（1）充電電池的容量

消費者要根據電(dian)(dian)器(qi)耗電(dian)(dian)量大(da)小來(lai)購買電(dian)(dian)池(chi)(chi)(chi)。電(dian)(dian)容量越(yue)大(da)的(de)電(dian)(dian)池(chi)(chi)(chi)，瞬間(jian)工(gong)作電(dian)(dian)流大(da)，因(yin)此對電(dian)(dian)器(qi)電(dian)(dian)路(lu)的(de)要求高，搞不好會燒壞電(dian)(dian)路(lu)。同時對電(dian)(dian)池(chi)(chi)(chi)自身的(de)損耗也(ye)大(da)。電(dian)(dian)容量大(da)的(de)電(dian)(dian)池(chi)(chi)(chi)，充電(dian)(dian)循環次數相對要少，也(ye)就是壽命相對較短。

因此，耗(hao)電(dian)(dian)量(liang)中等以下的(de)電(dian)(dian)器，如(ru)mp3、無線鼠(shu)標、小(xiao)型玩具(ju)、手電(dian)(dian)筒(tong)等，選(xuan)用(yong)1300-1800毫(hao)安時(shi)(shi)的(de)5號(hao)(hao)電(dian)(dian)池或(huo)者600-800毫(hao)安時(shi)(shi)的(de)7號(hao)(hao)電(dian)(dian)池就(jiu)可以，耗(hao)電(dian)(dian)量(liang)大的(de)電(dian)(dian)器，如(ru)相機、剃須(xu)刀、電(dian)(dian)動(dong)牙刷、話筒(tong)、玩具(ju)汽(qi)車、航模等，需要選(xuan)用(yong)2000-2600毫(hao)安時(shi)(shi)的(de)5號(hao)(hao)電(dian)(dian)池或(huo)850-1000毫(hao)安時(shi)(shi)的(de)7號(hao)(hao)電(dian)(dian)池。

（2）充電電池的自放電

充(chong)電(dian)(dian)電(dian)(dian)池(chi)放置一段時間(jian)后，電(dian)(dian)量(liang)會逐漸(jian)減(jian)少(shao)，稱(cheng)之為自放電(dian)(dian)。品質(zhi)不好的電(dian)(dian)池(chi)，自放電(dian)(dian)現象嚴重。這樣，為了滿(man)足使用，充(chong)電(dian)(dian)電(dian)(dian)池(chi)需(xu)要頻繁充(chong)電(dian)(dian)，從而(er)降(jiang)低了電(dian)(dian)池(chi)使用壽命。

低自放電(dian)充電(dian)電(dian)池也(ye)就應運而生(sheng)。品質優(you)異的低自放電(dian)電(dian)池，據說(shuo)放置2年后，還能保持80%以上的電(dian)量，大大方(fang)便(bian)了(le)消費者(zhe)的日常使(shi)用，也提高了(le)電(dian)池的使(shi)用周(zhou)期。當然，低自放電(dian)池的價格會高于普通充電(dian)電(dian)池。

如果使用充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)不是很頻(pin)(pin)繁(fan)，使用一次電(dian)(dian)(dian)池(chi)(chi)后會放(fang)置一段時間(jian)，建議考慮(lv)購買(mai)低自放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)。若使用充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)的頻(pin)(pin)率很高，購買(mai)普通(tong)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)就可(ke)以了。

（3）電池類型的選擇

如果需要(yao)為耗(hao)電(dian)(dian)(dian)(dian)(dian)量大的(de)(de)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)如相(xiang)機、玩具汽(qi)車(che)、剃須刀等購買(mai)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，建議(yi)考慮(lv)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)和堿性電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，這時最好不要(yao)貪便宜(yi)買(mai)碳(tan)性電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。對于(yu)耗(hao)電(dian)(dian)(dian)(dian)(dian)量低的(de)(de)遙控器(qi)(qi)、鐘表、收音機等，便宜(yi)的(de)(de)碳(tan)性電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)足夠。家里有終止電(dian)(dian)(dian)(dian)(dian)壓較高的(de)(de)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，推薦購買(mai)優質的(de)(de)堿性電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)或充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。

（1）充(chong)電(dian)電(dian)池到手后，需要反復充(chong)放3-4次(ci)，才能充分激活電(dian)池，達到最佳使用狀態。首(shou)(shou)次(ci)充電(dian)前(qian)，最好把余電(dian)用完，首(shou)(shou)次(ci)充電(dian)的時間可以(yi)比(bi)建議充電(dian)時間稍長。充電(dian)時最好一(yi)次(ci)性充滿(man)，不(bu)要(yao)充一(yi)下用一(yi)下又接著充。

（2）電(dian)池(chi)(chi)使(shi)用和充電(dian)時一(yi)(yi)定把正(zheng)負極對好，否則可能燒壞電(dian)池(chi)(chi)或者電(dian)器。不要嘗試給一(yi)(yi)次性電(dian)池(chi)(chi)充電(dian)。

（3）需要同時(shi)使(shi)用多(duo)節電(dian)池(chi)時(shi)，最好(hao)選擇容量和(he)狀態一致的(de)電(dian)池(chi)，道理和(he)短(duan)板效(xiao)應一致。例如，最好(hao)不同時(shi)使(shi)用1300毫安時和1800毫安時的電(dian)池(chi)，不同時使用新(xin)電(dian)池(chi)和老電(dian)池(chi)，否(fou)則將會降低(di)大容量電(dian)池(chi)或者新(xin)電(dian)池(chi)的效(xiao)用。

（4）充(chong)電(dian)時(shi)(shi)充(chong)電(dian)器和(he)電(dian)池發熱是正常(chang)的，所以(yi)充(chong)電(dian)時(shi)(shi)請注意(yi)周圍不要有(you)易燃易爆物品。如果充(chong)電(dian)器和(he)電(dian)池時(shi)(shi)過于(yu)發燙，可(ke)以(yi)先拔(ba)掉電(dian)源停止充(chong)電(dian)，等(deng)待溫度下降后，再充(chong)電(dian)。

（5）如果(guo)一(yi)段時間不使(shi)用(yong)(yong)電(dian)池(chi)，建議(yi)把(ba)電(dian)池(chi)拿出來，將電(dian)池(chi)和充(chong)電(dian)器(qi)放(fang)置在干燥地方存(cun)放(fang)，用(yong)(yong)電(dian)池(chi)盒存(cun)放(fang)電(dian)池(chi)最好。電(dian)池(chi)放(fang)置時注意(yi)不要短(duan)路(lu)(lu)，有個(ge)客戶曾經把(ba)電(dian)池(chi)和一(yi)大串鑰匙放(fang)在一(yi)起(qi)，結果(guo)導致(zhi)短(duan)路(lu)(lu)，電(dian)池(chi)損(sun)壞。

（6）從(cong)充電器里取放(fang)電池時，注意輕(qing)拿輕(qing)放(fang)。如(ru)果從(cong)充電器里野蠻地摳放(fang)電池，會很快損壞電池膠腸，影響電池壽命。這點KTV客戶(hu)特(te)別要謹記。
