Might want to dial that back a bit. Since 12V/7ah batteries are mentioned I am assuming standard small gelcell units.
Proper float voltage for a deep cycle is lower than a SLI type, and gellcell even lower. Generally 13.6 - 13.8 would be the gellcell range, with 13.6 being right on for long life use of _small_ batteries. Equalizing charge wold be 14 - 14.2. Floating a small gelcell at 13.6 (27.2) v.s. 14 can mean the diff between 12 - 24 months v.s. 5 - 7 years service life.
