You can "change" a torch battery. If you mean "charge", there are plenty of types of torch battery that can be charged. The common carbon-zinc battery, commonly used in torches in the past, is one of the few types left on the market that can't be charged.
When you cleaned the torch did you also put a fresh, clean battery in the torch and test the bulb to see if tht works as well
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
A torch (flashlight) battery is a dry cell, and is not designed to be recharged.

More likely used for a toy car.

they are two different types of batterys, the car recharges it's battery as you drive, that battery is a rechargable battery. the torch does not have a rechargable battery but you can add one to it.
