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.

View more6 FAQs about [How to calculate the capacity of lead-acid valve-regulated batteries]
Is a lead-acid battery a primary battery?
PRIMARY BATTERY — A battery that can store and deliver electri-cal energy but cannot be recharged. A lead-acid battery is NOT a primary battery. RESERVE CAPACITY RATING — The time in minutes that a new, fully charged battery will deliver 25 amperes at 27°C (80°F) and maintain a terminal voltage equal to, or higher than, 1.75 volts per cell.
How is battery capacity calculated?
The system’s capacity is calculated after the completion of the test using the published performance data at 77°F. This method is recommended for test over 1 hour. Ta Ts Kt Example: An AGM-300 battery is rated to deliver 104Amps for 5 hours (300 minutes) to 1.75Vdc at 77.
What is battery capacity?
CAPACITY — The capacity of a battery is specified as the number of Amp-Hrs that the battery will deliver at a specific discharge rate and temperature. The capacity of a battery is not a constant value and is seen to decrease with increasing discharge rate.
How to test battery capacity?
This document is intended to simplify and condense the IEEE document into a helpful guide to testing battery capacity. Capacity tests should be carried out in accordance with IEEE-1188. Discharge tests should be performed between 65°F and 90°F. An equalize charge should be completed. 72 hours at 2.40vpc is recommended by SBS.
What happens when a lead acid battery is discharged?
The process is the same for all types of lead-acid batteries: flooded, gel and AGM. The actions that take place during discharge are the reverse of those that occur during charge. The discharged material on both plates is lead sulfate (PbSO4). When a charging voltage is applied, charge flow occurs.
What happens if a VRLA battery loses its capacity?
The capacity is lost and can only be restored by slowly discharging completely (generally outside the application), and properly recharging. VRLA batteries do not exhibit this “use it” or “lose it” capacity robbing effect known as memory.
