Abstract
A battery check device for checking a battery of a camera having at least a storoboscopic flash unit is disclosed, which functions to compare a first reference time with a charging time of a main capacitor of the flash unit and, when the charging time becomes longer than the reference time, to indicate it as showing a considerable consumption of the battery. The device may have a second reference time which is longer than the first reference time so that the battery is disconnected from the flash unit when the charging time is longer than the second reference time. Thus, the battery can be checked even during a usage of the flash unit and prevented from being discharged completely.
