查看產品是否有變(bian)形、裂(lie)紋(wen)、劃痕及漏液(ye)痕跡，電池接線(xian)端子(zi)上(shang)應(ying)干凈，無銹蝕(shi)，標志應(ying)清晰(xi)(xi)。好的電動車蓄電池外(wai)殼很厚實(shi)，接線(xian)端子(zi)粗大，而(er)且電池上(shang)印字也清晰(xi)(xi)。另外(wai)，要(yao)仔細辨(bian)認(ren)找準正(zheng)品的。

電(dian)(dian)池(chi)標注(zhu)(zhu)的(de)額定容(rong)(rong)量(liang)越(yue)大(da)，電(dian)(dian)池(chi)放電(dian)(dian)時間越(yue)長。最好(hao)不要購買無(wu)額定標注(zhu)(zhu)的(de)電(dian)(dian)池(chi)，要注(zhu)(zhu)意是(shi)否為電(dian)(dian)動車專(zhuan)用。如有多個容(rong)(rong)量(liang)標注(zhu)(zhu)，應以額定容(rong)(rong)量(liang)為準。另外，選購與電(dian)(dian)池(chi)配(pei)套的(de)、帶自動控制(zhi)的(de)智能型充電(dian)(dian)器(qi)。

用電(dian)(dian)池檢(jian)測(ce)設備檢(jian)測(ce)單體電(dian)(dian)池容量和(he)性能。性能優良的電(dian)(dian)動車蓄(xu)電(dian)(dian)池內阻(zu)小，單體電(dian)(dian)壓誤差也(ye)小。大電(dian)(dian)流放(fang)電(dian)(dian)時，電(dian)(dian)壓降的越小越好(hao)。電(dian)(dian)池充電(dian)(dian)進入飽和(he)后(hou)和(he)蓄(xu)電(dian)(dian)池的電(dian)(dian)壓應是(shi)一(yi)致的，誤差以小于(yu)0.05伏為最好(hao)。

盡量選購(gou)知名企業、大型企業的品(pin)牌(pai)電(dian)(dian)池(chi)(chi)有(you)(you)保(bao)證。大品(pin)牌(pai)的電(dian)(dian)動車(che)電(dian)(dian)池(chi)(chi)信譽有(you)(you)保(bao)障(zhang)，質量也(ye)過關，而且大品(pin)牌(pai)售后服務也(ye)到位(wei)，看下是否有(you)(you)400電(dian)(dian)話(hua)。當然小廠家也(ye)有(you)(you)好產品(pin)，但(dan)是也(ye)得找個可靠品(pin)牌(pai)。
