Maybe it's because I have twenty-three grand worth of batteries at risk that I am so sensitive about this. What some folks consider "chump-change" means eating tortillas and salt for a month or having a normal diet.
The formula DEMANDS 5% of ampere hour amperage and it demands starting with a full as possible battery and it demands that charging cease when voltage rises to 15.0 volts. For benefit of some I can repeat TWICE PER YEAR on an otherwise floated battery, and as often as once every two weeks on an off grid battery that is cycled daily and manages to have a cell that slumps specific gravity despite trying your best to arrive at full charge daily.
I would be happy as heck if a battery came along and had fewer demands than a Hungarian Movie Actress. I would MUCH prefer to spend my time elsewhere. But the way things stand now if I ignore the few minutes a week needed to keep the monsters happy I end up having to scramble for money to cover the cost of premature battery death. It's a free-world. Do as you wish. I do not criticize people who destroy their batteries by neglect and remain silent about it.
Is 15.0V for top charge? What do you suggest for an equalize charge? 16.0V? landyacht318 and I were using 16.0V for the screwy 31 and the T-1275. Landyacht had to go 15.4V to top charge on his US battery group 31.
