Batteries have been in the cars for long. This doesn’t seem that interesting subject, as previously you just removed the cables, and changed it. But not anymore.
In new cars, eg. some VAG brands like Audi, you will have to recode the car to detect new battery correctly Audi A8 (4E) Battery Replacement. Also if there is some faults on car, it might be that the car doesn’t start at all after removing battery without some recoding.
I had in my Skoda Superb 2010 around 2-3y old battery (part of VAG company). With heavy use with Webasto heater it was quite bad shape and didn’t start anymore in -20C. I have VCDS+cable but choosed the safer and faster way (kind of). I don’t have that 61 battery regulation module + I looked from few places in the net + asked that this should be safe.
So unscrewed one 12mm bolt holding the old battery, coupled with cheap Motonet battery cables spare 60AH battery to paraller to old battery, or actually the cabels to car from the battery. Then removing 10mm bolts from – and + and then removed the old and installed new 80Ah 720A battery.
Everything went smoothly in 10-15mins and didn’t have to set windows or clock or anything. I will later on update some more VCDS related tunings I have done + are going to do for the same car.
