（1）充電電池的容量

消費者(zhe)要(yao)(yao)(yao)根據電(dian)(dian)(dian)(dian)(dian)器(qi)耗(hao)(hao)電(dian)(dian)(dian)(dian)(dian)量大(da)小來購買電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。電(dian)(dian)(dian)(dian)(dian)容(rong)量越大(da)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，瞬間工作(zuo)電(dian)(dian)(dian)(dian)(dian)流(liu)大(da)，因此對電(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)要(yao)(yao)(yao)求高，搞(gao)不(bu)好會燒(shao)壞電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)。同(tong)時(shi)對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)自身的(de)損耗(hao)(hao)也(ye)大(da)。電(dian)(dian)(dian)(dian)(dian)容(rong)量大(da)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，充電(dian)(dian)(dian)(dian)(dian)循環次(ci)數相對要(yao)(yao)(yao)少，也(ye)就是壽命相對較(jiao)短。

因此，耗電(dian)量中(zhong)等以下(xia)的電(dian)器，如mp3、無線鼠標(biao)、小型玩具、手電(dian)筒等，選(xuan)用1300-1800毫安(an)時(shi)的5號(hao)電(dian)池(chi)(chi)或者600-800毫安(an)時(shi)的7號(hao)電(dian)池(chi)(chi)就可以，耗電(dian)量大的電(dian)器，如相機、剃須刀、電(dian)動牙刷、話筒、玩具汽車(che)、航模等，需要選(xuan)用2000-2600毫安(an)時(shi)的5號(hao)電(dian)池(chi)(chi)或850-1000毫安(an)時(shi)的7號(hao)電(dian)池(chi)(chi)。

（2）充電電池的自放電

充(chong)電(dian)電(dian)池(chi)(chi)放置一段時間后，電(dian)量會逐漸減少，稱之為自放電(dian)。品質不好的電(dian)池(chi)(chi)，自放電(dian)現(xian)象嚴重。這樣，為了滿足使(shi)(shi)用，充(chong)電(dian)電(dian)池(chi)(chi)需要頻繁(fan)充(chong)電(dian)，從而降低(di)了電(dian)池(chi)(chi)使(shi)(shi)用壽(shou)命。

低自放(fang)(fang)電(dian)(dian)(dian)充電(dian)(dian)(dian)電(dian)(dian)(dian)池也就應運而生。品質優異的(de)低自放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)池，據說放(fang)(fang)置(zhi)2年后，還能保持80%以上的(de)電量，大大方便了(le)(le)消費者的(de)日常使用，也提高了(le)(le)電池(chi)(chi)的(de)使用周期。當(dang)然，低自放電池(chi)(chi)的(de)價格會高于普通(tong)充電電池(chi)(chi)。

如果(guo)使用(yong)(yong)充電(dian)(dian)(dian)電(dian)(dian)(dian)池不是很頻繁，使用(yong)(yong)一(yi)次(ci)電(dian)(dian)(dian)池后會(hui)放置(zhi)一(yi)段時間，建(jian)議考慮購買(mai)低自(zi)放電(dian)(dian)(dian)電(dian)(dian)(dian)池。若使用(yong)(yong)充電(dian)(dian)(dian)電(dian)(dian)(dian)池的(de)頻率很高，購買(mai)普通充電(dian)(dian)(dian)電(dian)(dian)(dian)池就可以了。

（3）電池類型的選擇

如(ru)果需要為耗電(dian)量(liang)大的電(dian)器(qi)如(ru)相機、玩具(ju)汽車、剃須刀等購買電(dian)池(chi)(chi)，建議考(kao)慮充(chong)電(dian)電(dian)池(chi)(chi)和堿性(xing)電(dian)池(chi)(chi)，這時最好不(bu)要貪便宜買碳性(xing)電(dian)池(chi)(chi)。對于耗電(dian)量(liang)低的遙控器(qi)、鐘表(biao)、收(shou)音機等，便宜的碳性(xing)電(dian)池(chi)(chi)足夠。家里有(you)終止(zhi)電(dian)壓較(jiao)高的電(dian)器(qi)，推薦購買優(you)質的堿性(xing)電(dian)池(chi)(chi)或充(chong)電(dian)電(dian)池(chi)(chi)。

（1）充(chong)(chong)電電池到手后，需要(yao)反復充(chong)(chong)放(fang)3-4次，才能充(chong)(chong)(chong)分激活電(dian)池，達到最佳使用(yong)狀態。首(shou)次充(chong)(chong)(chong)電(dian)前，最好(hao)把(ba)余(yu)電(dian)用(yong)完(wan)，首(shou)次充(chong)(chong)(chong)電(dian)的時(shi)間(jian)(jian)可(ke)以比建議充(chong)(chong)(chong)電(dian)時(shi)間(jian)(jian)稍長。充(chong)(chong)(chong)電(dian)時(shi)最好(hao)一次性充(chong)(chong)(chong)滿，不要充(chong)(chong)(chong)一下用(yong)一下又接著充(chong)(chong)(chong)。

（2）電(dian)池(chi)使用和(he)充電(dian)時一定把正負(fu)極對(dui)好，否則可能燒壞電(dian)池(chi)或者(zhe)電(dian)器。不(bu)要嘗(chang)試(shi)給一次性電(dian)池(chi)充電(dian)。

（3）需要同(tong)(tong)時(shi)(shi)使(shi)用多節(jie)電(dian)池時(shi)(shi)，最好選(xuan)擇容量(liang)和狀(zhuang)態(tai)一(yi)致的電(dian)池，道理和短板效應一(yi)致。例如，最好不同(tong)(tong)時(shi)(shi)使(shi)用1300毫安時和1800毫安(an)時的電池(chi)，不同時使用新(xin)電池(chi)和老電池(chi)，否則將會降低大容量電池(chi)或(huo)者新(xin)電池(chi)的效用。

（4）充(chong)電(dian)(dian)時充(chong)電(dian)(dian)器和(he)電(dian)(dian)池(chi)發(fa)熱是正(zheng)常的，所以充(chong)電(dian)(dian)時請注意周圍(wei)不要有易燃易爆物品(pin)。如果(guo)充(chong)電(dian)(dian)器和(he)電(dian)(dian)池(chi)時過于發(fa)燙，可以先拔掉電(dian)(dian)源停(ting)止(zhi)充(chong)電(dian)(dian)，等待溫(wen)度下降(jiang)后，再充(chong)電(dian)(dian)。

（5）如果一(yi)(yi)段時間不使用電池(chi)，建議把電池(chi)拿出(chu)來，將電池(chi)和(he)充(chong)電器放置(zhi)在干燥(zao)地(di)方存(cun)放，用電池(chi)盒存(cun)放電池(chi)最好。電池(chi)放置(zhi)時注意不要短路，有個客戶(hu)曾經把電池(chi)和(he)一(yi)(yi)大串鑰匙放在一(yi)(yi)起，結果導致短路，電池(chi)損壞。

（6）從充電(dian)(dian)器(qi)里(li)取放電(dian)(dian)池時，注意輕(qing)拿(na)輕(qing)放。如果從充電(dian)(dian)器(qi)里(li)野蠻地摳放電(dian)(dian)池，會(hui)很(hen)快損壞電(dian)(dian)池膠腸，影(ying)響電(dian)(dian)池壽命(ming)。這點KTV客戶特別要謹記。
