Had to buy a new battery as mine was dead this morning. Does anyone know if a number in these pics indicates the year of the old one? Looks like the original battery,
seven years old.
I believe the date code is on the terminal post. Says 08/11 which I think means 8th week of manufacture, 2011. They don't seem to last that long in a W212, the charging algorithm is probably worse in an effort to save gas. My W211 battery is still going strong, about 10.5 years old at this point. My w212 was used and the previous owner had already replaced the battery a couple years ago.
Yup, that's what my original look like. It was stamped the 36th week of 2010 which is about the build date of my 2011 model. I would be thrilled with a battery lasting 7 years. Sadly the FL heat eats them up. First one lasted 4.5 years (started going bad after 4 years and kept it on life support with supplemental charging for 6 more months) and its replacement is going bad at about 3 years of use.
Seem each manufacturer has their own data codes and European codes are quite different than US codes.
Still the stamp on terminal looks like no-codded manufactured data.
We had 1997 Varta battery lasting 13 years in our ML, where under the hood placement kept it hot all the time.
Couple of W210 owners reported 17 years on factory battery.
W212 has power recovery program, meaning the car runs on battery power during acceleration and then battery is getting boosting charge during braking.
Batteries don't like that kind of treatment and seems new batteries last much shorter than the those manufactured 20 years ago.

It's been mentioned in many other threads. The date on the post pretty much matches up to the date of the car when they're the OEM batteries.
You're always engaging in that same logical fallacy. Correlation does not imply causation. Because batteries don't last as long as they used to, they're not made as well as they used to be. Yet in the same post, you acknowledge that the charging algorithm used isn't good for the life of the battery.
I gave you short story and you wrote lengthy conclusion on it.
The truth is that I have never heard from W211 owner who would have battery more than 10 years old.
Than 20 years ago - Costco was selling batteries with 100 month warranty. The best they do now is 36.
How is that for facts?

Ok here's some new facts. My w211 has the original battery and it's over 10 years old at this point. Actually it's a little over 10, will be 11 in November. I checked the voltage on the dash, it's still in a good range.
Like I said, correlation does not imply causation. I don't really understand your point about the shorter warranties. As mentioned earlier, lots of places got rid of the prorated warranties due to the law suits regarding the pro-ration aspect of the warranty. Some thought that if you have a 7-8 year warranty, the battery should last that long or you should get a new one without any extra pay like most warranties. It also costs more to run those warranties. Walmart actually sells a battery that only has a 1 year warranty, starts at around $49. They're only in popular sizes and nothing in our size. Some people have bought them and are still running them. Does that mean they won't last much more than a year? Or does that mean that they don't have to deal with warranty returns after a year and can offer it at a lower price?

I just changed my battery last week. It was almost exactly 3 years old. The original that was changed out 3 years ago was in the car for 5 1/2 years and probably would have run longer but I had it changed as my MB service rep recommended doing so. It was bout $450 job.
My 3 years old MB battery started giving me some problems. I thought my starter is going out but at battery test it said voltage is too low for the test.
My problems were that sometimes the car acted like all battery power was drained ar start. Finally then last week drove to AutoZone and got a new battery for $199. Made a bid difference at starts.
Funny thing, if you call road side assistance and get them to send a truck out and replace your battery, the cost is less than what it cost to replace it at the dealer. I had mb road side come out last year to my house, they brought a new battery installed it and gave me a bill for $288. The truck was from the local dealer. I eventually got them to cover it under warranty. But if I had brought the car into the shop to have them replace the battery, it would've been close to $500.
So it's odd they charge nearly 1/2 as much to send a truck out to replace your battery.
And just for fun, I rechecked my battery, has a 45/07 stamp on the terminal which works out to the same week as when the car was released.
As for a weak battery, I would have taken it out and put it on a charger just in case the alternator isn't giving it a full charge. Then get it load tested before getting it replaced.
Advance Auto is probably the best deal on a battery, there's a 25% off code which you can find on retailmenot.com and their battery is $199 also but about $150 after the coupon code. They even claim to install it for free too.

AutoZone guy installed it for free for me and I kept the old one as the core charge was only $18. Just as if it would be another issue than the battery after all. But it seems the battery change helped the starts.
This is the Platinum H8-AGM battery (900 cold cranking amps) with 3-year warranty. It is not pro-rated warranty. If it fails within 3 years they replace it for free..
Advance Auto has the same specs on the H8 battery. Same 900 CCA, 3 year warranty and 160 minutes reserve capacity. Probably made by the same battery manufacturer.
