Hi there, 

 

I'd like to know what type of battery do you have? 

My Scala is 1.0 TSI 116PS equipped with a 12V 49Ah 320A DIN battery, and lately the stop start system stopped working most of the time. 

I own the car since September 2020. The car was assembled at 02/2020 and so is the manufacturing date of the battery. 

I drive approximately 45km a day to work and back home. Overall made ~8000km. First five months the system worked flowlessly but now it berraly works. Battery test done by service sais the battery good but needs to be recharged... 

Am I driving less than required to recharge the battery during daily use? 

The system sais "Power consumption is high". 

When I checked Varta website for compatible EFB battery, it suggested me the 60Ah battery and the 70Ah battery. Am I missing something? Why would the manufacturer place small battery in the first place? 

Any thoughts and recommendations will be accepted. 

Gary. 

There are 6 common sizes of car battery.

 

L1, L2, L3, L4, L5, L6

 

All 6 batteries are 175mm wide and 190mm high.

 

The difference in size of the 6 batteries is the length. Approximately in inches, the batteries from the smallest L1 size to the biggest L6 size is 8", 9.5", 11", 12.5", 14", 15.5".

 

So as you can see, the batteries go up in approximately 1.5" increments.

 

The battery that you have is the smallest L1 size.

 

You can see the 6 battery sizes here in AGM format.

The 1.0TSI engine is small and doesn't need a big battery. What it needs is a high quality battery.

 

If you live in a cold country such as Scandinavia you might need a bigger battery.

 

Skoda have fitted your car with a low quality and cheap EFB battery. You need an AGM battery. Notice on the yuasa link, that the L1 AGM battery has a CCA (Cold Cranking Amps) rating of 520A. Your 320A rating is a joke. No wonder you are having problems.

 

Yuasa and Varta are both top quality makes. However, they do a range of batteries, so make sure you get a top model such as the 9000 series (in the Yuasa range).

 

Looking at the prices on ebay, you might as well go for the L4 size if it will fit as it doesn't cost much more than the smaller batteries. However, the bigger you go, the heavier the battery gets. So maybe go for the L2 size, if it will fit.

I have installed Varta Silver Dynamic AGM 60Ah 680A - L2 with very good result.

The "320A" rating for CCA is the DIN rating, that equates to 640 SAE which is the same battery as my wife's 2015 VW Polo 1.2TSI 110PS 6MT has, also my younger daughter's 2019 SEAT Arona 1.0TSI 115PS 6MT has, and both are 59 or 60AHr EFB, AGM is better in my mind though, I've already bought a 70AmpHour 760A CCA SAE AGM for that 2015 Polo - but it doesn't seem to need it yet!

Wrong size of new AGM battery quoted!

I have 2019 Scala 1.0 TSI 115 and I had battery changed at the service center. It was factory original, EFB 59Ah 380A DIN, 640A EN, so these parameters seem ok to me. Beware - new battery parameters must be coded in car. AGM is better (and more expensive) than EFB.
