You might want to be aware of what float voltage is required for any particular AGM battery you buy, as they don't all float at the same voltage. Actually, the float battery for any lead acid RV battery is temperature dependent, so AGM manufacturers sometimes publish a chart showing their recommended float voltages versus the temperatures you'll be camping in.
For instance: 12V Lifeline AGM batteries are to be floated (in nominal temperatures) at 13.2 volts to 13.4 volts, while 12V Rolls AGM batteries are to be floated (in nominal temperatures) at 13.5 volts to 13.8 volts.
If you want to keep your current charger, then you should pick an AGM battery that requires a float voltage that matches your charger's output voltage during float.
