  • I'm a bit puzzled by your post #20 where you recommend renewing the battery if its greater than 4 years old, do you mean renew it if its displaying problems?.

    I have a smart charger (Ultimate Speed 3.8A) that I bought for €20 in Lidl around 10 years ago purely to charge up two old 7.5AH house alarm batteries that I use to power garden fountain lights, have never used it yet on any of the 4 cars in the family but its interesting and IMO a excellent charger. I have also attached a volts vs SOC% table which gives some idea of the state of a battery but the battery voltage should ideally be taken with battery disconnected from any load.

  • It does say to make sure you replace like with like.

    As for the other comments above I think it's up to you to make your own judgement on your car.





  • It's definitely prudent IMO to code your battery, if recommended, why not?, but would be interesting to see if the new battery longevity is enhanced by coding vs no coding. I carried out a good few tests on a battery that I renewed after almost 12 years purely as a precaution and I reckoned that it had ~ 55% SOC left when I removed it and its internal resistance had increased by around 50% so not a lot left in it from a cranking point of view due to voltage drop so based on that alone it cannot but help to code the new battery but I have to admit I'm a bit skeptical still but why take a chance?.





  • Most of the manufacturers Ive worked with dont have any recoding procedure - This year alone Ive probably fitted close to 150 batteries- not one of them has been recoded to the vehicle.

    The instructions we have is that the smart alternator will basically self learn the new battery.





  • What about VWs built say in the last 4/5 years or so, any coding recommended here?.

    Just rang O'Connell Bros. Cork who install hundreds of batteries and was told that VWs do NOT require coding. (Although I think my VCDS can do it).

  • Virtual reality at its best, just downloaded these numbers via VCDS, car (January 2018) has 13,070 kms (8121 miles) up, all short runs in daytime mainly, stop/start rarely enabled.

    I think the BMS system maintains 80% SOC.

    And some more info whatever it means.

  • Ok, this the info from the adaptations in the Can gateway (using VCDS) , I can change the battery capacity and the serial number but not the battery type, I've read that all the VW models use 1111111111 and just change one digit or add a 0 and this is enough to tell the system that a new battery has been installed, if your new battery has a serial number then put this in, also change the AH rating, if different.

  • I changed the battery in my 2008 Audi A5 and went at vcds to see what the story was.

    I think from memory now that the 3.0 TDI from that era required the full coding with battery type and serial etc but mine didn't or needed a more basic reset. It's about 6 years ago so can't really remember.

    I've heard many stories of bmws eating new batteries fitted by people who didn't code.





  • News flash: For the first time in 57/58 years without using a charger on any of my cars I connected my (smart) charger to the Polo battery and within 10 minutes it c/o to trickle charge which confirms more or less that the battery is indeed fully charged and the 82% indicated battery charge level (VCDS) is to be expected with a nearly 3 year old battery so I will monitor it every few months from now on but no more charging.
