电动叉车电池如果过度充电会导致大量的气体冲刷电池的极板，而这样的行为会导致活性物质脱落，终缩减电池的使用寿命。另外，电动叉车电池过度充电还会导致失水速度加快，影响电解液的分解，导致电瓶温度升高，甚至是自燃，这一点非常重要。据调查数据显示，有百分之二十左右的杂牌电动车电池，会在使用一段时间之后自燃，尤其是高温天气下过度充电更是如此，有的虽然只是外壳变形，但是也存在极大的安全隐患。
if the electric forklift battery is overcharged, a large amount of gas will wash the battery plate, and this behavior will lead to the loss of active substances, ultimately reducing the battery life. in addition, electric forklift battery overcharge will also lead to faster loss of water speed, affect the decomposition of electrolyte, lead to battery temperature rise, even spontaneous combustion, this is very important. according to the survey data, about 20% of the hybrid electric vehicle batteries will spontaneously ignite after a period of use, especially in hot weather, overcharging is even more so, although some are only shell deformation, but there are also great safety risks.
不仅如此，过度放电也会导致电瓶极板软化，终缩短使用寿命。那么，面对这样的情况，电动叉车用户该如何保养电池呢？保养电池的方法有很多，其中比较常见的有以下几种：
not only that, excessive discharge will also lead to softening of the battery plate, and ultimately shorten the service life. so, in the face of such a situation, how can the electric forklift users maintain the battery? there are many ways to maintain batteries.
1.在上坡、逆风行驶的时候，好借助脚助力
1. when uphill and against the wind, it is better to use foot assistance.
不少人在行驶过程中完全依靠电动叉车，尤其是上坡、逆风行驶，会采用加速的方式，这样做不仅会加速电池电量的损耗，同时也会对电池造成一定的损害。
many people rely entirely on electric forklift trucks in the course of driving, especially uphill, against the wind, will adopt acceleration mode, which will not only accelerate the loss of battery power, but also cause certain damage to the battery.
2.不经常放完电后行驶，低于百分之三十的时候就要充电
2. do not always drive after the electricity is completed, less than thirty percent will be charged.
电池过度充电对电池不好，但是如果过度放电再充电也是有危害的。后，对于长期搁置的电池，建议不要立即使用，好先充满电之后再用，这样可以保护电池不受损害。
battery overcharging is bad for batteries, but excessive discharge and recharging are also harmful. finally, for long-term shelved batteries, it is recommended not to use immediately, it is best to first charge and then use, this can protect the battery from damage.
