Apologies for starting a new topic after the last one - 

 

 

I've since had to take the battery off to charge it another 4 or 5 times, so I think it's time to bite the bullet and just get a new one, can't stand not knowing whether or not the car will actually start! 😡

 

Can anyone recommend me a battery and a decent supplier for it please? The current battery is EFB, but I'm going to change it out for an AGM.

 

So am I right in that I'm looking for a 096 AGM battery for a 2017 1.4tsi pre-facelift? Thanks in advance.

My 2015 1.4TSI doesn't have an 096 battery, it's a smaller one - but I do intend to fit a Varta 096 AGM battery when the current one fails, which will need a larger fabric cover to fit (which I already have).

My current battery isn't 096 or AGM, but I think that's the way forward unless someone tells me different? 

 

No cover on mine now, so no worries on that front! 🤣

I agree, which is why I posted that's what I'll be doing

 

I've had good experience with Tayna and Varta batteries in the past so this is what I'll be getting https://www.tayna.co.uk/car-batteries/varta/e39/

I replaced mine in a 2016 vRS for a 096AGM Halfords (Made by Yuasa apparently)  battery and it works perfectly. I had to borrow a diagnostic machine to change the coding to recognise the new battery as AGM, but I am very happy with it.

 

When changing the battery I disconnected it completely and had loads of errors come up, but after driving a short distance they cleared, which is normal

 

I went with the Halfords one for ease of return if it ever develops a fault (Has 5 year warranty). I can get the car started or towed to Halfords and get the battery swapped straight away

How much is a battery for the 1.4 tsi, mines a 16 plate

The Varta 096 AGM is coming in at about £130, the EFB version is around £100.

Ordered the Varta E39 for just over £130 delivered and it's arriving tomorrow, thanks for the replies. 

 

The car's going in to a local VW specialist next week for a once over, and they're going to code the new battery on at the same time. 👍

And fitted with no problems at all, hopefully that fixes everything. 😁

Is there any difference between the life expectancy of the AGM and EFB?

AGM are more durable than the equivalent EFB. They take more abuse electrically and are more resistant to vibration damage. 

I replaced the battery for my vrs tsi last week. I phone up Skoda Winchester just for a laugh and was surprise it was only £140 for a battery for them.

 

bought it and replaced at home. The only thing I had to do is change the Ah rating using VCDS from 69 to 70. The original was 69 so i guess it came out of the factory with that. 
 

This is my first experience of start-stop batteries, generally pretty unimpressed that’s its lasted 5 years - however unsurprising.

Are they both equally vulnerable to deep discharge?

Did you reprogram the serial number too, so that the car knew you had fitted a new battery?

Mine has also lasted five years so far, despite frequently sitting on the drive for weeks at a time, even before the current situation.

correct yes. However I highlighted the ah setting as it was interesting that the car had come out of the factory with a 69ah and now skoda recommend a 70ah.

Not inherently, this might be a useful read Learn what differentiates AGM from other lead acid battery types

Any 12v battery can be discharged but AGM is more resistant to the sulphation damage caused by it. There’s a greater chance of recovering an AGM over an EFB, likewise EFB over Standard flooded battery but it’s still better to prevent discharging or permanently running at the low end of the 12v to 13v operational window of any battery in all cases.

 

Vehicle electrical circuit temporary fluctuations between 6v and 15v are normal. Resting voltage below 12.0v is not. 

I ended up with a new battery on the weekend, original lasted nearly 7 years and 70k so I don't think it was a terrible innings. Told the AA guy I wanted AGM and he fitted a Bosch one. Coded correctly as I made sure to check afterwards with my OBD Eleven.

 

Looking at prices of EFB and AGM I can't see the point for going EFB, its a little cost saving that makes sense for Skoda selling hundreds of thousands of vehicles, but for one person buying one battery, just spend slightly more for the better, more durable battery.

It's awkward to measure the true resting voltage because so much load is put on it as soon as the doors are opened. I routinely measure less than 12 V on the cigarette lighter before turning the ignition on. While battery probably is on the way out it does seem to be operating perfectly for now.

There are 2 ways to take a reliable reading. Disconnecting the battery and use a decent digital volt meter across it is the ultimate best way.

 

Second best way is to connect up a digital meter to the battery and close the bonnet with the device on the windscreen/outside the engine bay. Unplug every accessory from inside the cabin, close and lock the doors. Leave it for approx 15 to 30 mins for all the modules to go to sleep and then check.
