      Aside from getting a replacement power adapter, your best option requires knowledge of electronics and soldering skills.

      DO NOT DO THIS UNLESS YOU HAVE THE SKILLS AND KNOWLEDGE!!
      IF NOT PROPERLY DONE, THE BATTERY COULD EXPLODE!!!!!!!!!

      Too charge a battery outside of a laptop, you need to build a holder that makes electrical contact to the battery.

      Then, connect the battery to a good quality bench power supply.
      You NEED to control BOTH the current and the voltage to charge the battery without damaging it.
