Abstract
A method for recycling a battery pack is provided that enables a degraded battery pack to be replaced at a low cost while maintaining the advantages of a conventional sealed-type nickel-metal hydride secondary battery as being free from maintenance or leak of an electrolyte. The battery pack accommodates a battery module having a plurality of cells, which are a sealed-type nickel-metal hydride secondary battery, combined with each other. When the battery pack is judged as being degraded in a market, the battery pack is collected from the market as a battery to be replaced; a cell or battery module judged as being degraded is renewed by adding an electrolyte thereto; the battery module is installed in the battery pack again; and the battery pack is supplied as a replacement battery.
