What is the discharge curve of a lead-acid battery?
The lead-acid battery discharge curve equation is given by the battery capacity (in ah) divided by the number of hours it takes to discharge the battery. For illustration, a 500 Ah battery capacity that theoretically discharges to a cut-off voltage in 20 hours will have a discharge rate of 500 amps / 20 hours = 25 amps.
What is the discharge rate of a lead-acid battery?
Sealed lead-acid batteries are generally rated with a 20-hour discharge rate. That is the current that the battery can provide in 20 hours discharged to a final voltage of 1.75 volts per second at a temperature of 25 degrees Celsius.
How to improve the discharge capacity of lead acid batteries?
The selective method to improve the discharge capacity is using high current pulses method. This method is performed to restore the capacity of lead acid batteries that use a maximum direct current (DC) of up to 500 A produces instantaneous heat from 27°C to 48°C to dissolve the PbSO<sub>4</sub> on the plates.
What happens when a lead-acid battery is discharged?
Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
How many Ah does a lead-acid battery provide?
It means that the 8.2 Ah lead-acid battery provides 1.64 A for 5 hours if discharged at 0.2C rate. The discharge current can be calculated using C-rated (C) rated capacity (Ah)/1 hour = current (A). , the battery voltage decreases from 13.07 V to ... [...]
How does specific gravity affect a lead-acid battery?
The specific gravity decreases as the battery discharges and increases to its normal, original value as it is charged. Since specific gravity of a lead-acid battery decreases proportionally during discharge, the value of specific gravity at any given time is an approximate indication of the battery’s state of charge.
