  2. Battery leakage - Wikipedia

    en.wikipedia.org/wiki/Battery_leakage

    Battery leakage is the escape of chemicals, such as electrolytes, within an electric battery due to generation of pathways to the outside environment caused by factory or design defects, excessive gas generation, or physical damage to the battery.

  3. Dry cell - Wikipedia

    en.wikipedia.org/wiki/Dry_cell

    Dry cell battery by Wilhelm Hellesen 1890. Many experimenters tried to immobilize the electrolyte of an electrochemical cell to make it more convenient to use. The Zamboni pile of 1812 is a high-voltage dry battery but capable of delivering only minute currents. Various experiments were made with cellulose, sawdust, spun glass, asbestos fibers ...

    en.wikipedia.org/wiki/Duracell

    Typical Duracell 9V battery. Duracell Inc. is an American manufacturer of alkaline batteries, specialty cells, and rechargeables; it is a wholly owned subsidiary of Berkshire Hathaway since 2016. The company has its origins in the 1920s, through the work of Samuel Ruben and Philip Mallory, and the formation of the P. R. Mallory Company.

  5. Nickel–metal hydride battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–metal_hydride_battery

    A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.

    Another problem with Volta's batteries was short battery life (an hour's worth at best), which was caused by two phenomena. The first was that the current produced electrolyzed the electrolyte solution, resulting in a film of hydrogen bubbles forming on the copper , which steadily increased the internal resistance of the battery (this effect ...

    The company registered its "Duracell" trademark in 1964 and began rebranding under the new name with the intent of marketing directly to consumers instead of industrial and military customers. [1] In 1978, the company was purchased by Dart Industries and renamed Duracell after its alkaline battery brand. In 1985, the European metal alloys parts ...

  8. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    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 terminal marked negative is the source of electrons.

    I've added the battery size (AA), and changed the 33 ohm to 330 mW. Without the full context the 33 ohm made no sense (the battery was powering a boost converter, and the 33 ohm load was connected to the output of the converter, not to the battery). At 1.5V, a 33 ohm load would only draw 68mW. Prevalence 19:59, 12 May 2019 (UTC)
