查看產品是否有變(bian)形、裂(lie)紋(wen)、劃(hua)痕及(ji)漏液痕跡，電(dian)池接線(xian)端子(zi)上(shang)應干凈，無銹蝕(shi)，標志(zhi)應清晰。好的(de)(de)電(dian)動(dong)車蓄(xu)電(dian)池外(wai)(wai)殼(ke)很厚實，接線(xian)端子(zi)粗(cu)大，而且電(dian)池上(shang)印字也清晰。另外(wai)(wai)，要(yao)仔細辨(bian)認(ren)找(zhao)準正品的(de)(de)。

電池(chi)(chi)標注(zhu)的額(e)定(ding)容(rong)量越大，電池(chi)(chi)放電時間越長。最好不要購買無(wu)額(e)定(ding)標注(zhu)的電池(chi)(chi)，要注(zhu)意是否為電動(dong)車(che)專(zhuan)用。如(ru)有多個容(rong)量標注(zhu)，應以額(e)定(ding)容(rong)量為準(zhun)。另外，選購與(yu)電池(chi)(chi)配套的、帶自(zi)動(dong)控(kong)制的智能型充(chong)電器。

用(yong)電(dian)(dian)池(chi)檢測設備(bei)檢測單體電(dian)(dian)池(chi)容量和性(xing)能。性(xing)能優良(liang)的(de)(de)電(dian)(dian)動車蓄(xu)電(dian)(dian)池(chi)內阻小(xiao)(xiao)，單體電(dian)(dian)壓(ya)誤差也小(xiao)(xiao)。大電(dian)(dian)流(liu)放電(dian)(dian)時(shi)，電(dian)(dian)壓(ya)降的(de)(de)越(yue)小(xiao)(xiao)越(yue)好(hao)。電(dian)(dian)池(chi)充電(dian)(dian)進入飽和后(hou)和蓄(xu)電(dian)(dian)池(chi)的(de)(de)電(dian)(dian)壓(ya)應(ying)是一(yi)致的(de)(de)，誤差以小(xiao)(xiao)于0.05伏為最好(hao)。

盡量(liang)選購知名(ming)企業(ye)、大(da)型企業(ye)的(de)品牌(pai)(pai)電(dian)(dian)池有保(bao)證。大(da)品牌(pai)(pai)的(de)電(dian)(dian)動車(che)電(dian)(dian)池信譽有保(bao)障(zhang)，質(zhi)量(liang)也(ye)過關，而且大(da)品牌(pai)(pai)售后服務也(ye)到位(wei)，看下(xia)是(shi)否有400電(dian)(dian)話。當(dang)然小廠家也(ye)有好產品，但是(shi)也(ye)得找個可靠品牌(pai)(pai)。
