6 FAQs about [Lead-acid battery charge and discharge curve]

What is the ideal discharge curve of a lead acid battery?

The ideal discharge curve of a lead acid battery is on a flat discharge curve, the amount of current that the battery can deliver remain more or less constant for quite a while and then drop off rapidly when the limit of it capacity has been reach.

How many volts can a lead acid battery discharge?

The minimum open circuit voltage of a 12V flooded lead acid battery is around 12.1 volts, assuming 50% max depth of discharge. How much can you discharge a lead acid battery?

What happens when a lead acid battery is fully discharged?

In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery's state of charge. The dependence of the battery on the battery state of charge is shown in the figure below.

How deep should a lead acid battery be discharged?

Many lead acid batteries can only be discharged up to 50%. Discharging them more can cause permanent damage. You should never completely discharge a lead acid battery to 100% depth of discharge. Doing so can shorten its lifespan greatly.

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 is a lead acid battery?

Lead acid battery is the first secondary battery that has been invented by Gaston Planté in the year 1859 [3, 4]. A lead acid cell consists of two plates, which are a positive plate that made of lead antimony alloy grids coated with lead oxide (PbO 2 ) and a negative plate that made of spongy lead (Pb) .
