I have an Outback 2812M charger/inverter and Deka 4D gel batteries. It is driving me crazy to attempt to figure out how to comply with the bulk charging requirements of these batteries (specified as 14.2 amps for a minimum time) since the charger does not bulk charge using time limits. Only incoming AC amps appear to be programmable and the charger remains in bulk stage until the acceptance voltage is achieved. Have searched through the Outback forums trying to learn how these chargers work and still haven't gained much confidence about the bulk stage. Any ideas or suggestions about this?
