The Shield Battery is a structure that restores Protoss Shields. While it was always part of the multiplayer in Brood War, it was only recently introduced to StarCraft II's multiplayer in Patch 4.0.0.
In multiplayer, the shield battery restores shields of a single friendly unit within 6 range. Shields restore at 50.4 shields per second, drains 1 energy for every 3 shields restored. This ability is autocast on friendly units and photon cannons.
Because of their low cost, Shield Batteries can be effective in supporting Carriers and Archons, both of which have many shield points. Due to lack of mobility, Shield Batteries are most useful when placed in direct support of a defensive position, such as at the top of a ramp the Protoss player is trying to defend.
