Q: How does Recond mode work?

When you select the recond mode on a charger with that feature you will still charge a battery normally through to stage 5 but in stage 6 it will apply a higher voltage to equalize or overcharge the battery to allow a full absorption charge to be performed. Once this mode is complete it will continue as usual with stage 7 & 8 if all is OK. Otherwise, the caution LED will be displayed and the charger will stop charging the battery until user intervention.
