Hello!

 

I've come to a point where i'm forced to change the battery on my Skoda.

The question is: does the battery need any reprogramming or is it a simple swap?

 

The car is 2012 Skoda Octavia combi, 1.6TDI (77kw).

The old battery that is getting switched out is a Varta, which i believe is not the original part.

New battery is an Exide EFB battery, which i believe is also used on entry level start-stop system cars.

So becuase it is an EFB battery, do i need to program it as well?

I got an EFB, because i was told that's the recommended battery replacement for this model variant.

Does the car have start/stop?

If not there will be nothing  to program.

 

It does not.

Thank you Breezy Pete!

Trouble is, now you don't really have the right battery for your charging system. 

I'm sure it's fine.

Exide themselves say the EFB battery is compatible with conventional powertrains.

And probably will benefit from longer lifespan.

Interesting. I thought EFBs were like AGMs, in that overcharging is a possibility on fixed-voltage output alternators, hence the 'birth' of battery management modules and variable output alternators that go with start/stop cars.

You don't have any module connected to the battery negative post do you, just wires?

As OPs car does not have stop-start - and therefore is not a 'micro-hybrid' would it also not have the energy recuperation system? - In which case, EFB battery should be OK (but pricier) to fit. 

I hear what you're saying; but I believe the energy recuperation thing isn't the whole story with why EFB/AGM have variable voltage charging.

These batteries have lower internal resistance than conventional ones, so for a given charge voltage, the current flows will be higher into the battery. That's great when the battery isn't full, but not so good when it is.

I did not notice any extra bits on the positive side when changing the battery.

There was 2 different wires leading to the positive side terminal though, if that's an indication of anything.

The battery management module would be on the negative pole, not positive, if you had one.

 

Oh, then definitely not. The negative side was about a 15cm piece of wire straight to the chassis.

Yes, so your alternator is conventional, fixed output voltage (although that does vary with temperature).

 

Let us know in a few years how it's doing. 👍

Will do.
