This is the battery to get. Everstart Maxx H8My battery died. Should I buy a new battery from a BMW dealer or will an "ordinary" battery from Sears and the like be alright? Advice please.
No, not for E46; only for newer BMWs.I am told that there needs to be some kind of electrical meshing of a new battery with the car's electrical system. Is this true?
I just put a new one in my car, 760CCA from Advance Auto. H6AGM $176.99 but had a 25% off coupon code. Slightly smaller than the one I put in 5 1/2yrs ago but not enough to be concerned about. shop.advanceautoparts.com/p/autocraft-platinum-agm-battery-group-size-h6-760-cca-h6-agm/10210829-P?navigationPath=L1*14920%7don't buy a used battery , buy a new one , these are not exceptionaly expensive , and at least in Greece where I am , a Bocsch S5 (S5008) (77AH and 780A) that meets or exceeds the requirements unless you have a convertible is about 80 euros and comes with a 5 year warranty
I see a lot of discussion on here about various brands. Be aware that the battery sold by Walmart (everstart brand) is made by the same parent company (Johnson controls) as the Varta battery that was OE BMW (Varta was owned by BMW owners). Varta also make AGM batteries but have not recommended that for our e46. You can check that out at their Europe vehicle battery finder.
Point of my post is Varta ( now Johnson controls) make batteries for many brands so when you buy that Walmart or Interstate battery you are getting the "black line" but it is the same manufacturer (yes Johnson make Interstate batteries too). Typically the black line meets the minimum spec (cca) for the intended vehicle.
I worked for the Quandts and buy the other brands knowing I'm still getting a Varta battery, just not at BMW prices. Same thing for my Aston Martin. My Walmart battery for $180 has the same plastic moulding lines and is exact to the battery replaced. It should be - it was made in the same factory by same folk, only when they put the sticky label on it for retail sale it was priced at 1/3 the cost the Aston Martin dealer sells it at.
Just find it funny when I see the debates over brands - when the only real difference is sometimes the plastic colour used, the label and marketing approach. The AGM battery made by Varta for BMW, Audi and MB was intended for the Start/Stop Cars.
What is the logic of not using AGM for the e46 ?
AGM did not exist when E46 was made, that's the only reason it's not OEM.
In the end, it's a 12V DC battery, so of course you can use it in an E46.
True to some extent, BUT!!!. The point of my post was to support that the Walmart H8 battery and indeed the Everstart and Interstate lines are made at the same location by the same people and the same equipment as the battery you find at the BMW Dealer. And also even with the new IBS system it is not a requirement to buy a dealer battery or in fact have to program it to the module.
