I just came cross Oliver Jobson's CTEK Battery charge users guide, and he said "only use RECOND mode with a standard Lead Acid Battery or Enhanced Flooded Battery (EFB) (this includes calcium EFB batteries). RECOND will not help an Advanced Glass Matt (AGM) Battery. It could even harm a Gel Battery", but the CTEK MXS 5.0 manual doesn't mention it, has anyone used Rcond mode on Auris hybrid AGM Battery? I am thinking to order a CTEK Battery charger, but don't know if I should go for CTEK MXS 5.0A or CTEK MXS 3.8A.
