The battery lasts tidy, subjectively longer than the Sony HX9V Standardakky my. Unlike the standard battery gives Display A minutes. Although is very different depending on whether you precisely makes videos, shoot photos or just look but provides a significantly better prognosis than the rest of the time as the few bars that one has with the "normal battery".
Sony, why only do you manage not settle this battery as standard your cameras. The few cents extra costs should be genuine but still in there ... A pity.
