查看產品是(shi)否(fou)有變(bian)形、裂紋、劃(hua)痕及(ji)漏液痕跡，電池接線端(duan)子上應干凈，無銹(xiu)蝕，標志(zhi)應清(qing)晰(xi)。好的電動車(che)蓄電池外殼(ke)很(hen)厚實(shi)，接線端(duan)子粗(cu)大(da)，而且電池上印字也清(qing)晰(xi)。另外，要仔(zi)細辨(bian)認找準正品的。

電(dian)(dian)(dian)(dian)池標(biao)注(zhu)的額定容(rong)量(liang)越大(da)，電(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)時間越長。最好(hao)不要(yao)購(gou)買無額定標(biao)注(zhu)的電(dian)(dian)(dian)(dian)池，要(yao)注(zhu)意是否為(wei)電(dian)(dian)(dian)(dian)動車專用。如有多個容(rong)量(liang)標(biao)注(zhu)，應以額定容(rong)量(liang)為(wei)準。另外，選購(gou)與電(dian)(dian)(dian)(dian)池配套(tao)的、帶自動控制的智(zhi)能型(xing)充電(dian)(dian)(dian)(dian)器。

用電(dian)(dian)池(chi)檢(jian)測設備(bei)檢(jian)測單體電(dian)(dian)池(chi)容量和性(xing)能。性(xing)能優良的(de)電(dian)(dian)動(dong)車蓄(xu)電(dian)(dian)池(chi)內(nei)阻(zu)小(xiao)，單體電(dian)(dian)壓(ya)誤(wu)差也小(xiao)。大電(dian)(dian)流放電(dian)(dian)時，電(dian)(dian)壓(ya)降的(de)越小(xiao)越好。電(dian)(dian)池(chi)充(chong)電(dian)(dian)進(jin)入飽(bao)和后和蓄(xu)電(dian)(dian)池(chi)的(de)電(dian)(dian)壓(ya)應(ying)是(shi)一致的(de)，誤(wu)差以小(xiao)于0.05伏(fu)為最好。

盡量選(xuan)購知名企業(ye)、大型(xing)企業(ye)的(de)品牌電池有保證(zheng)。大品牌的(de)電動(dong)車電池信譽有保障，質量也(ye)過關(guan)，而且大品牌售后服(fu)務也(ye)到位，看下是否有400電話(hua)。當然小(xiao)廠家也(ye)有好產品，但(dan)是也(ye)得找個可(ke)靠品牌。
