1.充電器要匹配：如果更換充電器或者電(dian)池的(de)(de)時候(hou)，最好請專業維修人員推薦(jian)。不要過(guo)多(duo)關心那些數據，因為一(yi)般(ban)充(chong)電(dian)器都(dou)是設(she)定好的(de)(de)，但(dan)(dan)是電(dian)池是一(yi)個動態(tai)的(de)(de)壽命(ming)過(guo)程，嚴格(ge)講目前市(shi)(shi)場(chang)上(shang)沒有(you)足夠(gou)保證充(chong)電(dian)質量的(de)(de)充(chong)電(dian)器。但(dan)(dan)是一(yi)分價錢一(yi)分貨，好的(de)(de)充(chong)電(dian)器絕(jue)對對電(dian)池有(you)好的(de)(de)充(chong)電(dian)效果，估計南京市(shi)(shi)場(chang)的(de)(de)市(shi)(shi)場(chang)價格(ge)要在75元以上(shang)才能算好一(yi)點的(de)(de)充(chong)電(dian)器（有(you)待核實(shi)，呵呵）

2.“勤充淺放”，就(jiu)是每(mei)次(ci)用過后有條(tiao)件(jian)就(jiu)充電，同時(shi)盡量不要一(yi)次(ci)用到(dao)欠壓再充電（這應該(gai)屬于使(shi)用方法(fa)），每(mei)次(ci)都(dou)充滿，實(shi)在(zai)來不及(ji)充不滿那也沒有辦法(fa)，以實(shi)用為(wei)標(biao)準(zhun)嗎，不能為(wei)物所累！

3.一般情況下，充滿的參考是：按照充電器轉燈以后1個小時左右，不超過2小時為最好。這個要根據電池的新舊程度，充電器一般是(shi)按照8～10小(xiao)時(shi)(shi)(shi)充(chong)(chong)滿（指的(de)(de)(de)是(shi)騎行了較(jiao)遠，電(dian)池(chi)放電(dian)接近(jin)欠壓的(de)(de)(de)情(qing)況(kuang)）設計的(de)(de)(de)，目前市場(chang)上也有(you)8小(xiao)時(shi)(shi)(shi)后自動停(ting)充(chong)(chong)的(de)(de)(de)（這有(you)欠充(chong)(chong)的(de)(de)(de)危險，呵(he)(he)呵(he)(he)），注意有(you)點維修人員(yuan)所說(shuo)新電(dian)池(chi)要充(chong)(chong)足12小(xiao)時(shi)(shi)(shi)以上的(de)(de)(de)說(shuo)法是(shi)不(bu)恰當的(de)(de)(de)。要根據(ju)使用情(qing)況(kuang)和(he)自己的(de)(de)(de)情(qing)況(kuang)，比如白(bai)天騎行里程(cheng)長，就多充(chong)(chong)一會兒，騎行的(de)(de)(de)里程(cheng)短，就少充(chong)(chong)一會兒，或者說(shuo)睡覺(jue)前掌握充(chong)(chong)電(dian)時(shi)(shi)(shi)間早晚有(you)個參考(kao)，不(bu)至(zhi)于為了十分精確的(de)(de)(de)時(shi)(shi)(shi)間半夜起(qi)床吧，呵(he)(he)呵(he)(he)。

4.按(an)照國(guo)際電(dian)(dian)池(chi)(chi)(chi)屆的(de)(de)新理論，最好(hao)是(shi)(shi)每7~15次(ci)充(chong)電(dian)(dian)，進(jin)行一(yi)(yi)次(ci)盡充(chong)盡放(fang)，這(zhe)(zhe)樣，有利于(yu)提高(gao)電(dian)(dian)池(chi)(chi)(chi)的(de)(de)容量，延(yan)長電(dian)(dian)池(chi)(chi)(chi)的(de)(de)壽(shou)(shou)命。這(zhe)(zhe)個(ge)方(fang)法(fa)(fa)建(jian)議大家了(le)解就(jiu)行，因為搞(gao)不(bu)好(hao)就(jiu)會(hui)(hui)出現不(bu)良后(hou)果，呵(he)呵(he)。如是(shi)(shi)專業人員或者特別愛好(hao)才可以(yi)一(yi)(yi)試：盡放(fang)的(de)(de)方(fang)法(fa)(fa)比(bi)較簡(jian)單，就(jiu)是(shi)(shi)騎行車(che)到(dao)第一(yi)(yi)次(ci)指示斷電(dian)(dian)。一(yi)(yi)般的(de)(de)電(dian)(dian)動自(zi)行車(che)均有欠壓(ya)保(bao)護(hu)(hu)，對于(yu)標稱36V的(de)(de)電(dian)(dian)動自(zi)行車(che)來說，多數控制器(qi)的(de)(de)欠壓(ya)保(bao)護(hu)(hu)電(dian)(dian)壓(ya)在33V左右。如果第一(yi)(yi)次(ci)斷電(dian)(dian)以(yi)后(hou)，電(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)壓(ya)還會(hui)(hui)慢慢回(hui)復到(dao)可以(yi)供電(dian)(dian)，此時，千萬(wan)不(bu)要再用(yong)電(dian)(dian)池(chi)(chi)(chi)里(li)的(de)(de)電(dian)(dian)量，否則會(hui)(hui)使電(dian)(dian)池(chi)(chi)(chi)過放(fang)電(dian)(dian)的(de)(de)，將比(bi)較嚴重(zhong)點影響電(dian)(dian)池(chi)(chi)(chi)的(de)(de)壽(shou)(shou)命。盡充(chong)就(jiu)是(shi)(shi)充(chong)滿(man)電(dian)(dian)，更簡(jian)單了(le)。

5.影響電(dian)池(chi)(chi)充電(dian)效果和壽命(ming)的(de)(de)因素太多(duo)(duo)了，比較明(ming)顯的(de)(de)如(ru)溫度等，關鍵還(huan)有電(dian)動(dong)車使用方法。好(hao)多(duo)(duo)電(dian)動(dong)車的(de)(de)說明(ming)書好(hao)像全(quan)部是笑話(hua)，比如(ru)“逆(ni)風、上坡條(tiao)件要助力(li)(li)，最(zui)(zui)好(hao)不要用電(dian)”“不要帶人(ren)”……，其實(shi)大家也要注意，目前(qian)的(de)(de)電(dian)動(dong)車技(ji)術上，電(dian)池(chi)(chi)提供(gong)的(de)(de)最(zui)(zui)后效果，應該是助力(li)(li)為主，如(ru)果強行啟動(dong)使用以及(ji)帶人(ren)，恐怕耗電(dian)情(qing)(qing)況或者說對(dui)電(dian)池(chi)(chi)的(de)(de)損(sun)傷情(qing)(qing)況，不僅(jin)是1倍數(shu)的(de)(de)關系(xi)。方便的(de)(de)話(hua)，建(jian)議(yi)大家多(duo)(duo)助助力(li)(li)。

6.不同蓄電池廠(chang)家關于充(chong)電方法的(de)說(shuo)明(ming)略有不同，本辦(ban)法僅供參考。

7 、第一次使用電動車前必須充滿12個小時以上外，平時一般電量較為充裕時充2-3個小時就可以了，如果電量較少也就6-7個小時。 
8、電(dian)動車的主要(yao)部(bu)件是(shi)電(dian)池，成本(ben)最(zui)高的也(ye)是(shi)電(dian)池，而(er)目前損(sun)耗最(zui)快的還(huan)是(shi)電(dian)池。目前，電(dian)動車的電(dian)池都是(shi)鉛(qian)酸電(dian)池。過(guo)充會(hui)加(jia)大電(dian)池的水損(sun)失，加(jia)速板柵腐蝕(shi)，活性物質(zhi)軟化，增加(jia)電(dian)池變形的幾率，最(zui)終造成對電(dian)池的致命傷害。 

 
9、如果使(shi)用得當，普通電(dian)池(chi)使(shi)用2年左右問題不(bu)大(da)，反之，使(shi)用壽命大(da)大(da)減短，使(shi)用半(ban)年時間(jian)就不(bu)得不(bu)調換新(xin)電(dian)池(chi)的情(qing)況。而現在電(dian)動車電(dian)池(chi)價格高達500元(yuan)左右，少的也要300元(yuan)左右。 

 
正(zheng)確(que)使用延長電(dian)池壽命(ming) 

 
1.在電動(dong)(dong)車上橋、爬坡或(huo)在頂(ding)風行駛時，應該(gai)輔以人力驅動(dong)(dong)，防(fang)止電池供電電流陡(dou)然增大(da)。 

 
2.在剛上車(che)騎(qi)行(xing)或(huo)行(xing)駛途中(zhong)緊急剎車(che)止(zhi)速(su)后又要騎(qi)行(xing)時(shi)，最好用腳蹬幾下(xia)(xia)，等(deng)電動(dong)車(che)有一定的車(che)速(su)后再加以電動(dong)騎(qi)行(xing)。盡量不要使電動(dong)車(che)在靜止(zhi)狀態下(xia)(xia)直(zhi)接使用電力啟(qi)動(dong)。 

 
3.在騎行中(zhong)，若需加(jia)速時，應緩(huan)慢旋轉調速把，避免直接加(jia)速至最快檔。因為這樣不(bu)僅不(bu)會立即提(ti)高車速，而且(qie)還會產生沖擊電流造成對電池的傷害。在路(lu)況允許的條件下，盡可(ke)能使(shi)電動(dong)車以最高時速行駛(shi)。 

 
4.在騎(qi)行中(zhong)，盡量避免(mian)頻繁剎車、啟動，在道路擁擠時(shi)多用腳蹬(deng)驅動。這樣(yang)(yang)不僅增加了(le)“續行里程(cheng)”，提高(gao)了(le)電池使用效率，同樣(yang)(yang)也延長了(le)電池的使用壽命(ming)。 

 
5.經(jing)常充(chong)電，使電池經(jing)常處(chu)于充(chong)滿(man)狀態，有條件的要做到(dao)隨用隨充(chong)，但要把握好充(chong)電時(shi)間總量(liang)。 

 
6.準(zhun)備(bei)長(chang)期不用的，應將電池充滿后存放，并定期補電(1個月)。 

 
7.電(dian)量(liang)顯示電(dian)池已沒電(dian)了，一(yi)段時間后發現電(dian)池又有小量(liang)電(dian)壓，稱為“回(hui)升(sheng)電(dian)壓”。不要使用這“回(hui)升(sheng)電(dian)壓”來行駛。 

 
、電池為什么(me)在初次使用前要進行補充充電？ 

答：電(dian)池(chi)(chi)從(cong)出廠到使(shi)用，一般要經過 1-2 個月，甚至(zhi)更(geng)長的(de)時間，電(dian)池(chi)(chi)在存(cun)放(fang)期間由于電(dian)池(chi)(chi)內部的(de)自(zi)放(fang)電(dian)等自(zi)發反應，消耗(hao)了一部分電(dian)量，達不到額定(ding)容量值，所以(yi)初(chu)次使(shi)用前，最(zui)好進行補充充電(dian)，以(yi)免顧客誤認為是(shi)容量不足。

2、電(dian)動車如(ru)果要存(cun)放較長時間(jian)應該怎樣(yang)對(dui)電(dian)池進行(xing)處理？ 

答：首先應將電(dian)池充足電(dian)存(cun)放，并(bing)且應該一個月內(nei)至(zhi)少充一次電(dian)，防(fang)(fang)止虧電(dian)，能有效防(fang)(fang)止晶技生成(cheng)造成(cheng)不(bu)可逆鹽化(hua)和晶枝短(duan)路等。

3、電池充電前要不要先放完電？ 

答：鉛(qian)酸(suan)蓄(xu)電(dian)池不同于其它(ta)二(er)次(ci)電(dian)池，它(ta)無記憶效應(ying)，所(suo)以，無論電(dian)池處于何種(zhong)荷(he)電(dian)狀態，都可直接(jie)進行充電(dian)，無須放電(dian)。

4、電池是(shi)勤(qin)充電好(hao)還是(shi)放完電再充電好(hao)？ 

答：由于放電越淺，其循環次數將大幅度增加。因此，按這一理論，勤充電對循環壽命是有益的，但就目前市場上大量流通使用的充電器來講，由于受價格因素及技術水平等影響，充電器存在故障率高，可靠性差，精度低等缺陷。因此，有時勤充電反而影響電池的使用壽命。將電池放空再充電，充電次數雖然減少，但放電時由于單體電池之間總會存在差異可能造成某些單格過放電，過放電池充電接受能力會大大降低，引起充電不足的故障，另外由于放完電再充電，充電器重負荷時間長，易損壞充電器。因此，綜(zong)合上述，我們認(ren)為蓄電(dian)池(chi)放出電(dian)量的(de) 50-70% 時進行一次充電(dian)是(shi)較合理的(de)，對電(dian)池(chi)的(de)使(shi)用有好處。

5、過充(chong)(chong)電(dian)和(he)欠充(chong)(chong)電(dian)有什么害處(chu)？ 

答(da)：過(guo)充電(dian)即蓄電(dian)池(chi)充電(dian)電(dian)流(liu)大于(yu)蓄電(dian)池(chi)可接受電(dian)流(liu)，多出部分即是過(guo)充電(dian)量(liang)(liang)，過(guo)充電(dian)主要是產生電(dian)解水(shui)的副反應，由于(yu)電(dian)池(chi)正(zheng)極產生氧氣轉移到負(fu)極發生氧復合反應，會(hui)發生熱(re)量(liang)(liang)，因此過(guo)充電(dian)量(liang)(liang)實際轉換(huan)成熱(re)量(liang)(liang)使電(dian)池(chi)溫度升高，若不加(jia)以控(kong)制，會(hui)造(zao)成大量(liang)(liang)失水(shui)，嚴重者造(zao)成 “ 熱(re)失控(kong) ” 容量(liang)(liang)劇減，甚(shen)至變形等(deng)故障。欠充電(dian)通(tong)(tong)俗講就是未(wei)充飽電(dian)經常處于(yu)充電(dian)不足(zu)的情(qing)況下，極極就會(hui)逐(zhu)漸(jian)形成一種粗大堅硬的硫(liu)酸鉛，它幾乎不溶解，即產生所謂(wei)的 “ 不可逆硫(liu)酸鹽化 ” ，使用普通(tong)(tong)的方法(fa)(fa)無法(fa)(fa)充進電(dian)，因此容量(liang)(liang)會(hui)一次一次地快速衰減。

6、過放電對電池有什么(me)害處(chu)？ 

電(dian)(dian)(dian)池(chi)在放(fang)電(dian)(dian)(dian)過程中正(zheng)極(ji)活(huo)(huo)性(xing)物質(zhi)(zhi)，負極(ji)活(huo)(huo)性(xing)物質(zhi)(zhi)均逐漸(jian)轉化(hua)成電(dian)(dian)(dian)阻很大(da)(da)(da) PBSO4 ，并消耗電(dian)(dian)(dian)解(jie)液中的(de)硫酸(suan)(suan)，內阻逐漸(jian)增(zeng)大(da)(da)(da)，因此(ci)過放(fang)電(dian)(dian)(dian)時，特別是以較大(da)(da)(da)電(dian)(dian)(dian)流(liu)過放(fang)電(dian)(dian)(dian)會發出大(da)(da)(da)量(liang)熱(re)量(liang)，并且電(dian)(dian)(dian)池(chi)的(de)硫酸(suan)(suan)量(liang)很少，過放(fang)電(dian)(dian)(dian)時硫酸(suan)(suan)濃度減得很低(di)， PBSO4 溶解(jie)度大(da)(da)(da)幅度增(zeng)加，因此(ci)容易在極(ji)板上形成一種粗大(da)(da)(da)堅硬的(de) PBSO4 晶體，即 “ 不可逆硫酸(suan)(suan)鹽化(hua) ” 大(da)(da)(da)大(da)(da)(da)地減弱電(dian)(dian)(dian)池(chi)的(de)充電(dian)(dian)(dian)接(jie)受能力，危害特別大(da)(da)(da)。

7、電動(dong)車(che)電池什么(me)情況下(xia)需進(jin)行維護(hu)充(chong)電，其(qi)充(chong)電參數怎樣，怎樣進(jin)行維護(hu)充(chong)電？ 

答(da)：電(dian)(dian)(dian)(dian)(dian)動車電(dian)(dian)(dian)(dian)(dian)池(chi)遇下列情況之一時需要進(jin)行(xing)維護充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)： 1 、電(dian)(dian)(dian)(dian)(dian)池(chi)容量(liang)衰減(jian)減(jian)速太快； 2 、出現落(luo)后(hou)(hou)(hou)(hou)電(dian)(dian)(dian)(dian)(dian)池(chi)； 3 、電(dian)(dian)(dian)(dian)(dian)池(chi)失液后(hou)(hou)(hou)(hou)，重(zhong)新補液； 4 、電(dian)(dian)(dian)(dian)(dian)池(chi)長(chang)時間(jian)放(fang)置后(hou)(hou)(hou)(hou)； 5 、電(dian)(dian)(dian)(dian)(dian)池(chi)出現嚴重(zhong)過放(fang)電(dian)(dian)(dian)(dian)(dian)后(hou)(hou)(hou)(hou)； 6 、電(dian)(dian)(dian)(dian)(dian)池(chi)長(chang)時間(jian)處(chu)于低溫(wen)環境(jing)工作等(deng)； 7 、充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)參數(shu)(shu)不合理長(chang)期欠(qian)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)；維護充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)參數(shu)(shu)怎(zen)樣定；一般采用(yong)恒壓(ya)限流充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)或多階段(duan)恒流充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)前中期與(yu)車配(pei)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)參數(shu)(shu)基本一致(zhi)，只是充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)后(hou)(hou)(hou)(hou)期將(jiang)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)最高(gao)電(dian)(dian)(dian)(dian)(dian)壓(ya)提高(gao)到更高(gao)。即采用(yong)WD充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，進(jin)行(xing)深度充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)修復(fu)已落(luo)后(hou)(hou)(hou)(hou)電(dian)(dian)(dian)(dian)(dian)池(chi)。維護充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)也叫均衡充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。

8、電池初始容量(liang)大小與壽命有什(shen)么關系？ 

答：電池(chi)容(rong)量(liang)(liang)(liang)受(shou)活性(xing)(xing)物(wu)(wu)質和利用(yong)(yong)率(lv)(lv)影響(xiang)。電動助力車蓄電池(chi)外形尺寸(cun)一(yi)(yi)定(ding)，極(ji)板的(de)質量(liang)(liang)(liang)已被(bei)限制(zhi)到一(yi)(yi)定(ding)的(de)程度，只有提高活性(xing)(xing)物(wu)(wu)質的(de)利用(yong)(yong)率(lv)(lv)，才(cai)能提高容(rong)量(liang)(liang)(liang)。要提高電池(chi)容(rong)量(liang)(liang)(liang)，必然(ran)增加(jia)孔率(lv)(lv)，提高 PbO2 含量(liang)(liang)(liang)、硫酸比重，但是(shi)這些措施(shi)都會加(jia)速(su)正(zheng)極(ji)板的(de)軟(ruan)化(hua)，造成電池(chi)壽命(ming)加(jia)速(su)衰減，充放電過(guo)程中(zhong)活性(xing)(xing)物(wu)(wu)質會產生膨(peng)脹、收縮 ( 特別是(shi)正(zheng)極(ji)板 ) ，放電深(shen)度越(yue)深(shen)，活性(xing)(xing)物(wu)(wu)質膨(peng)脹收縮量(liang)(liang)(liang)越(yue)大，更加(jia)速(su)活性(xing)(xing)物(wu)(wu)質軟(ruan)化(hua)。因此，初始(shi)容(rong)量(liang)(liang)(liang)偏大時直接影響(xiang)蓄電池(chi)充放電次(ci)數。當然(ran)要滿足使用(yong)(yong)，要求(qiu)(qiu)初始(shi)容(rong)量(liang)(liang)(liang)不能太小，需(xu)要一(yi)(yi)種折中(zhong)的(de)選擇才(cai)能滿足需(xu)要，既保證延長壽命(ming)，又(you)確(que)保容(rong)量(liang)(liang)(liang)滿足使用(yong)(yong)要求(qiu)(qiu)。

9、電(dian)池電(dian)壓高容量(liang)就大嗎？ 

答：電(dian)(dian)池(chi)電(dian)(dian)壓與(yu)容(rong)量(liang)是兩個(ge)概念，電(dian)(dian)壓與(yu)電(dian)(dian)極材料和電(dian)(dian)解液濃度相關，電(dian)(dian)池(chi)的容(rong)量(liang)是活性物質經電(dian)(dian)化學(xue)反應產(chan)生電(dian)(dian)流而釋放出來(lai)的，它(ta)與(yu)各(ge)活性物質的量(liang)，反應條件及利用率，連(lian)接等有關，因此電(dian)(dian)壓高不能(neng)說容(rong)量(liang)就高，電(dian)(dian)壓低(di)也不一定容(rong)量(liang)就低(di)。

10、溫度對(dui)電(dian)池性能有(you)什么影響(xiang)？ 

答(da)：電(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)電(dian)(dian)(dian)(dian)、放(fang)電(dian)(dian)(dian)(dian)時(shi)，在電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)極上(shang)發生電(dian)(dian)(dian)(dian)化(hua)學(xue)反應，溫(wen)(wen)(wen)度(du)越(yue)(yue)(yue)高(gao)，電(dian)(dian)(dian)(dian)池(chi)各活(huo)性物質(zhi)的(de)活(huo)度(du)增加，電(dian)(dian)(dian)(dian)解液粘度(du)降(jiang)低(di)，電(dian)(dian)(dian)(dian)阻(zu)減小，因此電(dian)(dian)(dian)(dian)化(hua)學(xue)反應容(rong)易進行，反之則不容(rong)易進行。放(fang)電(dian)(dian)(dian)(dian)時(shi)溫(wen)(wen)(wen)度(du)越(yue)(yue)(yue)低(di)，放(fang)出容(rong)量(liang)越(yue)(yue)(yue)低(di)，在特別低(di)的(de)溫(wen)(wen)(wen)度(du)下(xia)，放(fang)出容(rong)量(liang)將大幅度(du)下(xia)降(jiang)，溫(wen)(wen)(wen)度(du)高(gao)則相反；充(chong)電(dian)(dian)(dian)(dian)時(shi)溫(wen)(wen)(wen)度(du)越(yue)(yue)(yue)低(di)，充(chong)電(dian)(dian)(dian)(dian)接受能(neng)力(li)(li)越(yue)(yue)(yue)差，要求充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓較高(gao)，才能(neng)充(chong)足電(dian)(dian)(dian)(dian)。反之溫(wen)(wen)(wen)度(du)越(yue)(yue)(yue)高(gao)，充(chong)電(dian)(dian)(dian)(dian)接受能(neng)力(li)(li)越(yue)(yue)(yue)好，易造成過充(chong)電(dian)(dian)(dian)(dian)，因此要求降(jiang)低(di)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓，才不至于(yu)造成過充(chong)電(dian)(dian)(dian)(dian)。此溫(wen)(wen)(wen)度(du)的(de)變化(hua)，直接影響電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)和放(fang)電(dian)(dian)(dian)(dian)性能(neng)。

11、電(dian)動車(che)電(dian)池循環次數是(shi)一(yi)定的嗎？ 

答：循環次數，根據放電深度不同而差別很大，放電深度越深，循環次數越小，放電深度越淺，循環次數越多，有時是呈指數變化，根據試驗結果放電深渡與循環次數聯系如下表： 
放(fang)電深度100% 70% 50% 20% 10% 循環次數350 次 550 次 1000 次 2800 次 7000 次
