Which car battery to buy for MB c300 ? Kirkland or Exide AGM ?

Personally for a c300 I would get an AGM because it has so many electronics draw.

Costco

Costco Warehouse locations sell the Kirkland branded batteries and Costco.ca sells Exide AGM batteries

"Costco's Kirkland car batteries were once the darling of experts and car owners -- the best bargain battery around, boasting a super-long life and an equally super warranty. But Costco has quit selling them.

"Interstate batteries have replaced the Kirkland branded car batteries at your local Costco," ConsumerPete.com reports. Car owners all over the Internet confirm (and lament) the change. However, while Interstate batteries are pricier than the late Kirkland batteries (both made by Johnson Controls), Interstate batteries are emerging as a leader among automotive batteries designed for heavy-duty use.

OK? Just providing info.
Maybe Costco dumped all it's Kirkland branded batteries into Canada? Once they are gone they will do as the American parent is doing.

I like AGM's because they tend to have more CCA and usually deliver a greater starting current.

If you are looking at Exide's AGM battery, CT sells the same battery under it's house brand for typically a few bucks less with a better warranty if I remember correctly.

True, CT gives a 5 year warranty and PartSource gives a 4 year warranty on basically the same battery - the label is the difference, physically.

Well CT and PartSource are the same company

True, I just didn't want to say that they are "exactly" the same battery, because somebody would have pointed out that the CT battery has a black case and the PS battery has a grey case

Apologies for reviving old thread. My mechanic told me that for Merc and BMW do not get anything but original battery from dealership. Is this true?

Just make sure its a good quality battery but it does not have to be from the dealer.
unless he gave you a valid reason as to why you need to?

He said he saw some Mercedes and BMW used aftermarket batteries and vehicle computers didn't work properly. I told him that I got energizer AGM battery from Costco but haven't installed it yet. He said return it and get it from dealer or interstate.

Presuming the battery is in the trunk, probably want to get an AGM here. The OE battery is probably AGM as well.

However don't expect it to really be any better performing than a flooded battery, it's just going to cost you a heck of a lot more AGM is overhyped nonsense (I've owned several and made a post here before about the "AGM scam/myth"), but an interior battery, it's always a good idea to go AGM despite the cost.

LOL not even close. Out of the AGMs I've had I think the YT lasted the shortest time before getting significantly weakened. And that was an old-skool one too, US made. OTOH the longest lasting AGM I had was an old-skool RT. But yeah there's a reason YT is warrantied for only 24 months or whatever, it's not gonna last.
