一、強光手電筒一定要用匹配的鋰電池

用作強光手電(dian)筒(tong)光源(yuan)的(de)(de)鋰(li)(li)電(dian)池有較多(duo)型(xing)號(hao)，常用的(de)(de)有18650、17670、16340等，首(shou)先我(wo)們要認(ren)識這些型(xing)號(hao)表(biao)達的(de)(de)意思，電(dian)池型(xing)號(hao)前(qian)面兩位數表(biao)示(shi)的(de)(de)是電(dian)池直(zhi)徑(jing)(jing)，后面三位數表(biao)示(shi)高(gao)度(du)。以市場(chang)應(ying)用最(zui)成(cheng)熟的(de)(de)18650鋰(li)(li)電(dian)池來說，其直(zhi)徑(jing)(jing)是18mm，高(gao)度(du)是65mm；而手電(dian)筒(tong)用的(de)(de)16340電(dian)池則是指直(zhi)徑(jing)(jing)16mm，高(gao)度(du)為34mm的(de)(de)鋰(li)(li)電(dian)池。

既(ji)定電壓和放電電流的手電筒燈泡(pao)要求(qiu)鋰電池不能過流，更(geng)不能超(chao)壓。

對(dui)于0.85A的(de)燈泡(pao)來說，放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)最(zui)(zui)好是(shi)0.85A，如果電(dian)(dian)(dian)(dian)流(liu)(liu)過(guo)(guo)小(xiao)，手電(dian)(dian)(dian)(dian)筒可(ke)能(neng)(neng)會(hui)亮度不(bu)夠，如果電(dian)(dian)(dian)(dian)流(liu)(liu)過(guo)(guo)大，又可(ke)能(neng)(neng)因過(guo)(guo)流(liu)(liu)而損(sun)壞電(dian)(dian)(dian)(dian)池(chi)結(jie)構，所以，“匹配”最(zui)(zui)好，既能(neng)(neng)獲得最(zui)(zui)大的(de)亮度，也不(bu)會(hui)損(sun)害(hai)電(dian)(dian)(dian)(dian)池(chi)。比如，給0.85A的(de)燈泡(pao)供電(dian)(dian)(dian)(dian)，友來16340鋰電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)就(jiu)不(bu)行，可(ke)能(neng)(neng)會(hui)在(zai)亮過(guo)(guo)幾分(fen)鐘之(zhi)后突然(ran)變暗，如果采用具(ju)有較(jiao)大電(dian)(dian)(dian)(dian)流(liu)(liu)放(fang)電(dian)(dian)(dian)(dian)性能(neng)(neng)的(de)雷鷹16340鋰電(dian)(dian)(dian)(dian)池(chi)，放(fang)電(dian)(dian)(dian)(dian)效果就(jiu)會(hui)好許多。

7.2V燈泡(pao)(pao)(pao)應該使用(yong)兩只鋰(li)電(dian)(dian)池(chi)(chi)(chi)串聯(lian)供(gong)電(dian)(dian)，因(yin)為(wei)鋰(li)電(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)額(e)定電(dian)(dian)壓(ya)(ya)是3.6V~3.7V，兩只3.6V電(dian)(dian)池(chi)(chi)(chi)串聯(lian)起來就是7.2V，另一方面(mian)，如(ru)(ru)果鋰(li)電(dian)(dian)池(chi)(chi)(chi)串聯(lian)起來的(de)(de)(de)(de)電(dian)(dian)壓(ya)(ya)高(gao)于燈泡(pao)(pao)(pao)電(dian)(dian)壓(ya)(ya)過(guo)多的(de)(de)(de)(de)話(hua)，這就是超壓(ya)(ya)運(yun)行，會導致燈泡(pao)(pao)(pao)被燒(shao)，所以(yi)，以(yi)前使用(yong)鎳氫電(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)手電(dian)(dian)筒，如(ru)(ru)果換(huan)成鋰(li)電(dian)(dian)池(chi)(chi)(chi)一定要換(huan)燈泡(pao)(pao)(pao)，超壓(ya)(ya)運(yun)行可以(yi)使手電(dian)(dian)筒量度更(geng)高(gao)，但負面(mian)的(de)(de)(de)(de)作(zuo)用(yong)就是可能燒(shao)掉燈泡(pao)(pao)(pao)，得不償失，因(yin)此選擇手電(dian)(dian)筒一定要用(yong)6V以(yi)上的(de)(de)(de)(de)燈泡(pao)(pao)(pao)。

最后，就是(shi)(shi)(shi)手電(dian)(dian)(dian)(dian)筒鋰電(dian)(dian)(dian)(dian)池的(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，鋰電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)(shi)(shi)根據電(dian)(dian)(dian)(dian)壓值判斷電(dian)(dian)(dian)(dian)池是(shi)(shi)(shi)否滿電(dian)(dian)(dian)(dian)的(de)(de)(de)，單節鋰電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)終止(zhi)電(dian)(dian)(dian)(dian)壓是(shi)(shi)(shi)4.2V，你只要買的(de)(de)(de)是(shi)(shi)(shi)正宗充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)就會自動(dong)充(chong)(chong)(chong)(chong)到4.2V，然后停止(zhi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)行為。這里強(qiang)調(diao)指出(chu)，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)正宗很重要。

二、強光手電筒鋰電池使用誤區

誤區一：鋰電池的“用盡、充滿”基本原則

不(bu)可否認，強光手電(dian)筒鋰(li)電(dian)池(chi)(chi)也有(you)記(ji)憶(yi)效(xiao)(xiao)應，但其記(ji)憶(yi)效(xiao)(xiao)應是微(wei)乎其微(wei)的(de)，連制造商對(dui)(dui)此記(ji)憶(yi)效(xiao)(xiao)應都(dou)忽略不(bu)記(ji)，因(yin)此，在一(yi)(yi)些(xie)對(dui)(dui)鋰(li)電(dian)池(chi)(chi)產品(pin)的(de)廣告中，可以(yi)看(kan)到廠商是打出“沒有(you)記(ji)憶(yi)效(xiao)(xiao)應，隨(sui)用(yong)隨(sui)充”的(de)牌子。但在實際使用(yong)中，大家也許會(hui)(hui)發覺，鋰(li)電(dian)池(chi)(chi)使用(yong)的(de)時間會(hui)(hui)越來(lai)越短。這是怎么回事(shi)呢？其實，鋰(li)電(dian)池(chi)(chi)的(de)制作(zuo)材(cai)(cai)料(liao)是一(yi)(yi)種活(huo)性物質，活(huo)性物質都(dou)會(hui)(hui)老(lao)化(hua)。而(er)制作(zuo)鋰(li)電(dian)池(chi)(chi)的(de)材(cai)(cai)料(liao)，對(dui)(dui)于使用(yong)頻繁的(de)程度和使用(yong)環境、溫度等(deng)等(deng)條件都(dou)比較敏感。

一般led手(shou)電(dian)(dian)(dian)(dian)筒鋰電(dian)(dian)(dian)(dian)池(chi)的(de)使用壽命(ming)是充放電(dian)(dian)(dian)(dian)300～500次，電(dian)(dian)(dian)(dian)池(chi)的(de)自(zi)然損耗會(hui)明(ming)顯(xian)縮短電(dian)(dian)(dian)(dian)池(chi)的(de)持續使用時間。而對過(guo)(guo)度的(de)充電(dian)(dian)(dian)(dian)和(he)過(guo)(guo)度的(de)放電(dian)(dian)(dian)(dian)，都(dou)會(hui)急速的(de)消(xiao)減(jian)電(dian)(dian)(dian)(dian)池(chi)活性，直接導(dao)致鋰電(dian)(dian)(dian)(dian)池(chi)的(de)快速老(lao)化(hua)。很多手(shou)機用戶可能都(dou)有這樣的(de)經歷(li)，明(ming)明(ming)顯(xian)示還(huan)有一格電(dian)(dian)(dian)(dian)量(liang)，可半個小時后，就(jiu)會(hui)顯(xian)示“電(dian)(dian)(dian)(dian)量(liang)低”，有時候還(huan)會(hui)自(zi)動關機。

所以(yi)在平時使(shi)用(yong)(yong)時，我們不必遵(zun)循“用(yong)(yong)盡、充滿”的(de)基本(ben)原則(ze)。如(ru)果(guo)在檢(jian)測電(dian)路對電(dian)池(chi)檢(jian)測不準的(de)情(qing)況下，還遵(zun)守“用(yong)(yong)盡、充滿”的(de)基本(ben)原則(ze)，那么電(dian)池(chi)的(de)壽(shou)命就(jiu)不長了。

誤區二：新買的鋰電池需要三次完全充放電才能將其充分激活，并且第一次充電要連續十個小時以上

當我(wo)們在(zai)(zai)(zai)購買led手電(dian)(dian)(dian)(dian)(dian)筒的(de)(de)時候，經(jing)銷店(dian)的(de)(de)營業員都(dou)會囑咐，回去使用(yong)時要給電(dian)(dian)(dian)(dian)(dian)池(chi)用(yong)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)充(chong)(chong)分(fen)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)和放電(dian)(dian)(dian)(dian)(dian)三次，這樣才能(neng)將鋰電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)分(fen)激活(huo)(huo)，保證以后鋰電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)使用(yong)效(xiao)能(neng)。在(zai)(zai)(zai)初次使用(yong)鋰電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)時候，出廠的(de)(de)鋰電(dian)(dian)(dian)(dian)(dian)池(chi)都(dou)帶(dai)有(you)(you)一定的(de)(de)電(dian)(dian)(dian)(dian)(dian)量，所以說(shuo)激活(huo)(huo)工(gong)作已經(jing)在(zai)(zai)(zai)工(gong)廠內(nei)就完成(cheng)了。其實在(zai)(zai)(zai)工(gong)藝上，鋰電(dian)(dian)(dian)(dian)(dian)池(chi)激活(huo)(huo)的(de)(de)過程必須(xu)在(zai)(zai)(zai)沒有(you)(you)“過充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)”保護(hu)電(dian)(dian)(dian)(dian)(dian)路存(cun)在(zai)(zai)(zai)的(de)(de)情(qing)況(kuang)下完成(cheng)。而現(xian)在(zai)(zai)(zai)使用(yong)的(de)(de)鋰電(dian)(dian)(dian)(dian)(dian)池(chi)內(nei)部(bu)都(dou)有(you)(you)自己(ji)的(de)(de)保護(hu)電(dian)(dian)(dian)(dian)(dian)路，而且充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)內(nei)部(bu)也有(you)(you)“過充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)”保護(hu)電(dian)(dian)(dian)(dian)(dian)路。所以說(shuo)按照(zhao)店(dian)家所介(jie)紹(shao)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)方法(fa)來激活(huo)(huo)鋰電(dian)(dian)(dian)(dian)(dian)池(chi)根本就無(wu)從談起(qi)。

所以，不必對電(dian)(dian)池(chi)進行十幾個小時(shi)的(de)充(chong)電(dian)(dian)來激活電(dian)(dian)池(chi)活性。但如(ru)果是由(you)于長時(shi)間的(de)擱置，鋰電(dian)(dian)池(chi)活性會有一(yi)定程度的(de)減(jian)少，所以在使用的(de)時(shi)候(hou)最好先將電(dian)(dian)池(chi)完全(quan)充(chong)電(dian)(dian)后(hou)再使用。

三、如何辨別強光手電筒鋰電池質量

Led強光(guang)手電(dian)筒(tong)一般都(dou)是采(cai)用(yong)18650鋰(li)電(dian)池已(yi)經成為了主流，而市(shi)場上(shang)的(de)防爆手電(dian)筒(tong)電(dian)池假的(de)占有多少，一般分為幾(ji)類

1、虛假容量：

目前中國18650電(dian)池(chi)技術就在2200容量，而(er)很多(duo)(duo)銷售(shou)商為了(le)吸引消費者，將底容量電(dian)池(chi)虛假的打上3000或者3200容量等，欺騙消費者，牟(mou)取更多(duo)(duo)的利益。

2、翻新電池：

翻(fan)新(xin)電池(chi)來源于國(guo)外(wai)拆機電池(chi)，通過一些非法渠道獲得，然后(hou)翻(fan)新(xin)，打上虛假容量，這累電池(chi)是(shi)非常危險，消費者是(shi)隨身帶上一棵定時(shi)爆炸物在(zai)身邊，還請(qing)消費者擦亮眼睛(jing)消費。

3、山寨電池：

山(shan)寨這兩個(ge)字相信大(da)家(jia)都(dou)熟悉(xi)不過的(de)(de)(de)，鋰(li)電(dian)(dian)池(chi)(chi)是一(yi)類由鋰(li)金(jin)屬或鋰(li)合金(jin)為負極材料、使(shi)(shi)用(yong)(yong)非(fei)水電(dian)(dian)解質(zhi)溶液的(de)(de)(de)電(dian)(dian)池(chi)(chi)，鋰(li)金(jin)屬的(de)(de)(de)化學特性非(fei)常活潑，使(shi)(shi)得鋰(li)金(jin)屬的(de)(de)(de)加工(gong)、保(bao)存(cun)、使(shi)(shi)用(yong)(yong)，對環境要求(qiu)非(fei)常高。山(shan)寨電(dian)(dian)池(chi)(chi)制(zhi)造者對這些要求(qiu)可能完全會(hui)忽(hu)略掉(diao)，弄不好(hao)隨(sui)時有危(wei)險(xian)的(de)(de)(de)可能。

消費者在購買LED手電筒的(de)同(tong)時(shi)，千萬要注意以上情況。到正規(gui)的(de)強(qiang)光手電筒廠家購買有(you)保障，最好選購品牌的(de)手電筒。
