一、強光手電筒一定要用匹配的鋰電池

用(yong)作強光手電(dian)(dian)(dian)筒(tong)光源的(de)鋰電(dian)(dian)(dian)池(chi)有較多型(xing)號(hao)(hao)(hao)，常(chang)用(yong)的(de)有18650、17670、16340等，首先我們要認(ren)識這些型(xing)號(hao)(hao)(hao)表達(da)的(de)意思，電(dian)(dian)(dian)池(chi)型(xing)號(hao)(hao)(hao)前面兩位數(shu)表示的(de)是電(dian)(dian)(dian)池(chi)直徑，后面三位數(shu)表示高(gao)(gao)度。以市場應用(yong)最成熟的(de)18650鋰電(dian)(dian)(dian)池(chi)來說，其直徑是18mm，高(gao)(gao)度是65mm；而手電(dian)(dian)(dian)筒(tong)用(yong)的(de)16340電(dian)(dian)(dian)池(chi)則是指直徑16mm，高(gao)(gao)度為34mm的(de)鋰電(dian)(dian)(dian)池(chi)。

既(ji)定(ding)電(dian)壓和放(fang)電(dian)電(dian)流的手電(dian)筒燈泡要求鋰電(dian)池(chi)不(bu)能過流，更不(bu)能超壓。

對于0.85A的(de)燈(deng)(deng)泡來說，放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)最(zui)(zui)好是(shi)0.85A，如果(guo)電(dian)(dian)(dian)流(liu)(liu)過小，手電(dian)(dian)(dian)筒可能(neng)會亮(liang)度不夠，如果(guo)電(dian)(dian)(dian)流(liu)(liu)過大，又可能(neng)因過流(liu)(liu)而損壞電(dian)(dian)(dian)池結構，所以，“匹(pi)配”最(zui)(zui)好，既能(neng)獲得最(zui)(zui)大的(de)亮(liang)度，也不會損害電(dian)(dian)(dian)池。比如，給0.85A的(de)燈(deng)(deng)泡供電(dian)(dian)(dian)，友來16340鋰電(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)流(liu)(liu)就(jiu)不行，可能(neng)會在亮(liang)過幾分鐘之后(hou)突然變(bian)暗，如果(guo)采(cai)用(yong)具有(you)較大電(dian)(dian)(dian)流(liu)(liu)放電(dian)(dian)(dian)性能(neng)的(de)雷鷹16340鋰電(dian)(dian)(dian)池，放電(dian)(dian)(dian)效果(guo)就(jiu)會好許多。

7.2V燈泡(pao)應該使用(yong)兩(liang)只鋰(li)(li)電(dian)(dian)池(chi)串(chuan)聯(lian)供電(dian)(dian)，因(yin)為鋰(li)(li)電(dian)(dian)池(chi)的額定(ding)(ding)電(dian)(dian)壓是(shi)3.6V~3.7V，兩(liang)只3.6V電(dian)(dian)池(chi)串(chuan)聯(lian)起(qi)來就(jiu)是(shi)7.2V，另(ling)一(yi)方面，如果鋰(li)(li)電(dian)(dian)池(chi)串(chuan)聯(lian)起(qi)來的電(dian)(dian)壓高(gao)于燈泡(pao)電(dian)(dian)壓過多的話，這(zhe)就(jiu)是(shi)超壓運(yun)行，會導致燈泡(pao)被燒，所以(yi)(yi)，以(yi)(yi)前使用(yong)鎳氫(qing)電(dian)(dian)池(chi)的手電(dian)(dian)筒(tong)，如果換(huan)成鋰(li)(li)電(dian)(dian)池(chi)一(yi)定(ding)(ding)要換(huan)燈泡(pao)，超壓運(yun)行可以(yi)(yi)使手電(dian)(dian)筒(tong)量度更高(gao)，但(dan)負(fu)面的作用(yong)就(jiu)是(shi)可能燒掉(diao)燈泡(pao)，得不償失，因(yin)此選擇手電(dian)(dian)筒(tong)一(yi)定(ding)(ding)要用(yong)6V以(yi)(yi)上的燈泡(pao)。

最后(hou)，就是(shi)手電(dian)(dian)(dian)(dian)(dian)筒鋰電(dian)(dian)(dian)(dian)(dian)池的(de)充電(dian)(dian)(dian)(dian)(dian)，鋰電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)器(qi)是(shi)根據電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值判斷電(dian)(dian)(dian)(dian)(dian)池是(shi)否滿電(dian)(dian)(dian)(dian)(dian)的(de)，單節鋰電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)的(de)終(zhong)止電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)4.2V，你只要買的(de)是(shi)正宗充電(dian)(dian)(dian)(dian)(dian)器(qi)，充電(dian)(dian)(dian)(dian)(dian)器(qi)就會自(zi)動充到4.2V，然后(hou)停止充電(dian)(dian)(dian)(dian)(dian)行為。這(zhe)里強調(diao)指出(chu)，充電(dian)(dian)(dian)(dian)(dian)器(qi)的(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

不可否(fou)認，強光手電(dian)(dian)筒鋰(li)電(dian)(dian)池(chi)也有記(ji)(ji)憶(yi)效(xiao)(xiao)應(ying)(ying)，但其(qi)記(ji)(ji)憶(yi)效(xiao)(xiao)應(ying)(ying)是(shi)微(wei)乎其(qi)微(wei)的(de)(de)，連制(zhi)造(zao)商對(dui)此(ci)記(ji)(ji)憶(yi)效(xiao)(xiao)應(ying)(ying)都忽略不記(ji)(ji)，因此(ci)，在一(yi)些對(dui)鋰(li)電(dian)(dian)池(chi)產品的(de)(de)廣(guang)告中(zhong)，可以看到廠商是(shi)打出“沒有記(ji)(ji)憶(yi)效(xiao)(xiao)應(ying)(ying)，隨用(yong)隨充”的(de)(de)牌子。但在實(shi)際(ji)使(shi)用(yong)中(zhong)，大家也許會(hui)發覺(jue)，鋰(li)電(dian)(dian)池(chi)使(shi)用(yong)的(de)(de)時(shi)間會(hui)越(yue)來越(yue)短。這(zhe)是(shi)怎么回事呢？其(qi)實(shi)，鋰(li)電(dian)(dian)池(chi)的(de)(de)制(zhi)作材料是(shi)一(yi)種活(huo)性物質，活(huo)性物質都會(hui)老化。而(er)制(zhi)作鋰(li)電(dian)(dian)池(chi)的(de)(de)材料，對(dui)于使(shi)用(yong)頻繁的(de)(de)程(cheng)度(du)和(he)使(shi)用(yong)環境、溫度(du)等等條件都比較敏感。

一般led手電(dian)筒(tong)鋰(li)電(dian)池的使(shi)用壽命(ming)是充放電(dian)300～500次，電(dian)池的自然損耗會明顯縮短(duan)電(dian)池的持續(xu)使(shi)用時間。而對(dui)過(guo)度的充電(dian)和過(guo)度的放電(dian)，都(dou)會急(ji)速的消(xiao)減電(dian)池活(huo)性(xing)，直接導致鋰(li)電(dian)池的快(kuai)速老化。很多手機用戶(hu)可能都(dou)有(you)(you)這(zhe)樣的經歷，明明顯示還(huan)(huan)有(you)(you)一格電(dian)量(liang)，可半個(ge)小時后，就會顯示“電(dian)量(liang)低”，有(you)(you)時候還(huan)(huan)會自動關機。

所以在(zai)平(ping)時使用時，我們不必遵循“用盡(jin)、充滿(man)”的(de)基(ji)本(ben)原則。如果在(zai)檢測(ce)(ce)電路(lu)對(dui)電池檢測(ce)(ce)不準的(de)情況下，還遵守“用盡(jin)、充滿(man)”的(de)基(ji)本(ben)原則，那么電池的(de)壽命就不長了。

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

當我們在購買led手(shou)電(dian)(dian)(dian)(dian)筒的(de)(de)(de)(de)時(shi)候(hou)(hou)，經銷(xiao)店的(de)(de)(de)(de)營(ying)業員都(dou)會囑咐，回去使用(yong)(yong)時(shi)要給電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)用(yong)(yong)充(chong)電(dian)(dian)(dian)(dian)器充(chong)分充(chong)電(dian)(dian)(dian)(dian)和放電(dian)(dian)(dian)(dian)三次，這樣才能將(jiang)鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)分激(ji)(ji)活(huo)，保(bao)證以(yi)后鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)使用(yong)(yong)效能。在初次使用(yong)(yong)鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)時(shi)候(hou)(hou)，出廠(chang)的(de)(de)(de)(de)鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)都(dou)帶有一定的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)量，所以(yi)說激(ji)(ji)活(huo)工(gong)作已經在工(gong)廠(chang)內就完成了。其實在工(gong)藝上，鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)激(ji)(ji)活(huo)的(de)(de)(de)(de)過程必(bi)須在沒有“過充(chong)電(dian)(dian)(dian)(dian)”保(bao)護電(dian)(dian)(dian)(dian)路(lu)存在的(de)(de)(de)(de)情況下完成。而(er)現在使用(yong)(yong)的(de)(de)(de)(de)鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內部(bu)都(dou)有自(zi)己的(de)(de)(de)(de)保(bao)護電(dian)(dian)(dian)(dian)路(lu)，而(er)且(qie)充(chong)電(dian)(dian)(dian)(dian)器內部(bu)也有“過充(chong)電(dian)(dian)(dian)(dian)”保(bao)護電(dian)(dian)(dian)(dian)路(lu)。所以(yi)說按照(zhao)店家所介紹的(de)(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)方法(fa)來(lai)激(ji)(ji)活(huo)鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)根本就無從(cong)談起(qi)。

所(suo)(suo)以(yi)，不必對電(dian)池進行十(shi)幾個(ge)小(xiao)時(shi)的充電(dian)來(lai)激活電(dian)池活性(xing)。但如果(guo)是(shi)由于長時(shi)間(jian)的擱置，鋰電(dian)池活性(xing)會有(you)一(yi)定(ding)程度的減少，所(suo)(suo)以(yi)在使用的時(shi)候最好(hao)先(xian)將電(dian)池完(wan)全充電(dian)后(hou)再使用。

三、如何辨別強光手電筒鋰電池質量

Led強光手(shou)(shou)電筒一般都是采用18650鋰電池(chi)已經(jing)成為了主流，而市場上的防爆手(shou)(shou)電筒電池(chi)假的占有多(duo)少，一般分為幾類

1、虛假容量：

目(mu)前中國18650電池(chi)技術就在2200容量，而很多銷售(shou)商為(wei)了吸引消費者(zhe)，將底容量電池(chi)虛假的打上3000或者(zhe)3200容量等(deng)，欺騙消費者(zhe)，牟取更多的利(li)益(yi)。

2、翻新電池：

翻(fan)新電池(chi)來源于國外拆機電池(chi)，通過一(yi)些非法渠(qu)道獲得，然后翻(fan)新，打上(shang)虛(xu)假容(rong)量，這(zhe)累電池(chi)是(shi)非常危險，消(xiao)(xiao)費(fei)者是(shi)隨(sui)身(shen)帶上(shang)一(yi)棵定時(shi)爆炸物在(zai)身(shen)邊，還請消(xiao)(xiao)費(fei)者擦亮眼睛消(xiao)(xiao)費(fei)。

3、山寨電池：

山(shan)寨(zhai)這(zhe)兩個字相(xiang)信大家都熟(shu)悉不過的(de)，鋰(li)電池是一(yi)類由鋰(li)金屬或鋰(li)合(he)金為負極材料、使用非(fei)水電解質溶液(ye)的(de)電池，鋰(li)金屬的(de)化學特性非(fei)常活(huo)潑，使得鋰(li)金屬的(de)加工、保存、使用，對(dui)環境要(yao)求非(fei)常高。山(shan)寨(zhai)電池制造(zao)者對(dui)這(zhe)些要(yao)求可能完全會忽略掉，弄不好隨時有危險的(de)可能。

消費者在購買LED手電筒的同時，千(qian)萬要注意以上情況。到正規的強光手電(dian)筒廠家(jia)購買有保障，最(zui)好選(xuan)購品牌的手電(dian)筒。
