筆記(ji)本(ben)電池充電時間注意(yi)，到底筆記(ji)本(ben)要充電多少時間才是正確的(de)(de)，在(zai)充電過程只能夠要把握什么(me)？時間多少是否(fou)會影響筆記(ji)本(ben)電池的(de)(de)使用(yong)壽命呢？下面就這些問題(ti)擴展開，看(kan)看(kan)對于(yu)筆記(ji)本(ben)中最(zui)脆弱(ruo)的(de)(de)筆記(ji)本(ben)有什么(me)可以(yi)注意(yi)的(de)(de)地方。

筆記本電池充電時間

謠傳(chuan)一(yi)：新電池的激(ji)活(huo)

新電(dian)池(chi)應該用循環充放電(dian)的(de)方式來激(ji)活(huo)電(dian)池(chi)的(de)性能。

真相：準確地說(shuo)上(shang)述說(shuo)法(fa)并不是謠傳。因為有(you)的(de)筆記本電(dian)(dian)(dian)(dian)(dian)池(chi)從生(sheng)產以后到(dao)客戶的(de)手(shou)里會有(you)一(yi)定(ding)的(de)時(shi)(shi)(shi)間(jian)(jian)差，短則一(yi)個(ge)月(yue)，多則半年(nian)。對于時(shi)(shi)(shi)間(jian)(jian)差較長的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)，其(qi)電(dian)(dian)(dian)(dian)(dian)極材(cai)料(liao)會鈍(dun)化，因此廠商建議(yi)初次(ci)使用的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)最好(hao)進行3~5次(ci)完全(quan)充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)過程，以便消(xiao)除電(dian)(dian)(dian)(dian)(dian)極材(cai)料(liao)的(de)鈍(dun)化，達到(dao)最大(da)容量(liang)。但一(yi)般(ban)的(de)這里的(de)充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)不是深度放(fang)電(dian)(dian)(dian)(dian)(dian)，而(er)是淺放(fang)電(dian)(dian)(dian)(dian)(dian)，這里就(jiu)有(you)一(yi)個(ge)筆記本電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間(jian)(jian)的(de)把握問(wen)題了。

筆(bi)記本(ben)電池“前三次(ci)”充(chong)電

謠傳二：當一(yi)款(kuan)新的(de)電(dian)(dian)池(chi)買回來以(yi)后，一(yi)般會說最(zui)好進行三次循環充(chong)放電(dian)(dian)，而筆記本電(dian)(dian)池(chi)充(chong)電(dian)(dian)放電(dian)(dian)時(shi)間應該超過12小(xiao)時(shi)，以(yi)便激活(huo)電(dian)(dian)池(chi)最(zui)大效能。

真相：鎳氫電池為了達到最完美的飽和狀態，需要經過“補充”和“涓流”過程，這個時間一般在5小時左右。而目前鋰離子電池的“恒(heng)流”、“恒(heng)壓”充(chong)(chong)電(dian)特性更(geng)是(shi)將其深充(chong)(chong)電(dian)時(shi)間(jian)控制在(zai)4小時(shi)以內。一旦充(chong)(chong)滿，電(dian)池(chi)內部(bu)的保護電(dian)路(lu)便會自動停止充(chong)(chong)電(dian)，因(yin)此(ci)這種做法(fa)是(shi)不科學也(ye)沒有實際意義(yi)的。

有(you)人(ren)曾用(yong)(yong)手(shou)機做過(guo)試驗。在用(yong)(yong)旅充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器將電(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)(chong)(chong)(chong)滿(man)后，轉用(yong)(yong)座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器來確認電(dian)(dian)池(chi)(chi)的飽(bao)和(he)(he)程度(du)。當他發現座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器仍(reng)然對電(dian)(dian)池(chi)(chi)進行(xing)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)，便(bian)認為電(dian)(dian)池(chi)(chi)仍(reng)未達到飽(bao)和(he)(he)狀(zhuang)態。其實這個(ge)測試方法欠缺嚴謹。原因在于(yu)(yu)，座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器的指示燈并不是檢測真正飽(bao)和(he)(he)與否的惟一標準，座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器的基準電(dian)(dian)壓不一定等于(yu)(yu)手(shou)機的基準電(dian)(dian)壓，因此當手(shou)機認為電(dian)(dian)池(chi)(chi)達到飽(bao)和(he)(he)狀(zhuang)態時(shi)，座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器也(ye)許并不這么認為，依(yi)然進行(xing)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)，但是否充(chong)(chong)(chong)(chong)(chong)(chong)進去，就只有(you)它自己知道了。

只要筆記(ji)本電(dian)池充電(dian)時間放電(dian)時間把握得當(dang)，則有(you)可(ke)能會達到最佳狀態

謠(yao)傳三：只要(yao)充(chong)電(dian)電(dian)池使用得當，就會在某一(yi)段循環范圍內出現最佳狀(zhuang)態(tai)，達(da)到最大(da)容量。

例如早(zao)期的(de)鎳(nie)氫、鎳(nie)鎘電(dian)池，如果使用得當，定期維(wei)護，會在15~203個(ge)循環點中達(da)(da)到其容(rong)量的(de)最大值（出廠容(rong)量為(wei)1200mAh的(de)鎳(nie)氫電(dian)池在循環120次(ci)后，容(rong)量有(you)可(ke)能達(da)(da)到1200mAh）。

真相：這種說法在日(ri)系產品電池(chi)中比較常見，在其(qi)技術規格書中的(de)(de)(de)循(xun)(xun)環(huan)特性圖中通常可以看到。然而(er)對目前主流的(de)(de)(de)鋰離(li)子電池(chi)而(er)言，這種循(xun)(xun)環(huan)的(de)(de)(de)峰值現(xian)(xian)象(xiang)(xiang)是(shi)不存在的(de)(de)(de)。因(yin)為(wei)鋰離(li)子電池(chi)從(cong)出(chu)廠到報廢(fei)，其(qi)容量的(de)(de)(de)表(biao)現(xian)(xian)為(wei)循(xun)(xun)環(huan)一(yi)(yi)次少一(yi)(yi)次，從(cong)未出(chu)現(xian)(xian)過(guo)(guo)容量回升的(de)(de)(de)現(xian)(xian)象(xiang)(xiang)。也許有(you)朋友會問，某些ThinkPad筆記本(ben)用戶通過(guo)(guo)深放電，可以恢復電池(chi)的(de)(de)(de)容量。實際上那只是(shi)測(ce)試軟件(jian)的(de)(de)(de)錯(cuo)誤(wu)檢測(ce)而(er)已，電池(chi)的(de)(de)(de)實際容量根本(ben)沒有(you)提(ti)高。

筆記本(ben)電池(chi)(chi)使用時(shi)間正確的(de)(de)影響的(de)(de)因素是筆記本(ben)電池(chi)(chi)所處(chu)的(de)(de)環(huan)境的(de)(de)溫度，當(dang)然筆記本(ben)充(chong)電時(shi)間也有一定的(de)(de)關系(xi)，不過還是次于環(huan)境的(de)(de)影響。

鋰離子電池到底有沒有最佳狀態？答案是肯定的，這跟其所受環境溫度的變化有關。一般情況下，鋰離子電池在(zai)(zai)26℃~41℃的環境下(xia)會表現出極好的性(xing)能。而到了低(di)溫或高溫狀態，其性(xing)能就要大(da)打折扣了。例如你在(zai)(zai)室(shi)(shi)外陽光(guang)直照的情況下(xia)使用(yong)筆記本電腦(nao)，就沒有在(zai)(zai)室(shi)(shi)內使用(yong)的時間長。

謠傳(chuan)四：兩個標稱(cheng)容(rong)量相(xiang)同（例如(ru)800mAh）的電池來說，如(ru)果一(yi)個實際測得容(rong)量為860mAh，另一(yi)個為805mAh，那么860mAH的就(jiu)一(yi)定比805mAh的好。

真相：一般而(er)言，不(bu)(bu)同(tong)型號（不(bu)(bu)同(tong)體(ti)(ti)積(ji)）的(de)(de)鋰離子電(dian)池，容(rong)(rong)量(liang)(liang)(liang)(liang)越高(gao)(gao)使用(yong)(yong)的(de)(de)時間也就(jiu)越長。如(ru)果拋(pao)開體(ti)(ti)積(ji)和重量(liang)(liang)(liang)(liang)等因(yin)素，當然(ran)是(shi)(shi)容(rong)(rong)量(liang)(liang)(liang)(liang)越高(gao)(gao)越好。但對于兩個標稱容(rong)(rong)量(liang)(liang)(liang)(liang)相同(tong)（例(li)如(ru)上(shang)例(li)）的(de)(de)電(dian)池卻未必。因(yin)為(wei)實際容(rong)(rong)量(liang)(liang)(liang)(liang)高(gao)(gao)的(de)(de)那(nei)個電(dian)池，很可能在電(dian)極(ji)材料中添加了用(yong)(yong)于增加初(chu)始容(rong)(rong)量(liang)(liang)(liang)(liang)的(de)(de)物質，減(jian)(jian)少了用(yong)(yong)于穩(wen)定電(dian)極(ji)的(de)(de)物質。其(qi)結果就(jiu)表現在循環(huan)(huan)了幾十次之(zhi)后，容(rong)(rong)量(liang)(liang)(liang)(liang)高(gao)(gao)的(de)(de)那(nei)塊迅速(su)衰減(jian)(jian)，而(er)容(rong)(rong)量(liang)(liang)(liang)(liang)低的(de)(de)卻依然(ran)堅挺。國內(nei)許多(duo)廠(chang)商(shang)為(wei)了縮減(jian)(jian)成本(ben)，擴大(da)銷量(liang)(liang)(liang)(liang)，往往就(jiu)采用(yong)(yong)了這種手(shou)段來(lai)生產高(gao)(gao)容(rong)(rong)量(liang)(liang)(liang)(liang)電(dian)池。用(yong)(yong)戶在使用(yong)(yong)半(ban)年(nian)后就(jiu)會發現工作時間大(da)為(wei)縮短。總之(zhi)，提高(gao)(gao)容(rong)(rong)量(liang)(liang)(liang)(liang)的(de)(de)代價就(jiu)是(shi)(shi)犧(xi)牲(sheng)循環(huan)(huan)壽(shou)命，廠(chang)商(shang)不(bu)(bu)在電(dian)池的(de)(de)材料上(shang)下文章，是(shi)(shi)不(bu)(bu)可能真正提高(gao)(gao)電(dian)池容(rong)(rong)量(liang)(liang)(liang)(liang)

電池的保存

謠傳(chuan)五(wu)：充電電池如果不使(shi)用，應該(gai)放光(guang)了電再保存。

真相：其實不僅(jin)(jin)僅(jin)(jin)有上面提(ti)到的(de)(de)(de)(de)謠傳，鋰(li)(li)離子電(dian)池(chi)(chi)到底該充(chong)滿了(le)(le)保(bao)(bao)存(cun)還(huan)是(shi)(shi)(shi)放光了(le)(le)保(bao)(bao)存(cun)肯定(ding)會讓(rang)很多人感(gan)到迷惑？這一問題的(de)(de)(de)(de)解(jie)答要從其先天性(xing)(xing)的(de)(de)(de)(de)缺陷談起，那就是(shi)(shi)(shi)“老(lao)化(hua)效應(ying)”。鋰(li)(li)離子電(dian)池(chi)(chi)在存(cun)儲(chu)一段時間后，即使不進行循(xun)環使用，其部(bu)分容量也會永久性(xing)(xing)的(de)(de)(de)(de)喪失，這是(shi)(shi)(shi)因為鋰(li)(li)離子電(dian)池(chi)(chi)的(de)(de)(de)(de)正負(fu)極材料自出廠(chang)時便開始了(le)(le)它(ta)們的(de)(de)(de)(de)衰竭歷(li)程(cheng)。不同(tong)的(de)(de)(de)(de)溫度(du)(du)(du)及飽和程(cheng)度(du)(du)(du)下老(lao)化(hua)的(de)(de)(de)(de)幅度(du)(du)(du)也是(shi)(shi)(shi)不同(tong)的(de)(de)(de)(de)，具(ju)體幅度(du)(du)(du)可見表所示。

由此可見，存儲溫度越高、電池充的越滿，容量的幅度就越大。因此對于鋰離子電池的長(chang)期保存(cun)，用戶(hu)應(ying)當將其(qi)電(dian)量控制在(zai)40%，并存(cun)儲(chu)在(zai)15℃甚至更低(di)的溫度下即可(ke)。至于(yu)那(nei)些鎳氫和鎳鎘電(dian)池則不存(cun)在(zai)這(zhe)一(yi)“老化(hua)效應(ying)”，長(chang)期儲(chu)存(cun)后只需進行(xing)幾次完全充(chong)放電(dian)即可(ke)恢復其(qi)原始容量充(chong)滿電(dian)后續充(chong)

謠傳六：筆記(ji)本電(dian)池充(chong)(chong)(chong)電(dian)時(shi)間(jian)一般是(shi)有(you)控制的(de)(de)，對于筆記(ji)本電(dian)池充(chong)(chong)(chong)電(dian)充(chong)(chong)(chong)滿(man)以后，在繼續對電(dian)池充(chong)(chong)(chong)電(dian)充(chong)(chong)(chong)1～2小時(shi)，這樣做有(you)利于增強電(dian)池的(de)(de)飽和度。

   其(qi)實(shi)現在的筆(bi)(bi)記本而電(dian)(dian)池(chi)一般都(dou)有筆(bi)(bi)記本過電(dian)(dian)保護(hu)電(dian)(dian)路，充滿點以(yi)后(hou)他會自動切斷(duan)充電(dian)(dian)電(dian)(dian)路。所以(yi)充電(dian)(dian)時間(jian)是固定的，滿了以(yi)后(hou)電(dian)(dian)源只(zhi)對(dui)筆(bi)(bi)記本設備(bei)進行供(gong)電(dian)(dian)，即時電(dian)(dian)池(chi)再充12個小時也是沒(mei)有用處的。
