一、強光手電筒一定要用匹配的鋰電池

用作強光手電(dian)筒光源的(de)鋰電(dian)池(chi)有(you)較多(duo)型(xing)號，常用的(de)有(you)18650、17670、16340等，首先我們要認識這些型(xing)號表達的(de)意思，電(dian)池(chi)型(xing)號前面兩(liang)位(wei)數(shu)表示的(de)是(shi)(shi)電(dian)池(chi)直(zhi)徑，后面三(san)位(wei)數(shu)表示高(gao)度。以市(shi)場應用最成熟的(de)18650鋰電(dian)池(chi)來說，其直(zhi)徑是(shi)(shi)18mm，高(gao)度是(shi)(shi)65mm；而手電(dian)筒用的(de)16340電(dian)池(chi)則是(shi)(shi)指直(zhi)徑16mm，高(gao)度為34mm的(de)鋰電(dian)池(chi)。

既定電(dian)壓(ya)和放電(dian)電(dian)流(liu)(liu)的手電(dian)筒燈泡要求鋰(li)電(dian)池不能過流(liu)(liu)，更(geng)不能超壓(ya)。

對(dui)于0.85A的(de)燈泡來說，放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)最好(hao)是0.85A，如果電(dian)(dian)(dian)流(liu)過(guo)小，手(shou)電(dian)(dian)(dian)筒(tong)可能(neng)(neng)會亮度(du)不夠(gou)，如果電(dian)(dian)(dian)流(liu)過(guo)大，又可能(neng)(neng)因過(guo)流(liu)而損壞電(dian)(dian)(dian)池(chi)(chi)結構，所以，“匹配”最好(hao)，既能(neng)(neng)獲得(de)最大的(de)亮度(du)，也不會損害電(dian)(dian)(dian)池(chi)(chi)。比(bi)如，給0.85A的(de)燈泡供電(dian)(dian)(dian)，友來16340鋰電(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)流(liu)就(jiu)(jiu)不行(xing)，可能(neng)(neng)會在亮過(guo)幾分鐘之后突然變(bian)暗，如果采用(yong)具(ju)有(you)較(jiao)大電(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)性能(neng)(neng)的(de)雷鷹16340鋰電(dian)(dian)(dian)池(chi)(chi)，放(fang)電(dian)(dian)(dian)效果就(jiu)(jiu)會好(hao)許多。

7.2V燈(deng)泡(pao)應該使(shi)用兩只鋰電(dian)(dian)池(chi)串聯(lian)供電(dian)(dian)，因為鋰電(dian)(dian)池(chi)的(de)(de)額定(ding)電(dian)(dian)壓是(shi)3.6V~3.7V，兩只3.6V電(dian)(dian)池(chi)串聯(lian)起來就(jiu)(jiu)是(shi)7.2V，另一(yi)方面(mian)，如(ru)果(guo)(guo)鋰電(dian)(dian)池(chi)串聯(lian)起來的(de)(de)電(dian)(dian)壓高于燈(deng)泡(pao)電(dian)(dian)壓過多的(de)(de)話，這就(jiu)(jiu)是(shi)超壓運(yun)行(xing)，會導致(zhi)燈(deng)泡(pao)被燒，所以，以前使(shi)用鎳氫電(dian)(dian)池(chi)的(de)(de)手電(dian)(dian)筒，如(ru)果(guo)(guo)換成鋰電(dian)(dian)池(chi)一(yi)定(ding)要換燈(deng)泡(pao)，超壓運(yun)行(xing)可(ke)(ke)以使(shi)手電(dian)(dian)筒量度更高，但負面(mian)的(de)(de)作用就(jiu)(jiu)是(shi)可(ke)(ke)能(neng)燒掉燈(deng)泡(pao)，得不償失(shi)，因此選擇手電(dian)(dian)筒一(yi)定(ding)要用6V以上的(de)(de)燈(deng)泡(pao)。

最后，就是(shi)(shi)手電(dian)(dian)(dian)(dian)(dian)筒鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的充(chong)電(dian)(dian)(dian)(dian)(dian)，鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)(shi)根據(ju)電(dian)(dian)(dian)(dian)(dian)壓值判斷電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)(shi)否滿電(dian)(dian)(dian)(dian)(dian)的，單節鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)的終止電(dian)(dian)(dian)(dian)(dian)壓是(shi)(shi)4.2V，你只要(yao)買的是(shi)(shi)正(zheng)宗(zong)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)就會自動充(chong)到4.2V，然后停止充(chong)電(dian)(dian)(dian)(dian)(dian)行為。這里強調指出，充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的正(zheng)宗(zong)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

不可(ke)(ke)否認，強光手電(dian)筒(tong)鋰電(dian)池也有記(ji)(ji)(ji)憶(yi)效(xiao)應(ying)，但其(qi)(qi)記(ji)(ji)(ji)憶(yi)效(xiao)應(ying)是(shi)(shi)微(wei)乎其(qi)(qi)微(wei)的(de)(de)，連制造(zao)商(shang)對(dui)(dui)此記(ji)(ji)(ji)憶(yi)效(xiao)應(ying)都(dou)忽略不記(ji)(ji)(ji)，因此，在一(yi)些對(dui)(dui)鋰電(dian)池產品(pin)的(de)(de)廣(guang)告中，可(ke)(ke)以看到廠商(shang)是(shi)(shi)打出“沒有記(ji)(ji)(ji)憶(yi)效(xiao)應(ying)，隨(sui)用(yong)(yong)隨(sui)充”的(de)(de)牌子。但在實(shi)際使(shi)(shi)用(yong)(yong)中，大(da)家也許會(hui)發覺，鋰電(dian)池使(shi)(shi)用(yong)(yong)的(de)(de)時(shi)間會(hui)越來(lai)越短。這是(shi)(shi)怎(zen)么回事呢？其(qi)(qi)實(shi)，鋰電(dian)池的(de)(de)制作(zuo)材(cai)料是(shi)(shi)一(yi)種活性物(wu)質(zhi)(zhi)，活性物(wu)質(zhi)(zhi)都(dou)會(hui)老化。而制作(zuo)鋰電(dian)池的(de)(de)材(cai)料，對(dui)(dui)于使(shi)(shi)用(yong)(yong)頻繁的(de)(de)程度和使(shi)(shi)用(yong)(yong)環境、溫度等等條件(jian)都(dou)比較敏(min)感。

一般led手電(dian)(dian)(dian)(dian)筒鋰電(dian)(dian)(dian)(dian)池的(de)(de)使用(yong)壽命(ming)是充放電(dian)(dian)(dian)(dian)300～500次，電(dian)(dian)(dian)(dian)池的(de)(de)自(zi)然損耗會(hui)明顯縮短(duan)電(dian)(dian)(dian)(dian)池的(de)(de)持續使用(yong)時(shi)間。而對過(guo)度的(de)(de)充電(dian)(dian)(dian)(dian)和過(guo)度的(de)(de)放電(dian)(dian)(dian)(dian)，都會(hui)急速的(de)(de)消減電(dian)(dian)(dian)(dian)池活性，直接(jie)導致鋰電(dian)(dian)(dian)(dian)池的(de)(de)快速老(lao)化。很多(duo)手機用(yong)戶可(ke)能都有這樣的(de)(de)經歷，明明顯示還有一格電(dian)(dian)(dian)(dian)量，可(ke)半個小時(shi)后，就(jiu)會(hui)顯示“電(dian)(dian)(dian)(dian)量低”，有時(shi)候還會(hui)自(zi)動關機。

所以在平時使用(yong)時，我們不必遵循“用(yong)盡(jin)、充滿”的(de)基本原(yuan)則。如(ru)果在檢測(ce)電(dian)路(lu)對(dui)電(dian)池檢測(ce)不準的(de)情況下(xia)，還遵守“用(yong)盡(jin)、充滿”的(de)基本原(yuan)則，那么電(dian)池的(de)壽(shou)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(wo)們在(zai)(zai)購(gou)買led手電(dian)(dian)筒的(de)(de)(de)時(shi)候(hou)，經銷店的(de)(de)(de)營業員都(dou)會(hui)囑咐(fu)，回去(qu)使用(yong)時(shi)要(yao)給電(dian)(dian)池(chi)用(yong)充(chong)(chong)(chong)電(dian)(dian)器充(chong)(chong)(chong)分(fen)充(chong)(chong)(chong)電(dian)(dian)和放電(dian)(dian)三次，這樣才(cai)能將鋰(li)(li)電(dian)(dian)池(chi)充(chong)(chong)(chong)分(fen)激(ji)活(huo)，保(bao)(bao)證以(yi)后鋰(li)(li)電(dian)(dian)池(chi)的(de)(de)(de)使用(yong)效能。在(zai)(zai)初次使用(yong)鋰(li)(li)電(dian)(dian)池(chi)的(de)(de)(de)時(shi)候(hou)，出廠的(de)(de)(de)鋰(li)(li)電(dian)(dian)池(chi)都(dou)帶有一(yi)定的(de)(de)(de)電(dian)(dian)量，所以(yi)說激(ji)活(huo)工(gong)作(zuo)已經在(zai)(zai)工(gong)廠內就(jiu)完(wan)成了。其實在(zai)(zai)工(gong)藝(yi)上(shang)，鋰(li)(li)電(dian)(dian)池(chi)激(ji)活(huo)的(de)(de)(de)過(guo)程必(bi)須(xu)在(zai)(zai)沒有“過(guo)充(chong)(chong)(chong)電(dian)(dian)”保(bao)(bao)護(hu)電(dian)(dian)路存在(zai)(zai)的(de)(de)(de)情況下完(wan)成。而現在(zai)(zai)使用(yong)的(de)(de)(de)鋰(li)(li)電(dian)(dian)池(chi)內部都(dou)有自己的(de)(de)(de)保(bao)(bao)護(hu)電(dian)(dian)路，而且充(chong)(chong)(chong)電(dian)(dian)器內部也有“過(guo)充(chong)(chong)(chong)電(dian)(dian)”保(bao)(bao)護(hu)電(dian)(dian)路。所以(yi)說按照店家(jia)所介(jie)紹的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)方法來激(ji)活(huo)鋰(li)(li)電(dian)(dian)池(chi)根本就(jiu)無從談起。

所(suo)以，不必(bi)對(dui)電池(chi)(chi)進行十幾(ji)個(ge)小時(shi)的(de)(de)充電來激活電池(chi)(chi)活性。但如果是(shi)由于長時(shi)間的(de)(de)擱(ge)置(zhi)，鋰電池(chi)(chi)活性會有一定程度的(de)(de)減(jian)少，所(suo)以在(zai)使用的(de)(de)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)(ban)都是(shi)采用18650鋰電(dian)池已經成為(wei)了主流，而市場上的(de)防爆手電(dian)筒電(dian)池假的(de)占有多少(shao)，一般(ban)(ban)分(fen)為(wei)幾類

1、虛假容量：

目前中(zhong)國18650電(dian)池技術就在2200容量(liang)，而很多銷售商為(wei)了(le)吸引消(xiao)費者(zhe)，將底容量(liang)電(dian)池虛假(jia)的打上(shang)3000或者(zhe)3200容量(liang)等，欺騙消(xiao)費者(zhe)，牟(mou)取(qu)更多的利益。

2、翻新電池：

翻(fan)新(xin)(xin)電(dian)池(chi)來(lai)源于國外拆機電(dian)池(chi)，通過一些非法渠道獲(huo)得(de)，然后翻(fan)新(xin)(xin)，打上虛假容量(liang)，這累電(dian)池(chi)是非常危(wei)險，消(xiao)(xiao)費(fei)者是隨身帶(dai)上一棵(ke)定(ding)時爆炸物(wu)在(zai)身邊，還(huan)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)這兩個(ge)字(zi)相信大家都熟(shu)悉不過的(de)(de)，鋰(li)(li)電(dian)池是一類由鋰(li)(li)金屬(shu)或(huo)鋰(li)(li)合(he)金為負極材料、使(shi)用(yong)非(fei)(fei)水(shui)電(dian)解質溶液(ye)的(de)(de)電(dian)池，鋰(li)(li)金屬(shu)的(de)(de)化學特性非(fei)(fei)常(chang)活潑，使(shi)得鋰(li)(li)金屬(shu)的(de)(de)加(jia)工、保存、使(shi)用(yong)，對環境要求非(fei)(fei)常(chang)高。山(shan)寨(zhai)電(dian)池制造(zao)者(zhe)對這些要求可(ke)能(neng)完全會忽略掉，弄(nong)不好隨(sui)時有(you)危險(xian)的(de)(de)可(ke)能(neng)。

消費者在購買LED手電筒的(de)同(tong)時，千(qian)萬(wan)要注意以上情況(kuang)。到正規的(de)強光手(shou)電筒廠家(jia)購買有(you)保(bao)障，最好選(xuan)購品牌(pai)的(de)手(shou)電筒。
