實用新型涉及電池充電裝置，包括外殼及內部的電源電路、熔斷絲、散熱裝置及線路板，在外殼面板上設有開關及顯示器，其中線路板由放電回路、充電回路、溫度保護回路、定時控制回路、記憶修復回路、強制充電回路組成，顯示器中設電源、放電、充電、充滿四個指示燈，外殼面板上還設有強制充電按鈕和記憶修復按鈕。本實用新型實現全自動先放后充、能夠恢復衰退容量，特別適合作為一種中功率鎘鎳電池組充電器。
    

近年來市場上出售的松下M9000攝像機電池，多數都是生產商用十節鎳氫電池串接組裝的，標稱12V 1.8Ah或12V 2.1Ah多種，但這種電池用攝像機原配充電器充電時電池會出現過熱（溫度會超過50℃），頻繁充電造成電池組過熱導致電解質快速分解揮發，使用壽命未到即造成電池組報廢，也經常出現充電后電量不足。
