6-volt (left) and 4.5-volt (right) lantern batteries. A lantern battery is a rectangular battery, typically an alkaline or zinc–carbon primary battery, used primarily in flashlights or lanterns. Lantern batteries are physically larger and consequently offer higher capacity than the more common flashlight batteries.
3LR12 (4.5-volt), D, C, AA, AAA, AAAA (1.5-volt), A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 (1.5-volt) batteries (Matchstick for reference). This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use.

[6] Generac's power systems range in output from 800 watts to 9 megawatts, [7] and are available through ...
A mechanically powered flashlight (UK: mechanically powered torch) is a flashlight that is powered by electricity generated by the muscle power of the user, so it does not need replacement of batteries, or recharging from an electrical source. There are several types which use different operating mechanisms.
Eveready Battery Company, Inc. is an American manufacturer of electric battery brands Eveready and Energizer, owned by Energizer Holdings. Its headquarters are located in St. Louis, Missouri. [1] The predecessor company began in 1890 in New York and was renamed in 1905.
An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. [12] The voltage of the battery declines steadily during use, so the total usable capacity depends on the cutoff voltage of the application.
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
