  首先检测(ce)(ce)火(huo)炬(ju)(ju)(ju)蓄(xu)(xu)电(dian)(dian)(dian)(dian)池(chi)内(nei)部(bu)是否亏电(dian)(dian)(dian)(dian)。正(zheng)常火(huo)炬(ju)(ju)(ju)蓄(xu)(xu)电(dian)(dian)(dian)(dian)池(chi)充(chong)足电(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)应在12V以(yi)上(shang),电(dian)(dian)(dian)(dian)解液(ye)密(mi)度为1.26~1.28g/cm,且液(ye)面高度应在标准(zhun)范围。采(cai)用火(huo)炬(ju)(ju)(ju)蓄(xu)(xu)电(dian)(dian)(dian)(dian)池(chi)放(fang)电(dian)(dian)(dian)(dian)测(ce)(ce)试(shi)(shi)仪(yi),把测(ce)(ce)试(shi)(shi)仪(yi)正(zheng)负钳分(fen)别夹持火(huo)炬(ju)(ju)(ju)蓄(xu)(xu)电(dian)(dian)(dian)(dian)池(chi)正(zheng)负电(dian)(dian)(dian)(dian)极,按下测(ce)(ce)试(shi)(shi)按钮,12V电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)持续放(fang)电(dian)(dian)(dian)(dian)3~5s后,观察(cha)测(ce)(ce)试(shi)(shi)仪(yi)表电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)指示(shi)情况。如果(guo)(guo)(guo)仪(yi)表指示(shi)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)9.6V以(yi)上(shang),说(shuo)明火(huo)炬(ju)(ju)(ju)蓄(xu)(xu)电(dian)(dian)(dian)(dian)池(chi)状态良好,但(dan)电(dian)(dian)(dian)(dian)量不足;若稳定在10.6~11.6V,说(shuo)明火(huo)炬(ju)(ju)(ju)蓄(xu)(xu)电(dian)(dian)(dian)(dian)池(chi)电(dian)(dian)(dian)(dian)量充(chong)足;如果(guo)(guo)(guo)低(di)于(yu)(yu)9.6V但(dan)是电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)处(chu)于(yu)(yu)某(mou)个数值(zhi)不动,说(shuo)明火(huo)炬(ju)(ju)(ju)蓄(xu)(xu)电(dian)(dian)(dian)(dian)池(chi)处(chu)于(yu)(yu)严重亏电(dian)(dian)(dian)(dian)状态,需要补充(chong)充(chong)电(dian)(dian)(dian)(dian);如果(guo)(guo)(guo)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)慢慢下降,说(shuo)明火(huo)炬(ju)(ju)(ju)蓄(xu)(xu)电(dian)(dian)(dian)(dian)池(chi)内(nei)部(bu)有(you)短路现象;如果(guo)(guo)(guo)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)快速下降为0V,说(shuo)明火(huo)炬(ju)(ju)(ju)蓄(xu)(xu)电(dian)(dian)(dian)(dian)池(chi)内(nei)部(bu)有(you)断路。
