This battery, introduced in 1901, was very common in continental Europe until the 1970s. It usually contains three B cells in series. In Switzerland as of 2008, 4.5-volt batteries account for only 1% of primary battery sales. [89] PP3, 9-volt, or E [90] Radio battery Smoke alarm battery Square battery Transistor battery 006P MN1604
A Li-ion 1.5V AA-size battery, sold by the Chinese company Kentli as "Kentli PH5" since 2014 and with similar batteries later available from other suppliers is a AA-sized battery housing containing a rechargeable 3.7 V Li-ion cell with an internal buck converter at the positive terminal to reduce the output voltage to 1.5 V. [18] The Kentli ...
Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. The long history of disposable dry cells means that many manufacturer-specific and national standards were used to designate sizes, long before international standards were reached.
During World War II, it was designated the Type C battery by the U.S. Navy, leading to confusion with the smaller C cell battery (BA-42). In 2007, D batteries accounted for 8% of alkaline primary battery sales (numerically) in the U.S. In 2008, Swiss purchases of D batteries amounted to 3.4% of primary and 1.4% of secondary (rechargeable) sales ...
The 1991 battery Directive's "Article 3; MI; Annex I" stated the prohibition (with exceptions) of marketing: Batteries on the market after 18 September 1992 with: 1.A. more than 25 mg of mercury per cell, except alkaline manganese batteries; 1.B. more than 0.025% cadmium by weight; 1.C. more than 0.4% lead by weight
In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready.

This requires temperatures of 800 °C (1,470 °F). One report estimated possible efficiency at around 65%. Although ionic aluminium oxidizes in the presence of air, this costs less than 1% of the energy storage capacity. [3] Discharging the battery involves oxidizing the aluminium, typically with water at temperatures less than 100 °C.
In 1971, a council of ministers was formed in the Abu Dhabi emirate by virtue of the provisions of Law No. (1) to reorganise the government apparatus. But in 1974, the said law was superseded and substituted with Law No. (1), which organised Abu Dhabi's government apparatus, renaming the "Council of Ministers" as the "Abu Dhabi Executive Council".
