Battery Replacement

[Deleted]

Saw the following article here (thanks to EFF11 For the info) and below is the detail of how to code the change

There are two types of battery used on VAG cars.

Enhanced Flooded (EFB) are essentially standard batteries manufactured to much higher standards. They have twice the endurance of standard liquid filled batteries and are fitted to vehicles with Stop/Start.

Absorbent Glass Mat (AGM) batteries have three times the endurance of standard batteries and are fitted to higher specification cars with higher electrical loads. In these batteries the liquid is absorbed by a framework of glass mats.

You can use an AGM battery instead of an EFB one, but at much higher cost.

These modern batteries required different charging cycles from standard batteries. If you buy a decent battery charger you will have options to charge a standard battery or a smart battery.

This is the reason why the car's battery management system needs to know what kind of battery you have. If you change a battery for one with an identical specification from a different manufacturer you may not see any error codes and it may charge correctly.. If you change to a different battery without recoding, it may not charge correctly, even if you don't see fault codes, and that may affect battery life.

From the Gateway (19) select adaption and you will get the following drop down list.
Select the Battery adaptation option

Gateway Adaption Full List	Battery adaptation screen

From the Battery Adaption Screen you can now change the following values

Rated battery capacity, Battery manufacturer, Battery serial number and Battery technology to match the battery you have fitted.

All of the these values can be populated from a drop down list the only one that has an option list is the Battery technology where you select the value you require.

Rated battery capacity	Battery manufacturer	Battery serial number	Battery technology
		Enter Serial Number

Apparently, in North America the AGM Batteries do not have the "BEM" code or sticker on it. Of course, the AGM battery will have the manufacturer serial number and the rated battery capacity on it but it will the Battery Manufacturer accept a non-standard three digit code such as "DUR" for a Duracell AGM Battery? If so, then we just have to make sure get the correct on by calling the dealership with you VIN and getting the correct battery code that should look like this PR-J1R or PR-J0Z. If not then I guess we are stuck with the EFB versions. Either way the batteries in our cars are are made to last for some time if we are careful to code them accordingly and install them correctly.

One other note: with AGM Battery if use a C-Tek MUS 4.3 charger to properly charge this battery type you will need to use the snow flake mode to be able to properly charge this type of battery.

Thanks for the added Info a6allrd27t, I am not sure if Seat are big in the North America (I know they have are selling in Mexico but dont think in the US) but in the Golf Forums you will see lots of different solutions as North America and Japan all have different setups and rules etc which I have so far not come across on the Leon Side. Happy to learn otherwise.

Re the BEM Code as EFF11 Stated "This is the reason why the car's battery management system needs to know what kind of battery you have. If you change a battery for one with an identical specification from a different manufacturer you may not see any error codes and it may charge correctly.. If you change to a different battery without recoding, it may not charge correctly, even if you don't see fault codes, and that may affect battery life."

Re Charging the new Battery again as EFF11 stated "These modern batteries required different charging cycles from standard batteries. If you buy a decent battery charger you will have options to charge a standard battery or a smart battery." bottom line do some research and know what charger you are buying and dont just go for the cheapest one.....

What OBD11 is allowing you to do is recode it so you can change the battery type, you have to decide when you recode

Hello, I have another question concerning Battery replacement via OBDeleven in a North American 2013 Audi A6. Now in my 2014 Audi S4 when I look at the Advanced Identification it says it is a KWP2000- which I think means it is a non-UDS Gateway but in my 2013 A6 in this same location it shows as UDS. So I tried go to the gateway and then to adaptation but when this was selected my OBDeleven said that something was wrong/failed and try it again. So these are the steps I have tried to resolve the issue:

1. Rebooted my tablet.
2. Run a scan of all devices(control modules) before attempting to go the the Gateway control unit, but it failed as said above.
3. I tried to login and then just pull up the control modules i.e.,the Gateway and then try to do an adaptation but it failed as above.
4. Lastly, I tried a security login and then I did options 2 and 3. Still, unsuccessful.

Just for the record, the software version of OBDeleven is 0.9.2.1, which I hope is current and up to date.

Any help with this issue would be greatly appreciate as it does not appear that I would need to secure login to make changes for a new battery.

One other point, It appears as though the UDS and Non-uds Gateway will accept an AGM Battery as long as the BEM code is there. Unfortunately, in North America none of the Battery manufacturers include a BEM code except for the EFB batteries, so we maybe out of luck as far as that AGM option.

Lastly, speaking of Battery options that is why it is critical that the you know what your PR-code (Production Code) is for the battery in your car, which can be found by calling the dealership with your VIN. That way you do not put a battery in your car that was not intended to power it.

As always, thanks for any advice or help in resolving this issue on my OBDeleven.

sorry missed this. first thing i always do in these situations is to clear app data on your android device

There is further reading on this subject on the Golf Stream obdeleven.proboards.com/post/12489 which explains about cars that have a battery monitor control module thanks to Don (DV52) for this extra info

VW Passat GTE 2017

I replaced 12v battery and entered new battery details as per the above instructions but the new details are not saved, and it reverts to the old battery details despite me having said 'ok' to each new entry.

New battery is a Yuasa and I entered YUA - Does anyone know if that is correct?

I also changed amps, serial number and confirmed its a Fleece.

Edit: I now realise that Pro is needed for this Adaptation - but does anyone know if YUA is correct? Thanks

[Deleted]

northernlad its been a wile since i looked at this subject but from memory the important parts that need coding are amps (if different), serial number just add 1 to the previous number and if you have changed the type then that as well.

Hi All, has anyone done this on an A6 C6 4F via an IOS device? All the menu's etc are different and I'm unable to locate where to re code my battery.

[whataboutthis]

your car is not same platorm so you need to follow these instructions wiki.ross-tech.com/wiki/index.php/Battery_Replacement

But these instructions are for using a VCDS, not obdeleven. Is it possible to do this on obdeleven?

[whataboutthis]

VCDS Screens are different but coding is the same check out www.cupra280.co.uk/Battery%20Coding.html this may make more sense

[sabad66]

Thanks for the link, that’s helpful. I guess there are 3 different ways to do it depending on technology in the specific vehicle

I am waiting for my obdeleven to come in the mail so I will see what options are available after I connect it to my 2013 Audi Q5. Hope it’s the simpler one

[ishah568]

Hallo, sir which OBD II you are using g and software pls.i have the same problem.

[whataboutthis]

If you want to code in a new battery then you will need the Pro License or the Ultimate License (but Unless you are a garage I would not bother with this one)

Either the White or the Black dongle will allow you to code battery if you have Pro License.

[miilits]

whataboutthis I have a gen2 black dongle. ios. provag lifetime, still not possible to code my battery in a8 d3 pre fl. when i use my old vcds cable its done in 3 minutes.

[whataboutthis]

Sounds like a bug, I have certainly coded battery on my 2014 motor with no issues.

[imody4l]

I replaced my battery with the same model battery on my 2013 audi a8l 4.0. Out of all of the videos and articles I have read as far as doing the battery adaptation with OBDeleven, it never said that you have to have the pro version to be able to code the battery inside the app. Not saying its a deal breaker but it would be useful to have that piece of information before buying the device.
