...check out auto zone they make a damn good battery. ive had the same one in my truck for 12 years or maybe 14 but its almost indestructable. i left the radio on once for several days that i discovered when i went out to move the truck and it turned over like a champ and fired right up.
I've got a DuraLast Gold in my daily driver, and it's been fine. I pathologically detest AutoZone, however, and try to avoid them at any cost. Long story.
I've been running a Turkish-made Mutlu battery for like two years now and it's still cranking strong, but we don't have real winters over here, so...
For some reason I don't think we get Mutlu batteries over here
Very appropriate timing, however, given that it's Republic Day over there today. Ne mutlu Türküm diyene!
I put in the Advance group 49 (in my gasser), its 900CCA, 950 cranking amps, and the OE CCA for diesel is 850CCA. Have run advance batteries in several cars for quite a while, (like RP, and his autozone's) with no issues. I had them test it when I bought it to make sure it was fresh, and it spec'd at 1010 amps. 40min more reserve than the Bosch too.
Its black and classy. (some are white) Guys on the bimmer forums run these as a cheaper (more realistic) alternative to the Propeller batteries.
AutoCraft Gold Battery, Group Size 49, 900 CCA 49H8: Advance Auto Parts
Sadly, we don't have Advance Auto Parts over here. Oregon's auto parts store landscape is weird. It's like someone missed geography class and thinks we're in the Midwest or something.
Are you referring to CCA when you say Ah?
No, I'm just a dipshit and typed the wrong thing. Thanks for pointing that out - I'll correct it to save on confusion
FWIW, both of these batteries have 100 Ah capacity, same case size, just different CCA.
Looks like I'm going to return it in the AM. I'm vacillating on whether I want to pony up for an AGM at this point, since a local truck shop in the weird industrial park I live in can get me an Odyssey Extreme. I've had awesome luck with them in severe service applications in the past, and for my use case, the fact that they Odysseys can be run very low without destroying them is useful.
All this faff about a stinking battery. Last time I get a part direct from Mercedes if I can avoid it. Of course, all these damn batteries are made in the same plant in Mexico by the same laborers who just pray they stick the right sticker on the casing or they'll get their heads cut off by a drug cartel enforcer, so I probably should just shut up and quit bitching about it
