InfoLithium: All Sony InfoLithium batteries incorporate an IC chip that communicates with the camcorder to provide the amount of time remaining on the battery. This feature is known as the Accu-Power metre and the battery time remaining is displayed in the viewfinder or LCD.
Lithium-Ion: Lithium-ion batteries provide superior ease of use and recording time when compared to Nickel-Cadmium (Ni-Cad) batteries. Unlike Ni-Cad batteries, you can recharge them at any time without developing any memory effect.
ActiForce: ActiForce is a new generation power system, which gives you better battery capacity, boost charge, and speed and accuracy of battery time remaining calculations, compared with the InfoLithium "P-series" batteries.
Compatibility: The NP-FH70 can be used with select Sony HandyCam camcorders with "H-Series" battery packs. It is also compatible with camcorders that use the "P-Series" InfoLithium batteries.
