（1）充電電池的容量

消費者要(yao)根(gen)據(ju)電器(qi)耗電量(liang)(liang)大(da)(da)(da)小來購買電池。電容量(liang)(liang)越大(da)(da)(da)的(de)(de)電池，瞬間工(gong)作電流大(da)(da)(da)，因此對電器(qi)電路的(de)(de)要(yao)求高，搞不好會(hui)燒壞電路。同時對電池自身的(de)(de)損耗也大(da)(da)(da)。電容量(liang)(liang)大(da)(da)(da)的(de)(de)電池，充電循環次數(shu)相(xiang)對要(yao)少，也就是壽命相(xiang)對較短。

因(yin)此，耗電(dian)量中等以(yi)下的(de)(de)電(dian)器(qi)，如(ru)mp3、無線鼠標、小型(xing)玩(wan)具、手電(dian)筒(tong)等，選用1300-1800毫(hao)安時的(de)(de)5號(hao)(hao)(hao)電(dian)池(chi)或者600-800毫(hao)安時的(de)(de)7號(hao)(hao)(hao)電(dian)池(chi)就可以(yi)，耗電(dian)量大的(de)(de)電(dian)器(qi)，如(ru)相機、剃須(xu)刀、電(dian)動牙刷、話筒(tong)、玩(wan)具汽(qi)車、航模等，需要選用2000-2600毫(hao)安時的(de)(de)5號(hao)(hao)(hao)電(dian)池(chi)或850-1000毫(hao)安時的(de)(de)7號(hao)(hao)(hao)電(dian)池(chi)。

（2）充電電池的自放電

充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)放置一段時間后，電(dian)(dian)(dian)(dian)量會逐漸減少，稱之為自(zi)放電(dian)(dian)(dian)(dian)。品質不好的電(dian)(dian)(dian)(dian)池(chi)，自(zi)放電(dian)(dian)(dian)(dian)現(xian)象嚴重。這樣(yang)，為了滿足使用，充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)需(xu)要(yao)頻繁充電(dian)(dian)(dian)(dian)，從而降低了電(dian)(dian)(dian)(dian)池(chi)使用壽命。

低自放電充電電池也就應運而生。品質(zhi)優(you)異(yi)的低自放電電池，據說(shuo)放置2年后(hou)，還能(neng)保持(chi)80%以上的電(dian)(dian)量，大大方便了消費者的日常(chang)使用，也提高了電(dian)(dian)池(chi)的使用周期(qi)。當然(ran)，低自放電(dian)(dian)池(chi)的價(jia)格(ge)會高于普通充電(dian)(dian)電(dian)(dian)池(chi)。

如果使用(yong)充(chong)電(dian)(dian)電(dian)(dian)池(chi)不是很頻繁，使用(yong)一次電(dian)(dian)池(chi)后會放置一段時間，建議考慮購(gou)(gou)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(lv)很高(gao)，購(gou)(gou)買(mai)普通充(chong)電(dian)(dian)電(dian)(dian)池(chi)就可以了(le)。

（3）電池類型的選擇

如果(guo)需要為耗電(dian)(dian)量(liang)(liang)大的(de)(de)(de)電(dian)(dian)器(qi)(qi)如相機、玩具(ju)汽車(che)、剃須刀等購(gou)買電(dian)(dian)池(chi)(chi)，建(jian)議考慮充(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)和(he)堿(jian)性(xing)電(dian)(dian)池(chi)(chi)，這時(shi)最好不要貪(tan)便宜(yi)(yi)買碳(tan)性(xing)電(dian)(dian)池(chi)(chi)。對于(yu)耗電(dian)(dian)量(liang)(liang)低的(de)(de)(de)遙控器(qi)(qi)、鐘表、收音機等，便宜(yi)(yi)的(de)(de)(de)碳(tan)性(xing)電(dian)(dian)池(chi)(chi)足夠。家里(li)有終止電(dian)(dian)壓(ya)較高的(de)(de)(de)電(dian)(dian)器(qi)(qi)，推薦購(gou)買優(you)質的(de)(de)(de)堿(jian)性(xing)電(dian)(dian)池(chi)(chi)或充(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)。

（1）充電電池到手后，需要反復充放(fang)3-4次，才能充(chong)(chong)分激活電(dian)(dian)池，達到最(zui)佳使用狀(zhuang)態。首次充(chong)(chong)電(dian)(dian)前，最(zui)好(hao)把余電(dian)(dian)用完，首次充(chong)(chong)電(dian)(dian)的時間(jian)(jian)可以(yi)比(bi)建議(yi)充(chong)(chong)電(dian)(dian)時間(jian)(jian)稍(shao)長。充(chong)(chong)電(dian)(dian)時最(zui)好(hao)一(yi)次性充(chong)(chong)滿，不要(yao)充(chong)(chong)一(yi)下用一(yi)下又接著(zhu)充(chong)(chong)。

（2）電(dian)池使用和(he)充(chong)電(dian)時一定把正負極對(dui)好，否則可能燒(shao)壞電(dian)池或者電(dian)器。不(bu)要嘗試(shi)給一次性電(dian)池充(chong)電(dian)。

（3）需(xu)要同(tong)時(shi)(shi)使用(yong)多節電池時(shi)(shi)，最(zui)好選擇容(rong)量(liang)和(he)狀態一致(zhi)的電池，道理和(he)短板(ban)效(xiao)應一致(zhi)。例如，最(zui)好不同(tong)時(shi)(shi)使用(yong)1300毫安時(shi)和1800毫安時(shi)的電(dian)池(chi)，不(bu)同時(shi)使用(yong)新(xin)(xin)電(dian)池(chi)和老電(dian)池(chi)，否(fou)則將會降(jiang)低大容量(liang)電(dian)池(chi)或者新(xin)(xin)電(dian)池(chi)的效(xiao)用(yong)。

（4）充電(dian)時(shi)充電(dian)器(qi)和電(dian)池發熱是正(zheng)常的，所以充電(dian)時(shi)請注意(yi)周圍不要有易(yi)燃易(yi)爆物品。如果充電(dian)器(qi)和電(dian)池時(shi)過于發燙，可(ke)以先拔掉電(dian)源停(ting)止充電(dian)，等待溫度下降后(hou)，再充電(dian)。

（5）如果(guo)一段時(shi)間不(bu)使用電(dian)(dian)池，建(jian)議把(ba)電(dian)(dian)池拿(na)出來，將電(dian)(dian)池和充電(dian)(dian)器放置(zhi)(zhi)在干燥地方(fang)存放，用電(dian)(dian)池盒存放電(dian)(dian)池最(zui)好。電(dian)(dian)池放置(zhi)(zhi)時(shi)注意不(bu)要短路(lu)，有個(ge)客戶曾(ceng)經把(ba)電(dian)(dian)池和一大串鑰匙(chi)放在一起(qi)，結果(guo)導致短路(lu)，電(dian)(dian)池損壞(huai)。

（6）從充(chong)電(dian)器(qi)(qi)里(li)取(qu)放電(dian)池時，注意輕(qing)拿輕(qing)放。如(ru)果(guo)從充(chong)電(dian)器(qi)(qi)里(li)野蠻地摳放電(dian)池，會很快損壞電(dian)池膠腸，影響電(dian)池壽命。這點KTV客戶特別要謹記。
