Hi, my car has recently been saying battery below 12v. So im guessing I neeed a new battery. I bought it 2nd hand from a Skoda dealer in 2020. So its possible the battery has been in there since new,(2017). Now battery prices range from £110 to almost £300. Went on a few sites and found on GSF a Yuasa ybx7096 , (pic), which they say is compatable. Bought it,thought it was a good deal, £121, reduced from £160, via the usual weekly discount codes.

They current one is a Varta, (picture). But before changing it i noticed a slight difference. The current one say EFB+. The Yuasa is without the plus.

Is this a big deal? I've put in replacement battery, for the car, in google and it mostly comes up with just EFB.

Is EFB and EFB+ the same thing? I can't see any EFB+ batteries online.

I wouldn’t say that was the original battery. Looks like a dealer replacement battery, part number begins with 000. The year is usually stamped on the negative post. That Yuasa battery will do the job.

My understanding is that the EFB+ is a fairly recent upgrading of the EFB - I don't think EFB+ batteries were around in 2017, so your old battery was probably not original.

Did you have your new battery adapted (coded) into the BMS?

Just code in the new battery to whatever you purchased.

I changed my original Yeti battery to a Varta AGM from Tayna when I swapped that out in 2020.

Your choice of battery purchase but just tell the BMS, i.e. code it, whatever you decided on. Ah, battery type and a serial number change.

Thanks all 👍. Yeah the Yuasa battery worked fine. Been on for over a month no problems.

My battery is same, almost, but its a Exide. Here is mine with the logo on it - 2020 I got the car.

I swapped it out today (5+ years old) for this which I believe is pretty much the like for like options. It has a higher CCA at 760 but thats only positive.

Took me 30 mins to install. Bit tricky because of the bracket that keeps in place is hard to fish out.

Do you have to recode the car if you going from 70ah to 75ah ? Thats what put me off the Yuasa and made me go for the Exide. Might work but it will be hurting the health of the battery if I am right ?

Yes, you do. Otherwise the car wouldn't charge it to full. It knows it's 70 ah, but in fact it's larger.

Actually you have to recode the battery even when swapping to exactly the same model / producer.

Did you recode it @Marko72 - sounds like you should have done

@linni I think recoded if its the same spec battery becomes optional. The model / producer will only be for "show" ?

What I have read before in the net, that you still have to recode because the Battery Management System includes in calculations also the age and potential wear of the existing battery and charges accordingly.

I have written before here, but last year I replaced the battery with Exide. Battery guy coded the car with Exide dongle. Did not charge to full, lots of problems. Recoded myself with VCDS. Same story. Went to dealers, they recoded with ODIS (into some strange coding, never heard before of) and everything works fine since.

@linni

I will keep an eye on it but I did a check the other day and it all seemed fine....

Coding doesn't come for free so reluctant to do it unless I spot an issue.

If you have a possibility to check the errors, do it. Mine is like a virgin girl, every time you disconnect the battery it needs to erase the fault codes, otherwise some functions like blind spot etc will not work properly.

I got fault codes. Moving the sterring left to right and driving a bit is the usal way to clear them. Everything is working ok - ACC, Blind Spot lights and so on. Cheers though, will keep my eye out.
