Thanks guys ended up buying a Varta G14 last night on eBay - took advantage of the 10% discount + cash rewards so it ended up costing ~$90 more than NRMA.

Delivery was made today (kudos to Trackwarrior for sorting it out so quickly). Also bought a CTEK MXS5.0, would it be recommended to run a charge on the new battery with it prior installation?

Julian the battery is made in Germany, would this still be the "retail" Varta's you're referring to?
