A couple points...
The loss of shore power might induce a ABSORB/BULK charge running closer to 14.4V. Depending on the battery profile, the time it is in bulk could be a couple hours which the user determines via the SET ABSORB TIME DONE setting. After that it should FLOAT for about 4 hours then into a NO CHARGE for a period of time. The actual times and voltages are determined by the battery profile selected so they could be different by a little bit from what I see with my Life Line AGMs. They will also be affected by the BTS reading. If there is no BTS then the remote assumes it is 72* which can result in under charging in colder weather and over charging in hotter weather.
The Magnum should NOT go through an equalization charge unless specifically called for by the user via the remote control.
Per the table for the ME-ARC charging voltages the highest voltage for any battery for a given charge state are:
BULK/ABSORB - 14.6V
FLOAT - 13.6V
EQUALIZATION - 15.5V
