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。 
    

原充電器標稱充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)指標12V或14V電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)1.5A電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，只適用(yong)于免維護鉛蓄電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，對鎳氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)不(bu)適用(yong)，其原因是電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)過(guo)大、電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)偏低。這里介紹一種我去年制作(zuo)的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)，一年來一直(zhi)使用(yong)良好，專門(men)供幾種攝像機(ji)的鎳氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)數據：電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)容量(liang)跟(gen)(gen)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的比為(wei)10∶2，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)跟(gen)(gen)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的比為(wei)1∶1.5左右，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間為(wei)5小時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)足，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)亦無(wu)發熱現象(xiang)。
