A method for assembling groups of electrical pole of batteries and battery product relate to technique of producing battery and products. In incldues steps of spreading cream, solifying and assembling, also step of match up procedure. Polar plate is folded as well as the positive polar plate and negative polar plate are allocated alternately. A polar plate is inserted into folded part of plate with opposite polar. The separating plate is installed between positive and negative plate. The invention raises producting efficiency, reduces rejection ratio. Since the polar plate is an integral, reliable connection reduces electrical resistance so as to increase effect of discharging large current.
