It turns out that the usable capacity of a lead acid battery depends on the applied load. Therefore, the stated capacity is actually the capacity at a certain load that would deplete the battery in 20 hours. This is concept of the C-rate. 1C is the theoretical one hour discharge rate based on the capacity.
The lead acid battery is traditionally the most commonly used battery for storing energy. It is already described extensively in Chapter 6 via the examples therein and briefly repeated here. A lead acid battery has current collectors consisting of lead. The anode consists only of this, whereas the anode needs to have a layer of lead oxide, PbO 2.
The capacity of a lead–acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert's law.
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.
The lead-acid battery consists negative electrode (anode) of lead, lead dioxide as a positive electrode (cathode) and an electrolyte of aqueous sulfuric acid which transports the charge between the two. At the time of discharge both electrodes consume sulfuric acid from the electrolyte and are converted to lead sulphate.
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.

There are two general types of lead-acid batteries: closed and sealed designs. In closed lead-acid batteries, the electrolyte consists of water-diluted sulphuric acid. These batteries have no gas-tight seal. Due to the electrochemical potentials, water splits into hydrogen and oxygen in a closed lead-acid battery.
This article examines lead-acid battery basics, including equivalent circuits, storage capacity and efficiency, and system sizing. Stand-alone systems that utilize intermittent resources such as wind and solar require a means to store the energy produced so the stored energy can then be delivered when needed and the resources are unavailable.

Different battery chemistries have different discharge signatures, which can affect the accuracy of voltage-based SoC methods. To get accurate readings, the battery needs to rest in the open circuit state for at least four hours, although battery manufacturers recommend 24 hours for lead acid batteries.
VALVE REGULATED LEAD-ACID BATTERY (VRLA BATTERY) — A battery constructed with a fully enclosed case venting system sealed with a 1-way valve, under pressure above atmospheric, where venting of gasses is regulated through the valve that operates in a normally closed position. This configuration enables an oxygen charge shuttle reaction (recombination) inside the …
The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them. The most important lesson here is this:
Lead-acid batteries are reliable, with efficiency (65–80%) and good surge capabilities, are mostly appropriate for uninterruptible power supply, spinning reserve and power quality applications.

In the discharged state, both the positive and negative plates become lead(II) sulfate (PbSO 4), and the electrolyte loses much of its dissolved sulfuric acid and becomes primarily water. Negative plate reaction Pb(s) + HSO 4(aq) → PbSO 4(s) + H (aq) + 2e The release of two conduction electrons gives the lead electrode a negative charge. As electrons accumulate, they create an electric field which attracts hydrogen ions and repels s…
