@nick if you buy it for the motherboard you might be okay. As for the battery your guess will be as good as anybody elses. As you know voltages are not a prime indicator about the condition of the battery. In order to determine the health of the battery you would at least have to do a discharge tests, full cycling testing as well as battery management system monitoring. Voltage tests and Ohmic test are not effective for this type of battery. So, if it works for whatever long, consider it a bonus. Do not bank on it being any good at all.
