Will My Converter/Charger Work With A 100ah AGM Battery?
Question:
I plan on switching to an AGM 100ah battery. Do converter / chargers handle AGM which require slightly higher voltage? I see where some claim to switch between lead and lithium, but I need to know about AGM.

Hello Kg. Most all of the converter/chargers out there will be compatible with AGM batteries. Although each unit will have its own list of compatible battery types. For example, the Progressive Dynamics 4000 Series RV Converter w/ Charge Wizard and AC/DC Distribution Panel - 60 Amp # PD4060K that you were looking at is compatible with lithium-ion, flooded lead acid, AGM, and gel batteries. If you can tell me exactly what model converter charger you have, I can tell you if it will work with AGM batteries or not. In all likelihood, it will.
Most units will work with flooded lead acid, AGM, and gel batteries which all use similar charging profiles. Lithium batteries require a different charging profile, and not all converter/chargers are compatible with lithium batteries. Some have a switch to change to lithium mode like you mentioned. Others are made to be lithium compatible and do not require a switch. Other (mostly older) units are not lithium compatible at all. It really just depends on what model you have and how old it is.
