美国邱健Trojan蓄电池L16PG-AC电动雪橇6V420AH电动起子
Colloidal lead-acid batteries and ordinary lead-acid batteries havethe same performance, except that the electrolyte inside thebattery is in a semi solidified latex state and a liquid state.Ordinary lead-acid batteries in a liquid state require periodicmaintenance with distilled water during use, while colloidallead-acid batteries do not require maintenance with distilled water(commonly referred to as maintenance free). 
静止电动势是指铅酸蓄电池处于静止状态(不充电也不放电),单格电池正､负极之间的电位差,其大小取决于电解液的相对密度和温度｡一般静止电动势Ej可用以下经验公式表示:
Ej=0.85+γ25℃
式中,Ej为静止电动势(V);γ25℃为25℃时电解液的相对密度｡
