（1）充電電池的容量

消(xiao)費者(zhe)要(yao)根據(ju)電(dian)器(qi)耗(hao)電(dian)量(liang)大小(xiao)來購買電(dian)池。電(dian)容量(liang)越大的電(dian)池，瞬(shun)間(jian)工作(zuo)電(dian)流(liu)大，因此對(dui)電(dian)器(qi)電(dian)路(lu)(lu)的要(yao)求高(gao)，搞不好會燒壞(huai)電(dian)路(lu)(lu)。同時對(dui)電(dian)池自身的損耗(hao)也大。電(dian)容量(liang)大的電(dian)池，充電(dian)循環次數相對(dui)要(yao)少，也就是壽(shou)命相對(dui)較短。

因此(ci)，耗電(dian)量中等以下的(de)電(dian)器，如mp3、無(wu)線鼠標、小(xiao)型玩具(ju)、手(shou)電(dian)筒(tong)等，選(xuan)用(yong)1300-1800毫安(an)(an)時的(de)5號(hao)電(dian)池(chi)或者600-800毫安(an)(an)時的(de)7號(hao)電(dian)池(chi)就可以，耗電(dian)量大的(de)電(dian)器，如相機、剃須刀(dao)、電(dian)動(dong)牙(ya)刷(shua)、話(hua)筒(tong)、玩具(ju)汽車、航模等，需要選(xuan)用(yong)2000-2600毫安(an)(an)時的(de)5號(hao)電(dian)池(chi)或850-1000毫安(an)(an)時的(de)7號(hao)電(dian)池(chi)。

（2）充電電池的自放電

充電(dian)(dian)電(dian)(dian)池(chi)(chi)放置一段(duan)時間后，電(dian)(dian)量會(hui)逐漸(jian)減少，稱之為自放電(dian)(dian)。品質(zhi)不好(hao)的(de)電(dian)(dian)池(chi)(chi)，自放電(dian)(dian)現象嚴重。這樣(yang)，為了滿足使(shi)用，充電(dian)(dian)電(dian)(dian)池(chi)(chi)需要頻繁充電(dian)(dian)，從而降低了電(dian)(dian)池(chi)(chi)使(shi)用壽命(ming)。

低自(zi)放(fang)電充電電池也就應運而生。品質優異(yi)的(de)低自(zi)放(fang)電電池，據(ju)說放(fang)置2年(nian)后，還(huan)能保持80%以上的(de)電(dian)量，大大方便了消費者的(de)日常(chang)使用，也提(ti)高了電(dian)池(chi)的(de)使用周期。當(dang)然，低自放電(dian)池(chi)的(de)價格會高于普通(tong)充(chong)電(dian)電(dian)池(chi)。

如果使用(yong)充(chong)電(dian)(dian)電(dian)(dian)池(chi)不是很(hen)頻繁(fan)，使用(yong)一次電(dian)(dian)池(chi)后會放置(zhi)一段時間，建(jian)議考慮(lv)購買(mai)低自放電(dian)(dian)電(dian)(dian)池(chi)。若使用(yong)充(chong)電(dian)(dian)電(dian)(dian)池(chi)的頻率很(hen)高，購買(mai)普(pu)通充(chong)電(dian)(dian)電(dian)(dian)池(chi)就可以了。

（3）電池類型的選擇

如果需要為耗(hao)電(dian)(dian)量大的(de)(de)電(dian)(dian)器如相機、玩(wan)具(ju)汽車、剃須刀(dao)等購買電(dian)(dian)池(chi)(chi)，建議(yi)考慮充電(dian)(dian)電(dian)(dian)池(chi)(chi)和堿性(xing)電(dian)(dian)池(chi)(chi)，這(zhe)時最好不(bu)要貪便宜買碳性(xing)電(dian)(dian)池(chi)(chi)。對于(yu)耗(hao)電(dian)(dian)量低(di)的(de)(de)遙控器、鐘(zhong)表、收音機等，便宜的(de)(de)碳性(xing)電(dian)(dian)池(chi)(chi)足(zu)夠。家里有終(zhong)止電(dian)(dian)壓較高的(de)(de)電(dian)(dian)器，推薦購買優(you)質的(de)(de)堿性(xing)電(dian)(dian)池(chi)(chi)或充電(dian)(dian)電(dian)(dian)池(chi)(chi)。

（1）充(chong)電電池(chi)到手后，需要反復充(chong)放3-4次(ci)(ci)，才能充(chong)分激活電池，達到最佳使用(yong)狀(zhuang)態。首次(ci)(ci)充(chong)電前，最好(hao)把余電用(yong)完，首次(ci)(ci)充(chong)電的時間(jian)可以比(bi)建議充(chong)電時間(jian)稍長(chang)。充(chong)電時最好(hao)一次(ci)(ci)性充(chong)滿，不(bu)要充(chong)一下用(yong)一下又接著充(chong)。

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

（3）需要(yao)同時使用多(duo)節(jie)電池時，最好(hao)選擇(ze)容量(liang)和(he)狀(zhuang)態一致(zhi)的電池，道理和(he)短板效應(ying)一致(zhi)。例如，最好(hao)不同時使用1300毫(hao)安時和1800毫安(an)時的電(dian)池(chi)(chi)(chi)，不同時使用新(xin)電(dian)池(chi)(chi)(chi)和老電(dian)池(chi)(chi)(chi)，否則(ze)將(jiang)會降低(di)大容量電(dian)池(chi)(chi)(chi)或者新(xin)電(dian)池(chi)(chi)(chi)的效用。

（4）充電(dian)時(shi)充電(dian)器和電(dian)池(chi)發熱是正常的，所以充電(dian)時(shi)請注(zhu)意周圍不要有易(yi)燃(ran)易(yi)爆物(wu)品。如果充電(dian)器和電(dian)池(chi)時(shi)過于發燙，可(ke)以先拔掉電(dian)源停止充電(dian)，等待溫度下降后，再充電(dian)。

（5）如果一(yi)段時(shi)間不使用(yong)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，建議把電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)拿出來(lai)，將電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和(he)充電(dian)(dian)(dian)(dian)(dian)器(qi)放置(zhi)在干燥(zao)地(di)方存放，用(yong)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)盒存放電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)最好。電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)放置(zhi)時(shi)注(zhu)意(yi)不要短路(lu)，有個客戶(hu)曾經把電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和(he)一(yi)大串鑰匙放在一(yi)起(qi)，結果導(dao)致短路(lu)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)損壞。

（6）從(cong)(cong)充電(dian)器里取放(fang)(fang)電(dian)池(chi)(chi)時(shi)，注意輕拿(na)輕放(fang)(fang)。如果從(cong)(cong)充電(dian)器里野蠻地摳放(fang)(fang)電(dian)池(chi)(chi)，會很(hen)快損壞電(dian)池(chi)(chi)膠腸，影響電(dian)池(chi)(chi)壽命。這(zhe)點KTV客(ke)戶(hu)特別要謹(jin)記。
