick up at the store just down the street from me. There are only 3 - 4 makers of batteries in the US, so whatever brand/label you see is going to come from one of those companies, including most car dealer's so-called "factory" batteries.

The secondary battery provides power to everything when the engine shuts off while in ECO moade.

Interesting ... so would cover the alternator output going to zero with the engine stopped ... but since ECO mode is limited to max of something like 30 secs, hard to see why the big battery couldn't power everything for that short period ...

the 2nd battery is for your eco mode indeed. If you have a weak 2nd battery the eco mode will never switch on and always stay yellow. I have a weak 2nd battery at the moment and my car never goes into eco mode.

It's to prevent voltage drop on engine restart in eco mode. Because all the consumers are up and running full speed, not like when you first start the car, including possibly the transmission aux pump and other things, the voltage in the system could drop below 10v on restart for a split second, which can cause issues in some control units. The aux battery is tied into the whole system to keep the voltage up on the restart and prevent any sort of issues.

They are separated by relays in the SAM normally, the aux battery can be connected or disconnected by the battery management system as needed to charge it or let it power the accessories. With the car off there should be no power coming to the leads going to the aux battery once the battery is removed, it's not wired straight to the main battery.
In the 205 and newer cars they've done away with the aux battery and are using a small capacitor for it's functions.
