當你有了(le)充電電池(chi)，就(jiu)要開始為電池(chi)的充電而操心。由于(yu)各(ge)種原因，不(bu)是每個用(yong)戶都擁(yong)有原廠提供(gong)的充電器(qi)，出于(yu)價格(ge)等因素(su)，相(xiang)當一部分用(yong)戶都會去選購第三方提供(gong)的兼容充電器(qi)。我們在市(shi)場(chang)中可以看到形形色(se)(se)色(se)(se)各(ge)種外型和(he)價格(ge)檔次(ci)(ci)以及品牌的充電器(qi)。電池(chi)的使用(yong)壽命(ming)和(he)單次(ci)(ci)循(xun)環使用(yong)時間與充電維護過程和(he)使用(yong)情(qing)況密切相(xiang)關。

    選購充電器也要講究品牌，應該是正規廠家生產的商品。因為上面雖然介紹一些充電器的原理，但實際識別卻非常困難。即便是專業人士，在不打開充電器、不使用測試儀器的情況下，也很難從充電器外表準確判斷充電器的性能與質量。一些著名品牌的產品雖然價格會略高一些，但從線路設計到元件選用都比較正規科學，所以充電效果也比較理想。一般飛毛腿、世界通、勁牛、香山紅葉等品牌的產品比較有名。 在使用過程中我們也可以檢驗充電器的性能。在充電的后期電池有略微的溫升是正常現象，但如果電池明顯發燙，則說明充電器未能及時檢測到電池充電已飽和，造成過充，這對電池的壽命不利。很多充電器雖然沒有(you)(you)過充(chong)現象，但存在充(chong)電(dian)不足的問(wen)題，直接(jie)表(biao)現為電(dian)池(chi)放電(dian)時間短。 還要注意一點：充(chong)電(dian)過程中，電(dian)池(chi)和充(chong)電(dian)器嚴(yan)禁正負(fu)極接(jie)反(fan)，必(bi)須正極接(jie)正極，負(fu)極接(jie)負(fu)極。如(ru)果接(jie)反(fan)有(you)(you)可能造成短路(lu)或(huo)者爆炸(zha)，造成人身傷害。切記！ 鑒于以上所(suo)述，希望充(chong)電(dian)電(dian)池(chi)用(yong)戶盡(jin)量選用(yong)原裝配(pei)套充(chong)電(dian)器。
