A battery monitoring apparatus is for a vehicle including a battery and a starter for starting an engine thereof by using electric power supplied from the battery. The battery monitoring apparatus includes a current obtaining section that obtains, as a discharge current value, a value of a discharge current flowing out from the battery while the engine is being started, a current determination section that determines whether or not the discharge current value is smaller than a predetermined threshold value, a start determination section that determines whether or not the engine has been started up, and a jump-start determination section that determines that the engine has been jump-started if the discharge current value is determined to be smaller than the threshold value and the engine is determined to have been started up.
