Unfortunately for me, I now reside in Coffs and originally purchased the battery from Battery World in Brisbane. How are Battery Worlds back up service? I'd have to look, but I'm pretty sure it's just out of warranty.
I must admit to having reservations about paying so much for a battery in the first place, not expecting to get twice the life/performance given the purchase cost but this particular battery is quite compact and it freed up a bit of space in the already cramped location under the seat, so that swayed my decision.
Time for some legwork to get to the bottom of this.
