測(ce)(ce)量(liang)電瓶電量(liang)可以(yi)使(shi)用(yong)電壓表、電瓶測(ce)(ce)試儀、車(che)載電腦等(deng)工具，也(ye)可以(yi)觀察電量(liang)指示器、啟動(dong)車(che)輛測(ce)(ce)試等(deng)。

使用電(dian)(dian)(dian)(dian)(dian)壓(ya)表測量時，先將(jiang)紅色測試筆連(lian)電(dian)(dian)(dian)(dian)(dian)瓶正(zheng)極，黑色連(lian)負(fu)極，關閉汽車所(suo)有(you)電(dian)(dian)(dian)(dian)(dian)器設備且發(fa)動機停轉，打(da)(da)開電(dian)(dian)(dian)(dian)(dian)壓(ya)表設為“DCV”模式，進(jin)行(xing)“開路(lu)電(dian)(dian)(dian)(dian)(dian)壓(ya)測試”，電(dian)(dian)(dian)(dian)(dian)壓(ya)在(zai)12.5V至(zhi)12.6V間電(dian)(dian)(dian)(dian)(dian)瓶電(dian)(dian)(dian)(dian)(dian)量正(zheng)常，低于12.5V電(dian)(dian)(dian)(dian)(dian)量不(bu)(bu)足；再啟動發(fa)動機進(jin)行(xing)“負(fu)載(zai)電(dian)(dian)(dian)(dian)(dian)壓(ya)測試”，電(dian)(dian)(dian)(dian)(dian)壓(ya)在(zai)13.7V至(zhi)14.7V間充電(dian)(dian)(dian)(dian)(dian)正(zheng)常，高(gao)于14.7V充電(dian)(dian)(dian)(dian)(dian)過度，低于13.7V充電(dian)(dian)(dian)(dian)(dian)不(bu)(bu)足。電(dian)(dian)(dian)(dian)(dian)瓶測試儀需連(lian)接到電(dian)(dian)(dian)(dian)(dian)瓶并(bing)打(da)(da)開電(dian)(dian)(dian)(dian)(dian)源開關，按操作(zuo)說明(ming)操作(zuo)，電(dian)(dian)(dian)(dian)(dian)量80%以(yi)上正(zheng)常，低于80%需充電(dian)(dian)(dian)(dian)(dian)或換電(dian)(dian)(dian)(dian)(dian)瓶。部分高(gao)端車型可打(da)(da)開車輛電(dian)(dian)(dian)(dian)(dian)腦(nao)系統查看電(dian)(dian)(dian)(dian)(dian)瓶電(dian)(dian)(dian)(dian)(dian)量顯面，同樣(yang)電(dian)(dian)(dian)(dian)(dian)量80%以(yi)上正(zheng)常，低于80%需關注。

此外，部分電(dian)(dian)瓶(ping)上帶(dai)有電(dian)(dian)量指示器(qi)，通過不(bu)同(tong)顏色或標記來(lai)表示電(dian)(dian)量狀態。還可以(yi)嘗(chang)試(shi)啟動(dong)車輛(liang)(liang)，如果啟動(dong)困難或啟動(dong)后燈光不(bu)穩定，可能(neng)是電(dian)(dian)瓶(ping)電(dian)(dian)量不(bu)足。不(bu)同(tong)方(fang)法各有優劣，車主可根據實際情況選擇合(he)適(shi)方(fang)式，及時掌(zhang)握(wo)電(dian)(dian)量能(neng)保障車輛(liang)(liang)正常運行。
