I saw this immediately when I put an Interstate AGM battery into the prior RV that used a Magnetek 7345, 13.8 volt converter. When discharged even slightly, the battery would pull pretty high current, then taper off to almost nothing when recharged. It appeared that a multi-stage charger would offer no benefit whatsoever. The specified float voltage for many AGMs is 13.5 to 13.8 at 77* F.
- They seem to defy all forum-knowledge by both floating and charging (when camping) from the same fixed voltage ... ~13.8 volts from a stock converter.
