Yesterday a was fixing a similar problem and it was the connector that plugs in to the logic board. This battery as clearly been reworked at the factory even though the unit was sold as new. The unit wouldn’t start and constantly cycle on off and didn´t charge. We took the battery out and charged directly with some pins. When we put it back we notices that notices that there was only 1.5 volt on the board and 4 volt on the tabs when the unit tried to boot up. On the battery tabs there was 4 volt all the time. I followed the voltage drop to the connector and found two dodgy pins on the negative terminals.
