What you need to do is charge the main battery for at least 48 hours to desulphate it . it will generally recover then as long as you use the car regularly .. It has probably not been used much the last 18 months ... It wont charge properly by driving the car it needs those 48 hours on charge ...
If you do buy a battery for whatever reason always get a dealer quote first , they are competitive ..

Hmmmm, now slightly suspicious about the diagnosis of a faulty auxiliary battery being the reason for the S/S not working. Will look into getting a charger (one I have only suitable for batteries for cars up to 1600cc). Quote from dealer is £306 which seems a bit steep?

Ref the suitability of your existing charger. The manufacter's comment about only suitable for up to 1600 cc is bull. Put simply it will just take longer. Obviously other aspects of the charger do have to be taken into account
