The lead–acid batteries are both tubular types, one flooded with lead-plated expanded copper mesh negative grids and the other a VRLA battery with gelled electrolyte. The flooded battery has a power capability of 1.2 MW and a capacity of 1.4 MWh and the VRLA battery a power capability of 0.8 MW and a capacity of 0.8 MWh.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
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.
Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles. Batteries with tubular plates offer long deep cycle lives.

Domestic lead-acid batteries generally use a capacity with a constant current discharge time of 10 h (called a 10 h discharge rate) as the rated capacity, which is recorded as C10. Rated capacity can be understood as the maximum available capacity under rated conditions.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours ... (alkaline, lithium, lead acid, etc), often only the Amps*hour measurement is printed on the side, expressed in Ah or mAh (1000mAh = 1Ah). To get Wh, multiply the Ah by the nominal voltage. For example, lets say we have a 3V nominal battery …
The minimum capacity that a lead-acid battery should be able to discharge under the conditions specified in the design, such as temperature, discharge rate, termination voltage, etc., expressed in ampere hours and denoted by the symbol C. The capacity is greatly affected by the discharge rate, so the discharge rate is often indicated by Arabic numerals in the lower right corner of the …
