just-a-hacker,
Yes, the stuff from my NY garages are all moved to NC, but it is in total disarray.
Does that Optima charger do 6v and 12v?
Good luck with the Optima - one of my three 6v Optimas went "dead" several years ago, and I was told all the stories about bad Optima batteries.
I followed the correct recharge procedure and got it working. It is now over 12 years old.
I do not maintenance-charge them over the winter, or before start-up in the Spring. They start my trucks every spring, after winter hibernation.
