The faster you discharge a lead acid battery the less energy you get (C-rating) Recommended discharge rate (C-rating) for lead acid batteries is between 0.2C (5h) to 0.05C (20h). Look at the manufacturer’s specs sheet to be sure. Formula to calculate the c-rating: C-rating (hour) = 1 ÷ C
The fundamental approach involves understanding the nominal voltage and capacity of the battery. The formula for lead-acid battery kWh is: markdown kWh = Voltage x Capacity (in Ah) It’s crucial to consider the efficiency factor when calculating to enhance accuracy.
Formula: Lead acid Battery life = (Battery capacity Wh × (85%) × inverter efficiency (90%), if running AC load) ÷ (Output load in watts). Let’s suppose, why non of the above methods are 100% accurate? I won't go in-depth about the discharging mechanism of a lead-acid battery.
Figure 1: Typical discharge curve (voltage versus % charge) for a 24 volt lead acid battery. For the 24V lead acid battery example shown in figure 1, a battery which is 100% charged will have an output voltage of around 25.6 volts. At 50% charged stage, the output voltage of the battery is around 24V.
For the 24V lead acid battery example shown in figure 1, a battery which is 100% charged will have an output voltage of around 25.6 volts. At 50% charged stage, the output voltage of the battery is around 24V. Once the battery is 30% discharged, the discharge rate of the battery picks up sharply to a complete discharge.
Depth of discharge, representing the percentage of a battery’s capacity used, directly influences kWh calculations. Deeper discharges may lead to a shorter battery lifespan. Optimal kWh calculations consider the balance between extracting energy and preserving battery health. Utilizing Monitoring Systems
