Battery is an electricity source, electricity in battery comes from chemical reactions inside it. When you flow electricity to a bulb, it glows and especially for older bulbs it become very hot. By now, I'm sure you know what's the energy conversion between battery and a bulb. I've given more than enough clues.

The battery's electrical power out put can be used as the imput to the Lighting producing system.
It basically follows the 1st & 2nd law of thermodynamics.
The out put of the system is the power remaining in the system.
In the case of the lighting system which is the incandescent bulb it use electrical power from the battery and the result is electrons flow in the fillament whcih heats up to a high temperature and radiated light energy. However the out put electrical power is less than the Input. This is in agreement with thermodyanics laws.

A battery only stores charge. Light bulbs are transducers that change electrical energy to heat and light through resistance.

Chemical energy converts to light, infrared and heat.
At the end the radiation is converted to heat.
Heat = thermal energy = kinetic energy of the molecules.
