Looks like my battery of 8 years packed it in officially. Of course, on a dark and rainy night...
So, I am interested what size batteries you are running, particularly if you have a factory 12" alloy and, even more particularly, running Yoko A539 12" tires. Currently, my spare is still on my last tire setup, the Yoko A048R, which has a much smaller diameter overall. Sure, I could remove one of my road wheels, stuff it in the boot and measure BUT you guys probably can rattle off the perfect battery in seconds...oh, and its cold out:-)
