Guys any verdict on whats a decent battery to replace with?  Halfords own brand OK or should I go premium..

Bosch S5 or S6.  Eurocarparts are offering discounts on batteries at present.  You need an '019' fitment, and make sure you vent it!

I fitted a Bosch S5 019, 100ah. Around £100, or even cheaper if you shop around check ECP.

Definitely a bosch - they come with five year guarantee so keep the paperwork!
Richard what's the difference between the S5 and S6?
Smee

the number is usually the years warrenty

What is the reason for specifying the 019 fitment (what is it what does it do?)
Also I've heard of a 130ah version too I think?

019 is the physical shape/size of the battery.  Each battery type is made to one of a number of fitments  which all manufacturers use.  Otherwise called a 'form factor'.  For battery ratings, the standard hourly is around 90-110Ah with a Cold Crank Amperage (CCA) - maximum cold starting current draw - of around 830A.  Petrol engined versions are slightly lower rated as they need less cranking to start due to lower compression and the lack of Glowplugs - which draw a lot!

If you go too high in terms of hourly rating then your alternator may struggle to fully charge the battery as the alternator and battery are matched within a range.  130Ah is on the upper limit I suspect.  It just means it will produce output for longer, but needs a bigger charger to keep it topped up.

So for the avoidance of confusion this would be the correct battery (not recommending the site or the price just enquiring about the spec)?

The picture is wrong, but the description looks right.

It actually looks like this.

When you replace it, make sure you keep and reconnect the vent hose and put a plug in the other vent (they're holes in the side and plugs are moulded into the battery top.  Just snap off and insert.) so you vent gases overboard.
