一、18650锂电池的尺寸之谜：它和通俗电池有啥差别？
18650锂电池(chi)(chi)的“18650”实在(zai)是它(ta)的尺寸暗码——直(zhi)径18毫米(mi)(mi)(mi)(mi)、长度(du)(du)65毫米(mi)(mi)(mi)(mi)，0代表圆柱形设想。这类尺寸设想让它(ta)成为(wei)电子装备的“能(neng)(neng)量(liang)小钢炮”，比罕见的5号电池(chi)(chi)（AA型，直(zhi)径14毫米(mi)(mi)(mi)(mi)、长度(du)(du)50毫米(mi)(mi)(mi)(mi)）更(geng)(geng)粗更(geng)(geng)长，能(neng)(neng)量(liang)密(mi)度(du)(du)也更(geng)(geng)高。举个例子：一节18650锂电池(chi)(chi)的容(rong)量(liang)凡(fan)是是2000-3500mAh，而5号电池(chi)(chi)容(rong)量(liang)大多在(zai)800-2000mAh之间，差异较着。
二、充电体例大揭秘：18650锂电池(chi)怎样“回血(xue)”？
给18650锂(li)(li)电(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)可不(bu)能(neng)随意用充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)器(qi)！它须要(yao)公用锂(li)(li)电(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)器(qi)，这类充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)器(qi)能(neng)精准节制电(dian)(dian)(dian)(dian)压(ya)(ya)（凡是4.2V）和电(dian)(dian)(dian)(dian)流(liu)（按照(zhao)电(dian)(dian)(dian)(dian)池(chi)(chi)容(rong)量调剂，比方(fang)1A或2A），防止过(guo)充(chong)(chong)(chong)致使电(dian)(dian)(dian)(dian)池(chi)(chi)收缩乃至爆炸。若是用通(tong)俗镍氢电(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)器(qi)（输入电(dian)(dian)(dian)(dian)压(ya)(ya)1.4V摆布），底子充(chong)(chong)(chong)不(bu)满；用高压(ya)(ya)充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)器(qi)（比方(fang)给手(shou)机充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)的5V充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)器(qi)），则会间接破坏电(dian)(dian)(dian)(dian)池(chi)(chi)。宁静充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)三(san)因素：选对充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)器(qi)、别混用差(cha)别型号电(dian)(dian)(dian)(dian)池(chi)(chi)、充(chong)(chong)(chong)电(dian)(dian)(dian)(dian)时阔别低温情况。
三、充电注重(zhong)事变：这些坑万万别踩！
18650锂电池充电有“三(san)不准绳”：
不(bu)假冒：差别品牌、容量的电(dian)池别一(yi)路充(chong)，不(bu)然充(chong)电(dian)速率(lv)不(bu)分歧，轻易过充(chong)或(huo)欠充(chong)；
不留宿(su)：充(chong)电(dian)(dian)时候节制在3-5小时（按照电(dian)(dian)池容量和(he)充(chong)电(dian)(dian)器电(dian)(dian)流），布满后实(shi)时拔掉，防(fang)止(zhi)永劫候浮充(chong)；
不破(po)坏：若(ruo)是电(dian)池外(wai)壳有(you)凸起(qi)、漏液，万(wan)万(wan)别充(chong)电(dian)！这(zhei)类(lei)电(dian)池外(wai)部能(neng)够短(duan)路，充(chong)电(dian)时能(neng)够动怒。
小贴(tie)士：充电时把电池放在防火(huo)容器里(li)（比方(fang)陶瓷(ci)碗），万一出题目能削减丧失。
