一、強光手電筒一定要用匹配的鋰電池

用(yong)(yong)作(zuo)強光手電(dian)(dian)筒光源的(de)(de)(de)鋰(li)電(dian)(dian)池有較多型(xing)(xing)號，常用(yong)(yong)的(de)(de)(de)有18650、17670、16340等(deng)，首先我們要(yao)認識這些型(xing)(xing)號表達的(de)(de)(de)意思(si)，電(dian)(dian)池型(xing)(xing)號前面兩位數表示的(de)(de)(de)是電(dian)(dian)池直(zhi)(zhi)徑(jing)，后面三位數表示高(gao)度。以市場應用(yong)(yong)最成熟的(de)(de)(de)18650鋰(li)電(dian)(dian)池來說，其直(zhi)(zhi)徑(jing)是18mm，高(gao)度是65mm；而手電(dian)(dian)筒用(yong)(yong)的(de)(de)(de)16340電(dian)(dian)池則是指直(zhi)(zhi)徑(jing)16mm，高(gao)度為34mm的(de)(de)(de)鋰(li)電(dian)(dian)池。

既定電(dian)(dian)壓和放電(dian)(dian)電(dian)(dian)流的手電(dian)(dian)筒燈泡要求鋰電(dian)(dian)池不(bu)能過流，更不(bu)能超壓。

對于(yu)0.85A的(de)燈泡來(lai)說，放電(dian)(dian)電(dian)(dian)流(liu)(liu)最(zui)好是(shi)0.85A，如(ru)(ru)(ru)果電(dian)(dian)流(liu)(liu)過(guo)(guo)小，手電(dian)(dian)筒(tong)可(ke)能(neng)會(hui)(hui)亮(liang)度不夠，如(ru)(ru)(ru)果電(dian)(dian)流(liu)(liu)過(guo)(guo)大，又可(ke)能(neng)因過(guo)(guo)流(liu)(liu)而損壞電(dian)(dian)池結(jie)構，所(suo)以(yi)，“匹(pi)配”最(zui)好，既(ji)能(neng)獲得最(zui)大的(de)亮(liang)度，也不會(hui)(hui)損害電(dian)(dian)池。比(bi)如(ru)(ru)(ru)，給0.85A的(de)燈泡供電(dian)(dian)，友來(lai)16340鋰(li)電(dian)(dian)池的(de)電(dian)(dian)流(liu)(liu)就(jiu)不行，可(ke)能(neng)會(hui)(hui)在亮(liang)過(guo)(guo)幾分鐘之后突(tu)然變暗，如(ru)(ru)(ru)果采用具有(you)較大電(dian)(dian)流(liu)(liu)放電(dian)(dian)性能(neng)的(de)雷鷹16340鋰(li)電(dian)(dian)池，放電(dian)(dian)效果就(jiu)會(hui)(hui)好許多。

7.2V燈(deng)(deng)(deng)泡應該使用兩只鋰(li)(li)電(dian)池(chi)(chi)(chi)串聯(lian)供電(dian)，因為鋰(li)(li)電(dian)池(chi)(chi)(chi)的(de)(de)(de)額定(ding)電(dian)壓(ya)(ya)是3.6V~3.7V，兩只3.6V電(dian)池(chi)(chi)(chi)串聯(lian)起來(lai)就是7.2V，另(ling)一方面，如果(guo)(guo)鋰(li)(li)電(dian)池(chi)(chi)(chi)串聯(lian)起來(lai)的(de)(de)(de)電(dian)壓(ya)(ya)高(gao)于燈(deng)(deng)(deng)泡電(dian)壓(ya)(ya)過多(duo)的(de)(de)(de)話，這就是超(chao)壓(ya)(ya)運(yun)行(xing)，會(hui)導致燈(deng)(deng)(deng)泡被燒(shao)，所以，以前使用鎳氫電(dian)池(chi)(chi)(chi)的(de)(de)(de)手電(dian)筒，如果(guo)(guo)換成鋰(li)(li)電(dian)池(chi)(chi)(chi)一定(ding)要換燈(deng)(deng)(deng)泡，超(chao)壓(ya)(ya)運(yun)行(xing)可以使手電(dian)筒量(liang)度更高(gao)，但負(fu)面的(de)(de)(de)作用就是可能燒(shao)掉燈(deng)(deng)(deng)泡，得不(bu)償失(shi)，因此選擇手電(dian)筒一定(ding)要用6V以上(shang)的(de)(de)(de)燈(deng)(deng)(deng)泡。

最后，就是手電(dian)(dian)(dian)筒鋰電(dian)(dian)(dian)池的(de)(de)充(chong)(chong)電(dian)(dian)(dian)，鋰電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)是根(gen)據電(dian)(dian)(dian)壓(ya)值(zhi)判斷(duan)電(dian)(dian)(dian)池是否滿電(dian)(dian)(dian)的(de)(de)，單節(jie)鋰電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)的(de)(de)終止電(dian)(dian)(dian)壓(ya)是4.2V，你只要(yao)買的(de)(de)是正宗充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)，充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)就會自(zi)動充(chong)(chong)到4.2V，然(ran)后停止充(chong)(chong)電(dian)(dian)(dian)行為。這里強調指(zhi)出，充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)的(de)(de)正宗很重要(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(bu)可(ke)否認(ren)，強光手電(dian)筒(tong)鋰(li)(li)電(dian)池(chi)也有記憶(yi)效(xiao)應(ying)(ying)，但其(qi)(qi)記憶(yi)效(xiao)應(ying)(ying)是(shi)(shi)微乎其(qi)(qi)微的(de)，連制造商(shang)對(dui)此記憶(yi)效(xiao)應(ying)(ying)都(dou)忽略不(bu)記，因此，在(zai)一些對(dui)鋰(li)(li)電(dian)池(chi)產品的(de)廣(guang)告(gao)中，可(ke)以(yi)看到廠商(shang)是(shi)(shi)打(da)出“沒有記憶(yi)效(xiao)應(ying)(ying)，隨用隨充”的(de)牌子。但在(zai)實際使(shi)(shi)用中，大(da)家也許會發覺，鋰(li)(li)電(dian)池(chi)使(shi)(shi)用的(de)時間會越來越短。這(zhe)是(shi)(shi)怎么回事呢？其(qi)(qi)實，鋰(li)(li)電(dian)池(chi)的(de)制作材(cai)料(liao)是(shi)(shi)一種活(huo)性物(wu)質，活(huo)性物(wu)質都(dou)會老(lao)化。而(er)制作鋰(li)(li)電(dian)池(chi)的(de)材(cai)料(liao)，對(dui)于使(shi)(shi)用頻繁的(de)程(cheng)度(du)和使(shi)(shi)用環境、溫度(du)等等條件(jian)都(dou)比(bi)較敏(min)感。

一般led手電(dian)(dian)筒鋰電(dian)(dian)池(chi)的(de)(de)(de)(de)使用(yong)壽(shou)命是充放(fang)電(dian)(dian)300～500次，電(dian)(dian)池(chi)的(de)(de)(de)(de)自然損耗會(hui)明顯(xian)縮(suo)短電(dian)(dian)池(chi)的(de)(de)(de)(de)持(chi)續使用(yong)時(shi)間。而對過(guo)度的(de)(de)(de)(de)充電(dian)(dian)和過(guo)度的(de)(de)(de)(de)放(fang)電(dian)(dian)，都會(hui)急(ji)速(su)的(de)(de)(de)(de)消減電(dian)(dian)池(chi)活性，直接導致鋰電(dian)(dian)池(chi)的(de)(de)(de)(de)快速(su)老化。很多手機(ji)用(yong)戶可(ke)能都有這樣(yang)的(de)(de)(de)(de)經歷，明明顯(xian)示還(huan)有一格電(dian)(dian)量(liang)，可(ke)半個小時(shi)后，就會(hui)顯(xian)示“電(dian)(dian)量(liang)低”，有時(shi)候(hou)還(huan)會(hui)自動(dong)關機(ji)。

所以在平時使(shi)用(yong)時，我們不(bu)必遵(zun)循“用(yong)盡、充(chong)滿(man)”的基(ji)本原(yuan)則。如果在檢測電(dian)路對電(dian)池(chi)檢測不(bu)準的情況(kuang)下，還遵(zun)守“用(yong)盡、充(chong)滿(man)”的基(ji)本原(yuan)則，那么電(dian)池(chi)的壽命就(jiu)不(bu)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(zai)(zai)(zai)(zai)(zai)購買led手電(dian)(dian)(dian)(dian)筒的(de)(de)(de)(de)(de)(de)時候，經(jing)銷店(dian)的(de)(de)(de)(de)(de)(de)營業員都會(hui)囑(zhu)咐，回去使用(yong)時要給電(dian)(dian)(dian)(dian)池用(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(yang)才(cai)能將鋰(li)電(dian)(dian)(dian)(dian)池充(chong)分激(ji)活(huo)，保證以后鋰(li)電(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)(de)(de)使用(yong)效能。在(zai)(zai)(zai)(zai)(zai)初次使用(yong)鋰(li)電(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)(de)(de)時候，出廠(chang)的(de)(de)(de)(de)(de)(de)鋰(li)電(dian)(dian)(dian)(dian)池都帶有(you)一(yi)定的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)量，所以說(shuo)激(ji)活(huo)工作已經(jing)在(zai)(zai)(zai)(zai)(zai)工廠(chang)內(nei)就完成(cheng)了。其實(shi)在(zai)(zai)(zai)(zai)(zai)工藝上，鋰(li)電(dian)(dian)(dian)(dian)池激(ji)活(huo)的(de)(de)(de)(de)(de)(de)過(guo)程必須在(zai)(zai)(zai)(zai)(zai)沒有(you)“過(guo)充(chong)電(dian)(dian)(dian)(dian)”保護電(dian)(dian)(dian)(dian)路存在(zai)(zai)(zai)(zai)(zai)的(de)(de)(de)(de)(de)(de)情況下完成(cheng)。而(er)現(xian)在(zai)(zai)(zai)(zai)(zai)使用(yong)的(de)(de)(de)(de)(de)(de)鋰(li)電(dian)(dian)(dian)(dian)池內(nei)部(bu)都有(you)自己的(de)(de)(de)(de)(de)(de)保護電(dian)(dian)(dian)(dian)路，而(er)且充(chong)電(dian)(dian)(dian)(dian)器內(nei)部(bu)也有(you)“過(guo)充(chong)電(dian)(dian)(dian)(dian)”保護電(dian)(dian)(dian)(dian)路。所以說(shuo)按照店(dian)家所介紹的(de)(de)(de)(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)方法(fa)來激(ji)活(huo)鋰(li)電(dian)(dian)(dian)(dian)池根本就無(wu)從談起。

所以(yi)，不必對電池(chi)(chi)進行(xing)十幾個小時(shi)的充電來激活電池(chi)(chi)活性。但(dan)如果是由(you)于長時(shi)間的擱置，鋰電池(chi)(chi)活性會有一(yi)定程(cheng)度(du)的減少，所以(yi)在使用的時(shi)候最好先將電池(chi)(chi)完全充電后再使用。

三、如何辨別強光手電筒鋰電池質量

Led強光手電(dian)筒一般(ban)都(dou)是(shi)采用(yong)18650鋰(li)電(dian)池(chi)已經成為了主流，而(er)市場(chang)上的(de)防爆手電(dian)筒電(dian)池(chi)假的(de)占有多(duo)少(shao)，一般(ban)分為幾類

1、虛假容量：

目前中國(guo)18650電池(chi)技術就在2200容量(liang)(liang)，而很多(duo)銷售商為(wei)了吸(xi)引消費(fei)者，將底容量(liang)(liang)電池(chi)虛假(jia)的打上3000或者3200容量(liang)(liang)等，欺騙消費(fei)者，牟取更多(duo)的利益。

2、翻新電池：

翻新電池來(lai)源(yuan)于國(guo)外(wai)拆機電池，通過一些非(fei)法(fa)渠(qu)道獲得，然后翻新，打上(shang)虛假容量，這累電池是(shi)非(fei)常危(wei)險，消(xiao)費者是(shi)隨(sui)身帶上(shang)一棵(ke)定時爆炸物(wu)在身邊，還請(qing)消(xiao)費者擦亮眼(yan)睛消(xiao)費。

3、山寨電池：

山寨這兩個(ge)字相信大家都熟悉不過的(de)(de)，鋰(li)(li)(li)電池是一(yi)類由鋰(li)(li)(li)金(jin)(jin)(jin)屬(shu)或鋰(li)(li)(li)合金(jin)(jin)(jin)為(wei)負(fu)極材料、使(shi)用(yong)非(fei)水電解質溶液的(de)(de)電池，鋰(li)(li)(li)金(jin)(jin)(jin)屬(shu)的(de)(de)化學(xue)特性非(fei)常活潑，使(shi)得鋰(li)(li)(li)金(jin)(jin)(jin)屬(shu)的(de)(de)加工、保存、使(shi)用(yong)，對(dui)環境要求非(fei)常高。山寨電池制造者(zhe)對(dui)這些要求可(ke)能(neng)(neng)完(wan)全會忽略掉(diao)，弄不好隨時有危險的(de)(de)可(ke)能(neng)(neng)。

消費者在購買LED手電筒的(de)同時，千(qian)萬要注意以上(shang)情況。到正規的(de)強(qiang)光手(shou)電(dian)筒(tong)廠家購(gou)買有保(bao)障，最好選購(gou)品牌(pai)的(de)手(shou)電(dian)筒(tong)。
