A Sealed and Maintainable Battery

摘要

A new sealed and maintainable battery has two hermetic channels designed in the traditional shell, one for air collecting and the other for liquid-compensating, which are used to elicit the air in each single grid for the unified management. When the battery needs maintaining, the work will proceed through the liquid-compensating channel, and the quantity of liquid in each single grid will be controlled quantitatively using a particular device. So it is a battery of totally new structure with sealed and maintainable performance.
