Coding new battery

[hiwasss]

I replaced an H9 battery with an H8 battery but the new one doest have a sticker with the part number, vendor code, or serial number. How do I go about coding for the new battery and does it really reduce the life of the new battery if it's not coded?

Do you have a tool to invoke adaptations, such as VCDS or OBDeleven? If not, you're going to need access to one or someone with one first. If yes, what is your current adaptation value?

Battery size is one parameter, but the other is whether it's AGM or not. Is the new battery AGM or not? Was the old battery AGM or not? If it's a H8 AGM (~92Ah), try 4F0915105E for the part number.

"does it really ...", no one anywhere has likely done any level of 10 year testing of various mismatch scenarios to give you a "really" answer to anything along those lines. You can either ignore crap or config crap. The world will not end either way. It's stupid easy to config the adaption. Do it or don't. But do correct the date/time before performing the adaptation so the entries in the history data make sense.

I have OBDEleven and will give it a try. This is replacing an autocraft gold battery (Nov. 2017) that replaced the original battery. I did invoke adaptation when replacing the battery in 2017.

The new battery is DieHard Platinum AGM*Battery, Group Size H8, 900 CCA since they stopped carrying autocraft.


Car was showing signs of not wanting to start after it sat in the garage for two weeks during the snow storms.

H8 AGM is the same battery I have, though I went with the NAPA one. It's all same enough. 4F0915105E is the part number in my adaptation (car came factory with H8 AGM, ie PR-J0B). I tried to use Audi's current replacement order part number, 000915105CE, but the J533 in my '08 didn't care for it. So stuck with the original part number for that battery as already present in my adaptation.

4 years, was the prior battery not AGM then? 4 years is ok for non-AGM, but that's really short life for an AGM. My AGM lasted 10 years and it's still in the garage in good shape (got to love parts cannon approach).

So I dont need the manufacturer's code and serial number?

You need something in those fields. The actual characters of the serial number really don't mean anything other than trying to correlate the battery to the history data entries. You can probably find some kind of serial number on the battery, adapt it to the necessary character count and throw that in.

Some have claimed the serial number component of the adaptation value is DDMMYYSSSS, but the factory adaptation serial # on my car was 580724O095, done on my build date, Aug 14 2008. x8-07-24 might make sense in YY-MM-DD format, but why 58 instead of 08? So would 2021 be 21 or 71? So I don't think too much about it as we have no absolutely correct information by which to decide a correct value.

As to the vendor code, I have no information to say the character set is used to adjust any manner of operation of the J367 or J533. It could be just an extension of the serial number, cataloged for record keeping purposes only. You'll find that like the part number, you cannot just throw in whatever random characters you want, though. Supposedly, "In 2019 Johnson Controls sold their battery division to Clarios, LLC, who manufacture DieHard brand, along with Duralast, Varta, and AC Delco, as well as 20 other brands." But then we see that Clarios is pretty much JCB rebranded, https://www.batteriesinternational.c...attery-growth/

So throw in JCB and call it a day. The part number, and the date encoded into the serial number if the correct format could be determined, if there is one, are the two components that matter.
