The auto industry uses over 1,000,000 metric tons (980,000 long tons; 1,100,000 short tons) of lead every year, with 90% going to conventional lead–acid vehicle batteries. While lead recycling is a well-established industry, more than 40,000 metric tons (39,000 long tons; 44,000 short tons) ends up in landfills every year. According to the ...
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.
Batteries use 85% of the lead produced worldwide and recycled lead represents 60% of total lead production. Lead–acid batteries are easily broken so that lead-containing components may be separated from plastic containers and acid, all of which can be recovered.
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.
In 1992 about 3 million tons of lead were used in the manufacture of batteries. Wet cell stand-by (stationary) batteries designed for deep discharge are commonly used in large backup power supplies for telephone and computer centres, grid energy storage, and off-grid household electric power systems.
Lead–acid batteries typically have coulombic (Ah) efficiencies of around 85% and energy (Wh) efficiencies of around 70% over most of the SoC range, as determined by the details of design and the duty cycle to which they are exposed. The lower the charge and discharge rates, the higher is the efficiency.
The use of lead acid battery in commercial application is somewhat limited even up to the present point in time. This is because of the availability of other highly efficient and well fabricated energy density batteries in the market.

Although lead-acid batteries are 99% recyclable, lead exposure can still occur during the mining and processing of the lead, as well as during the recycling process. Lithium-ion batteries, on the other hand, do not contain any toxic materials and are easier to recycle.

Number of watts per hour / .9 x number of hours of backup / .8. Example: 107W/h / .9 x 24 hrs / .8 = 2854 Watts, 238 AH @ 12V _____ But, it''s not quite that simple! [see Forum Thread this is taken from for more] The actual capacity of a lead acid battery, for example, depends on how fast you pull power out. The faster it is withdrawn the less efficient it is. For …
Stationary lead-acid batteries remain the economical first choice for standby power batteries with discharge times between 15min and 8h; they have been well proven in practice. The battery can be kept permanently on float in a fully-charged state, as long as both electrodes are in an electrochemical balance 1
In 2010, the estimated total global emissions were about 3.6 million tonnes (about 22 per cent from production, 13 per cent from use, and 65 per cent from waste management and recycling). These amounts are equal to more than 25 per cent of the total amount of lead produced from mining in the same year (Liang and Mao 2015).
The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO 4 – → PbSO 4 + H + + 2e – At the cathode: PbO 2 + 3H + + HSO 4 – + 2e – → PbSO 4 + 2H 2 O. Overall: Pb + PbO 2 +2H 2 SO 4 → ...

According to a 2003 report entitled "Getting the Lead Out", by Environmental Defense and the Ecology Center of Ann Arbor, Michigan, the batteries of vehicles on the road contained an estimated 2,600,000 metric tons (2,600,000 long tons; 2,900,000 short tons) of lead. Some lead compounds are extremely toxic. Long-term exposure to even tiny amounts of these compounds can cau…
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.
Lead−acid batteries are eminently suitable for medium- and large-scale energy-storage operations because they offer an acceptable combination of performance parameters at a cost that is substantially below those of alternative systems.
