Power Batteries

A Green Lantern must recharge their Lantern Power Ring periodically. This goes for all other Lantern Corps. Each Lantern has a Power Battery sized and shaped like an old fashioned lantern, which they can use to recharge their ring. These smaller Power Batteries are linked to the Central Power Battery which is the source of their power. Unlike the ring, Power Batteries do not need to be recharged.

Central Batteries

Each of the smaller, personal power batteries must link up to a central power source known as the central power battery. Each Corps maintains its own central power battery to channel its own specific power to the smaller power batteries.

Green Lantern Central Battery - Located on Oa, the planet in the center of the universe and the home base of the Green Lantern Corps, the Green Lantern Central Power Battery channels the same energies that the Guardians Of The Universe hold. This power battery is heavily protected, and has been used in the past to imprison powerful enemies of the Corps such as the demon Parallax and the rogue Green Lantern Sinestro.

Sinestro Corps Central Battery - The Sinestro Corps (Yellow Lantern Corps) Central Power Battery was originally located on the man planet of the Anti-Matter universe, Qward. During the Sinestro Corps War this power battery was teleported into the sentient planet Warworld for the primary attack on Earth. Warworld was destroyed when it was hurled into the Anti-Monitor. It is unknown if the yellow central battery was destroyed in the resulting explosion, however there are still yellow rings dispersed throughout the galaxy. If they are not drawing their power from this central battery it is probably safe to assume that there is another central battery somewhere, perhaps on Qward.

Black Lantern Central Battery - The exact location of the Black Lantern Corps Central Battery is unknown. When the Anti-Monitor was hurled away from Earth by Superman Prime at the end of the Sinestro Corps War he eventually crash-landed on a dark, barren planet far from Earth. In his weakened state he was unable to stop the closing of the ground around himself which formed the shell of the Black Lantern Central Power Battery. It is the Anti-Monitor's own power that supplies the power to this Black central battery for the Black Lantern Corps.

Other Batteries

Manhunters - The Manhunters were the Guardians of the Universe's first attempt at an interstellar police force. The Manhunters were powerful robots, but lacked the qualities that other sentient beings share which makes the Green Lanterns what they are. The Manhunters were built with the equivalent of a Green Lantern Power Battery in their heads, linking them to their power source at the Central Power Battery and eliminating their need to recharge. The Manhunters have since joined forces with the Sinestro Corps, and now have Yellow Power Batteries inside their heads, and are instead linked to the Yellow Lantern Central Battery. Functionally, the Power Battery in the Manhunters heads works very similar to a standard Battery, and has been used in the past to recharge both Green Lantern power rings and Yellow Lantern power rings.

Alpha-Lanterns - The Alpha Lanterns were created by the Guardians using similar technology to the Manhunters, however the Alpha-Lanterns are build from the living bodies of Green Lanterns. Similar to their predecessors, the Alpha-Lanterns have the equivalent to a Green Lantern Power Battery in their chests, giving them a link directly to the Central Battery on Oa and eliminating the need for them to recharge.
