Constant current battery chargers

They're all about the same overall. But if you could get a higher voltage Paramode, IMO, it would be the fastest due to its higher voltage absorb phase. But you can't technically so either IOTA or PD or Powermax. I like Powermax cause you can get it with adjustable voltage (I think), it's 100A, and it runs from a 15A VAC circuit (cause it's PF corrected).

At 20C the "fastest" way to SAFELY recharge FLA batteries is to apply 14.8 volts until such time as the current drops to less than 08% of total 20 ampere hour rating. Any other formula for 5% antimonial batteries is bogus science. If power runtime is not an issue, apply 10% of total ampere hour rating until such time as 14.4 volts is reached. For top charging apply 2% of ampere hour rating until such time as 15.0 volts is achieved.

Another golden piece of info from MEX!! Was that .08% or 8%??? Forgive my stupid question but do you put it into float at that point or perform the top charge portion?

I need a big amp, PF corrected, power supply to try all this out.
