免维护铅蓄电池的使用特性优点
（１）http://img.miaomudu.com/2020/12/2020092745493使用中不需要加水
普通蓄电池在接近完全充电时，由于过充电而造http://img.miaomudu.com/2020/12/2020092745493成水http://img.miaomudu.com/2020/12/2020092745493的分http://img.miaomudu.com/2020/12/2020092745493解，会http://img.miaomudu.com/2020/12/2020092745493析出http://img.miaomudu.com/2020/12/2020092745493氢气http://img.miaomudu.com/2020/12/2020092745493和氧气，使http://img.miaomudu.com/2020/12/2020092745493电解http://img.miaomudu.com/2020/12/2020092745493液液面降低，而且充电终了的充电速率越大，耗水量就http://img.miaomudu.com/2020/12/2020092745493越多。http://img.miaomudu.com/2020/12/2020092745493免http://img.miaomudu.com/2020/12/2020092745493维护蓄http://img.miaomudu.com/2020/12/2020092745493电池http://img.miaomudu.com/2020/12/2020092745493与普http://img.miaomudu.com/2020/12/2020092745493通蓄电池相http://img.miaomudu.com/2020/12/2020092745493比较，在同时使用http://img.miaomudu.com/2020/12/2020092745493１８http://img.miaomudu.com/2020/12/2020092745493个月后，前者的过充电http://img.miaomudu.com/2020/12/2020092745493电流http://img.miaomudu.com/2020/12/2020092745493为http://img.miaomudu.com/2020/12/2020092745493５２http://img.miaomudu.com/2020/12/2020092745493ｍhttp://img.miaomudu.com/2020/12/2020092745493Ａ，而后http://img.miaomudu.com/2020/12/2020092745493者达http://img.miaomudu.com/2020/12/2020092745493１１０http://img.miaomudu.com/2020/12/2020092745493ｍhttp://img.miaomudu.com/2020/12/2020092745493Ａhttp://img.miaomudu.com/2020/12/2020092745493；而且http://img.miaomudu.com/2020/12/2020092745493前者充http://img.miaomudu.com/2020/12/2020092745493电电http://img.miaomudu.com/2020/12/2020092745493流仅http://img.miaomudu.com/2020/12/2020092745493为后者的http://img.miaomudu.com/2020/12/2020092745493１http://img.miaomudu.com/2020/12/2020092745493／２０，因而析气量减少了http://img.miaomudu.com/2020/12/2020092745493９５％http://img.miaomudu.com/2020/12/2020092745493，耗水量也大大减少。此外，由于免维护蓄电池采用袋式隔板将极板完全包住，并且极板都是直接安放在蓄电池的底板上。http://img.miaomudu.com/2020/12/2020092745493这样，不仅储液量增加，而且耗水量也大大减少，因http://img.miaomudu.com/2020/12/2020092745493此免http://img.miaomudu.com/2020/12/2020092745493维护蓄电池http://img.miaomudu.com/2020/12/2020092745493在使用http://img.miaomudu.com/2020/12/2020092745493中不http://img.miaomudu.com/2020/12/2020092745493需要http://img.miaomudu.com/2020/12/2020092745493加水。
（２）http://img.miaomudu.com/2020/12/2020092745493自放电少，寿命长
普通蓄电池由于极板栅架采用铅锑合金，在放电http://img.miaomudu.com/2020/12/2020092745493过程http://img.miaomudu.com/2020/12/2020092745493中，锑要从http://img.miaomudu.com/2020/12/2020092745493栅架http://img.miaomudu.com/2020/12/2020092745493内转http://img.miaomudu.com/2020/12/2020092745493移到正、负http://img.miaomudu.com/2020/12/2020092745493极板http://img.miaomudu.com/2020/12/2020092745493的活性物质以及电解液中去，因而增加了自放电，缩短了使用寿命。
正常情况下蓄电池使用寿命为２http://img.miaomudu.com/2020/12/2020092745493年。http://img.miaomudu.com/2020/12/2020092745493
免维护蓄电池极板栅架采用铅http://img.miaomudu.com/2020/12/2020092745493钙合http://img.miaomudu.com/2020/12/2020092745493金，由于板栅中http://img.miaomudu.com/2020/12/2020092745493没有锑，使http://img.miaomudu.com/2020/12/2020092745493自放http://img.miaomudu.com/2020/12/2020092745493电大http://img.miaomudu.com/2020/12/2020092745493为减http://img.miaomudu.com/2020/12/2020092745493少，延长http://img.miaomudu.com/2020/12/2020092745493了http://img.miaomudu.com/2020/12/2020092745493使用寿命。
免维护蓄电池的正常使用寿命为http://img.miaomudu.com/2020/12/2020092745493４http://img.miaomudu.com/2020/12/2020092745493年，比普通蓄电池提高一倍。
（３）http://img.miaomudu.com/2020/12/2020092745493接线柱腐蚀较小
普通蓄电池中，由于析出的酸气聚集在蓄电池顶http://img.miaomudu.com/2020/12/2020092745493部，不仅http://img.miaomudu.com/2020/12/2020092745493会腐蚀http://img.miaomudu.com/2020/12/2020092745493接线http://img.miaomudu.com/2020/12/2020092745493柱，还会在http://img.miaomudu.com/2020/12/2020092745493电极http://img.miaomudu.com/2020/12/2020092745493极桩http://img.miaomudu.com/2020/12/2020092745493之间形成短路电流。http://img.miaomudu.com/2020/12/2020092745493免维护蓄电池因为有新型安全通气装置，不仅能将酸气保留在单格电池内部，而且能够预防火花或火焰进入蓄电池；不但可以减少或避免由外部原因引起的蓄电池爆炸，而且能够保持蓄电池盖顶部的干燥，从而减少了接线柱的腐蚀，保证电气线路连接牢固可靠。
（４）http://img.miaomudu.com/2020/12/2020092745493起动性能好
免维护蓄电池由于单格电池之间采用了穿壁式连http://img.miaomudu.com/2020/12/2020092745493接，缩短http://img.miaomudu.com/2020/12/2020092745493了电路http://img.miaomudu.com/2020/12/2020092745493的连http://img.miaomudu.com/2020/12/2020092745493接长度，减小了http://img.miaomudu.com/2020/12/2020092745493内阻，
可以使连接条上的功率损失减少http://img.miaomudu.com/2020/12/2020092745493８０％http://img.miaomudu.com/2020/12/2020092745493，放电电压提http://img.miaomudu.com/2020/12/2020092745493高http://img.miaomudu.com/2020/12/2020092745493０．１５http://img.miaomudu.com/2020/12/2020092745493～http://img.miaomudu.com/2020/12/2020092745493０．４http://img.miaomudu.com/2020/12/2020092745493Ｖhttp://img.miaomudu.com/2020/12/2020092745493。http://img.miaomudu.com/2020/12/2020092745493因此与http://img.miaomudu.com/2020/12/2020092745493普通蓄http://img.miaomudu.com/2020/12/2020092745493电池http://img.miaomudu.com/2020/12/2020092745493相比http://img.miaomudu.com/2020/12/2020092745493具有较好的起动性能。
汽车免维护铅酸蓄电池虽然称之为“免维护”，但也并非完全可以放任不管。
一般建议每3万公里检查一次蓄电池，每8万公里进行一次。正常使用状态下，普通蓄电池2-3年就需要进行更换，并且没有什么可以延长其使用寿命的其他方法。

不仅如此致使蓄电池损坏的原因有很多：http://img.miaomudu.com/2020/12/2020092745493
下面这些情况都会减少免维护铅蓄电池的使用寿命
1：过度放电
2：蓄电池长时间存放（在存放期间没有充过电）
3：不能通过汽车发动机充电
4：没有电解液
5：电解液比重太高
6：在高温条件下充电
7：受污物污染（例如受到盐酸、海水、有机酸等污染）
8：蓄电池充电时加上过大的电流
9：电极板变形造成正极板与包极板互相接触，因而产生短路现象
10：在极板上部及下部沉积有污物，引起短路
