（1）充電電池的容量

消費(fei)者要根(gen)據電(dian)(dian)器耗電(dian)(dian)量大(da)(da)小來購買(mai)電(dian)(dian)池(chi)。電(dian)(dian)容(rong)量越大(da)(da)的(de)電(dian)(dian)池(chi)，瞬間(jian)工作(zuo)電(dian)(dian)流大(da)(da)，因此對(dui)電(dian)(dian)器電(dian)(dian)路的(de)要求高，搞不好(hao)會燒(shao)壞電(dian)(dian)路。同(tong)時對(dui)電(dian)(dian)池(chi)自身的(de)損耗也(ye)大(da)(da)。電(dian)(dian)容(rong)量大(da)(da)的(de)電(dian)(dian)池(chi)，充(chong)電(dian)(dian)循環次數(shu)相對(dui)要少，也(ye)就(jiu)是壽(shou)命相對(dui)較短。

因此，耗電(dian)(dian)(dian)量中等以(yi)下的(de)(de)(de)電(dian)(dian)(dian)器(qi)，如mp3、無線鼠標、小型玩具(ju)、手電(dian)(dian)(dian)筒等，選用(yong)1300-1800毫(hao)安時的(de)(de)(de)5號(hao)(hao)電(dian)(dian)(dian)池或(huo)者600-800毫(hao)安時的(de)(de)(de)7號(hao)(hao)電(dian)(dian)(dian)池就可(ke)以(yi)，耗電(dian)(dian)(dian)量大的(de)(de)(de)電(dian)(dian)(dian)器(qi)，如相機、剃(ti)須刀、電(dian)(dian)(dian)動牙刷、話筒、玩具(ju)汽(qi)車、航模等，需要選用(yong)2000-2600毫(hao)安時的(de)(de)(de)5號(hao)(hao)電(dian)(dian)(dian)池或(huo)850-1000毫(hao)安時的(de)(de)(de)7號(hao)(hao)電(dian)(dian)(dian)池。

（2）充電電池的自放電

充電(dian)(dian)電(dian)(dian)池(chi)(chi)放(fang)置一段時間(jian)后，電(dian)(dian)量會逐漸減少，稱之(zhi)為(wei)自放(fang)電(dian)(dian)。品質(zhi)不好(hao)的電(dian)(dian)池(chi)(chi)，自放(fang)電(dian)(dian)現(xian)象(xiang)嚴重。這(zhe)樣，為(wei)了滿足使用，充電(dian)(dian)電(dian)(dian)池(chi)(chi)需要頻繁(fan)充電(dian)(dian)，從而降低了電(dian)(dian)池(chi)(chi)使用壽命。

低自(zi)放(fang)電(dian)充電(dian)電(dian)池(chi)也就應(ying)運而(er)生。品(pin)質優(you)異的(de)低自(zi)放(fang)電(dian)電(dian)池(chi)，據說放(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(xiao)費者的(de)日常使(shi)用，也(ye)提高(gao)了電(dian)池(chi)的(de)使(shi)用周期。當然(ran)，低自(zi)放電(dian)池(chi)的(de)價格會高(gao)于普通(tong)充電(dian)電(dian)池(chi)。

如果使用(yong)(yong)充電(dian)(dian)電(dian)(dian)池(chi)(chi)不是很(hen)頻繁，使用(yong)(yong)一(yi)次電(dian)(dian)池(chi)(chi)后會放置一(yi)段時間，建(jian)議考(kao)慮購買低自放電(dian)(dian)電(dian)(dian)池(chi)(chi)。若使用(yong)(yong)充電(dian)(dian)電(dian)(dian)池(chi)(chi)的頻率很(hen)高，購買普通充電(dian)(dian)電(dian)(dian)池(chi)(chi)就(jiu)可以了。

（3）電池類型的選擇

如果需要(yao)為耗電(dian)(dian)(dian)(dian)量大的電(dian)(dian)(dian)(dian)器如相機(ji)、玩具汽(qi)車(che)、剃須(xu)刀(dao)等(deng)購(gou)買(mai)(mai)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，建(jian)議考慮充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)和堿性(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，這時最好不(bu)要(yao)貪便宜(yi)買(mai)(mai)碳性(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。對于耗電(dian)(dian)(dian)(dian)量低(di)的遙控器、鐘表、收音機(ji)等(deng)，便宜(yi)的碳性(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)足夠。家里有終止電(dian)(dian)(dian)(dian)壓(ya)較高的電(dian)(dian)(dian)(dian)器，推薦購(gou)買(mai)(mai)優質的堿性(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)或(huo)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。

（1）充電電池到(dao)手(shou)后，需要(yao)反(fan)復(fu)充放3-4次(ci)，才能充(chong)(chong)(chong)分激(ji)活電(dian)池，達到最佳使用狀(zhuang)態。首次(ci)充(chong)(chong)(chong)電(dian)前，最好(hao)把余電(dian)用完，首次(ci)充(chong)(chong)(chong)電(dian)的時(shi)間(jian)可以比建議充(chong)(chong)(chong)電(dian)時(shi)間(jian)稍(shao)長。充(chong)(chong)(chong)電(dian)時(shi)最好(hao)一次(ci)性充(chong)(chong)(chong)滿(man)，不(bu)要充(chong)(chong)(chong)一下(xia)(xia)用一下(xia)(xia)又接著充(chong)(chong)(chong)。

（2）電池(chi)(chi)使用和充(chong)電時一(yi)定(ding)把正(zheng)負極對好，否則可(ke)能燒壞(huai)電池(chi)(chi)或者電器。不要嘗(chang)試(shi)給一(yi)次性電池(chi)(chi)充(chong)電。

（3）需要同時(shi)使(shi)用多節電池時(shi)，最好選擇容量和(he)狀態一(yi)致(zhi)的電池，道理和(he)短板效應一(yi)致(zhi)。例如，最好不(bu)同時(shi)使(shi)用1300毫(hao)安時和(he)1800毫(hao)安時的電(dian)(dian)池(chi)(chi)，不同時使用(yong)新電(dian)(dian)池(chi)(chi)和(he)老電(dian)(dian)池(chi)(chi)，否則將會降低大容量電(dian)(dian)池(chi)(chi)或者新電(dian)(dian)池(chi)(chi)的效用(yong)。

（4）充(chong)電(dian)(dian)(dian)(dian)時(shi)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)和(he)電(dian)(dian)(dian)(dian)池發熱是正常的(de)，所以充(chong)電(dian)(dian)(dian)(dian)時(shi)請注意周圍不要有易燃(ran)易爆物品。如果(guo)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)和(he)電(dian)(dian)(dian)(dian)池時(shi)過于發燙，可以先拔掉電(dian)(dian)(dian)(dian)源停止充(chong)電(dian)(dian)(dian)(dian)，等(deng)待溫(wen)度下降后，再充(chong)電(dian)(dian)(dian)(dian)。

（5）如果一段時間不使用電(dian)(dian)池(chi)(chi)，建議(yi)把電(dian)(dian)池(chi)(chi)拿出來，將(jiang)電(dian)(dian)池(chi)(chi)和(he)充(chong)電(dian)(dian)器放置(zhi)在干燥地方(fang)存放，用電(dian)(dian)池(chi)(chi)盒存放電(dian)(dian)池(chi)(chi)最好。電(dian)(dian)池(chi)(chi)放置(zhi)時注意不要短路，有個客戶(hu)曾經把電(dian)(dian)池(chi)(chi)和(he)一大串鑰(yao)匙放在一起(qi)，結果導致短路，電(dian)(dian)池(chi)(chi)損(sun)壞。

（6）從充(chong)電器(qi)里取(qu)放(fang)電池時(shi)，注(zhu)意輕(qing)拿輕(qing)放(fang)。如果(guo)從充(chong)電器(qi)里野蠻地(di)摳放(fang)電池，會很(hen)快損壞電池膠(jiao)腸，影(ying)響電池壽命。這點KTV客(ke)戶特別要(yao)謹記(ji)。
