（1）充電電池的容量

消費者(zhe)要(yao)根(gen)據電(dian)器耗(hao)電(dian)量(liang)大小(xiao)來購(gou)買電(dian)池(chi)。電(dian)容量(liang)越大的(de)(de)電(dian)池(chi)，瞬間工作電(dian)流大，因此對電(dian)器電(dian)路(lu)(lu)的(de)(de)要(yao)求高，搞(gao)不好會燒壞(huai)電(dian)路(lu)(lu)。同時對電(dian)池(chi)自(zi)身的(de)(de)損耗(hao)也(ye)大。電(dian)容量(liang)大的(de)(de)電(dian)池(chi)，充電(dian)循環次數(shu)相對要(yao)少，也(ye)就是壽命相對較短。

因此，耗電(dian)(dian)(dian)量(liang)中等(deng)(deng)(deng)以(yi)下的電(dian)(dian)(dian)器(qi)，如mp3、無(wu)線鼠標、小型玩(wan)具、手電(dian)(dian)(dian)筒(tong)等(deng)(deng)(deng)，選用1300-1800毫安時的5號(hao)電(dian)(dian)(dian)池(chi)或(huo)者600-800毫安時的7號(hao)電(dian)(dian)(dian)池(chi)就(jiu)可以(yi)，耗電(dian)(dian)(dian)量(liang)大的電(dian)(dian)(dian)器(qi)，如相機、剃須刀、電(dian)(dian)(dian)動牙刷、話筒(tong)、玩(wan)具汽車、航模等(deng)(deng)(deng)，需要選用2000-2600毫安時的5號(hao)電(dian)(dian)(dian)池(chi)或(huo)850-1000毫安時的7號(hao)電(dian)(dian)(dian)池(chi)。

（2）充電電池的自放電

充電電池放置一段時間后，電量會逐漸(jian)減少，稱之為(wei)自放電。品質不(bu)好(hao)的(de)電池，自放電現象嚴(yan)重(zhong)。這樣，為(wei)了(le)滿足使用(yong)，充電電池需要頻繁(fan)充電，從(cong)而(er)降低了(le)電池使用(yong)壽命。

低自(zi)(zi)放(fang)(fang)電(dian)充電(dian)電(dian)池(chi)也就應運(yun)而(er)生。品質優異的低自(zi)(zi)放(fang)(fang)電(dian)電(dian)池(chi)，據說放(fang)(fang)置2年后，還能保持80%以上的(de)電(dian)量，大大方便了消費者的(de)日常使用，也(ye)提(ti)高了電(dian)池的(de)使用周期。當然(ran)，低自放電(dian)池的(de)價(jia)格會(hui)高于普通充(chong)電(dian)電(dian)池。

如果(guo)使用(yong)充(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)不(bu)是很頻(pin)繁，使用(yong)一次電(dian)(dian)池(chi)后會放置(zhi)一段時間，建議考慮購(gou)買低自(zi)放電(dian)(dian)電(dian)(dian)池(chi)。若使用(yong)充(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)的頻(pin)率很高(gao)，購(gou)買普通充(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)就可以了(le)。

（3）電池類型的選擇

如果需要(yao)為耗電(dian)(dian)量(liang)大的(de)(de)(de)電(dian)(dian)器(qi)(qi)如相(xiang)機、玩(wan)具(ju)汽車、剃(ti)須刀等(deng)購買(mai)電(dian)(dian)池(chi)，建議考慮充(chong)電(dian)(dian)電(dian)(dian)池(chi)和堿(jian)性(xing)電(dian)(dian)池(chi)，這時最好不(bu)要(yao)貪便宜(yi)買(mai)碳性(xing)電(dian)(dian)池(chi)。對于耗電(dian)(dian)量(liang)低的(de)(de)(de)遙控器(qi)(qi)、鐘表(biao)、收音機等(deng)，便宜(yi)的(de)(de)(de)碳性(xing)電(dian)(dian)池(chi)足夠。家里(li)有終止電(dian)(dian)壓較高的(de)(de)(de)電(dian)(dian)器(qi)(qi)，推薦(jian)購買(mai)優質的(de)(de)(de)堿(jian)性(xing)電(dian)(dian)池(chi)或(huo)充(chong)電(dian)(dian)電(dian)(dian)池(chi)。

（1）充電(dian)電(dian)池到手(shou)后，需(xu)要反復充放(fang)3-4次(ci)，才(cai)能充(chong)(chong)(chong)分激活電(dian)池(chi)，達(da)到最佳使用(yong)狀態。首(shou)次(ci)充(chong)(chong)(chong)電(dian)前，最好(hao)(hao)把余電(dian)用(yong)完，首(shou)次(ci)充(chong)(chong)(chong)電(dian)的時間(jian)可以比(bi)建議充(chong)(chong)(chong)電(dian)時間(jian)稍長。充(chong)(chong)(chong)電(dian)時最好(hao)(hao)一次(ci)性充(chong)(chong)(chong)滿，不(bu)要充(chong)(chong)(chong)一下用(yong)一下又(you)接著(zhu)充(chong)(chong)(chong)。

（2）電(dian)池(chi)(chi)使用和(he)充電(dian)時一定(ding)把正負(fu)極對好，否則可能燒壞電(dian)池(chi)(chi)或者電(dian)器。不要(yao)嘗(chang)試給一次性電(dian)池(chi)(chi)充電(dian)。

（3）需要同時(shi)使用(yong)多(duo)節電池(chi)時(shi)，最好選擇(ze)容量和狀態一致的電池(chi)，道理和短板效應一致。例如，最好不同時(shi)使用(yong)1300毫安時和(he)1800毫安時的電(dian)(dian)池(chi)(chi)，不(bu)同時使用(yong)新電(dian)(dian)池(chi)(chi)和老電(dian)(dian)池(chi)(chi)，否則(ze)將會降低大容量電(dian)(dian)池(chi)(chi)或者新電(dian)(dian)池(chi)(chi)的效用(yong)。

（4）充電(dian)時(shi)充電(dian)器(qi)和(he)電(dian)池(chi)發熱是正(zheng)常的，所(suo)以(yi)(yi)充電(dian)時(shi)請注(zhu)意周圍不要有(you)易燃易爆(bao)物(wu)品。如果(guo)充電(dian)器(qi)和(he)電(dian)池(chi)時(shi)過于發燙(tang)，可以(yi)(yi)先拔掉電(dian)源停止充電(dian)，等待溫度(du)下降后(hou)，再(zai)充電(dian)。

（5）如果一段時間(jian)不使(shi)用電(dian)池(chi)(chi)(chi)(chi)，建議(yi)把電(dian)池(chi)(chi)(chi)(chi)拿(na)出來，將電(dian)池(chi)(chi)(chi)(chi)和充電(dian)器放(fang)置在(zai)干燥地方存(cun)放(fang)，用電(dian)池(chi)(chi)(chi)(chi)盒(he)存(cun)放(fang)電(dian)池(chi)(chi)(chi)(chi)最好。電(dian)池(chi)(chi)(chi)(chi)放(fang)置時注意不要短路(lu)，有個客戶(hu)曾經(jing)把電(dian)池(chi)(chi)(chi)(chi)和一大(da)串鑰(yao)匙放(fang)在(zai)一起，結果導致短路(lu)，電(dian)池(chi)(chi)(chi)(chi)損(sun)壞。

（6）從(cong)充電(dian)(dian)(dian)器里取放(fang)(fang)電(dian)(dian)(dian)池(chi)(chi)時，注(zhu)意輕(qing)拿輕(qing)放(fang)(fang)。如果(guo)從(cong)充電(dian)(dian)(dian)器里野(ye)蠻(man)地摳(kou)放(fang)(fang)電(dian)(dian)(dian)池(chi)(chi)，會很(hen)快損(sun)壞電(dian)(dian)(dian)池(chi)(chi)膠腸，影響電(dian)(dian)(dian)池(chi)(chi)壽(shou)命。這點KTV客(ke)戶特別要(yao)謹(jin)記。
