To provide a battery type industrial vehicle capable of reducing occurrence frequency of a cut-off state of input/output due to temperature rise of a battery device, and allowing an operator to surely recognize that, a state almost becomes in a cut-off state due to temperature rise.SOLUTION: A battery type industrial vehicle comprises: a drive motor; a battery device for outputting power for driving the drive motor, and receiving power when the drive motor is caused to perform a regenerative operation; temperature detection means for detecting temperature of the battery provided on the battery device; and a controller for controlling the drive motor, in which the controller restricts an output of the drive motor according to temperature of the battery when temperature of the battery detected by the temperature detection means is equal to or greater than restriction start temperature T11, namely a state is a first high temperature state.SELECTED DRAWING: Figure 5
