铅蓄电池具有电动势高、放电电压平稳、内电阻小、造价低和比较适应汽车起动时大电流放电的需要,所以目前在汽车上得到广泛的运用。但是,这种蓄电池有寿命短、不耐震、电极活性物质易脱落、比能量低(一般在40瓦时/公斤左右)、生产过程有毒等缺点。在合理使用铅蓄电池的情况下,国产铅蓄电池的使用寿命一般在二年左右,但由于我们对蓄电池的电解液比重调整不当,充电电压调正不当、保养清洁不当、放电次数频繁、放电时间过长、放电电流过大等各种因素,造成铅蓄电池的使用寿命一般只在5～7个月左右。
Lead-acid batteries with high electromotive force, discharge voltage stability, small internal resistance, low cost and more suitable for starting the car when the need for large current discharge, it is now widely used in the car. However, this battery has a short life, no shock, the electrode active material is easy to fall off, low energy (typically 40 watts / kg), the production process is toxic and other shortcomings. In the case of the rational use of lead-acid batteries, domestic lead-acid batteries are generally two years life, but due to our improper adjustment of the proportion of the battery electrolyte, improper charging voltage adjustment, maintenance improper cleaning, frequent discharges, discharge time Long, large discharge current and other factors, resulting in the life of lead-acid batteries generally only 5 to 7 months or so.
