一、強光手電筒一定要用匹配的鋰電池

用作強光手(shou)電(dian)筒(tong)光源的(de)鋰電(dian)池有較(jiao)多型(xing)號，常用的(de)有18650、17670、16340等，首(shou)先我們要認識這些型(xing)號表(biao)達的(de)意思，電(dian)池型(xing)號前面兩位數表(biao)示的(de)是電(dian)池直(zhi)徑(jing)，后面三位數表(biao)示高(gao)度。以(yi)市場應(ying)用最成(cheng)熟(shu)的(de)18650鋰電(dian)池來說(shuo)，其直(zhi)徑(jing)是18mm，高(gao)度是65mm；而(er)手(shou)電(dian)筒(tong)用的(de)16340電(dian)池則是指直(zhi)徑(jing)16mm，高(gao)度為34mm的(de)鋰電(dian)池。

既定電壓和放電電流的(de)手電筒燈(deng)泡(pao)要求鋰電池不(bu)能(neng)過流，更(geng)不(bu)能(neng)超壓。

對于(yu)0.85A的(de)(de)燈泡來說(shuo)，放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)最好是0.85A，如果(guo)電(dian)(dian)(dian)流(liu)過小，手電(dian)(dian)(dian)筒(tong)可(ke)能會(hui)(hui)亮(liang)度不夠，如果(guo)電(dian)(dian)(dian)流(liu)過大(da)(da)，又可(ke)能因過流(liu)而損壞電(dian)(dian)(dian)池結構，所以，“匹配(pei)”最好，既能獲得最大(da)(da)的(de)(de)亮(liang)度，也不會(hui)(hui)損害電(dian)(dian)(dian)池。比如，給0.85A的(de)(de)燈泡供電(dian)(dian)(dian)，友來16340鋰(li)電(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)流(liu)就(jiu)不行，可(ke)能會(hui)(hui)在亮(liang)過幾(ji)分鐘之后突然(ran)變暗，如果(guo)采用具有較大(da)(da)電(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)性能的(de)(de)雷鷹16340鋰(li)電(dian)(dian)(dian)池，放(fang)電(dian)(dian)(dian)效果(guo)就(jiu)會(hui)(hui)好許(xu)多(duo)。

7.2V燈泡應該使(shi)用(yong)兩只(zhi)鋰(li)電(dian)(dian)(dian)池(chi)串聯(lian)供電(dian)(dian)(dian)，因(yin)為鋰(li)電(dian)(dian)(dian)池(chi)的(de)額定電(dian)(dian)(dian)壓(ya)(ya)是3.6V~3.7V，兩只(zhi)3.6V電(dian)(dian)(dian)池(chi)串聯(lian)起來就是7.2V，另一方面，如果(guo)鋰(li)電(dian)(dian)(dian)池(chi)串聯(lian)起來的(de)電(dian)(dian)(dian)壓(ya)(ya)高于燈泡電(dian)(dian)(dian)壓(ya)(ya)過多(duo)的(de)話，這就是超壓(ya)(ya)運行(xing)，會導致燈泡被(bei)燒，所以，以前使(shi)用(yong)鎳氫電(dian)(dian)(dian)池(chi)的(de)手電(dian)(dian)(dian)筒，如果(guo)換成鋰(li)電(dian)(dian)(dian)池(chi)一定要換燈泡，超壓(ya)(ya)運行(xing)可以使(shi)手電(dian)(dian)(dian)筒量(liang)度更高，但(dan)負面的(de)作(zuo)用(yong)就是可能燒掉燈泡，得(de)不(bu)償失，因(yin)此選擇手電(dian)(dian)(dian)筒一定要用(yong)6V以上的(de)燈泡。

最后，就(jiu)是手電(dian)(dian)(dian)筒鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的充(chong)電(dian)(dian)(dian)，鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)器(qi)是根(gen)據(ju)電(dian)(dian)(dian)壓值判斷電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是否(fou)滿電(dian)(dian)(dian)的，單節鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)的終止(zhi)電(dian)(dian)(dian)壓是4.2V，你只要(yao)買的是正宗充(chong)電(dian)(dian)(dian)器(qi)，充(chong)電(dian)(dian)(dian)器(qi)就(jiu)會(hui)自動充(chong)到4.2V，然后停止(zhi)充(chong)電(dian)(dian)(dian)行為。這里強調指出(chu)，充(chong)電(dian)(dian)(dian)器(qi)的正宗很(hen)重要(yao)。

二、強光手電筒鋰電池使用誤區

該圖片由注冊用戶"異想天開"提供，版權聲明反饋

誤區一：鋰電池的“用盡、充滿”基本原則

不可(ke)否認，強光手電筒鋰(li)(li)電池(chi)也有(you)記(ji)憶(yi)效應(ying)(ying)，但其記(ji)憶(yi)效應(ying)(ying)是微乎其微的(de)(de)，連制造商對(dui)(dui)此記(ji)憶(yi)效應(ying)(ying)都(dou)忽略不記(ji)，因此，在一(yi)些對(dui)(dui)鋰(li)(li)電池(chi)產(chan)品的(de)(de)廣告中，可(ke)以看到廠商是打出“沒有(you)記(ji)憶(yi)效應(ying)(ying)，隨(sui)用(yong)隨(sui)充”的(de)(de)牌子。但在實際(ji)使(shi)(shi)(shi)用(yong)中，大家也許會(hui)發覺，鋰(li)(li)電池(chi)使(shi)(shi)(shi)用(yong)的(de)(de)時間會(hui)越來越短(duan)。這(zhe)是怎么回事呢？其實，鋰(li)(li)電池(chi)的(de)(de)制作(zuo)材料是一(yi)種活性(xing)(xing)物質(zhi)，活性(xing)(xing)物質(zhi)都(dou)會(hui)老化。而制作(zuo)鋰(li)(li)電池(chi)的(de)(de)材料，對(dui)(dui)于使(shi)(shi)(shi)用(yong)頻繁的(de)(de)程度和使(shi)(shi)(shi)用(yong)環境、溫度等等條件(jian)都(dou)比較(jiao)敏(min)感。

一(yi)般(ban)led手(shou)電(dian)(dian)(dian)(dian)筒鋰電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)使用壽命是(shi)充放電(dian)(dian)(dian)(dian)300～500次，電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)自然損耗會明顯(xian)縮短電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)持續使用時(shi)間。而對(dui)過(guo)度的(de)充電(dian)(dian)(dian)(dian)和過(guo)度的(de)放電(dian)(dian)(dian)(dian)，都會急(ji)速的(de)消減電(dian)(dian)(dian)(dian)池(chi)(chi)活(huo)性，直接導致鋰電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)快速老(lao)化。很多手(shou)機用戶可能(neng)都有(you)(you)這樣的(de)經歷，明明顯(xian)示(shi)還(huan)有(you)(you)一(yi)格電(dian)(dian)(dian)(dian)量，可半(ban)個小時(shi)后，就(jiu)會顯(xian)示(shi)“電(dian)(dian)(dian)(dian)量低”，有(you)(you)時(shi)候還(huan)會自動關機。

所以在平時使用時，我們(men)不(bu)(bu)必遵循“用盡、充滿”的基(ji)本原則。如果在檢(jian)測電(dian)路對(dui)電(dian)池檢(jian)測不(bu)(bu)準的情況下，還(huan)遵守“用盡、充滿”的基(ji)本原則，那(nei)么電(dian)池的壽(shou)命就不(bu)(bu)長(chang)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(dang)我們(men)在(zai)購買led手(shou)電(dian)(dian)(dian)筒的(de)時(shi)(shi)候，經銷店的(de)營業(ye)員都(dou)會囑(zhu)咐，回(hui)去使(shi)用(yong)(yong)(yong)時(shi)(shi)要給電(dian)(dian)(dian)池用(yong)(yong)(yong)充(chong)電(dian)(dian)(dian)器充(chong)分(fen)充(chong)電(dian)(dian)(dian)和放電(dian)(dian)(dian)三次，這樣(yang)才(cai)能將鋰(li)(li)電(dian)(dian)(dian)池充(chong)分(fen)激(ji)(ji)活，保(bao)(bao)證以后(hou)鋰(li)(li)電(dian)(dian)(dian)池的(de)使(shi)用(yong)(yong)(yong)效能。在(zai)初(chu)次使(shi)用(yong)(yong)(yong)鋰(li)(li)電(dian)(dian)(dian)池的(de)時(shi)(shi)候，出廠(chang)的(de)鋰(li)(li)電(dian)(dian)(dian)池都(dou)帶(dai)有一定(ding)的(de)電(dian)(dian)(dian)量，所(suo)以說(shuo)激(ji)(ji)活工作已經在(zai)工廠(chang)內(nei)就完(wan)成(cheng)了。其(qi)實在(zai)工藝上，鋰(li)(li)電(dian)(dian)(dian)池激(ji)(ji)活的(de)過程必須在(zai)沒有“過充(chong)電(dian)(dian)(dian)”保(bao)(bao)護電(dian)(dian)(dian)路(lu)存在(zai)的(de)情況下完(wan)成(cheng)。而(er)(er)現在(zai)使(shi)用(yong)(yong)(yong)的(de)鋰(li)(li)電(dian)(dian)(dian)池內(nei)部都(dou)有自己的(de)保(bao)(bao)護電(dian)(dian)(dian)路(lu)，而(er)(er)且充(chong)電(dian)(dian)(dian)器內(nei)部也有“過充(chong)電(dian)(dian)(dian)”保(bao)(bao)護電(dian)(dian)(dian)路(lu)。所(suo)以說(shuo)按照店家(jia)所(suo)介紹的(de)充(chong)電(dian)(dian)(dian)方法來激(ji)(ji)活鋰(li)(li)電(dian)(dian)(dian)池根本就無從(cong)談起。

所以，不必對電池進行十幾(ji)個小時(shi)的(de)(de)充電來激活(huo)(huo)電池活(huo)(huo)性(xing)(xing)。但如果是由于長時(shi)間的(de)(de)擱置，鋰電池活(huo)(huo)性(xing)(xing)會(hui)有一定(ding)程(cheng)度的(de)(de)減少，所以在使用的(de)(de)時(shi)候最(zui)好先將(jiang)電池完全充電后再使用。

三、如何辨別強光手電筒鋰電池質量

Led強光手(shou)(shou)電(dian)(dian)筒(tong)一般都是采用18650鋰電(dian)(dian)池已經成(cheng)為了(le)主流(liu)，而市場上的防爆手(shou)(shou)電(dian)(dian)筒(tong)電(dian)(dian)池假的占有多少，一般分為幾類

1、虛假容量：

目(mu)前中國18650電池技術就在2200容量(liang)，而(er)很多(duo)銷售商為(wei)了吸(xi)引消費(fei)(fei)者(zhe)，將底(di)容量(liang)電池虛(xu)假的打上3000或者(zhe)3200容量(liang)等，欺(qi)騙消費(fei)(fei)者(zhe)，牟(mou)取更多(duo)的利益。

2、翻新電池：

翻(fan)新(xin)電(dian)池來(lai)源于國外(wai)拆機電(dian)池，通過一些非(fei)法渠道獲得(de)，然后(hou)翻(fan)新(xin)，打(da)上虛假容量(liang)，這累電(dian)池是非(fei)常(chang)危險(xian)，消費者(zhe)(zhe)是隨身(shen)帶上一棵定時爆炸物在身(shen)邊(bian)，還請消費者(zhe)(zhe)擦亮眼睛消費。

3、山寨電池：

山寨這兩(liang)個字相信大家都熟悉不過的(de)(de)(de)，鋰(li)電(dian)池(chi)是一類由(you)鋰(li)金屬或(huo)鋰(li)合金為負極材料、使(shi)用非(fei)水電(dian)解質溶液的(de)(de)(de)電(dian)池(chi)，鋰(li)金屬的(de)(de)(de)化學(xue)特(te)性非(fei)常活潑(po)，使(shi)得鋰(li)金屬的(de)(de)(de)加工、保存、使(shi)用，對環境(jing)要(yao)求非(fei)常高。山寨電(dian)池(chi)制造者對這些要(yao)求可能完(wan)全會忽略掉，弄不好隨時有危險的(de)(de)(de)可能。

消費者在購買LED手電筒的同時，千萬要注(zhu)意以(yi)上情況(kuang)。到正規的強光手(shou)電筒廠家購買有保障(zhang)，最好選購品牌的手(shou)電筒。
