一、強光手電筒一定要用匹配的鋰電池
用(yong)(yong)作強光手電(dian)筒(tong)(tong)光源的(de)(de)鋰(li)電(dian)池(chi)有(you)較多(duo)型號,常用(yong)(yong)的(de)(de)有(you)18650、17670、16340等,首先(xian)我們要(yao)認識這些型號表(biao)達的(de)(de)意思,電(dian)池(chi)型號前面(mian)兩位(wei)數表(biao)示(shi)的(de)(de)是(shi)電(dian)池(chi)直徑,后面(mian)三位(wei)數表(biao)示(shi)高(gao)度。以市場應用(yong)(yong)最(zui)成熟的(de)(de)18650鋰(li)電(dian)池(chi)來說(shuo),其直徑是(shi)18mm,高(gao)度是(shi)65mm;而(er)手電(dian)筒(tong)(tong)用(yong)(yong)的(de)(de)16340電(dian)池(chi)則是(shi)指直徑16mm,高(gao)度為(wei)34mm的(de)(de)鋰(li)電(dian)池(chi)。
既定電(dian)壓(ya)和放電(dian)電(dian)流的手電(dian)筒燈泡要求(qiu)鋰電(dian)池不能過流,更不能超壓(ya)。
對于0.85A的(de)燈泡來說,放(fang)電(dian)電(dian)流(liu)最(zui)好(hao)(hao)(hao)是0.85A,如(ru)果電(dian)流(liu)過小,手電(dian)筒可(ke)能會(hui)(hui)亮度不夠,如(ru)果電(dian)流(liu)過大(da)(da),又(you)可(ke)能因過流(liu)而損壞電(dian)池結(jie)構,所(suo)以,“匹配(pei)”最(zui)好(hao)(hao)(hao),既能獲得(de)最(zui)大(da)(da)的(de)亮度,也不會(hui)(hui)損害電(dian)池。比如(ru),給(gei)0.85A的(de)燈泡供電(dian),友來16340鋰電(dian)池的(de)電(dian)流(liu)就(jiu)不行,可(ke)能會(hui)(hui)在亮過幾(ji)分鐘之后突然變(bian)暗,如(ru)果采(cai)用具有較(jiao)大(da)(da)電(dian)流(liu)放(fang)電(dian)性能的(de)雷(lei)鷹16340鋰電(dian)池,放(fang)電(dian)效果就(jiu)會(hui)(hui)好(hao)(hao)(hao)許多。
7.2V燈(deng)泡應該使用兩只鋰電(dian)(dian)(dian)(dian)池(chi)串(chuan)聯(lian)供電(dian)(dian)(dian)(dian),因(yin)為鋰電(dian)(dian)(dian)(dian)池(chi)的額定電(dian)(dian)(dian)(dian)壓是(shi)3.6V~3.7V,兩只3.6V電(dian)(dian)(dian)(dian)池(chi)串(chuan)聯(lian)起(qi)來就(jiu)是(shi)7.2V,另一(yi)方面(mian),如果(guo)鋰電(dian)(dian)(dian)(dian)池(chi)串(chuan)聯(lian)起(qi)來的電(dian)(dian)(dian)(dian)壓高于燈(deng)泡電(dian)(dian)(dian)(dian)壓過多的話,這(zhe)就(jiu)是(shi)超(chao)壓運行,會導致燈(deng)泡被燒,所以(yi)(yi),以(yi)(yi)前使用鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)的手電(dian)(dian)(dian)(dian)筒,如果(guo)換成鋰電(dian)(dian)(dian)(dian)池(chi)一(yi)定要換燈(deng)泡,超(chao)壓運行可以(yi)(yi)使手電(dian)(dian)(dian)(dian)筒量度更高,但負面(mian)的作用就(jiu)是(shi)可能(neng)燒掉燈(deng)泡,得不償失,因(yin)此選擇手電(dian)(dian)(dian)(dian)筒一(yi)定要用6V以(yi)(yi)上的燈(deng)泡。
最后,就是(shi)(shi)手電(dian)(dian)筒鋰(li)電(dian)(dian)池的(de)充(chong)(chong)電(dian)(dian),鋰(li)電(dian)(dian)池充(chong)(chong)電(dian)(dian)器(qi)是(shi)(shi)根據電(dian)(dian)壓(ya)(ya)值(zhi)判(pan)斷電(dian)(dian)池是(shi)(shi)否滿電(dian)(dian)的(de),單節鋰(li)電(dian)(dian)池充(chong)(chong)電(dian)(dian)的(de)終止電(dian)(dian)壓(ya)(ya)是(shi)(shi)4.2V,你只要買的(de)是(shi)(shi)正(zheng)(zheng)宗充(chong)(chong)電(dian)(dian)器(qi),充(chong)(chong)電(dian)(dian)器(qi)就會(hui)自動充(chong)(chong)到4.2V,然后停止充(chong)(chong)電(dian)(dian)行為(wei)。這里強調(diao)指出,充(chong)(chong)電(dian)(dian)器(qi)的(de)正(zheng)(zheng)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(ke)否認(ren),強光手電筒(tong)鋰(li)電池(chi)也有(you)記(ji)憶效(xiao)應(ying)(ying)(ying),但(dan)其(qi)記(ji)憶效(xiao)應(ying)(ying)(ying)是(shi)(shi)微乎其(qi)微的(de)(de),連制造商對此記(ji)憶效(xiao)應(ying)(ying)(ying)都(dou)忽(hu)略不記(ji),因此,在一(yi)些對鋰(li)電池(chi)產品的(de)(de)廣告中,可(ke)以看到廠(chang)商是(shi)(shi)打出“沒(mei)有(you)記(ji)憶效(xiao)應(ying)(ying)(ying),隨用(yong)(yong)隨充”的(de)(de)牌子。但(dan)在實際使(shi)用(yong)(yong)中,大(da)家也許會發(fa)覺,鋰(li)電池(chi)使(shi)用(yong)(yong)的(de)(de)時間會越來越短。這是(shi)(shi)怎(zen)么回事呢?其(qi)實,鋰(li)電池(chi)的(de)(de)制作材料(liao)是(shi)(shi)一(yi)種(zhong)活(huo)性(xing)物質,活(huo)性(xing)物質都(dou)會老化。而(er)制作鋰(li)電池(chi)的(de)(de)材料(liao),對于使(shi)用(yong)(yong)頻繁的(de)(de)程度和使(shi)用(yong)(yong)環境、溫度等(deng)等(deng)條件都(dou)比較敏感(gan)。
一般led手(shou)電筒鋰電池(chi)的使(shi)用壽命是充放(fang)電300~500次,電池(chi)的自然損耗會(hui)明顯縮短電池(chi)的持(chi)續(xu)使(shi)用時(shi)(shi)(shi)間。而對過度(du)的充電和過度(du)的放(fang)電,都會(hui)急速(su)的消減電池(chi)活性,直接導致鋰電池(chi)的快速(su)老化(hua)。很(hen)多手(shou)機用戶可(ke)能都有這樣(yang)的經歷,明明顯示還(huan)有一格電量,可(ke)半個小時(shi)(shi)(shi)后,就會(hui)顯示“電量低”,有時(shi)(shi)(shi)候還(huan)會(hui)自動(dong)關機。
所以在(zai)平時使用(yong)時,我們不必遵循“用(yong)盡(jin)(jin)、充(chong)滿”的(de)基本(ben)原則。如果在(zai)檢(jian)測(ce)電路對電池(chi)(chi)檢(jian)測(ce)不準的(de)情況下,還遵守“用(yong)盡(jin)(jin)、充(chong)滿”的(de)基本(ben)原則,那么電池(chi)(chi)的(de)壽命(ming)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(zai)購買led手電(dian)(dian)(dian)筒的(de)(de)時(shi)候,經銷店的(de)(de)營業員都會囑咐,回(hui)去使(shi)用(yong)時(shi)要給電(dian)(dian)(dian)池(chi)(chi)(chi)用(yong)充(chong)電(dian)(dian)(dian)器(qi)(qi)充(chong)分(fen)充(chong)電(dian)(dian)(dian)和放電(dian)(dian)(dian)三次,這樣才能(neng)將鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)分(fen)激活,保證以后鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)使(shi)用(yong)效能(neng)。在(zai)初次使(shi)用(yong)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)時(shi)候,出廠的(de)(de)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)都帶有(you)一定的(de)(de)電(dian)(dian)(dian)量,所以說(shuo)激活工作已經在(zai)工廠內就完成了。其實(shi)在(zai)工藝(yi)上,鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)激活的(de)(de)過(guo)程必須(xu)在(zai)沒有(you)“過(guo)充(chong)電(dian)(dian)(dian)”保護電(dian)(dian)(dian)路(lu)存在(zai)的(de)(de)情況下完成。而現在(zai)使(shi)用(yong)的(de)(de)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)內部都有(you)自己的(de)(de)保護電(dian)(dian)(dian)路(lu),而且充(chong)電(dian)(dian)(dian)器(qi)(qi)內部也有(you)“過(guo)充(chong)電(dian)(dian)(dian)”保護電(dian)(dian)(dian)路(lu)。所以說(shuo)按(an)照店家(jia)所介紹的(de)(de)充(chong)電(dian)(dian)(dian)方(fang)法(fa)來(lai)激活鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)根本就無從談起。
所以(yi),不(bu)必對(dui)電(dian)(dian)池(chi)進(jin)行(xing)十幾(ji)個(ge)小時(shi)的(de)(de)充電(dian)(dian)來激活(huo)電(dian)(dian)池(chi)活(huo)性。但(dan)如果(guo)是由(you)于長時(shi)間的(de)(de)擱置,鋰電(dian)(dian)池(chi)活(huo)性會(hui)有(you)一定程度的(de)(de)減少,所以(yi)在使用的(de)(de)時(shi)候最好先將電(dian)(dian)池(chi)完全(quan)充電(dian)(dian)后(hou)再使用。
三、如何辨別強光手電筒鋰電池質量
Led強光手電筒一(yi)(yi)般(ban)都是采用18650鋰電池(chi)已經(jing)成為了主(zhu)流,而市場上(shang)的防爆(bao)手電筒電池(chi)假的占(zhan)有(you)多少,一(yi)(yi)般(ban)分為幾類
1、虛假容量:
目(mu)前中國18650電池技術就在(zai)2200容量(liang),而很多銷售(shou)商為(wei)了(le)吸引(yin)消費(fei)者(zhe),將(jiang)底容量(liang)電池虛(xu)假(jia)的打(da)上3000或(huo)者(zhe)3200容量(liang)等,欺騙消費(fei)者(zhe),牟取(qu)更多的利益。
2、翻新電池:
翻(fan)新電(dian)池來源于國外拆(chai)機電(dian)池,通過一些非法渠道(dao)獲得,然后翻(fan)新,打上虛(xu)假容量(liang),這(zhe)累電(dian)池是非常危險,消費者是隨身(shen)帶上一棵定時爆炸物在(zai)身(shen)邊,還請消費者擦亮(liang)眼(yan)睛(jing)消費。
3、山寨電池:
山(shan)寨這兩(liang)個字相信大家都熟(shu)悉不過的(de),鋰電(dian)池是一(yi)類(lei)由(you)鋰金屬(shu)(shu)或鋰合金為負極材(cai)料、使用非水(shui)電(dian)解質溶液的(de)電(dian)池,鋰金屬(shu)(shu)的(de)化學特性(xing)非常活潑,使得鋰金屬(shu)(shu)的(de)加工、保存、使用,對環境要求(qiu)非常高。山(shan)寨電(dian)池制造者對這些要求(qiu)可能完(wan)全(quan)會忽略掉(diao),弄不好隨時(shi)有危險的(de)可能。
消費者在購買LED手電筒的同時,千萬要注意以上情(qing)況(kuang)。到正(zheng)規的強光(guang)手電筒廠家購買有保障,最好選購品牌(pai)的手電筒。
