What does the law of conservation of energy state?

Example- I can crank a generator, and charge a battery, changing mechanical energy to electrical, and use the battery to run a motor, changing electrical energy into mechanical. I cannot get MORE electricity out of the battery than what I put in- and both charging the battery, and running the motor "lose" energy- in the form of heat from friction. But when you add the waste energy to the electrical, there IS no "loss"- total amount of energy is unchanged.
