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.
- ‘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.’
- ‘And nobody wants a basement full of lead-acid batteries to smooth the electrical load.’
- ‘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.’
- ‘The lead-acid battery, invented by Planté in 1859 and further improved by Fauré in 1881, is the most widely used secondary battery.’
- ‘For example, here's what happens in one cell of a car's lead-acid battery.’
- ‘Fifty 12-volt lead-acid batteries were placed in the battery tray (two sets of 25 to create 300 volts DC).’
- ‘The minister named the products as beer, biscuits, cattle feeds, compound fertilisers, household and dishwashing liquid detergents and lead-acid starter batteries.’
- ‘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.’
- ‘Lead is used to make lead-acid storage batteries, ammunition, and cable coverings.’
- ‘This was, however, still an electric car, powered by heavy lead-acid batteries.’
- ‘For electricity he used a deep-cycle lead-acid battery which he charged by a variety of means.’
- ‘Therefore, an electric car has a normal 12-volt lead-acid battery to power all of the accessories.’
- ‘The largest use of lead is in the manufacture of lead-acid storage batteries.’
- ‘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.’
- ‘The car is powered by 52 lead-acid car batteries which produce 600V DC output.’
- ‘The system is powered by lead-acid batteries connected to a custom build switching regulator providing 12V and 5V.’
- ‘Electric vehicles using lead-acid batteries have been around a long time, notably in milk floats in many cities in the last 40 years.’
- ‘Lithium is the lightest metal on the Periodic Table, in contrast to lead in lead-acid batteries, which is one of the heaviest.’
- ‘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).’
- ‘It is powered by lead-acid batteries and can accelerate to just four knots.’
