一、18650鋰電池的壽命有多長

18650鋰電池的(de)使(shi)用壽(shou)命都只在(zai)三年~五(wu)年。

18650鋰電(dian)(dian)池普(pu)遍(bian)都有著(zhu)容量(liang)大、壽命(ming)(ming)長、安(an)全性能高，3.7V的(de)18650鋰(li)電(dian)(dian)池一(yi)般循(xun)環(huan)壽命(ming)(ming)可達500~1000次左右，3.2V的(de)18650一(yi)般壽命(ming)(ming)可達2000以(yi)上。最好對鋰(li)電(dian)(dian)池進行部分放(fang)電(dian)(dian)，而不(bu)是完(wan)全放(fang)電(dian)(dian)，并(bing)且(qie)要盡量(liang)避免經(jing)常的(de)完(wan)全放(fang)電(dian)(dian)。

二、18650鋰電池如何保養

很多人以為(wei)18650只要充一(yi)次(ci)(ci)或用(yong)一(yi)次(ci)(ci)就算(suan)循環充電(dian)(dian)(dian)(dian)(dian)(dian)，其(qi)(qi)實這是(shi)(shi)一(yi)個誤區，循環充電(dian)(dian)(dian)(dian)(dian)(dian)其(qi)(qi)實是(shi)(shi)指完全(quan)重放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)的次(ci)(ci)數，鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池不同于鎳(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)池，鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池不具有任(ren)何記(ji)憶效應，隨(sui)時隨(sui)地可以充電(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)池有余電(dian)(dian)(dian)(dian)(dian)(dian)的情(qing)況下進行(xing)充電(dian)(dian)(dian)(dian)(dian)(dian)不但不會縮(suo)短使用(yong)壽命(ming)，還能對電(dian)(dian)(dian)(dian)(dian)(dian)池進行(xing)保養，延長其(qi)(qi)循環使用(yong)周期，對于鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池，正確(que)的做法(fa)是(shi)(shi)緩充而不是(shi)(shi)深充。

想要延長18650鋰(li)電池壽命，就得遵(zun)守以下幾點：

1、不要在極端的環境下使用，鋰電池怕冷也怕熱

理(li)論上(shang)溫度在-20℃-55℃之間(jian)可以正(zheng)常使用(yong)，日常生活中，使用(yong)溫度在5℃-35℃之間(jian)對鋰(li)電(dian)池是沒(mei)有傷害的(de)，北(bei)方的(de)用(yong)戶(hu)冬(dong)天盡可能把鋰(li)電(dian)池取(qu)回(hui)家里存放(fang)(fang)，不要放(fang)(fang)到室外，南方的(de)用(yong)戶(hu)避免夏天暴曬。

2、鋰電池不要經常深度充放電

這個我們剛剛講了，對于鋰電池，正確的做法(fa)是緩充而不是深充。
