一、18650锂电池的尺寸之谜：它和通俗电池有啥差别？
的(de)“18650”实(shi)在(zai)是它的(de)尺(chi)寸(cun)暗码——直径(jing)18毫(hao)(hao)米、长(zhang)度65毫(hao)(hao)米，0代表(biao)圆柱形设(she)想。这类尺(chi)寸(cun)设(she)想让它成为电(dian)子装备(bei)的(de)“能量小钢炮(pao)”，比罕(han)见的(de)5号(hao)(hao)电(dian)池(chi)（AA型，直径(jing)14毫(hao)(hao)米、长(zhang)度50毫(hao)(hao)米）更(geng)粗更(geng)长(zhang)，能量密度也更(geng)高。举(ju)个例(li)子：一节18650锂电(dian)池(chi)的(de)容量凡是是2000-4000mAh，而5号(hao)(hao)电(dian)池(chi)容量大多在(zai)800-1500mAh之间，差异(yi)较着。
二、充电体例大揭秘：18650锂电池怎样“回血”？
给18650锂电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)电(dian)(dian)(dian)(dian)可不能(neng)随意用充(chong)(chong)电(dian)(dian)(dian)(dian)器！它须要(yao)公用锂电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)电(dian)(dian)(dian)(dian)器，这类充(chong)(chong)电(dian)(dian)(dian)(dian)器能(neng)精(jing)准(zhun)节制电(dian)(dian)(dian)(dian)压(ya)（凡是4.2V）和电(dian)(dian)(dian)(dian)流(liu)（按照电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)容量调剂，比方1A或(huo)2A），防止过(guo)充(chong)(chong)致使电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)收(shou)缩乃至爆炸。若是用通(tong)俗镍氢电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)电(dian)(dian)(dian)(dian)器（输(shu)入电(dian)(dian)(dian)(dian)压(ya)1.4V摆(bai)布），底子充(chong)(chong)不了；用高(gao)压(ya)充(chong)(chong)电(dian)(dian)(dian)(dian)器（比方给手(shou)机充(chong)(chong)电(dian)(dian)(dian)(dian)的5V充(chong)(chong)电(dian)(dian)(dian)(dian)器），则会间接破坏电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。宁静充(chong)(chong)电(dian)(dian)(dian)(dian)三因素：选对充(chong)(chong)电(dian)(dian)(dian)(dian)器、别(bie)混用差别(bie)型号电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、充(chong)(chong)电(dian)(dian)(dian)(dian)时阔别(bie)低温(wen)情(qing)况。
三、充电注重事变：这些坑万万别踩！
18650锂电池充电有(you)“三不准绳”：
不(bu)(bu)假冒：差别品牌、容量的电池别一路充(chong)(chong)(chong)(chong)，不(bu)(bu)然充(chong)(chong)(chong)(chong)电速(su)率不(bu)(bu)分歧，轻易(yi)过充(chong)(chong)(chong)(chong)或欠充(chong)(chong)(chong)(chong)；
不留宿(su)：充(chong)电时(shi)候节制(zhi)在3-5小时(shi)（按照(zhao)电池容量(liang)和充(chong)电器(qi)电流），布(bu)满后实时(shi)拔掉，防(fang)止永劫候浮充(chong)；
不(bu)破(po)坏：若是电池外(wai)壳(qiao)有凸起(qi)、漏液(ye)，万万别充(chong)电！这类电池外(wai)部能够短(duan)路，充(chong)电时能够动怒。
小贴士：充电时把电池放(fang)在防火(huo)容器里（比方陶瓷碗(wan)），万一出题目能削减(jian)丧失。
