挂(gua)卡锂电(dian)(dian)池(chi)(chi)(chi)无记(ji)忆效应，很(hen)多小伙伴喜欢将电(dian)(dian)池(chi)(chi)(chi)电(dian)(dian)量(liang)耗尽再充(chong)电(dian)(dian)，认为这是一种(zhong)电(dian)(dian)池(chi)(chi)(chi)激活的方(fang)式(shi)，其(qi)实不然。这种(zhong)将电(dian)(dian)池(chi)(chi)(chi)的电(dian)(dian)量(liang)耗尽再充(chong)电(dian)(dian)的情况称之(zhi)为深度充(chong)放电(dian)(dian)。

深度充(chong)放电(dian)(dian)(dian)是大多数人使(shi)用挂卡锂电(dian)(dian)(dian)池的(de)一个重要误解(jie)。实验数据表明，深度充(chong)放电(dian)(dian)(dian)的(de)次数在其他不变的(de)环境(jing)和电(dian)(dian)(dian)池寿命(ming)成正比，多次充(chong)放电(dian)(dian)(dian)会导(dao)致电(dian)(dian)(dian)池寿命(ming)大大缩短，还容易造(zao)成电(dian)(dian)(dian)池膨胀等情况，严重的(de)话还会爆炸。

挂卡锂电(dian)(dian)池(chi)的(de)过(guo)充(chong)和(he)充(chong)放(fang)电(dian)(dian)流(liu)大(da)的(de)情(qing)(qing)况(kuang)，有可(ke)能是电(dian)(dian)池(chi)保护(hu)板设(she)计不(bu)合理(li)所导(dao)致。习惯(guan)将电(dian)(dian)池(chi)充(chong)满电(dian)(dian)后仍继续充(chong)电(dian)(dian)一段时(shi)间，长时(shi)间的(de)过(guo)充(chong)和(he)过(guo)放(fang)会严重(zhong)伤害和(he)破(po)坏锂电(dian)(dian)池(chi)的(de)性能，严重(zhong)的(de)话可(ke)引起爆炸等极端情(qing)(qing)况(kuang)。

挂(gua)卡(ka)锂电(dian)池(chi)在充(chong)放电(dian)时，充(chong)电(dian)器(qi)(qi)的(de)电(dian)流与用电(dian)器(qi)(qi)的(de)一(yi)般(ban)电(dian)流负载应在规定范围内。过大的(de)电(dian)流负载容易(yi)造(zao)成电(dian)池(chi)内部短路，从(cong)而破坏锂离子(zi)，造(zao)成电(dian)路的(de)安(an)全(quan)隐患。这同样(yang)适用于(yu)可(ke)充(chong)电(dian)充(chong)电(dian)器(qi)(qi)的(de)电(dian)压。所(suo)以在我(wo)们使用充(chong)电(dian)器(qi)(qi)的(de)时候，也要(yao)注(zhu)意看充(chong)电(dian)器(qi)(qi)是否合格(ge)。

工作环境(jing)对(dui)挂卡锂电(dian)(dian)池(chi)来说一样重要。如果长时(shi)(shi)间在冰点(dian)以(yi)下(xia)使(shi)用，可能会对(dui)电(dian)(dian)池(chi)寿命造成很大(da)的(de)伤害。如果长时(shi)(shi)间放置在过(guo)热的(de)环境(jing)中，电(dian)(dian)池(chi)的(de)寿命会大(da)大(da)降低(di)。在严重的(de)情况(kuang)下(xia)，内部压力的(de)增(zeng)加(jia)会引发(fa)爆炸(zha)。即使(shi)没有(you)爆炸(zha)，电(dian)(dian)池(chi)在高(gao)温(wen)下(xia)也会迅速报废。
