筆(bi)記(ji)本電池充(chong)電時間(jian)(jian)注意，到底筆(bi)記(ji)本要(yao)充(chong)電多少時間(jian)(jian)才是(shi)正確的，在(zai)充(chong)電過程只能夠要(yao)把握什么？時間(jian)(jian)多少是(shi)否會影(ying)響筆(bi)記(ji)本電池的使(shi)用壽命(ming)呢(ni)？下面就這些問題擴展(zhan)開(kai)，看看對于筆(bi)記(ji)本中最(zui)脆弱的筆(bi)記(ji)本有什么可以注意的地方。

筆記本電池充電時間

謠傳一：新電池的激(ji)活

新電池應該用循環充放電的方式(shi)來(lai)激(ji)活電池的性(xing)能。

真相：準(zhun)確地說上(shang)述說法并不是(shi)謠傳。因(yin)(yin)為有(you)的(de)筆記本電(dian)(dian)(dian)(dian)池(chi)從生(sheng)產以(yi)后到客戶的(de)手里(li)會(hui)有(you)一(yi)(yi)定的(de)時間差(cha)，短(duan)則(ze)一(yi)(yi)個(ge)月，多則(ze)半年。對于時間差(cha)較長的(de)電(dian)(dian)(dian)(dian)池(chi)，其電(dian)(dian)(dian)(dian)極材料會(hui)鈍(dun)化(hua)，因(yin)(yin)此廠商建(jian)議(yi)初次使(shi)用的(de)電(dian)(dian)(dian)(dian)池(chi)最好進行3~5次完(wan)全充(chong)(chong)放(fang)(fang)電(dian)(dian)(dian)(dian)過程，以(yi)便消除電(dian)(dian)(dian)(dian)極材料的(de)鈍(dun)化(hua)，達到最大容(rong)量。但一(yi)(yi)般(ban)的(de)這里(li)的(de)充(chong)(chong)放(fang)(fang)電(dian)(dian)(dian)(dian)不是(shi)深度(du)放(fang)(fang)電(dian)(dian)(dian)(dian)，而是(shi)淺放(fang)(fang)電(dian)(dian)(dian)(dian)，這里(li)就有(you)一(yi)(yi)個(ge)筆記本電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)時間的(de)把握問題(ti)了。

筆記本(ben)電池(chi)“前(qian)三次”充電

謠傳二：當一(yi)款新的電(dian)池買回來以后，一(yi)般會說(shuo)最好進行三次循環充放電(dian)，而筆(bi)記本電(dian)池充電(dian)放電(dian)時(shi)間應(ying)該超過12小(xiao)時(shi)，以便激活電(dian)池最大效能。

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(de)(de)“恒流”、“恒壓”充電(dian)(dian)特性(xing)更是將其深充電(dian)(dian)時間控制在4小時以內。一旦充滿，電(dian)(dian)池(chi)內部的(de)(de)保(bao)護(hu)電(dian)(dian)路便(bian)會自動(dong)停止充電(dian)(dian)，因此這種做法是不科學也沒有(you)實際意(yi)義的(de)(de)。

有人(ren)曾(ceng)用手機做過(guo)試驗。在(zai)用旅充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)將(jiang)電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)(chong)(chong)(chong)滿(man)后，轉用座充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)來(lai)確認電(dian)(dian)(dian)池(chi)(chi)的飽(bao)和(he)(he)(he)程(cheng)度(du)。當他發現(xian)座充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)仍然(ran)(ran)對電(dian)(dian)(dian)池(chi)(chi)進行充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時，便認為電(dian)(dian)(dian)池(chi)(chi)仍未達(da)到(dao)(dao)飽(bao)和(he)(he)(he)狀態(tai)(tai)。其(qi)實(shi)這(zhe)個測(ce)試方(fang)法欠缺嚴謹。原因(yin)在(zai)于，座充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)的指(zhi)示燈并不(bu)是(shi)檢(jian)測(ce)真正飽(bao)和(he)(he)(he)與否的惟一(yi)標準(zhun)，座充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)的基準(zhun)電(dian)(dian)(dian)壓不(bu)一(yi)定等于手機的基準(zhun)電(dian)(dian)(dian)壓，因(yin)此當手機認為電(dian)(dian)(dian)池(chi)(chi)達(da)到(dao)(dao)飽(bao)和(he)(he)(he)狀態(tai)(tai)時，座充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)也許并不(bu)這(zhe)么認為，依然(ran)(ran)進行充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，但是(shi)否充(chong)(chong)(chong)(chong)(chong)(chong)進去，就只有它自己知道了(le)。

只要筆記本電(dian)池(chi)充電(dian)時間(jian)放電(dian)時間(jian)把握得(de)當，則有(you)可能會達(da)到最(zui)佳狀態

謠傳(chuan)三(san)：只要充電電池使用得當(dang)，就會在某一(yi)段循(xun)環范圍(wei)內出現(xian)最佳狀態，達到最大容量。

例如(ru)早期的(de)鎳(nie)氫(qing)、鎳(nie)鎘(ge)電池，如(ru)果使用(yong)得當，定期維護(hu)，會在15~203個循環(huan)點中達(da)到其(qi)容(rong)量的(de)最大值（出(chu)廠容(rong)量為(wei)1200mAh的(de)鎳(nie)氫(qing)電池在循環(huan)120次(ci)后，容(rong)量有可能達(da)到1200mAh）。

真相：這種說法在(zai)日(ri)系產品電(dian)池中(zhong)比(bi)較常(chang)見，在(zai)其技術規格書中(zhong)的循(xun)環(huan)特(te)性圖中(zhong)通(tong)常(chang)可(ke)以看(kan)到。然而對(dui)目前主流的鋰離子電(dian)池而言，這種循(xun)環(huan)的峰值現(xian)象(xiang)是不存在(zai)的。因為鋰離子電(dian)池從出(chu)廠到報廢，其容(rong)(rong)量的表現(xian)為循(xun)環(huan)一(yi)次少一(yi)次，從未出(chu)現(xian)過容(rong)(rong)量回升的現(xian)象(xiang)。也許有(you)朋友(you)會問，某些ThinkPad筆(bi)記本用戶通(tong)過深放電(dian)，可(ke)以恢復電(dian)池的容(rong)(rong)量。實(shi)際上那只是測試軟件(jian)的錯誤檢測而已，電(dian)池的實(shi)際容(rong)(rong)量根本沒有(you)提高。

筆(bi)(bi)記(ji)本電(dian)(dian)池(chi)使用時(shi)間正(zheng)確(que)的(de)影(ying)響(xiang)的(de)因素是筆(bi)(bi)記(ji)本電(dian)(dian)池(chi)所處的(de)環境(jing)的(de)溫度，當然(ran)筆(bi)(bi)記(ji)本充(chong)電(dian)(dian)時(shi)間也有一定的(de)關(guan)系，不過還是次于環境(jing)的(de)影(ying)響(xiang)。

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)26℃~41℃的(de)環(huan)境下會表現出極好的(de)性能。而到了(le)低溫或高溫狀態(tai)，其性能就要(yao)大打折扣(kou)了(le)。例如你在(zai)室外陽(yang)光(guang)直照的(de)情(qing)況(kuang)下使(shi)用(yong)筆記本電(dian)腦，就沒有在(zai)室內(nei)使(shi)用(yong)的(de)時間長。

謠傳四：兩個標(biao)稱(cheng)容(rong)量相(xiang)同（例如800mAh）的電(dian)池來說，如果一個實(shi)際測得容(rong)量為(wei)860mAh，另一個為(wei)805mAh，那么(me)860mAH的就一定(ding)比805mAh的好。

真相：一般而言，不同型號(hao)（不同體積(ji)）的(de)鋰離子(zi)電池，容(rong)(rong)量(liang)(liang)(liang)越(yue)高(gao)使用(yong)(yong)的(de)時間也就(jiu)(jiu)越(yue)長。如(ru)果(guo)拋開體積(ji)和重量(liang)(liang)(liang)等因(yin)素(su)，當(dang)然是(shi)容(rong)(rong)量(liang)(liang)(liang)越(yue)高(gao)越(yue)好。但對于(yu)兩(liang)個標稱容(rong)(rong)量(liang)(liang)(liang)相同（例如(ru)上(shang)例）的(de)電池卻未必。因(yin)為實際容(rong)(rong)量(liang)(liang)(liang)高(gao)的(de)那個電池，很(hen)可(ke)(ke)能在電極(ji)材料中添加了用(yong)(yong)于(yu)增加初始(shi)容(rong)(rong)量(liang)(liang)(liang)的(de)物質(zhi)(zhi)，減(jian)(jian)少了用(yong)(yong)于(yu)穩定電極(ji)的(de)物質(zhi)(zhi)。其結果(guo)就(jiu)(jiu)表現在循環了幾十次(ci)之(zhi)后(hou)，容(rong)(rong)量(liang)(liang)(liang)高(gao)的(de)那塊迅速衰減(jian)(jian)，而容(rong)(rong)量(liang)(liang)(liang)低的(de)卻依然堅挺。國內許(xu)多廠商(shang)(shang)為了縮減(jian)(jian)成本，擴大銷量(liang)(liang)(liang)，往往就(jiu)(jiu)采用(yong)(yong)了這種手段來生產高(gao)容(rong)(rong)量(liang)(liang)(liang)電池。用(yong)(yong)戶在使用(yong)(yong)半年后(hou)就(jiu)(jiu)會(hui)發現工作時間大為縮短(duan)。總之(zhi)，提高(gao)容(rong)(rong)量(liang)(liang)(liang)的(de)代價就(jiu)(jiu)是(shi)犧(xi)牲(sheng)循環壽命，廠商(shang)(shang)不在電池的(de)材料上(shang)下文章，是(shi)不可(ke)(ke)能真正提高(gao)電池容(rong)(rong)量(liang)(liang)(liang)

電池的保存

謠傳五：充電電池(chi)如果(guo)不使用，應該放光了電再保(bao)存。

真相：其實(shi)不僅(jin)僅(jin)有上面提(ti)到(dao)的(de)謠(yao)傳，鋰(li)離子電池(chi)到(dao)底該充滿了保存(cun)還是放光了保存(cun)肯定會讓很多(duo)人(ren)感到(dao)迷惑？這一(yi)問題的(de)解答要從(cong)其先天(tian)性的(de)缺陷(xian)談起，那就是“老化效應”。鋰(li)離子電池(chi)在存(cun)儲一(yi)段時(shi)間后(hou)，即使不進行循環使用，其部分(fen)容(rong)量也(ye)會永久性的(de)喪失，這是因為鋰(li)離子電池(chi)的(de)正負極材(cai)料自出廠時(shi)便開始了它們的(de)衰竭歷程(cheng)。不同的(de)溫(wen)度及飽和程(cheng)度下老化的(de)幅(fu)度也(ye)是不同的(de)，具(ju)體幅(fu)度可(ke)見表(biao)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(qi)保存(cun)(cun)，用(yong)戶應當將其(qi)電量(liang)控制(zhi)在40%，并存(cun)(cun)儲(chu)在15℃甚至更(geng)低的溫度下即可(ke)。至于那些鎳(nie)氫和(he)鎳(nie)鎘(ge)電池則不(bu)存(cun)(cun)在這一“老化(hua)效(xiao)應”，長(chang)期(qi)儲(chu)存(cun)(cun)后只需進行幾次完全充放電即可(ke)恢復其(qi)原始容量(liang)充滿電后續充

謠(yao)傳六(liu)：筆記本(ben)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)時間一(yi)般是有控制(zhi)的，對于筆記本(ben)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)充(chong)滿(man)以后，在繼(ji)續(xu)對電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)充(chong)1～2小時，這(zhe)樣做有利于增強電(dian)(dian)(dian)池的飽和度。

   其實現(xian)在的(de)筆(bi)記本而電(dian)(dian)池(chi)(chi)一般都有筆(bi)記本過電(dian)(dian)保(bao)護電(dian)(dian)路(lu)(lu)，充(chong)滿點以后他會自(zi)動切斷充(chong)電(dian)(dian)電(dian)(dian)路(lu)(lu)。所以充(chong)電(dian)(dian)時(shi)(shi)間是固定的(de)，滿了以后電(dian)(dian)源只對筆(bi)記本設備進(jin)行供電(dian)(dian)，即(ji)時(shi)(shi)電(dian)(dian)池(chi)(chi)再充(chong)12個小(xiao)時(shi)(shi)也是沒有用處的(de)。
