I would like to fit a different AGM battery

For systems using the PX300 charger (EC400/EC400+, EC500, EC600, EC700, EC800, & EC328):

Whilst we do not recommend any specific make or model of battery, the PX300 charger used in these systems is compatible with the majority of good quality AGM batteries available in the UK.

The charge profile of the PX300 is shown in the instruction manual attached below.  If you are in any doubt as to the fitment of a battery you should confirm with the battery distributer / manufacturer that the PX300 charge profile is suitable.
