Avoid going to Halfords, I mean that genuinely. For some things, especially batteries then the main dealer is more reasonable than you think. Likely an AGM battery, and it needs coded to the car. On a B8 model, I’d say it still needs coded to the car. This can be done if you know someone with VCDS.

Hello Stephen,

Yes, best to avoid Halfords if you have respect for your wallet - also main dealers.

Of possible help:- 

I now avoid Varta/Bosch due to recent dissatisfactions.

I currently favour Exide ( their Premium grade for  those without stop/start.

Have a look at Tayna Batteries website and tap in your registration number, and that should point you to the correct battery - beware, Tayna will likely to point you towards their own brand ( sorry cannot recall the brand name at the moment) but I would simply stick with Exide.

Also have a look at Parts in Motion website - they now do Exide.

For both these companies, look on eBay before committing since they are generally listed as free shipping on there. 
Double check your current battery spec. for Ah and CCA figures and ensure the recommended replacement meets/exceeds these figure. Also check dimensions, but do not ( in caps)use a metal tape for fear of touching terminals! 
New battery will need coding.

Regards,

Gareth.

Nevertheless if it is the original battery it is long overdue to be changed irrespective of any sensor fault.
