I am currently trying to charge an Optima battery that requires a regular battery in series with the Optima. Sometimes I have luck doing it that way, sometimes I don't. All in all I HATE Optima batteries. I don't have enough of them laying around to justify buying a another charger just for Optima's...

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
