Is 5 1/2 years old time to change the Varta battery? Engine tries to turn over every
I thought maybe the computer was a little off so I got out of the car turned everything off shut the doors locked the doors unlocked the doors then got back in and tried it and it started no problem.
Yesterday I stopped for 10 minutes to check out a condo and came back to my car and it would not start it was doing the same thing all over again every 1 second trying to turn over. But I manage to jump it with one of those tiny little hand held power boosters that I have It is the size of a small paperback book.
Anyway I'm going to replace the battery today from auto zone as I noticed that the date code on it says 23rd week of 2013 which makes it 5 and a 1/2 years old. I have never had any car battery ever last me more than 3 years down here in Florida but was unsure about the age of life expectancy for Varta batteries.
Anyway I have 2 questions for all of you 1st question is is this normal life expectancy for these batteries? Also I cannot find my battery anywhere at Sam's club , Costco, or Walmart or even optima on their website says there is not a battery available from my car or even my daughter's C class was just blows my mind because these are 2 very common cars on the road.
So what is so special about these cars and this battery that hardly anyone else seems to have one?
Mercedes wants $350 for it only 2 year warranty but I think I'm going to take the $190 route from Autozone.

Anything longer is possible but ya never know.
Have battery tested first by auto zone then replace if bad as could be something else.

Or just go to the dealer, load up on snacks and get a free car wash while they do everything. All those places you'd have to install the battery yourself. Several of them use to install for free, but I guess there were too many screw ups with Mercedes so now they either charge extra or won't do it on an MB.

The Pep Boys Bosch AGM battery was as much as the dealers installed.

The $150 off $300 makes it competitive with the dealer, otherwise the dealer is normally the most expensive.

As for the types, the Varta OEM battery is Johnson controls and batteries from Autozone and Advance Auto are also Johnson Control batteries. I believe Pepboys carry both, the Bosch is Exide and the Champion is Johnson Controls. Exide had to file for bankruptcy a few years back as Walmart dumped them as their supplier.




I drive lately with DPF gauge and as side monitor voltage and don't see anything smart about it. After morning start it charges at 14.5V, what is killing voltage, only later in the drive to switch to 13.6 or plain battery power at will.
So no-so-smart charging is killing the batteries. I did not see them lasting longer than 4 years in those cars. Than again, if you save fuel this way, maybe it makes sense.
The only data you lose by disconnecting the battery is window/sunroof synchronization and time zone on your command center.
I just did that couple days ago and car learn the time somehow, GPS ? But was 1 hr off as time zone was wrong.

Thinking back about it, I am not sure about windows synchronization. For me window synchronization is something done automatically, when I drive, so don't even pay attention.
Had W210 where I was using sunroof twice a year and each time it required synchronization for some reasons. But those are the things that don't stop you from driving.
