Question

__________ batteries are designed to be recharged and used a number of times.

Answer 1

1. A battery converts chemical energy into electrical energy.
2. Secondary batteries are also called rechargeable batteries because these batteries can be recharged after use.
3. A secondary battery can be recharged by passing an electric current through the electrodes opposite to the direction in which the electric current is produced by the battery.

Hence, secondary batteries are designed to be recharged and used a number of times.
