從常規3C類電子產品來說，絕大多數場合，有鎳氫電池這個選項的就選電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，標準五號七號電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)這種(zhong)能(neng)換的為佳。有(you)的場合選電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)會(hui)動力不足，比如(ru)某些電(dian)(dian)(dian)(dian)(dian)動牙刷，使(shi)用鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)版(ban)本的最強(qiang)勁(jing)，這是(shi)廠(chang)家產(chan)品定位（性(xing)能(neng)強(qiang)的新(xin)品用鋰電(dian)(dian)(dian)(dian)(dian)）或(huo)內部設計(ji)（沒有(you)DC-DC恒壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)路）的問題，不是(shi)鎳氫電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的錯。從電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)材料特性(xing)本身來(lai)分析(xi)，鎳氫電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)怕(pa)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)低，正負(fu)極(ji)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)越(yue)接近(jin)，正極(ji)使(shi)用的導電(dian)(dian)(dian)(dian)(dian)劑和負(fu)極(ji)使(shi)用的金屬電(dian)(dian)(dian)(dian)(dian)極(ji)就越(yue)會(hui)各自產(chan)生輕微的不可逆化學反(fan)應從而對(dui)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的壽命產(chan)生影響；鋰電(dian)(dian)(dian)(dian)(dian)怕(pa)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)高(gao)，電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)越(yue)高(gao)則電(dian)(dian)(dian)(dian)(dian)解液(ye)越(yue)容易分解并加劇正負(fu)極(ji)腐蝕。

通(tong)常在買鎳氫(qing)電(dian)池時看到(dao)的循環次(ci)數如果是基于JIS（日本工業規格）測試方法(fa)計算的，舊規格只要求(qiu)放(fang)(fang)電(dian)到(dao)40%，新版JIS要求(qiu)放(fang)(fang)電(dian)到(dao)0%，之前標2100循環的修正到(dao)600循環，鎳氫(qing)電(dian)池從滿(man)電(dian)開始(shi)充(chong)放(fang)(fang)電(dian)越淺，循環壽(shou)命就越呈指數級別上升。

鋰電池從(cong)越高的(de)電(dian)(dian)量開(kai)始(shi)放(fang)電(dian)(dian)，整個壽命(ming)(ming)周期放(fang)出的(de)總電(dian)(dian)量（單次(ci)放(fang)電(dian)(dian)量乘(cheng)以次(ci)數）越不如從(cong)更低(di)的(de)電(dian)(dian)壓開(kai)始(shi)放(fang)的(de)電(dian)(dian)量。放(fang)電(dian)(dian)循(xun)環(huan)的(de)最低(di)電(dian)(dian)壓則(ze)對結果(guo)沒(mei)有影(ying)響。因為(wei)(wei)鎳氫(qing)電(dian)(dian)池(chi)和鋰(li)電(dian)(dian)池(chi)的(de)這兩種截然不同的(de)特性，導致了鋰(li)電(dian)(dian)池(chi)盡量要在低(di)電(dian)(dian)量的(de)狀態下保存(cun)，而鎳氫(qing)電(dian)(dian)池(chi)盡量要充滿(man)保存(cun)。我們買的(de)手(shou)機電(dian)(dian)腦大(da)多在開(kai)箱之時電(dian)(dian)池(chi)并不是充滿(man)的(de)，就(jiu)是為(wei)(wei)了在庫存(cun)狀態下能較好(hao)地維持鋰(li)電(dian)(dian)池(chi)的(de)壽命(ming)(ming)。

問題是，除了筆記本電(dian)(dian)腦（排除少數低端(duan)型號）之外，絕大多數鋰電(dian)(dian)池用電(dian)(dian)器并沒(mei)有限制(zhi)鋰電(dian)(dian)池充(chong)(chong)電(dian)(dian)電(dian)(dian)量的功能，要充(chong)(chong)就是充(chong)(chong)到滿才(cai)會(hui)停，從而導致鋰電(dian)(dian)池在長期高電(dian)(dian)壓狀態(tai)下迅速(su)衰減，甚至(zhi)軟包鋰電(dian)(dian)池發生鼓(gu)包現象(xiang)產生安全隱患。

常見錯(cuo)誤使用方(fang)式鋰電(dian)(dian)(dian)電(dian)(dian)(dian)動牙(ya)刷，刷完牙(ya)就往充電(dian)(dian)(dian)底座上(shang)一(yi)(yi)丟，馬上(shang)繼(ji)續充滿(man)；筆記本電(dian)(dian)(dian)腦，不開充電(dian)(dian)(dian)電(dian)(dian)(dian)量限(xian)制功能(neng)(neng)，長(chang)期(qi)(qi)插電(dian)(dian)(dian)源使用；索尼和蘋(pin)果品牌(pai)之外的(de)手機，睡(shui)覺前插上(shang)電(dian)(dian)(dian)源充電(dian)(dian)(dian)；移動電(dian)(dian)(dian)源和手機充電(dian)(dian)(dian)器一(yi)(yi)體機，長(chang)期(qi)(qi)插電(dian)(dian)(dian)當(dang)普通充電(dian)(dian)(dian)器用；任天堂Switch，長(chang)期(qi)(qi)存放在Dock里(li)以便隨時(shi)打開電(dian)(dian)(dian)視玩……另外還有(you)一(yi)(yi)些耗電(dian)(dian)(dian)量很低的(de)設(she)備，比如用鋰電(dian)(dian)(dian)的(de)遙控器、國產無(wu)線(xian)機械鍵(jian)盤(pan)和一(yi)(yi)次(ci)充電(dian)(dian)(dian)能(neng)(neng)用幾十天的(de)電(dian)(dian)(dian)動牙(ya)刷等，雖然一(yi)(yi)般不會長(chang)期(qi)(qi)插著電(dian)(dian)(dian)源使用，但(dan)一(yi)(yi)次(ci)充滿(man)之后(hou)會有(you)相當(dang)一(yi)(yi)段時(shi)間(jian)維持較高電(dian)(dian)(dian)壓，同樣(yang)會大幅縮減電(dian)(dian)(dian)池壽命。所以保持鋰電(dian)(dian)(dian)池使用壽命是很麻煩(fan)的(de)事情，絕(jue)大多數情況(kuang)下(xia)需要靠人肉(rou)操作(zuo)。
