My expensive ($1500) 4 stage charger for my deep cycle batteries (120 ah 12v) readily runs the initial charge stage @ 16 volts/500 mah for approx 1 hour (de-sulphation stage) and up to 70 amps during stage 2 (absorbtion stage) whilst holding constantant voltage @ 13.8 volts. cycle goes in to float @ 14.4v when fully charged.

These batteries drive a Min Kota trolling motor on my bass boat and are always fully flat after a tournament (under 1.2 volts per cell), they are into their 5th season now and still last 2 days of constant use with a 40 amp peak draw!
