Power is doubled through multiple power sources. One or two Li-Ion batteries (LP-E6 or HL-E6)* or 6 AA Mignon alkaline or rechargeable Ni-MH batteries can be used. This is especially useful when taking advantage of the camera's movie mode or LiveView mode.
Built-in Power Management regulates the power output to the camera for maximum efficiency. The Power Management detects use of Li-ion or AA batteries automatically.
