Nicad Battery charger include voltage limiting

In this my circuit , which is one of a series of simple battery charger , but this circuit to charger the Nicad battery . This circuit included with current and voltage limting . Why use it ?? because with current voltage you can choose voltage to charge a battery , and the limiting voltage use limit voltage if the battery is fully, because if battery fully that damaged quickly.
