Issues and information on Ni-cad batteries

Question

Write down the issues and information on the Ni-cad batteries.

Answer 1

Ni-cad is used where the long life, high discharge rate and economical price are significant.

Battery manufacturers recommend to slow charge a new Ni-cad battery for 24-hours before use. This initial trickle charge helps in redistributing the electrolyte to remedy dry spots over the separator which may appear when the electrolyte gravitates to bottom of the cell during long storage. A slow charge also helps to bring all the individual cells within the battery pack up to the equal charge level since each cell may have self-discharged to various capacity levels during storage
