I own several SONY devices and had been with Originalakku`s no problems, not even with the battery supplied to the DSC HX5V NP-BG1, which, however, not the remaining time in minutes anzeigt.Der NP-FG1 reached despite repeated loading (same number as BG1) not its Kapazität.Der charging is significantly earlier than indicated abgeschlossen.Entweder the battery is defective, or it needs some loads more to reach its full capacity.
