One of the mysteries of the English language finally explained.
Denoting a secondary cell or battery in which the electrodes are plates or grids of lead (or lead alloy) immersed in dilute sulphuric acid. The anode is coated with lead dioxide and the cathode with spongy lead.
- ‘Fifty 12-volt lead-acid batteries were placed in the battery tray (two sets of 25 to create 300 volts DC).’
- ‘Unlike automobiles, tractors depend on weight for traction, thus heavy, deep-cycle, lead-acid batteries that are inexpensive, recyclable and long-lived can be used to great advantage in an electric tractor.’
- ‘For electricity he used a deep-cycle lead-acid battery which he charged by a variety of means.’
- ‘According to answers to written questions, the ministry has approved for export over the last 3 years quantities ranging from 200 to 2,500 tonnes of lead-acid batteries a year to that plant.’

- ‘This was, however, still an electric car, powered by heavy lead-acid batteries.’
- ‘Therefore, an electric car has a normal 12-volt lead-acid battery to power all of the accessories.’
- ‘The manufacturer claims that eight hours of direct sunlight charges the 12-volt lead-acid battery enough to cut grass for nearly two hours with the power of a four-horsepower gasoline mower.’
- ‘They have a limited capacity (a typical lead-acid battery pack might hold 12 to 15 kilowatt-hours of electricity, giving a car a range of only 50 miles or so).’
- ‘And nobody wants a basement full of lead-acid batteries to smooth the electrical load.’
- ‘It is powered by lead-acid batteries and can accelerate to just four knots.’

- ‘Electric vehicles using lead-acid batteries have been around a long time, notably in milk floats in many cities in the last 40 years.’
- ‘Instead of three conventional lead-acid batteries, as installed by the manufacturer, the vehicle is now powered by a hybrid drive consisting of a fuel cell and a lithium-ion battery.’
- ‘The lead-acid battery, invented by Planté in 1859 and further improved by Fauré in 1881, is the most widely used secondary battery.’
- ‘The system is powered by lead-acid batteries connected to a custom build switching regulator providing 12V and 5V.’
- ‘Lead is used to make lead-acid storage batteries, ammunition, and cable coverings.’
- ‘The minister named the products as beer, biscuits, cattle feeds, compound fertilisers, household and dishwashing liquid detergents and lead-acid starter batteries.’
- ‘The car is powered by 52 lead-acid car batteries which produce 600V DC output.’
- ‘For example, here's what happens in one cell of a car's lead-acid battery.’
