Battery Capacity
D oes it mean that I 0.25 (current of 1/4 hour discharge) equils C 20 x 4 ? No, it is not correct. Lead-acid battery capacity for 15-minute (1/4 hour) discharge usually is slightly less then half of C 20.That is why I 0.25 is not more then C 20 x2. As we see discharge current and discharge time ore not directly proportional.

About the Lead Acid Battery
Lead batteries operate in a constant process of charge and discharge When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery then begins to discharge. As a battery begins to discharge, the lead plates become more alike, the acid becomes weaker and the voltage drops.
