An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2]
The nominal voltage of a fresh alkaline cell as established by manufacturer standards is 1.5 V. The actual zero-load voltage of a new alkaline battery ranges from 1.50 to 1.65 V, depending on the purity of the manganese dioxide used and the contents of zinc oxide in the electrolyte. The voltage delivered to a load decreases as the current drawn ...
0.1: 12.5 × 1.6 Used in some lighted watches and some LED decorator lights (electronic tea candles). CR1220: 5012LC: 35–40: 0.1 (CR) 0.03 (BR) 12.5 × 2.0 Used in keychain LED flashlights, and in some digital cameras to keep the time and date function running even when the main battery is taken out of the camera.

The Message: The Bible in Contemporary Language (MSG) is a paraphrase of the Bible in contemporary English. Authored by Eugene H. Peterson and published in segments from 1993 to 2002. [2] A Catholic version, The Message – Catholic / Ecumenical Edition, was published in 2013. [3]
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Lithium salt or a salt such as a tetraalkylammonium chloride dissolved in LiClO 4 in an organic solvent that is a mixture of 1,2-dimethoxy ethane, 1,3-dioxolane and 2,5-dimethyloxazole as a stabilizer [28] 1.5 V Li–PbCuS Lead sulfide and copper sulfide: 1.5 V 2.2 V Li–FeS Iron sulfide: Propylene carbonate, dioxolane, dimethoxyethane: 1.5 ...
2 MnO 2 + ZnCl 2 + H 2 O + 2 e − → Mn 2 O 3 + Zn(OH) 2 + 2 Cl −. giving the overall reaction Zn + 2 MnO 2 + H 2 O → Mn 2 O 3 + Zn(OH) 2. The battery has an electromotive force (emf.) of about 1.5V. The approximate nature of the emf is related to the complexity of the cathode reaction. The anode (zinc) reaction is comparatively simple ...
It provides a potential of 1.5 volts. The first mass-produced model was the Columbia dry cell, first marketed by the National Carbon Company in 1896. [ 15 ] The NCC improved Gassner's model by replacing the plaster of Paris with coiled cardboard , an innovation that left more space for the cathode and made the battery easier to assemble.
