6 volt vs 12 volt Trojan batteries.

Works very well.

Actually, my L16H-ACs have very specific guidelines as to bulk, absorption, float and equalization voltages.

EQ is 16.2, which is unfortunate as neither of my charging sources (Xantrex 2000XC and Blue Sky solar controller) will reach that number, 16 being the highest.

FWIW, the Balmar Smart Guage gets upset with a little more than 15 and gives me an error message. The good news is that I never see it unless it's reached C100 (fully charged)...

I meant more as to guidelines about when, how and how often. Although, that may have changed (level of info) in the last 4 years. Good news is the T105s are still going strong and they work hard.

Good luck with it all!
