Cyclic use is the use of a battery where the need to charge and discharge quickly. Standby use is where the battery is charged already and when needed it used. 0.1C means multiply 0.1 by the total capacity of the battery. If you have a 40Ah battery means 0.1C is 0.1 x 40 = 4A. Same for 0.25C = 0.25 x 40 = 10A.
