New battery turned up last night….Great service from Tayna.
But….no BEM sticker…..ls I’ll just change the 68 to 70 and change the last digit for the serial….
I can’t see how the charging regime can determine what battery is fitted if there’s no connect between the battery and the charge controller…even if the battery chemistry is the same…
Whatever…!!

I wouldn't bother changing anything at-all if the old and new batteries are a close match. A fair bit of the time, the battery-manufacturer code is a compromise anyway, serial numbers don't seem to matter, just the battery-size is the relevant bit of info.
I have found before from Tayna that it's a rare thing to get the BEM code anywhere on the battery or the packaging - I have looked on the last few occasions - never found the code, so had to manually enter the info through VCDS. Overall, probably not a value-added exercise to bother with inputting this information.

Thanks for your input Valhalla…
All seems a load of none sense to me…or at least a bit of scaremongering on the part of the car/battery manufacturers..
I could see it working properly if there was some form of intelligence in the battery communicating with the charging system..but there ain’t..so it isn’t that clever.

Just to close this out, I swapped the new battery over this afternoon.Tried to do it with an aux battery but that didn’t work. VCDS reported lots of codes which subsequently cleared after a test run. I left the existing battery info as found in the ecu/ems/bms. All hunky dory now…  |
