Max Discharge Current (7 Min.) = 7.5 A; Max Short-Duration Discharge Current (10 Sec.) = 25.0 A; This means you should expect, at a discharge rate of 2.2 A, that the battery would have a nominal capacity (down to 9 V) between 1.13 Ah and 1.5 Ah, giving you between 15 minutes and 1 hour runtime.
The C rating essentially denotes the maximum safe continuous discharge rate of a battery in relation to its capacity. For instance, if a battery has a capacity of 1000mAh and a C rating of 1C, it can be discharged at a continuous rate equal to its capacity (1000mA or 1A).
