为何循环寿命长？Why it has good cycle life?

1.双极板结构，电流密度很均匀，充电效率更高(活性物质转化效率更高)；

Bipolar structure which makes the current density is very uniform   and higher charge efficiency;

2.冷挤压成型纯铅复合材料板栅，耐腐蚀性是普通的数倍；

The composite pure lead grid is made by cold extruding process which makes several times corrosion resistance than normal casting technology.

3.水平极板结构，消除了电解液分层现象，有效提升充电接受性能；

Horizontal plates stacking eliminates the electrolyte stratification, which effectively improved the charging efficiency.

4.特殊的循环型配方，提升了循环寿命和过放电恢复性能。

Special cyclic formula integrated, not only increased the cyclic capability but also improved the recovery performance after abuse over discharge.
