A method for inspecting a battery for short circuit includes: adjusting batteries, which have been subjected to initial charging and subsequent charging and discharging, to a first device voltage; measuring a pre-leaving voltage; leaving the batteries for a leaving period with terminals in an open state; measuring a post-leaving device voltage; actually measuring an actual measured voltage drop rate; determining whether or not each voltage is short-circuited; and, prior to the determining, estimating an estimating voltage drop rate according to an elapsed time and a leaving period. In the determining, it is determined whether or not each battery is short-circuited using the actual voltage drop rate and the estimated voltage drop rate.
