AC Delco battery from Holden. 850CCA which is listed for V8 Ute. That’s what is in our VE V6 Calais.
You can then also enter the AC Delco/Holden Monaro competition having spent over $100 at a dealership, although it’s pointless because I’m going to win it.
They are a good battery and a factory fitted battery. Price is competitive with any other.
Make sure you connect the vent tubes that come with it.
