The time it takes to discharge a sealed lead-acid battery can vary depending on the load and the battery’s capacity. It is important to monitor the battery’s voltage during the discharge process to ensure that it does not drop below the recommended threshold.
The following graph shows the evolution of battery function as number of cycles and depth of discharge for a shallow-cycle lead acid battery. A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%.
When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
The nominal capacity of sealed lead acid battery is calculated according to JIS C8702-1 Standard with using 20-hour discharge rate. For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.
A lead acid battery is considered fully charged when its voltage level reaches 12.7V for a 12V battery. However, this voltage level may vary depending on the battery’s manufacturer, type, and temperature. What are the voltage indicators for different charge levels in a lead acid battery?
Batteries after long period storage will lose some capacity due to self-discharge, and need recharge to restore its full performance. Do not put sealed lead acid batteries in airtight containers, or install the batteries in a room without ventilation.
Constant current discharge curves for a 550 Ah lead acid battery at different discharge rates, with a limiting voltage of 1.85V per cell (Mack, 1979). Longer discharge times give higher battery capacities.
