一、強光手電筒一定要用匹配的鋰電池
用作強光(guang)手電(dian)(dian)筒光(guang)源的(de)鋰(li)電(dian)(dian)池有(you)較多型號,常用的(de)有(you)18650、17670、16340等,首先(xian)我們要認識這些型號表達的(de)意思,電(dian)(dian)池型號前面兩位(wei)數表示的(de)是(shi)電(dian)(dian)池直(zhi)(zhi)徑,后(hou)面三(san)位(wei)數表示高度。以市場(chang)應用最成熟的(de)18650鋰(li)電(dian)(dian)池來說,其直(zhi)(zhi)徑是(shi)18mm,高度是(shi)65mm;而手電(dian)(dian)筒用的(de)16340電(dian)(dian)池則是(shi)指直(zhi)(zhi)徑16mm,高度為34mm的(de)鋰(li)電(dian)(dian)池。
既定電(dian)壓(ya)和放電(dian)電(dian)流(liu)的(de)手電(dian)筒燈泡要求(qiu)鋰電(dian)池不能過流(liu),更不能超壓(ya)。
對于0.85A的(de)燈泡來(lai)(lai)說,放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)最(zui)(zui)好(hao)是0.85A,如果電(dian)(dian)(dian)流(liu)過(guo)(guo)小,手電(dian)(dian)(dian)筒可(ke)能(neng)會亮(liang)度不夠,如果電(dian)(dian)(dian)流(liu)過(guo)(guo)大(da),又可(ke)能(neng)因過(guo)(guo)流(liu)而損壞電(dian)(dian)(dian)池(chi)(chi)結構,所以,“匹配(pei)”最(zui)(zui)好(hao),既(ji)能(neng)獲得最(zui)(zui)大(da)的(de)亮(liang)度,也不會損害電(dian)(dian)(dian)池(chi)(chi)。比(bi)如,給(gei)0.85A的(de)燈泡供電(dian)(dian)(dian),友來(lai)(lai)16340鋰電(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)流(liu)就不行,可(ke)能(neng)會在亮(liang)過(guo)(guo)幾分鐘之后突然變暗,如果采(cai)用具有較大(da)電(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)性能(neng)的(de)雷鷹(ying)16340鋰電(dian)(dian)(dian)池(chi)(chi),放電(dian)(dian)(dian)效(xiao)果就會好(hao)許多。
7.2V燈泡(pao)(pao)應該(gai)使用(yong)兩只鋰(li)電(dian)(dian)(dian)池(chi)串(chuan)聯(lian)供電(dian)(dian)(dian),因為鋰(li)電(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)額定(ding)電(dian)(dian)(dian)壓(ya)是3.6V~3.7V,兩只3.6V電(dian)(dian)(dian)池(chi)串(chuan)聯(lian)起(qi)(qi)來就是7.2V,另一(yi)方(fang)面(mian),如果鋰(li)電(dian)(dian)(dian)池(chi)串(chuan)聯(lian)起(qi)(qi)來的(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)高于燈泡(pao)(pao)電(dian)(dian)(dian)壓(ya)過多的(de)(de)(de)(de)話,這就是超(chao)壓(ya)運(yun)行,會導致燈泡(pao)(pao)被燒,所以(yi),以(yi)前使用(yong)鎳氫電(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)手電(dian)(dian)(dian)筒(tong),如果換(huan)成鋰(li)電(dian)(dian)(dian)池(chi)一(yi)定(ding)要換(huan)燈泡(pao)(pao),超(chao)壓(ya)運(yun)行可以(yi)使手電(dian)(dian)(dian)筒(tong)量度更高,但負面(mian)的(de)(de)(de)(de)作用(yong)就是可能(neng)燒掉燈泡(pao)(pao),得不償失,因此選擇(ze)手電(dian)(dian)(dian)筒(tong)一(yi)定(ding)要用(yong)6V以(yi)上的(de)(de)(de)(de)燈泡(pao)(pao)。
最后(hou),就(jiu)(jiu)是手電(dian)(dian)(dian)(dian)筒鋰(li)電(dian)(dian)(dian)(dian)池(chi)的充(chong)電(dian)(dian)(dian)(dian),鋰(li)電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)器(qi)是根(gen)據電(dian)(dian)(dian)(dian)壓值判斷電(dian)(dian)(dian)(dian)池(chi)是否滿電(dian)(dian)(dian)(dian)的,單節鋰(li)電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)的終止(zhi)電(dian)(dian)(dian)(dian)壓是4.2V,你只要(yao)買的是正(zheng)宗(zong)充(chong)電(dian)(dian)(dian)(dian)器(qi),充(chong)電(dian)(dian)(dian)(dian)器(qi)就(jiu)(jiu)會自(zi)動充(chong)到4.2V,然后(hou)停止(zhi)充(chong)電(dian)(dian)(dian)(dian)行(xing)為。這里強調指(zhi)出,充(chong)電(dian)(dian)(dian)(dian)器(qi)的正(zheng)宗(zong)很重要(yao)。
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
不可否認,強光手(shou)電筒(tong)鋰電池(chi)也(ye)有記憶(yi)(yi)效應,但其(qi)記憶(yi)(yi)效應是(shi)微(wei)(wei)乎(hu)其(qi)微(wei)(wei)的(de),連(lian)制(zhi)造(zao)商對此記憶(yi)(yi)效應都忽(hu)略不記,因此,在一些對鋰電池(chi)產(chan)品的(de)廣告中,可以看到廠商是(shi)打出“沒有記憶(yi)(yi)效應,隨用隨充”的(de)牌(pai)子。但在實際使(shi)(shi)用中,大家也(ye)許會發覺,鋰電池(chi)使(shi)(shi)用的(de)時間(jian)會越來(lai)越短。這是(shi)怎么回事呢?其(qi)實,鋰電池(chi)的(de)制(zhi)作(zuo)(zuo)材(cai)料(liao)是(shi)一種活(huo)性(xing)物(wu)質,活(huo)性(xing)物(wu)質都會老化。而制(zhi)作(zuo)(zuo)鋰電池(chi)的(de)材(cai)料(liao),對于使(shi)(shi)用頻(pin)繁(fan)的(de)程度(du)和使(shi)(shi)用環(huan)境、溫度(du)等等條件都比較敏感。
一般led手(shou)電(dian)(dian)筒(tong)鋰電(dian)(dian)池(chi)的(de)使用(yong)壽命(ming)是(shi)充放電(dian)(dian)300~500次,電(dian)(dian)池(chi)的(de)自然損耗會(hui)明顯(xian)(xian)縮(suo)短電(dian)(dian)池(chi)的(de)持續使用(yong)時(shi)(shi)間。而(er)對過度的(de)充電(dian)(dian)和過度的(de)放電(dian)(dian),都會(hui)急速的(de)消減(jian)電(dian)(dian)池(chi)活性,直(zhi)接導致鋰電(dian)(dian)池(chi)的(de)快(kuai)速老化。很多手(shou)機(ji)(ji)用(yong)戶(hu)可(ke)能都有(you)這樣的(de)經歷,明明顯(xian)(xian)示還(huan)有(you)一格電(dian)(dian)量,可(ke)半個小時(shi)(shi)后,就會(hui)顯(xian)(xian)示“電(dian)(dian)量低”,有(you)時(shi)(shi)候還(huan)會(hui)自動關機(ji)(ji)。
所以在平時使用時,我們(men)不必(bi)遵循“用盡(jin)、充滿”的基本(ben)原(yuan)則。如果(guo)在檢測(ce)電(dian)路對電(dian)池檢測(ce)不準的情況(kuang)下,還(huan)遵守“用盡(jin)、充滿”的基本(ben)原(yuan)則,那么電(dian)池的壽命就不長(chang)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(gou)買led手電(dian)(dian)(dian)筒(tong)的(de)時(shi)候(hou),經(jing)銷(xiao)店的(de)營業員都會(hui)囑咐,回(hui)去使(shi)用(yong)時(shi)要給(gei)電(dian)(dian)(dian)池(chi)(chi)用(yong)充(chong)(chong)(chong)電(dian)(dian)(dian)器充(chong)(chong)(chong)分充(chong)(chong)(chong)電(dian)(dian)(dian)和放電(dian)(dian)(dian)三次(ci)(ci),這樣才能將鋰(li)電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)分激(ji)(ji)活(huo),保證(zheng)以(yi)(yi)后鋰(li)電(dian)(dian)(dian)池(chi)(chi)的(de)使(shi)用(yong)效(xiao)能。在(zai)初次(ci)(ci)使(shi)用(yong)鋰(li)電(dian)(dian)(dian)池(chi)(chi)的(de)時(shi)候(hou),出廠的(de)鋰(li)電(dian)(dian)(dian)池(chi)(chi)都帶有(you)一(yi)定的(de)電(dian)(dian)(dian)量,所以(yi)(yi)說(shuo)激(ji)(ji)活(huo)工作已經(jing)在(zai)工廠內就(jiu)完成了。其實在(zai)工藝上,鋰(li)電(dian)(dian)(dian)池(chi)(chi)激(ji)(ji)活(huo)的(de)過程必須在(zai)沒有(you)“過充(chong)(chong)(chong)電(dian)(dian)(dian)”保護電(dian)(dian)(dian)路(lu)存在(zai)的(de)情(qing)況(kuang)下完成。而(er)現在(zai)使(shi)用(yong)的(de)鋰(li)電(dian)(dian)(dian)池(chi)(chi)內部都有(you)自(zi)己的(de)保護電(dian)(dian)(dian)路(lu),而(er)且充(chong)(chong)(chong)電(dian)(dian)(dian)器內部也有(you)“過充(chong)(chong)(chong)電(dian)(dian)(dian)”保護電(dian)(dian)(dian)路(lu)。所以(yi)(yi)說(shuo)按照店家所介紹的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)方法來激(ji)(ji)活(huo)鋰(li)電(dian)(dian)(dian)池(chi)(chi)根本就(jiu)無從(cong)談起。
所(suo)(suo)以(yi),不必對(dui)電池(chi)進行十幾(ji)個小時(shi)的(de)(de)充電來激活(huo)電池(chi)活(huo)性。但(dan)如(ru)果(guo)是由于(yu)長時(shi)間(jian)的(de)(de)擱置(zhi),鋰電池(chi)活(huo)性會有一定程度的(de)(de)減少,所(suo)(suo)以(yi)在使用(yong)的(de)(de)時(shi)候最好先將電池(chi)完全充電后再(zai)使用(yong)。
三、如何辨別強光手電筒鋰電池質量
Led強光手電筒(tong)一般(ban)都(dou)是采用18650鋰電池(chi)已經成(cheng)為了主流(liu),而(er)市場上的防(fang)爆(bao)手電筒(tong)電池(chi)假(jia)的占有(you)多少,一般(ban)分為幾類
1、虛假容量:
目前中(zhong)國(guo)18650電(dian)池(chi)技術(shu)就在2200容量,而很多(duo)銷售(shou)商為了吸(xi)引(yin)消費(fei)(fei)者(zhe),將底容量電(dian)池(chi)虛假的打上3000或者(zhe)3200容量等,欺騙消費(fei)(fei)者(zhe),牟取更多(duo)的利益。
2、翻新電池:
翻(fan)新電池(chi)來源于(yu)國外拆機電池(chi),通過(guo)一(yi)些非(fei)法(fa)渠(qu)道獲(huo)得,然后翻(fan)新,打上(shang)虛(xu)假容量,這(zhe)累電池(chi)是(shi)非(fei)常危險,消(xiao)(xiao)費(fei)者是(shi)隨身帶上(shang)一(yi)棵定時爆(bao)炸物(wu)在身邊,還請消(xiao)(xiao)費(fei)者擦(ca)亮眼睛消(xiao)(xiao)費(fei)。
3、山寨電池:
山(shan)寨這兩個字(zi)相信大家都熟悉不(bu)過(guo)的(de),鋰電(dian)(dian)池是一類由(you)鋰金(jin)(jin)屬或鋰合金(jin)(jin)為負極(ji)材料、使(shi)用非水電(dian)(dian)解質(zhi)溶液的(de)電(dian)(dian)池,鋰金(jin)(jin)屬的(de)化學(xue)特性非常活潑,使(shi)得鋰金(jin)(jin)屬的(de)加工、保存、使(shi)用,對(dui)環境要(yao)(yao)求非常高。山(shan)寨電(dian)(dian)池制造(zao)者(zhe)對(dui)這些要(yao)(yao)求可能(neng)完全會(hui)忽(hu)略(lve)掉,弄不(bu)好(hao)隨(sui)時有(you)危險(xian)的(de)可能(neng)。
消費者在購買LED手電筒的(de)同時,千萬要(yao)注(zhu)意以(yi)上情況。到正規的(de)強(qiang)光手電(dian)筒廠(chang)家(jia)購(gou)買有保障,最好選(xuan)購(gou)品牌的(de)手電(dian)筒。
