查(cha)看產品(pin)是否(fou)有變形、裂紋、劃痕(hen)及漏(lou)液痕(hen)跡，電(dian)池(chi)(chi)接(jie)線(xian)(xian)端子上(shang)應(ying)干凈，無(wu)銹蝕，標志應(ying)清晰。好的電(dian)動車(che)蓄電(dian)池(chi)(chi)外殼很厚實，接(jie)線(xian)(xian)端子粗大(da)，而且(qie)電(dian)池(chi)(chi)上(shang)印字也清晰。另外，要仔細辨認找(zhao)準正(zheng)品(pin)的。

電池(chi)(chi)標注(zhu)的(de)額(e)定(ding)(ding)容(rong)量越大(da)，電池(chi)(chi)放電時間(jian)越長。最好(hao)不(bu)要購買無額(e)定(ding)(ding)標注(zhu)的(de)電池(chi)(chi)，要注(zhu)意(yi)是否(fou)為電動(dong)車(che)專用。如有多個容(rong)量標注(zhu)，應以額(e)定(ding)(ding)容(rong)量為準。另外，選購與(yu)電池(chi)(chi)配套(tao)的(de)、帶自動(dong)控制的(de)智能型充(chong)電器。

用電(dian)(dian)(dian)池(chi)(chi)檢(jian)測(ce)設備(bei)檢(jian)測(ce)單(dan)體電(dian)(dian)(dian)池(chi)(chi)容(rong)量(liang)和(he)性(xing)能。性(xing)能優良的(de)電(dian)(dian)(dian)動車蓄(xu)電(dian)(dian)(dian)池(chi)(chi)內阻小，單(dan)體電(dian)(dian)(dian)壓誤差也小。大電(dian)(dian)(dian)流放電(dian)(dian)(dian)時，電(dian)(dian)(dian)壓降(jiang)的(de)越(yue)小越(yue)好。電(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)進入飽和(he)后和(he)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)壓應是一致的(de)，誤差以(yi)小于0.05伏為最(zui)好。

盡(jin)量選購知名(ming)企業(ye)、大(da)(da)型企業(ye)的(de)品(pin)(pin)牌電池有(you)保證(zheng)。大(da)(da)品(pin)(pin)牌的(de)電動車電池信譽有(you)保障(zhang)，質量也(ye)(ye)過關，而且大(da)(da)品(pin)(pin)牌售后服務也(ye)(ye)到位，看下是否(fou)有(you)400電話。當然(ran)小廠家也(ye)(ye)有(you)好產品(pin)(pin)，但是也(ye)(ye)得(de)找個可靠品(pin)(pin)牌。
