The 20Ah rate is the standard rate for measuring Ah in a SLA, AGM and Flooded battery although it is not the only one. There is a 5Ah rate and 100Ah rate. You will typically see them on spec sheets for these types of batteries. Basically the 225Ah is the amperage of the battery. You can disregard the 20Ah rating.
