手機電池容量檢測方法
1、借助(zhu)針對手機的(de)專門測試電池(chi)容量的(de)軟件(jian),查看電池(chi)容量。
2、在保證測(ce)試(shi)過程是(shi)恒流的情況下(xia),選取跟要測(ce)試(shi)手(shou)機(ji)電(dian)阻(zu)(zu)相近的電(dian)阻(zu)(zu)與電(dian)流表(biao)串聯后,對充滿(man)電(dian)(4.2V)的電(dian)池進行(xing)放(fang)電(dian),直到3.7V結(jie)束(shu)。測(ce)量電(dian)流,并記錄(lu)時(shi)間。如(ru)記錄(lu)的電(dian)流是(shi)200mA,放(fang)電(dian)時(shi)間為4個小時(shi)。那么該電(dian)池容量為200X4=800mAh。
3、交由專(zhuan)業(ye)檢(jian)測部門進行(xing)檢(jian)測。
手機電池容量怎么計算?
鋰電(dian)(dian)池(chi)的充電(dian)(dian)方式(shi)是(shi)限壓橫流方式(shi),一般(ban)充電(dian)(dian)電(dian)(dian)流都設(she)定(ding)在0.2C。充放(fang)電(dian)(dian)電(dian)(dian)流一般(ban)用C作參照,C是(shi)對應(ying)電(dian)(dian)池(chi)容(rong)量(liang)的數值(zhi)。電(dian)(dian)池(chi)容(rong)量(liang)一般(ban)用mA表示,如L600的電(dian)(dian)池(chi)容(rong)量(liang)1800mAh,對應(ying)的C就是(shi)1800mA。 0.2C就等(deng)于(yu)240mA。
一(yi)(yi)般(ban)鋰電(dian)(dian)池(chi)充電(dian)(dian)電(dian)(dian)流都設定在0.2C ,按照這個原理,我們(men)就可以通(tong)過電(dian)(dian)池(chi)的(de)充電(dian)(dian)時間來計(ji)算一(yi)(yi)下(xia)手機電(dian)(dian)池(chi)的(de)大致容(rong)量。
以L600為例,來(lai)計算(suan)一下L600的電(dian)池(chi)(chi)(chi)容(rong)量:電(dian)池(chi)(chi)(chi)標注是1800毫(hao)安(an),按照“一般鋰電(dian)池(chi)(chi)(chi)充電(dian)電(dian)流設定(ding)在(zai)0.2C”計算(suan),0.2×1800=360,從L600的充電(dian)時(shi)間(jian)來(lai)看,L600電(dian)池(chi)(chi)(chi)充滿(man)的時(shi)間(jian)為近5小時(shi),即(ji)360×5=1800。這樣就基本計算(suan)出該手機電(dian)池(chi)(chi)(chi)的容(rong)量了。
可見(jian)本機電(dian)(dian)池容(rong)量(liang)與標(biao)注的(de)(de)(de)容(rong)量(liang)是(shi)相符的(de)(de)(de)。很多山寨機,電(dian)(dian)池容(rong)量(liang)標(biao)的(de)(de)(de)都非常(chang)大,有的(de)(de)(de)大的(de)(de)(de)驚人,在充電(dian)(dian)時(shi)很快就充滿了,一使用兩天就沒有電(dian)(dian)了。用這種(zhong)方法,大家就很容(rong)易判斷電(dian)(dian)池的(de)(de)(de)大致容(rong)量(liang)了。
什么手機電池好?
一、看容量
一般(ban)的(de)鎳(nie)(nie)(nie)鎘電(dian)池為500mAh或600mAh,鎳(nie)(nie)(nie)氫電(dian)池也不(bu)過(guo)800~900mAh;而鋰離子手(shou)機電(dian)池的(de)容量(liang)一般(ban)都在1300~1400mAh之間,所(suo)以鋰離子電(dian)池充(chong)足電(dian)后使(shi)用的(de)時間約是(shi)鎳(nie)(nie)(nie)氫電(dian)池的(de)1.5倍,是(shi)鎳(nie)(nie)(nie)鎘電(dian)池的(de)3.0倍左右。
二、看外觀
正品電(dian)池防磨面均(jun)勻,采用(yong)(yong)的(de)(de)是(shi)PC材質,無脆裂現象;假冒電(dian)池無防磨或過于粗糙,采用(yong)(yong)的(de)(de)是(shi)再生材質,易脆裂。正品的(de)(de)手(shou)機(ji)(ji)(ji)電(dian)池表(biao)面色(se)澤(ze)紋(wen)理清晰、均(jun)勻、干凈、無明(ming)顯劃痕及損傷。五金片無明(ming)顯劃痕及發(fa)黑(hei)、發(fa)綠現象,電(dian)池底(di)殼顏色(se)與(yu)手(shou)機(ji)(ji)(ji)機(ji)(ji)(ji)身一致(zhi),與(yu)手(shou)機(ji)(ji)(ji)配合良好,鎖扣可靠。
三、看標志
原裝(zhuang)電池標(biao)貼應(ying)印(yin)有電池型號、種類、額定容量(liang)、標(biao)準電壓、正負極標(biao)志、制造廠(chang)名。
四、看保護裝置
正品手機電(dian)池(chi)內(nei)部應有過(guo)(guo)流保(bao)護(hu)器,在外部短路等導(dao)致電(dian)流過(guo)(guo)大的(de)情況下,自動(dong)切(qie)斷回路,以免燒毀或損壞手機。如果(guo)在充電(dian)的(de)過(guo)(guo)程中,發現電(dian)池(chi)嚴重(zhong)發熱(re)、冒(mao)煙、甚至爆炸,說明電(dian)池(chi)肯定是假的(de)。
五、看防偽標志
如原裝電(dian)池的貼紙(zhi)下暗(an)(an)藏斜印品(pin)牌標(biao)志(zhi)字樣,一些品(pin)牌的防(fang)偽(wei)商標(biao)呈(cheng)菱(ling)形(xing),并(bing)且無論從任(ren)何(he)角度看,都(dou)閃爍(shuo)有立體效果。相反(fan),防(fang)偽(wei)標(biao)志(zhi)色澤暗(an)(an)淡(dan)、立體感不(bu)足,便(bian)有可能是(shi)假(jia)貨。
六、測電壓
如(ru)果用鎳(nie)鎘、鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)塊(kuai)假冒鋰離子手機(ji)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)塊(kuai),就(jiu)必須由5個(ge)單體(ti)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組成,單個(ge)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓一般不超過1.55V,當電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)塊(kuai)的充電(dian)(dian)(dian)(dian)(dian)總(zong)電(dian)(dian)(dian)(dian)(dian)壓低(di)于8.0V時就(jiu)有可能是鎳(nie)鎘、鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。
