Just an FYI, I purchased an Odyssey PC925L for the 'BB' in 2012. It worked great, but then after attending the 2015 Rt-66 and the 2015 WCR, my clutch cable busted. I didn't get around to installing a hydraulic clutch release system until early 2018, so the car sat idle all that time - and the battery was never on the charger.
I thought I was going to have to purchase a new battery, as I put the car on the market the summer of 2018. I thought I'd try charging it and it took a full charge, turned my 9.5 C/R 2056 over just fine.
3 years with no charge, I was happily surprised ... a $130. battery. So much, that I purchased another one for my '71 914.
