Power Battery
Every ring needs its charger.
The story
A Green Lantern typically recharges a standard ring at a personal power battery, a hand-held lantern linked to the Central Power Battery on Oa. Some stories give a charge roughly 24 hours, and using the ring can run it down. A Lantern traditionally recites the oath while recharging. Jo Mullein’s experimental ring recharges on its own.
Each Corps has its own batteries, shaped by its own emotion. The Sinestro Corps charges from yellow batteries fed by the fear harvested across the universe. The Red Lanterns' batteries sit in the Blood Ocean of Ysmault, steeped in rage. The Blue Lanterns' batteries on Odym glow with hope; the Orange Battery on Okaara with avarice; the Indigo Tribe's staffs with compassion. The design differs, but the principle is constant: the battery is the well, the ring is the cup, and the emotion is the water.
The battery is also a Lantern's greatest vulnerability. Destroy a sector's batteries and its Lanterns are stranded with dying rings — a tactic enemies have exploited across the Corps' history. And the oath itself is bound to the charging: "In brightest day, in blackest night..." — the words are the key that opens the flow. A Lantern who cannot speak the oath, or will not, cannot recharge. The battery gives power; the oath gives purpose. Read the words themselves on the quotes page.
