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 torch batteries. Lantern batteries comprise multiple cells inside a housing.
The 6-volt variety typically has spring or screw terminals. Utilizing various internal construction styles, the same package size may be made up with "D" size or "F" size cells, offering various capacities. A rechargeable version, comprising a three-cell sealed lead-acid battery with a lower capacity than primary versions, has also been marketed. They are also used in the construction industry for powering flashing lights at roadworks.
More common in Europe and Russian Federation, this is a smaller, flat-pack battery mostly used in flashlights. It uses two metal strips as terminals. The shorter strip is the + terminal.
The 7.5-volt version has screw terminals and rectangular base. A carrying handle is usually connected between the terminals.
The 12-volt version has screw terminals and a rectangular base. Since it is 12-volt, this type can be used to power car accessories outside of an automobile, using extra wiring or an adapter.
