With the trickle charge, I'm sure you'll have decent batteries but perhaps a bit of sulfation so the EQ cycle is an excellent idea anyway. You will want to first fully charge the batteries and then...being sure they are topped off properly with distilled water...charge them for 8 hours at 15.5 volts. (Caps off and good ventilation!) Max Current should not exceed 30 amps for the whole group or 10 amps per 12V pair.
