Question

how does a dry cell with alloy container which do not corrode get dead

Answer 1

Explanation:

Corrosion occurs primarily on the grid, and it is known as a “softening and shedding” of the lead off the plates. This reaction cannot be avoided because the electrodes in a lead acid environment are always reactive. Lead shedding is a natural phenomenon that can be reduced but not eliminated. A battery that reaches the end of life through this failure mode has met or exceeded the anticipated life span. Limiting the depth of discharge, reducing the cycle count, operating at a moderate temperature and controlling overcharge are preventive measures to keep corrosion in check.
