Electrical to chemical energy
Explanation:
If the batteries in a flashlight are rechargeable, the energy conversion that would take place to recharge the battery is from electrical to chemical energy.
- A battery is an electrochemical cell in which chemical reactions produces electrical currents. 
- This is a typical energy conversion from chemical to electrical energy. 
- When such batteries are to be recharged, the revere process is followed. 
- Electrical energy are used to drive chemical reactions. 
- This in turn makes the battery recharged and on its own, it can further chemical reactions to produce electrical energy. 
- During charging, the potential of the battery increases.
