Re: Measure coach battery capacity - by Wyatt Reply #27 – July 30, 2013, 06:55:10 pm My Progressive Dynamics PD9200 Series RV Power Converters has a built in four stage smart charger. The four stages are Boost, Normal, Storage, or Desulfation. "BOOST Mode 14.4 Volts - Rapidly brings the RV battery up to 90% of full charge.NORMAL Mode 13.6 Volts - Safely completes the charge.STORAGE Mode 13.2 Volts - Maintains charge with minimal gassing or water loss.EQUALIZATION Mode 14.4 Volts - Every 21 hours for a period of 15 minutes prevents battery stratification & sulfation - the leading cause of battery failure." Most late model inverter / converter chargers have smart chargers with 3 or 4 stage automatic charging functions. The Progressive Dynamics converter charger is aftermarket. I believe most of the chargers found on later model Foretravels are smart chargers with the Desulfation mode. Quote Selected
Re: Measure coach battery capacity - by Wyatt Reply #28 – July 30, 2013, 09:37:31 pm Do not use Desulfation, also known as Equalization setting on sealed GEL or AGM.Equalization stage charges at a higher voltage, that will cause electrolyte to vaporize, which is no problem for wet cells with removable caps allowing replacement of evaporated water. Vapor released from AGM & GEL cells cannot be replaced, causing battery to fail. Quote Selected
