Car battery left me stranded - again

So, for the 2nd time, my car battery died and left me stranded until Roadside Assistance came and towed it to a parts store for a new battery. I had absolutely no indication the battery was going to fail. Result: over 3 hours late for work

Confession: The last time this happened was four years ago. So, the current battery lasted 12 months past its 3 year warranty.

My proposed solution: Change out the battery when the warranty expires. Please feel free to offer another solution that you use.

You might ask why I didn't just have him jump it. And the reason would be that before, it resulted in some electrical issues and I swore I would never try to jump it again.

I would love to hear others' experiences with their battery dying.

I bought NOCO battery jumper . It's small fits into the trunk and can boost your car 30 times on 1 charge . This way you dont get stranded and removes the need for jumper cables .

I just changed my factory battery. 13 years on a factory battery is pretty nuts.

Wow. That's great!
I see you are from Canada. So, that might be the difference. I live in Savannah, GA.

I've had pretty good luck with the factory batteries as well. They certainly last longer than the wal-mart specials that are out there.

It might be counter-intuitive but it is heat that kills a battery, not cold. So it doesn't surprise me that a battery in the south takes more of a beating than one in the north.

You had your car towed just to get a new battery? Why risk damage to your car? I would have just left it and took an Uber to an auto parts store to grab a battery and a wrench.

Anyhoo, I like your idea of just replacing it after the warranty runs out. Funny, a few days ago I was thinking I should think check the date on my battery and replace it if it were too old. As per usual, I still haven't done it lol.

Sounds like that was the best decision for you - but not for me. It was blazing hot, I didn't know exactly how to change it myself, and I was dressed for work. It took the guy who changed it about 30 mins. He really struggled to get it in there (the thing was heavy) and needed my help to move some stuff out of the way as he was trying to get the battery in there. He also needed an additional tool to tighten something where the battery sets.

My original battery had to be replaced after 10 years in service, and I decided to buy an OE replacement (@ $167 MBZ dealer)... I changed it on Dec 2016 and haven’t had any issues. I’m very happy w/OE but are sure there are cheaper aftermarket options you can chose from.

Thanks everyone. Looks like next time I will change it myself with an OE battery soon after the warranty expires.

Many auto shop yokels don't know the MB hood raises to a complete vertical position by pressing the little red button on the driver's side strut. Once you get the hood out of the way, it's not tough to wrangle the battery out of it's nest.
There is a lower bracket that secures the battery with two 13mm nuts to hold it in place. I used my 3/8 ratchet with a 12" extension to loosen them. Luckily I also had a magnet on a stick because the nuts are not going to stay with the socket.
An additional note for ALL: My shop manual says "regular batteries" don't have the reserve capacity and only AGM type should be used. Yes, it's going to cost you $200, but much better than OEM option.

Make sure it is the battery and not a drain. I had a seat controller that was drawing 2A. Killed the battery very quickly when the car was not running.
