（1）充電電池的容量

消(xiao)費(fei)者(zhe)要根(gen)據電(dian)(dian)器耗(hao)電(dian)(dian)量(liang)大(da)小來(lai)購(gou)買電(dian)(dian)池。電(dian)(dian)容(rong)量(liang)越大(da)的(de)電(dian)(dian)池，瞬間工(gong)作電(dian)(dian)流大(da)，因(yin)此對電(dian)(dian)器電(dian)(dian)路的(de)要求高，搞(gao)不好會燒壞電(dian)(dian)路。同時對電(dian)(dian)池自身的(de)損耗(hao)也(ye)大(da)。電(dian)(dian)容(rong)量(liang)大(da)的(de)電(dian)(dian)池，充電(dian)(dian)循環次數相對要少，也(ye)就(jiu)是壽命相對較短。

因此，耗(hao)電(dian)(dian)(dian)量中(zhong)等(deng)以下的電(dian)(dian)(dian)器，如mp3、無(wu)線鼠標、小型(xing)玩具、手電(dian)(dian)(dian)筒等(deng)，選用(yong)1300-1800毫(hao)安(an)時的5號(hao)(hao)電(dian)(dian)(dian)池或者600-800毫(hao)安(an)時的7號(hao)(hao)電(dian)(dian)(dian)池就可以，耗(hao)電(dian)(dian)(dian)量大的電(dian)(dian)(dian)器，如相機、剃須刀、電(dian)(dian)(dian)動牙刷、話筒、玩具汽車、航模等(deng)，需要(yao)選用(yong)2000-2600毫(hao)安(an)時的5號(hao)(hao)電(dian)(dian)(dian)池或850-1000毫(hao)安(an)時的7號(hao)(hao)電(dian)(dian)(dian)池。

（2）充電電池的自放電

充(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)放置一段時間(jian)后，電(dian)(dian)量(liang)會(hui)逐(zhu)漸減少，稱(cheng)之為自放電(dian)(dian)。品質(zhi)不好的電(dian)(dian)池(chi)(chi)，自放電(dian)(dian)現象嚴(yan)重。這樣，為了(le)滿足使用，充(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)需要頻繁充(chong)電(dian)(dian)，從而降低了(le)電(dian)(dian)池(chi)(chi)使用壽命(ming)。

低自放電充(chong)電電池也就應運而生。品質優(you)異的低自放電電池，據說放置2年后，還能(neng)保持80%以上的(de)(de)電(dian)量，大大方便了消費者的(de)(de)日常使用，也提高了電(dian)池(chi)(chi)的(de)(de)使用周期。當然(ran)，低自放電(dian)池(chi)(chi)的(de)(de)價格會高于普通充(chong)電(dian)電(dian)池(chi)(chi)。

如(ru)果使用充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)不是很頻繁，使用一次電(dian)(dian)(dian)(dian)池(chi)后會放置一段時間，建議考慮購買低自放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)。若使用充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)的(de)頻率很高(gao)，購買普(pu)通(tong)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)就可以了。

（3）電池類型的選擇

如果需(xu)要為耗(hao)電(dian)(dian)(dian)(dian)(dian)量大(da)的(de)電(dian)(dian)(dian)(dian)(dian)器(qi)如相機、玩具汽車(che)、剃須(xu)刀等(deng)購(gou)買(mai)電(dian)(dian)(dian)(dian)(dian)池(chi)，建議(yi)考(kao)慮充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)和堿(jian)性(xing)電(dian)(dian)(dian)(dian)(dian)池(chi)，這時(shi)最好不(bu)要貪(tan)便宜(yi)買(mai)碳性(xing)電(dian)(dian)(dian)(dian)(dian)池(chi)。對于耗(hao)電(dian)(dian)(dian)(dian)(dian)量低(di)的(de)遙控器(qi)、鐘表(biao)、收音機等(deng)，便宜(yi)的(de)碳性(xing)電(dian)(dian)(dian)(dian)(dian)池(chi)足夠(gou)。家里有終止(zhi)電(dian)(dian)(dian)(dian)(dian)壓(ya)較高的(de)電(dian)(dian)(dian)(dian)(dian)器(qi)，推薦購(gou)買(mai)優(you)質的(de)堿(jian)性(xing)電(dian)(dian)(dian)(dian)(dian)池(chi)或充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)。

（1）充(chong)(chong)電電池到(dao)手后，需(xu)要反復(fu)充(chong)(chong)放3-4次，才能充(chong)分激活電池，達到最佳使用(yong)(yong)狀態。首(shou)次充(chong)電前，最好把余電用(yong)(yong)完，首(shou)次充(chong)電的時間(jian)可以比(bi)建議充(chong)電時間(jian)稍長。充(chong)電時最好一次性充(chong)滿，不要充(chong)一下(xia)用(yong)(yong)一下(xia)又接(jie)著充(chong)。

（2）電(dian)(dian)(dian)池使用和充(chong)電(dian)(dian)(dian)時(shi)一定(ding)把正負極對好，否則(ze)可能燒壞電(dian)(dian)(dian)池或者電(dian)(dian)(dian)器。不要嘗試(shi)給一次性電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)。

（3）需要同時使(shi)用(yong)多節(jie)電(dian)池時，最(zui)好選(xuan)擇容量和(he)(he)狀態(tai)一致的電(dian)池，道理和(he)(he)短板效應一致。例如，最(zui)好不同時使(shi)用(yong)1300毫(hao)安(an)時和1800毫安時的電(dian)池，不同時使用(yong)新(xin)電(dian)池和老電(dian)池，否(fou)則將會降低大容量電(dian)池或者新(xin)電(dian)池的效用(yong)。

（4）充電(dian)時(shi)(shi)充電(dian)器(qi)和電(dian)池(chi)發(fa)熱是正常的，所以充電(dian)時(shi)(shi)請注意周圍不要有易(yi)燃易(yi)爆物品。如果充電(dian)器(qi)和電(dian)池(chi)時(shi)(shi)過于發(fa)燙(tang)，可以先拔掉電(dian)源(yuan)停止(zhi)充電(dian)，等待溫度下降后，再充電(dian)。

（5）如果一(yi)段時間(jian)不使(shi)用電池(chi)(chi)，建議把(ba)電池(chi)(chi)拿出來，將電池(chi)(chi)和(he)充電器(qi)放(fang)(fang)置(zhi)在干燥(zao)地方存放(fang)(fang)，用電池(chi)(chi)盒存放(fang)(fang)電池(chi)(chi)最(zui)好。電池(chi)(chi)放(fang)(fang)置(zhi)時注意(yi)不要短路，有個客戶曾經把(ba)電池(chi)(chi)和(he)一(yi)大串鑰匙放(fang)(fang)在一(yi)起，結果導致短路，電池(chi)(chi)損壞。

（6）從(cong)充(chong)電(dian)器(qi)(qi)里(li)取放(fang)電(dian)池時，注意(yi)輕拿輕放(fang)。如果(guo)從(cong)充(chong)電(dian)器(qi)(qi)里(li)野蠻地摳(kou)放(fang)電(dian)池，會(hui)很快損壞電(dian)池膠腸，影響電(dian)池壽(shou)命。這點KTV客戶(hu)特別要謹記。
