Can I connecting charger directly to battery?

Do not do this. The battery is only meant to be charged by a charge management chip in the phone. That chip regulates the flow of electricity into the phone, preventing it from charging too quickly or to too high of a voltage. If you connect a power supply directly to the battery terminals, the battery may overcharge.
