Hi, 

 

I've just picked up a 2015 Yeti and I think it's on its original battery. I have a couple of queries and would be grateful if anyone could help? 

 

1.It has stop start so does the battery need 'recoding' to the car? Think I'd be going to 70ah (original is 59ah)Would an obdeleven pro allow me to do this if I need to?

 

2. All the EFB replacement batterys seem to be a good few mm longer than the original battery 278mm on an 096 battery so not sure the jacket is going to fit. Can I run the car without a jacket or is it essential? And anyone know where I can get a bigger jacket? 

 

Thanks in advance, just in a rush to get battery sorted as doing a long journey soon. 

1 is yes and, not sure

2 is I didn't bother putting it back on and it's fine. It's hardly ever -10 in England these days !

Thanks. Good point, I've never had a battery jacket on any other car and the batteries have survived relatively well. I didn't know whether these start/stop batteries were extra sensitive to the cold ❄️🤣. 

It's heat that they don't like more than cold. 

I still wouldn't bother. If the engine is running that hot on a Yeti, you have a bigger problem!

You can push and pull to make the best fit you can of the jacket when using an 096 battery but it will look like Alexis Sale wearing his 😁 it will however give it some thermal protection if you think it is needed.

 

For me it was more an aesthetic thing, with or without the jacket the underbonnet view looked rubbish compared to the MK2 Octavia with its plastic battery box.

 

So I did some looking and measuring and decided that the battery tray was the same as the Octavia and an OE battery casing and cover should fit, I bought one dirt cheap from Ali-Express but it was a genuine VAG part made for their local market, it fits perfectly and looks the part, the engine bay looks finished now.

 

It was a bit of a squeeze to fit the sides and thread the cables through because there is less space around it than on the Octavia.

 

I thoroughly recommend it.

Thanks. I will get a bit rough with the jacket and see how I get on 🤣🤣

As you have an EFB already on the car with a 59ah battery, the ABS site offers a choice of two.

See here. www.advancedbatterysupplies.co.uk/agm-batteries/

And the 096 EFB & AGM recommended are both 75ah. Both are the same size.

 

You can also type in your reg number on the main page and it will give you the correct type.

Yes, especially if it is different. Should do.

Original is an 027 not an 096?

I got a Bosch S4E08 EFB Stop/Start 096 70AH from Tanya - was way cheaper than eurocarparts price - they seem to have gone so expensive of late 😬

Hello John, gotta new motor.

..when I replaced my battery (SS), the dealer just disconected the old one, and put a new one in.....did not need "re-coding", and it worked just fine....

They may have kept it live with leads and another battery / installed identical battery? 

..nope....I watched them do it. In fact the girl from reception came out and fitted it on the forecourt while I waited.....I actually queried it at the time and was advised it was not necessary.

 

It was a completely different battery, as they advised the one I had (original battery), was a known "problem" type.

 

Since I had the car, up to changing the battery, the SS hardly ever worked unless I had driven a long distance, (typically 50+miles) before it started to work, and when I checked it, the voltage was always low. After the new battery was fitted the SS worked pretty much all the time.

Exactly.

 

Arguably under the bonnet subject to the heat cycles of an engine is the least desirable location for a car battery!

 

Heat can cause deterioration in performance which goes largely unnoticed in warmer weather but bites you in the bum at the first cold snap, we've all been there!

 

Personally I'd have stuck with a standard size battery and cover but hey ho.

 

I have had a couple of batteries fail completely without any prior slow cranking etc in the height of summer.

 

Most manifest during winter but yes, I think the damage was done during the summer.

No, it doesn't need recoding .

 

But beware of garages and some other sharky places that will tell you it does.

Why wouldn't you though ?  It's so simple to do the coding. I guess there is a, if you have something to do the coding with, to add there.

But seeing that I do then it is something I always do when swapping or helping others swap VAG batteries.

Maybe it's not that necessary if swapping like for like but I've never been given any technical proof of that and nobody has ever said it does any harm to do the coding.

I gave advice Aubrey. The short answer is some dodgier garages will try and con the guy for £50-80 for a completely unnecessary scan.

 

My own dealership advised back when I changed mine that the battery didn't need coding . Those MOLL batteries were a poor battery anyway. I had one on my new Yeti originally. They have since gone bust .

I can code my own, as I have an Ancel 700 scanner, so it's no problem to me to do so, but the op obviously doesn't have a scanner, so it was just a reply to him to save him from getting shafted .

It's now up to him really. 

Have a great 2025

You don’t need to code a new battery - it will obviously work and provide power to the car - but unfortunately with the battery management and charging systems on these cars it should be coded. If you don’t do it the car will treat the new battery like it was the old battery and that could be detrimental to the service life of that new battery.

Do or do not, as Yoda would say. Happy new year 🥳

This seems to be the consensus from multiple sources - if you don't tell the car it's a new battery, it could end up with the new battery malfunctioning or not lasting as long as it should. It might be true or it might be a myth, however I decided to code the new battery just to be safe rather than run the risk and potential cost of ruining my new battery.
