It is a battery that many put in remote controls and/or something that is used for flashlights. The usual zinc-carbon battery consists essentially of one Zinkcup in which a thickened Salmiaksevering (NH4Cl) and Braunstein (MnO2) are filled. The thickened pulp - called the Battery hence dry battery - is a charcoal pencil. The voltage of a fresh Zn-C cell is 1.5 V.

Why is it possible for alkaline batteries to be smaller than zinc-carbon dry cells?
A battery can actually be made into any size, but very small batteries would be drained in a matter of seconds and are thus useless. Since zinc-carbon batteries contain less electrical energy per volume compared to an alkaline battery they are normally used for the larger sizes of batteries. Rayovac has published a graph where the zinc-carbon and alkaline batteries have been compared. It shows that the alkaline battery works just as good after 17 hours of use as the zinc-carbon battery does after only 8 hours of use. (http://www.rayovac.com/technical/pdfs/pg_battery.pdf) Eurobatt claims that alkaline batteries can have 4-15 times longer lifetime than the zinc-carbon type. But it isn't mentioned under what type of conditions this is. (http://www.eurobatt.net/index7201.html?page=213&l=1)
Uses of zinc?
Zinc is an important ingredient in traditional dry cell batteries and is also widely used to cover steel to reduce corrosion of the steel by sacrificial corrosion of the zinc instead. The latter effect may be achieved by cathodic protection as well as by direct contact between steel and zinc.
Are sunbeam batteries alkaline based?
Sunbeam offers both alkaline and carbon-zinc (super heavy duty) versions of their batteries. Alkaline are ideal for higher drain devices such as wireless video game controllers and computer peripherals, radios and certain toys. Carbon-zinc batteries are designed for low drain applications such as remote controls, smoke detectors and clocks.
Disadvantages of carbon zinc batteries?
Short shelf life,low capacity leakage when empty.Advantages:low cost low unit weight.
What grey metal is used to galvanise iron and is also found in torch batteries?
This metal is lead (Pb).
Are batteries made with iron?
No. Lead-acid batteries are made using lead which is immersed in an acid, usually sulfuric. Carbon batteries have a carbon rod core with zinc and copper. NiCad batteries are similar to carbon batteries, but a nickle-Cadmium rod are used. Lithium batteries are similar as well, but lithium is used.
What is difference between lr20 and r20 batteries?
R20 are zinc-carbon batteries, whereas LR20 are alkaline batteries.
What are some uses for carbon rods from batteries other than batteries and arc lamps?
Unfortunately modern batteries do not have carbon rods. To prevent punch through leaks from the zinc can, the carbon has been moved to a coating on the inside of a steel can and the zinc has become a finned metal rod in the center.

What batteries contain Mercury?
Originally mercury was amalgamated with the zinc in carbon-zinc dry cell batteries because the zinc was contaminated with tiny iron granules. As the zinc corroded away in the electrochemical process of the battery producing electric current these iron granules would surface and become exposed to the electrolyte producing local shorted iron-zinc "batteries" that would cause the zinc to rapidly corrode through and the battery to leak electrolyte out its side through these holes. The mercury added to the zinc would envelope these iron granules, preventing them from contacting the electrolyte and thus greatly extending battery life. When alkaline dry cell batteries replaced the original acid carbon-zinc dry cell batteries, as they were still using carbon and zinc electrodes mercury was still amalgamated with the zinc to extend battery life as the zinc was still contaminated with tiny iron granules. However when it became a priority for dry cell companies to eliminate toxic materials like mercury from their batteries, the solution was to use more expensive high purity zinc with lower iron contamination levels so that less mercury would be needed. As the goal is to eventually completely eliminate all of the mercury, it will eventually be necessary for them to use zinc that is completely iron free. An entirely different class of batteries, the mercuric oxide-zinc battery and the mercuric oxide-cadmium battery used mercuric oxide for one of the electrodes. Such batteries offered many advantages over carbon-zinc (both acid and alkaline versions) batteries and were widely used from 1942 until 1992 and were ultimately banned by 1996.
What is one of the chemicals in a battery?
This varies depending on the specific battery "chemistry" used.the old carbon-zinc batteries used - carbon, zinc-mercury alloy (with iron grains contamination in the zinc), zinc chloride paste, water, manganese dioxide (to suppress hydrogen gas formation), porous paper separatormodern alkaline batteries use - carbon, zinc, potassium hydroxide paste, water, manganese dioxide (to suppress hydrogen gas formation), porous paper separatorlead-acid batteries use - lead, sulphuric acid, waternickel cadmium batteries - nickel oxide hydroxide, cadmium, potassium hydroxide paste, water, porous paper separatorlithium manganese batteries - lithium, manganese dioxide, lithium perchlorate paste, propylene carbonate, propylene dimethoxyethane, porous paper separatorlithium ion batteries - lithium nickel manganese cobalt oxide, carbon, lithium perchlorate paste, ethylene carbonate, porous paper separatoretc,

What kind of batteries were used in 1957 in Sputnik and how large were they?
silver-zinc
Nearly the last metallic element in the alphabet and used in batteries?
the answer is zinc
Can zinc make cans?
no. but tin (Sn) can make cans zinc is used to make dry cells or batteries
