This might be a dumb question but did you check if any of the small smd components (4 to 5) right above the battery connector were knocked off or damaged? This happens a lot when a tool or nail is pried too deep when attempting to unplug the battery. Those components right above battery connector are responsible for reading battery data / information from the battery itself to the logic board.
