（1）充電電池的容量

消費者要(yao)根據(ju)電(dian)器耗電(dian)量(liang)大小來購買(mai)電(dian)池(chi)。電(dian)容量(liang)越(yue)大的電(dian)池(chi)，瞬(shun)間工作電(dian)流大，因(yin)此對電(dian)器電(dian)路的要(yao)求(qiu)高，搞(gao)不好會燒壞電(dian)路。同時對電(dian)池(chi)自身的損耗也(ye)大。電(dian)容量(liang)大的電(dian)池(chi)，充電(dian)循環次數相對要(yao)少，也(ye)就是壽命相對較短。

因此，耗(hao)電(dian)(dian)(dian)量中等以下的(de)(de)電(dian)(dian)(dian)器，如(ru)mp3、無線鼠(shu)標、小型玩(wan)具、手電(dian)(dian)(dian)筒等，選用1300-1800毫安(an)(an)時的(de)(de)5號(hao)電(dian)(dian)(dian)池或者600-800毫安(an)(an)時的(de)(de)7號(hao)電(dian)(dian)(dian)池就可以，耗(hao)電(dian)(dian)(dian)量大的(de)(de)電(dian)(dian)(dian)器，如(ru)相(xiang)機、剃須刀、電(dian)(dian)(dian)動牙刷、話筒、玩(wan)具汽(qi)車、航模等，需要選用2000-2600毫安(an)(an)時的(de)(de)5號(hao)電(dian)(dian)(dian)池或850-1000毫安(an)(an)時的(de)(de)7號(hao)電(dian)(dian)(dian)池。

（2）充電電池的自放電

充(chong)電(dian)電(dian)池(chi)放(fang)(fang)置一段時間(jian)后，電(dian)量(liang)會(hui)逐漸減少，稱之為(wei)自放(fang)(fang)電(dian)。品質不(bu)好(hao)的電(dian)池(chi)，自放(fang)(fang)電(dian)現象嚴(yan)重。這樣，為(wei)了滿足使用(yong)，充(chong)電(dian)電(dian)池(chi)需要頻繁充(chong)電(dian)，從而降低了電(dian)池(chi)使用(yong)壽命。

低自(zi)放電(dian)充電(dian)電(dian)池也(ye)就應運(yun)而生。品質優異(yi)的低自(zi)放電(dian)電(dian)池，據說放置2年(nian)后，還能保持(chi)80%以上的(de)(de)電(dian)量，大(da)大(da)方(fang)便了(le)消(xiao)費者的(de)(de)日常使用(yong)，也提高了(le)電(dian)池的(de)(de)使用(yong)周期(qi)。當然，低自(zi)放電(dian)池的(de)(de)價格會(hui)高于普通充電(dian)電(dian)池。

如果使用充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)不是(shi)很頻(pin)繁，使用一(yi)次(ci)電(dian)(dian)(dian)池(chi)后會放置一(yi)段時間，建議考慮購買低自(zi)放電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)。若使用充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)的頻(pin)率很高，購買普通(tong)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)就可以了。

（3）電池類型的選擇

如果(guo)需要為耗(hao)電(dian)量(liang)大的電(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(xing)(xing)(xing)電(dian)池(chi)，這時最好不要貪便宜買碳(tan)性(xing)(xing)(xing)電(dian)池(chi)。對于(yu)耗(hao)電(dian)量(liang)低的遙控器(qi)、鐘表、收音機等，便宜的碳(tan)性(xing)(xing)(xing)電(dian)池(chi)足(zu)夠。家(jia)里有終止電(dian)壓較高的電(dian)器(qi)，推薦購買優質(zhi)的堿性(xing)(xing)(xing)電(dian)池(chi)或充電(dian)電(dian)池(chi)。

（1）充(chong)電電池(chi)到(dao)手(shou)后，需要反復充(chong)放3-4次(ci)，才能充(chong)分激活(huo)電(dian)池，達到最(zui)佳(jia)使(shi)用(yong)狀(zhuang)態。首次(ci)充(chong)電(dian)前，最(zui)好(hao)把(ba)余電(dian)用(yong)完，首次(ci)充(chong)電(dian)的時間可以比建議(yi)充(chong)電(dian)時間稍長。充(chong)電(dian)時最(zui)好(hao)一次(ci)性(xing)充(chong)滿，不要充(chong)一下用(yong)一下又接(jie)著充(chong)。

（2）電池(chi)使(shi)用(yong)和(he)充(chong)電時一(yi)定把(ba)正(zheng)負極對好，否則可能燒壞電池(chi)或者電器。不(bu)要(yao)嘗試給一(yi)次(ci)性電池(chi)充(chong)電。

（3）需要同時使用多節電池(chi)時，最好選擇(ze)容量和(he)狀(zhuang)態一致的電池(chi)，道理和(he)短板效應一致。例如，最好不同時使用1300毫安時(shi)和1800毫安(an)時的電池(chi)，不同時使(shi)用新電池(chi)和老(lao)電池(chi)，否則將會(hui)降低大容(rong)量(liang)電池(chi)或(huo)者新電池(chi)的效(xiao)用。

（4）充(chong)電(dian)(dian)時充(chong)電(dian)(dian)器(qi)和電(dian)(dian)池(chi)發熱是正(zheng)常的，所以充(chong)電(dian)(dian)時請(qing)注意周圍不要(yao)有(you)易(yi)燃易(yi)爆(bao)物品。如果充(chong)電(dian)(dian)器(qi)和電(dian)(dian)池(chi)時過于發燙，可以先拔掉電(dian)(dian)源停止充(chong)電(dian)(dian)，等(deng)待溫度下降后，再充(chong)電(dian)(dian)。

（5）如果(guo)一(yi)段時間(jian)不使用(yong)電池(chi)，建(jian)議(yi)把(ba)電池(chi)拿出來，將電池(chi)和充電器放(fang)置在干燥地(di)方存(cun)放(fang)，用(yong)電池(chi)盒存(cun)放(fang)電池(chi)最好。電池(chi)放(fang)置時注(zhu)意不要短路，有(you)個客戶曾經把(ba)電池(chi)和一(yi)大(da)串鑰匙(chi)放(fang)在一(yi)起，結(jie)果(guo)導致短路，電池(chi)損壞。

（6）從充(chong)電(dian)(dian)(dian)器(qi)里(li)取放(fang)電(dian)(dian)(dian)池(chi)時，注(zhu)意輕拿輕放(fang)。如果從充(chong)電(dian)(dian)(dian)器(qi)里(li)野蠻地(di)摳放(fang)電(dian)(dian)(dian)池(chi)，會很快損壞電(dian)(dian)(dian)池(chi)膠腸，影響(xiang)電(dian)(dian)(dian)池(chi)壽命。這點KTV客(ke)戶(hu)特別要謹記。
