BATTERY UNIT Russian patent published in 2015 - IPC H01M2/10 

FIELD: electricity.

SUBSTANCE: locations for drainage holes (25) are selected between the first and the second left lead plates (461, 462) which are connected to electrodes (42) of the battery elements (41). The first and the second left lead plates (461) and (462) are lead plates (45) which are located next to each other and have different electric potentials. It is possible to drain the water located between these lead plates (45) outside of the accommodating casing (20) of internal part of the accommodating casing (20). Respectively, even in case when the supporting edge (231) is formed in the accommodating casing (20), it is possible to drain water in such a way that the water located between lead plates (45) is removed. Therefore, is possible to prevent electric connection between lead plates (45) which is probable when lead plates (45) are submerged into water.

EFFECT: possibility of effective drainage of water penetrated into the accommodating casing (20), out of the accommodating casing (20), therefore to prevent the electric current leakage, and to minimise amount of drainage holes (25).
