About two weeks ago I recoded a new battery into my vehicle with VCDS BUT now for various reasons ( too lengthy to go into details ) I've re-installed my 4 year old original battery back into place. I've recoded it back to the original default settings i.e. JCB, Fleece, 1111111111 etc even though it's actually a Skoda Varta battery with all the BEM details still attached to it. My question is this - will the vehicle remember the old settings/working parameters/age etc or will it treat it and set it up as a new battery because I've done two or three different recodes prior to re-installing it?

from what i understand, it'll treat the battery as a the same one, but I'd probably saved you'd be better changing the serial so the car treats it like it's 'third' battery.

 

As long as the battery details which are saved (AH and battery), the car will know how to charge it up.
