充電(dian)電(dian)池(chi)簡(jian)介

充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)，是充(chong)(chong)電(dian)(dian)(dian)次數有限的(de)可充(chong)(chong)電(dian)(dian)(dian)的(de)電(dian)(dian)(dian)池(chi)，配(pei)合充(chong)(chong)電(dian)(dian)(dian)器使用(yong)。市場(chang)上一(yi)般賣5號(hao)(hao)、7號(hao)(hao)，但是也有1號(hao)(hao)。充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)的(de)好處(chu)是經濟、環保(bao)、電(dian)(dian)(dian)量足、適合大(da)功率、長(chang)時間使用(yong)的(de)電(dian)(dian)(dian)器(如(ru)隨身聽(ting)、電(dian)(dian)(dian)動(dong)玩具等)。充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)壓比型號(hao)(hao)相同的(de)一(yi)次性電(dian)(dian)(dian)池(chi)低，AA電(dian)(dian)(dian)池(chi)(5號(hao)(hao)充(chong)(chong)電(dian)(dian)(dian))是1.2伏，9V充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)實(shi)際上是8.4伏。

充(chong)電電池選購

首先，我們要大致了(le)解電池(chi)的(de)容(rong)量和種(zhong)類(lei)。目(mu)前市面(mian)上的(de)充電電池(chi)因容(rong)量不同，充電后使(shi)用時(shi)間長短也(ye)不一。例如(ru)常用的(de)五號電池(chi)（ＡＡ型），市面(mian)上就有７種(zhong)類(lei)型，分別(bie)為500MAH、600MAH、700MAH、800MAH、850MAH、1000MAH及1200MAH。他們形狀大小是一致的(de)，差別(bie)在于容(rong)量不同。為了(le)使(shi)用方便，最(zui)好(hao)選(xuan)購容(rong)量較為大些(xie)的(de)電池(chi)。

其次(ci)，我們要根據它(ta)的(de)價(jia)格(ge)及品牌靈活(huo)的(de)辨別電(dian)池的(de)真偽。市面上假(jia)冒(mao)(mao)電(dian)池一類是(shi)由普通(tong)電(dian)池仿冒(mao)(mao)的(de)，為了(le)吸引消費者(zhe)，價(jia)格(ge)一般低于正常價(jia)，大都不能(neng)充(chong)(chong)電(dian)或者(zhe)只能(neng)充(chong)(chong)幾次(ci)電(dian)。這(zhe)類假(jia)冒(mao)(mao)電(dian)池識別方法很簡單，只需用萬用表檢測其電(dian)壓是(shi)否為1.5V即可，而真正的(de)充(chong)(chong)電(dian)電(dian)池是(shi)1.2V的(de)。
