（1）充電電池的容量

消費者要根據電(dian)(dian)(dian)器(qi)耗電(dian)(dian)(dian)量(liang)(liang)大(da)小來購買電(dian)(dian)(dian)池(chi)。電(dian)(dian)(dian)容(rong)量(liang)(liang)越(yue)大(da)的(de)電(dian)(dian)(dian)池(chi)，瞬間(jian)工作電(dian)(dian)(dian)流(liu)大(da)，因此對電(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)路的(de)要求高(gao)，搞不(bu)好會燒壞電(dian)(dian)(dian)路。同時對電(dian)(dian)(dian)池(chi)自身的(de)損耗也大(da)。電(dian)(dian)(dian)容(rong)量(liang)(liang)大(da)的(de)電(dian)(dian)(dian)池(chi)，充(chong)電(dian)(dian)(dian)循環次數相對要少，也就是壽(shou)命相對較短(duan)。

因此，耗電(dian)量(liang)中等(deng)以下的(de)(de)電(dian)器，如(ru)mp3、無線鼠標、小型玩具、手電(dian)筒(tong)等(deng)，選(xuan)用1300-1800毫(hao)安時(shi)的(de)(de)5號電(dian)池或者600-800毫(hao)安時(shi)的(de)(de)7號電(dian)池就可以，耗電(dian)量(liang)大的(de)(de)電(dian)器，如(ru)相(xiang)機、剃須刀、電(dian)動牙刷、話筒(tong)、玩具汽車、航模等(deng)，需要(yao)選(xuan)用2000-2600毫(hao)安時(shi)的(de)(de)5號電(dian)池或850-1000毫(hao)安時(shi)的(de)(de)7號電(dian)池。

（2）充電電池的自放電

充(chong)電電池(chi)(chi)放置一段時間(jian)后，電量會逐漸減少，稱之為自放電。品(pin)質不(bu)好(hao)的電池(chi)(chi)，自放電現象嚴重。這樣，為了(le)(le)滿足使(shi)用，充(chong)電電池(chi)(chi)需要頻繁充(chong)電，從而降低了(le)(le)電池(chi)(chi)使(shi)用壽命。

低自放電(dian)充電(dian)電(dian)池也就(jiu)應運而生。品質優異(yi)的低自放電(dian)電(dian)池，據(ju)說(shuo)放置(zhi)2年后(hou)，還能保持(chi)80%以上的(de)電(dian)(dian)量(liang)，大(da)大(da)方便了消費者的(de)日常使(shi)用，也提高了電(dian)(dian)池的(de)使(shi)用周期(qi)。當然，低自放電(dian)(dian)池的(de)價格會高于(yu)普通充電(dian)(dian)電(dian)(dian)池。

如果使(shi)用充(chong)電(dian)電(dian)池不是很頻繁，使(shi)用一(yi)次電(dian)池后(hou)會放(fang)置一(yi)段時間，建議考慮購(gou)買(mai)低自放(fang)電(dian)電(dian)池。若使(shi)用充(chong)電(dian)電(dian)池的頻率很高，購(gou)買(mai)普通充(chong)電(dian)電(dian)池就可(ke)以了。

（3）電池類型的選擇

如果需(xu)要為耗電(dian)量(liang)大的(de)電(dian)器(qi)如相機、玩具汽車、剃須刀等購買電(dian)池(chi)，建議考慮充電(dian)電(dian)池(chi)和堿性電(dian)池(chi)，這時最好不要貪(tan)便宜(yi)買碳(tan)性電(dian)池(chi)。對于耗電(dian)量(liang)低的(de)遙控器(qi)、鐘表、收音機等，便宜(yi)的(de)碳(tan)性電(dian)池(chi)足夠(gou)。家里有(you)終止電(dian)壓較高的(de)電(dian)器(qi)，推薦購買優(you)質的(de)堿性電(dian)池(chi)或充電(dian)電(dian)池(chi)。

（1）充電(dian)電(dian)池到手后，需要反(fan)復充放(fang)3-4次(ci)，才(cai)能充(chong)(chong)分(fen)激活(huo)電(dian)池，達到最佳使(shi)用(yong)狀態。首次(ci)充(chong)(chong)電(dian)前，最好(hao)把(ba)余電(dian)用(yong)完，首次(ci)充(chong)(chong)電(dian)的(de)時間(jian)可(ke)以比建議充(chong)(chong)電(dian)時間(jian)稍(shao)長。充(chong)(chong)電(dian)時最好(hao)一(yi)次(ci)性充(chong)(chong)滿，不要(yao)充(chong)(chong)一(yi)下用(yong)一(yi)下又接著充(chong)(chong)。

（2）電(dian)池使用和充電(dian)時(shi)一(yi)定(ding)把(ba)正負極(ji)對好(hao)，否則(ze)可能燒壞電(dian)池或者(zhe)電(dian)器。不要嘗試給一(yi)次性電(dian)池充電(dian)。

（3）需要同(tong)(tong)時(shi)使(shi)用多節電池(chi)時(shi)，最好選擇容量和狀態(tai)一(yi)致的電池(chi)，道理和短板效應一(yi)致。例如，最好不同(tong)(tong)時(shi)使(shi)用1300毫安時(shi)和(he)1800毫安時的(de)電池，不同時使(shi)用新電池和老(lao)電池，否(fou)則(ze)將會(hui)降低大容量電池或者新電池的(de)效用。

（4）充(chong)(chong)電(dian)時(shi)充(chong)(chong)電(dian)器和電(dian)池發熱是正常的，所以(yi)充(chong)(chong)電(dian)時(shi)請注(zhu)意周圍(wei)不要(yao)有易(yi)燃(ran)易(yi)爆物(wu)品。如果充(chong)(chong)電(dian)器和電(dian)池時(shi)過于發燙(tang)，可以(yi)先拔掉電(dian)源(yuan)停止(zhi)充(chong)(chong)電(dian)，等待溫(wen)度(du)下降后，再充(chong)(chong)電(dian)。

（5）如果(guo)一段時間不使用電(dian)(dian)池(chi)(chi)(chi)，建議把(ba)電(dian)(dian)池(chi)(chi)(chi)拿出來，將電(dian)(dian)池(chi)(chi)(chi)和充電(dian)(dian)器(qi)放置(zhi)在干燥(zao)地方存放，用電(dian)(dian)池(chi)(chi)(chi)盒存放電(dian)(dian)池(chi)(chi)(chi)最好(hao)。電(dian)(dian)池(chi)(chi)(chi)放置(zhi)時注意(yi)不要短(duan)路(lu)(lu)，有個客戶曾經把(ba)電(dian)(dian)池(chi)(chi)(chi)和一大串鑰匙放在一起，結果(guo)導致短(duan)路(lu)(lu)，電(dian)(dian)池(chi)(chi)(chi)損壞。

（6）從充電器里取放電池時，注意輕拿輕放。如果從充電器里野蠻地摳放電池，會很(hen)快(kuai)損壞電池膠腸，影(ying)響電池壽命。這點KTV客(ke)戶特別要謹記(ji)。
