一、強光手電筒一定要用匹配的鋰電池

用(yong)作強光(guang)手(shou)電(dian)筒光(guang)源的(de)鋰電(dian)池有(you)較多型號(hao)，常用(yong)的(de)有(you)18650、17670、16340等(deng)，首先我們要認識這些型號(hao)表達的(de)意思，電(dian)池型號(hao)前面兩位數表示的(de)是電(dian)池直徑，后面三位數表示高度(du)。以(yi)市(shi)場應用(yong)最成熟的(de)18650鋰電(dian)池來說(shuo)，其直徑是18mm，高度(du)是65mm；而手(shou)電(dian)筒用(yong)的(de)16340電(dian)池則(ze)是指直徑16mm，高度(du)為34mm的(de)鋰電(dian)池。

既(ji)定電(dian)(dian)壓(ya)(ya)和(he)放(fang)電(dian)(dian)電(dian)(dian)流(liu)的(de)手電(dian)(dian)筒燈泡(pao)要求(qiu)鋰(li)電(dian)(dian)池不能(neng)過流(liu)，更(geng)不能(neng)超壓(ya)(ya)。

對于0.85A的(de)燈(deng)泡來(lai)說，放電(dian)(dian)電(dian)(dian)流最(zui)好(hao)是0.85A，如果電(dian)(dian)流過(guo)小，手電(dian)(dian)筒可能(neng)會(hui)亮度不(bu)夠(gou)，如果電(dian)(dian)流過(guo)大(da)，又可能(neng)因過(guo)流而損壞(huai)電(dian)(dian)池(chi)(chi)(chi)結構，所以，“匹配”最(zui)好(hao)，既能(neng)獲得(de)最(zui)大(da)的(de)亮度，也不(bu)會(hui)損害電(dian)(dian)池(chi)(chi)(chi)。比如，給0.85A的(de)燈(deng)泡供電(dian)(dian)，友來(lai)16340鋰電(dian)(dian)池(chi)(chi)(chi)的(de)電(dian)(dian)流就(jiu)不(bu)行，可能(neng)會(hui)在亮過(guo)幾分鐘(zhong)之后突然變暗，如果采用具(ju)有較大(da)電(dian)(dian)流放電(dian)(dian)性能(neng)的(de)雷鷹16340鋰電(dian)(dian)池(chi)(chi)(chi)，放電(dian)(dian)效果就(jiu)會(hui)好(hao)許多。

7.2V燈(deng)泡(pao)(pao)應該使用兩只鋰(li)電(dian)池串(chuan)聯供電(dian)，因為(wei)鋰(li)電(dian)池的(de)額定(ding)電(dian)壓(ya)是(shi)(shi)3.6V~3.7V，兩只3.6V電(dian)池串(chuan)聯起來就是(shi)(shi)7.2V，另一方(fang)面，如果鋰(li)電(dian)池串(chuan)聯起來的(de)電(dian)壓(ya)高于燈(deng)泡(pao)(pao)電(dian)壓(ya)過多的(de)話，這(zhe)就是(shi)(shi)超壓(ya)運行(xing)，會導致燈(deng)泡(pao)(pao)被燒(shao)，所(suo)以，以前使用鎳氫電(dian)池的(de)手(shou)電(dian)筒(tong)，如果換(huan)成(cheng)鋰(li)電(dian)池一定(ding)要換(huan)燈(deng)泡(pao)(pao)，超壓(ya)運行(xing)可(ke)以使手(shou)電(dian)筒(tong)量度(du)更高，但負面的(de)作用就是(shi)(shi)可(ke)能(neng)燒(shao)掉燈(deng)泡(pao)(pao)，得不償失，因此選擇手(shou)電(dian)筒(tong)一定(ding)要用6V以上的(de)燈(deng)泡(pao)(pao)。

最后(hou)，就是手(shou)電(dian)(dian)(dian)(dian)(dian)筒鋰電(dian)(dian)(dian)(dian)(dian)池的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，鋰電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器是根據電(dian)(dian)(dian)(dian)(dian)壓值判斷電(dian)(dian)(dian)(dian)(dian)池是否滿電(dian)(dian)(dian)(dian)(dian)的，單節鋰電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的終止(zhi)電(dian)(dian)(dian)(dian)(dian)壓是4.2V，你只要買的是正宗(zong)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器就會自動充(chong)(chong)(chong)到4.2V，然后(hou)停(ting)止(zhi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)行為。這里強調指出，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器的正宗(zong)很(hen)重要。

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

不可否認(ren)，強光手電(dian)(dian)筒(tong)鋰電(dian)(dian)池也有記憶(yi)(yi)效(xiao)(xiao)應，但(dan)其(qi)記憶(yi)(yi)效(xiao)(xiao)應是(shi)微(wei)乎其(qi)微(wei)的(de)(de)(de)，連制造商對此(ci)記憶(yi)(yi)效(xiao)(xiao)應都(dou)(dou)忽略不記，因此(ci)，在(zai)一些對鋰電(dian)(dian)池產品的(de)(de)(de)廣告中，可以看(kan)到廠商是(shi)打出“沒有記憶(yi)(yi)效(xiao)(xiao)應，隨用(yong)(yong)隨充”的(de)(de)(de)牌子(zi)。但(dan)在(zai)實(shi)際(ji)使(shi)(shi)用(yong)(yong)中，大家也許會(hui)發覺，鋰電(dian)(dian)池使(shi)(shi)用(yong)(yong)的(de)(de)(de)時間會(hui)越(yue)來越(yue)短(duan)。這是(shi)怎(zen)么(me)回事呢？其(qi)實(shi)，鋰電(dian)(dian)池的(de)(de)(de)制作(zuo)材料是(shi)一種活(huo)性(xing)物(wu)質，活(huo)性(xing)物(wu)質都(dou)(dou)會(hui)老(lao)化。而(er)制作(zuo)鋰電(dian)(dian)池的(de)(de)(de)材料，對于(yu)使(shi)(shi)用(yong)(yong)頻繁的(de)(de)(de)程度和使(shi)(shi)用(yong)(yong)環境、溫度等(deng)等(deng)條(tiao)件都(dou)(dou)比較敏感。

一般led手(shou)電(dian)(dian)(dian)筒鋰(li)電(dian)(dian)(dian)池(chi)的(de)(de)使用(yong)壽命是充放電(dian)(dian)(dian)300～500次，電(dian)(dian)(dian)池(chi)的(de)(de)自然損耗會(hui)明顯縮短電(dian)(dian)(dian)池(chi)的(de)(de)持續(xu)使用(yong)時(shi)間。而對過度的(de)(de)充電(dian)(dian)(dian)和(he)過度的(de)(de)放電(dian)(dian)(dian)，都(dou)(dou)會(hui)急速(su)的(de)(de)消減電(dian)(dian)(dian)池(chi)活性，直接導致鋰(li)電(dian)(dian)(dian)池(chi)的(de)(de)快速(su)老化。很多手(shou)機(ji)用(yong)戶可(ke)能(neng)都(dou)(dou)有(you)這(zhe)樣(yang)的(de)(de)經歷，明明顯示還有(you)一格電(dian)(dian)(dian)量，可(ke)半個小時(shi)后，就(jiu)會(hui)顯示“電(dian)(dian)(dian)量低”，有(you)時(shi)候(hou)還會(hui)自動關機(ji)。

所以在平(ping)時使用時，我們不(bu)必遵(zun)循(xun)“用盡、充滿(man)”的(de)基本(ben)原則。如果(guo)在檢測(ce)電(dian)路對電(dian)池檢測(ce)不(bu)準的(de)情況下，還遵(zun)守“用盡、充滿(man)”的(de)基本(ben)原則，那么電(dian)池的(de)壽命(ming)就不(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)購(gou)買led手電(dian)(dian)(dian)(dian)筒(tong)的(de)(de)時候，經(jing)銷(xiao)店的(de)(de)營業員(yuan)都會囑咐，回去使(shi)(shi)用時要給電(dian)(dian)(dian)(dian)池用充(chong)(chong)電(dian)(dian)(dian)(dian)器充(chong)(chong)分(fen)(fen)充(chong)(chong)電(dian)(dian)(dian)(dian)和放電(dian)(dian)(dian)(dian)三(san)次(ci)，這樣才能(neng)將鋰(li)電(dian)(dian)(dian)(dian)池充(chong)(chong)分(fen)(fen)激活(huo)(huo)，保(bao)(bao)證(zheng)以后鋰(li)電(dian)(dian)(dian)(dian)池的(de)(de)使(shi)(shi)用效(xiao)能(neng)。在(zai)(zai)初次(ci)使(shi)(shi)用鋰(li)電(dian)(dian)(dian)(dian)池的(de)(de)時候，出(chu)廠的(de)(de)鋰(li)電(dian)(dian)(dian)(dian)池都帶有一定的(de)(de)電(dian)(dian)(dian)(dian)量，所以說(shuo)激活(huo)(huo)工作已經(jing)在(zai)(zai)工廠內就完成了。其實在(zai)(zai)工藝上(shang)，鋰(li)電(dian)(dian)(dian)(dian)池激活(huo)(huo)的(de)(de)過程必(bi)須在(zai)(zai)沒(mei)有“過充(chong)(chong)電(dian)(dian)(dian)(dian)”保(bao)(bao)護(hu)電(dian)(dian)(dian)(dian)路存在(zai)(zai)的(de)(de)情況下完成。而(er)現在(zai)(zai)使(shi)(shi)用的(de)(de)鋰(li)電(dian)(dian)(dian)(dian)池內部都有自己(ji)的(de)(de)保(bao)(bao)護(hu)電(dian)(dian)(dian)(dian)路，而(er)且(qie)充(chong)(chong)電(dian)(dian)(dian)(dian)器內部也有“過充(chong)(chong)電(dian)(dian)(dian)(dian)”保(bao)(bao)護(hu)電(dian)(dian)(dian)(dian)路。所以說(shuo)按(an)照店家所介紹的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)方(fang)法來(lai)激活(huo)(huo)鋰(li)電(dian)(dian)(dian)(dian)池根本就無從談起。

所以，不(bu)必對(dui)電池(chi)進行(xing)十幾(ji)個小時(shi)(shi)的(de)(de)充(chong)電來激活電池(chi)活性。但如果(guo)是由于長時(shi)(shi)間的(de)(de)擱置，鋰電池(chi)活性會有(you)一定程度的(de)(de)減少，所以在使用的(de)(de)時(shi)(shi)候最好先將電池(chi)完(wan)全(quan)充(chong)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)電筒(tong)一(yi)般都是采用18650鋰電池(chi)(chi)已經(jing)成為了主(zhu)流，而市場上(shang)的防爆手(shou)電筒(tong)電池(chi)(chi)假的占有多少，一(yi)般分(fen)為幾類

1、虛假容量：

目前中國18650電(dian)池(chi)技術就在(zai)2200容(rong)(rong)量，而(er)很多銷售商(shang)為(wei)了(le)吸引消費者(zhe)，將底(di)容(rong)(rong)量電(dian)池(chi)虛假(jia)的打上3000或者(zhe)3200容(rong)(rong)量等，欺騙(pian)消費者(zhe)，牟取更(geng)多的利益(yi)。

2、翻新電池：

翻新電池來源于國外拆機電池，通過一些非(fei)法(fa)渠道獲得，然后翻新，打上(shang)(shang)虛假(jia)容量，這累電池是非(fei)常危險，消費(fei)(fei)者是隨(sui)身(shen)帶上(shang)(shang)一棵(ke)定時(shi)爆炸物在身(shen)邊，還(huan)請消費(fei)(fei)者擦亮眼睛消費(fei)(fei)。

3、山寨電池：

山(shan)寨(zhai)這(zhe)兩個字相信大家都熟悉(xi)不過的(de)，鋰(li)電(dian)池是一(yi)類由鋰(li)金屬或鋰(li)合金為負極材(cai)料(liao)、使(shi)用非水電(dian)解質溶(rong)液的(de)電(dian)池，鋰(li)金屬的(de)化學特性非常活(huo)潑，使(shi)得鋰(li)金屬的(de)加工、保存、使(shi)用，對環境要求(qiu)非常高。山(shan)寨(zhai)電(dian)池制造者對這(zhe)些要求(qiu)可能完全會忽略(lve)掉，弄不好隨時有(you)危險的(de)可能。

消費者在購買LED手電筒的(de)同時，千萬要注意以上(shang)情況。到正(zheng)規的(de)強光手(shou)(shou)電(dian)筒廠(chang)家(jia)購買有(you)保障，最好選購品牌的(de)手(shou)(shou)電(dian)筒。
