PURPOSE:To easily manufacture a sealed nickel-hydrogen battery having a highly efficient discharge capacity at low cost by holding the battery for a determined time at a specified temperature after conducting charge and discharge in forming process. CONSTITUTION:In the manufacture of a sealed nickel-hydrogen battery, after the battery is charged and discharged at least once in the forming process, the battery is held at a temperature of about 30-60 deg.C for a determined time, preferably, at least for 48-6 hours. Thereafter, the battery is finally charged. Thus, a high discharge capacity can be provided even at a high discharge ratio of about 1C or more, and a sealed type nickel-hydrogen battery having a highly efficient discharge capacity in which a high capacity can be obtained from sudden discharge in the initial stage can be provided. |
