（1）充電電池的容量

消費者要(yao)(yao)根據電(dian)(dian)(dian)(dian)器耗電(dian)(dian)(dian)(dian)量大小來(lai)購(gou)買電(dian)(dian)(dian)(dian)池(chi)(chi)。電(dian)(dian)(dian)(dian)容量越大的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)，瞬(shun)間工作電(dian)(dian)(dian)(dian)流大，因此對電(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)路的(de)要(yao)(yao)求高，搞(gao)不好會燒壞電(dian)(dian)(dian)(dian)路。同時(shi)對電(dian)(dian)(dian)(dian)池(chi)(chi)自身的(de)損耗也大。電(dian)(dian)(dian)(dian)容量大的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)，充電(dian)(dian)(dian)(dian)循環次(ci)數相對要(yao)(yao)少，也就是(shi)壽命相對較短。

因此，耗(hao)電(dian)量中等以(yi)下的(de)(de)電(dian)器(qi)(qi)，如mp3、無線鼠標、小型玩(wan)具、手電(dian)筒等，選用1300-1800毫(hao)安時(shi)的(de)(de)5號(hao)電(dian)池或者600-800毫(hao)安時(shi)的(de)(de)7號(hao)電(dian)池就(jiu)可以(yi)，耗(hao)電(dian)量大的(de)(de)電(dian)器(qi)(qi)，如相機、剃須刀、電(dian)動牙刷(shua)、話筒、玩(wan)具汽車、航模(mo)等，需要選用2000-2600毫(hao)安時(shi)的(de)(de)5號(hao)電(dian)池或850-1000毫(hao)安時(shi)的(de)(de)7號(hao)電(dian)池。

（2）充電電池的自放電

充(chong)電(dian)(dian)電(dian)(dian)池(chi)放(fang)(fang)置一段時間后，電(dian)(dian)量會逐漸減少，稱之為自放(fang)(fang)電(dian)(dian)。品質不好的電(dian)(dian)池(chi)，自放(fang)(fang)電(dian)(dian)現象(xiang)嚴重。這樣(yang)，為了滿足使用(yong)(yong)，充(chong)電(dian)(dian)電(dian)(dian)池(chi)需(xu)要頻繁充(chong)電(dian)(dian)，從(cong)而降(jiang)低(di)了電(dian)(dian)池(chi)使用(yong)(yong)壽(shou)命(ming)。

低自放(fang)電(dian)(dian)(dian)充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)也就應運而生。品質優異的低自放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)，據說放(fang)置2年后，還(huan)能保持80%以上的電量，大大方(fang)便了消費者的日常(chang)使用，也提高(gao)(gao)了電池(chi)的使用周期。當然，低自放(fang)電池(chi)的價(jia)格會高(gao)(gao)于普通充電電池(chi)。

如果(guo)使用充(chong)(chong)電(dian)電(dian)池不是很頻(pin)繁，使用一(yi)次電(dian)池后會放置(zhi)一(yi)段(duan)時間，建議考慮購買(mai)低自放電(dian)電(dian)池。若使用充(chong)(chong)電(dian)電(dian)池的頻(pin)率(lv)很高(gao)，購買(mai)普通充(chong)(chong)電(dian)電(dian)池就可以(yi)了(le)。

（3）電池類型的選擇

如果需要為耗電(dian)(dian)量(liang)大的(de)電(dian)(dian)器如相機、玩具汽車、剃(ti)須刀等(deng)購(gou)買(mai)電(dian)(dian)池(chi)(chi)，建議考(kao)慮充電(dian)(dian)電(dian)(dian)池(chi)(chi)和堿(jian)性(xing)電(dian)(dian)池(chi)(chi)，這時最好不要貪便(bian)宜(yi)買(mai)碳性(xing)電(dian)(dian)池(chi)(chi)。對于耗電(dian)(dian)量(liang)低的(de)遙控器、鐘表(biao)、收音機等(deng)，便(bian)宜(yi)的(de)碳性(xing)電(dian)(dian)池(chi)(chi)足夠。家里有終止電(dian)(dian)壓(ya)較高的(de)電(dian)(dian)器，推薦購(gou)買(mai)優質(zhi)的(de)堿(jian)性(xing)電(dian)(dian)池(chi)(chi)或充電(dian)(dian)電(dian)(dian)池(chi)(chi)。

（1）充電電池到手后，需要(yao)反復充放3-4次(ci)，才能充(chong)(chong)分激活(huo)電(dian)池(chi)，達到最(zui)(zui)佳使用(yong)狀態(tai)。首次(ci)充(chong)(chong)電(dian)前，最(zui)(zui)好把余電(dian)用(yong)完，首次(ci)充(chong)(chong)電(dian)的(de)時間(jian)(jian)可以(yi)比建議(yi)充(chong)(chong)電(dian)時間(jian)(jian)稍(shao)長。充(chong)(chong)電(dian)時最(zui)(zui)好一次(ci)性(xing)充(chong)(chong)滿，不要充(chong)(chong)一下用(yong)一下又接(jie)著充(chong)(chong)。

（2）電(dian)池(chi)使(shi)用和(he)充(chong)電(dian)時(shi)一(yi)定把正負極(ji)對(dui)好，否則可能燒(shao)壞電(dian)池(chi)或者(zhe)電(dian)器。不要嘗試(shi)給(gei)一(yi)次性電(dian)池(chi)充(chong)電(dian)。

（3）需要同時(shi)使用(yong)多節(jie)電池時(shi)，最(zui)好(hao)選擇容量和狀態(tai)一致的電池，道理和短板效應一致。例如，最(zui)好(hao)不同時(shi)使用(yong)1300毫安時和1800毫安時的(de)電池，不同(tong)時使(shi)用(yong)新(xin)電池和(he)老電池，否則將會(hui)降低大容量電池或者新(xin)電池的(de)效用(yong)。

（4）充(chong)電(dian)時(shi)充(chong)電(dian)器(qi)和電(dian)池發(fa)熱是正常的，所以(yi)充(chong)電(dian)時(shi)請注意周圍(wei)不要(yao)有易(yi)燃易(yi)爆(bao)物品。如果充(chong)電(dian)器(qi)和電(dian)池時(shi)過于發(fa)燙，可(ke)以(yi)先(xian)拔掉電(dian)源(yuan)停止充(chong)電(dian)，等待(dai)溫度(du)下降后，再充(chong)電(dian)。

（5）如果(guo)一(yi)段時(shi)間不(bu)使(shi)用(yong)電(dian)(dian)池(chi)，建議(yi)把(ba)電(dian)(dian)池(chi)拿出來(lai)，將電(dian)(dian)池(chi)和(he)充電(dian)(dian)器放置在干燥地方存(cun)(cun)放，用(yong)電(dian)(dian)池(chi)盒(he)存(cun)(cun)放電(dian)(dian)池(chi)最好。電(dian)(dian)池(chi)放置時(shi)注意(yi)不(bu)要(yao)短路(lu)(lu)，有個客戶曾經把(ba)電(dian)(dian)池(chi)和(he)一(yi)大(da)串鑰匙放在一(yi)起，結(jie)果(guo)導(dao)致短路(lu)(lu)，電(dian)(dian)池(chi)損(sun)壞(huai)。

（6）從充電(dian)(dian)(dian)(dian)器里(li)(li)取放(fang)(fang)電(dian)(dian)(dian)(dian)池(chi)(chi)時，注意輕拿輕放(fang)(fang)。如果從充電(dian)(dian)(dian)(dian)器里(li)(li)野蠻地(di)摳(kou)放(fang)(fang)電(dian)(dian)(dian)(dian)池(chi)(chi)，會(hui)很快(kuai)損壞電(dian)(dian)(dian)(dian)池(chi)(chi)膠腸，影響電(dian)(dian)(dian)(dian)池(chi)(chi)壽命。這點KTV客戶特別(bie)要謹記。
