The invention belongs to the technical field of batteries, and in particular relates to battery encasing equipment. The battery encasing equipment comprises a computer, and an electronic scale, a scanning gun and a printer which are respectively electrically connected with the computer, wherein the computer, the electronic scale, the scanning gun and the printer are respectively connected with a power supply. Compared with the prior art, the battery encasing equipment disclosed by the invention integrates the computer, the scanning gun, the electronic scale and the printer into a whole; the scanning gun scans outer codes, the electronic scale weighs the batteries; when the scanning gun finishes scanning, the printer automatically starts to print battery bar codes, case number and product weight; and in this way, production manpower is saved, waste is reduced, cost is lowered, and the problems that the case number is not consistent with the number on the encased batteries and the number of the encased batteries is excessive or insufficient are prevented. Simultaneously, the invention also discloses a battery encasing method using the equipment.
