置。[Scope of Claim for Utility Model Registration] a. Check signal output means for outputting a check signal; b. Voltage detection means for detecting battery voltage when the check signal is input; c. Voltage detected by the voltage detection means. a comparison means for comparing with a set reference voltage; d) controlling the signal output means to output a check signal, receiving the comparison result from the comparison means, and immediately when the detected voltage is higher than the reference voltage; If it is determined that the voltage is appropriate and the detected voltage is lower than the reference value, the check signal is output again.
A battery check device comprising: an appropriate/inappropriate judgment means for determining that the voltage is "inappropriate" when the voltage is continuously low for a predetermined number of times.
