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.
Battery voltage, or state of charge (SOC), of a lead-acid battery can be estimated by measuring the open (no load) battery terminal voltage using a digital voltmeter. Prior to measuring, the battery must have rested for 4 to 8 hours after charge or discharge and resided at a steady room temperature.
