Hi I’m having issues sometimes with a new battery. In Genius Bar check correct battery health. The problem is that the battery state changes from goog to poor state and the system suddenly stops using it . Have or not the charger, stop using it. So if you do not realize and disconnect the charger turns off and if you have the charger turns off directly . When this issue occur it’s necessary make a smc restart and wait to fully battery charge. Otherwise battery seems dead. In powermanagement log, Feb 24 02:33:59 MacBook-Air-de-migue powerd[56] : Battery health: Poor; was: Good; reason Permanent Battery Failure Feb 24 02:44:05 localhost powerd[56] : Battery health: Poor Feb 24 02:44:07 localhost powerd[56] : powerd process is started Feb 24 02:44:07 localhost powerd[56] : Summary- [System: No Assertions] Using AC(Charge: 77) Versión de la ROM de arranque: MBA51.00EF.B04 Versión SMC (sistema): 2.4f19 I appreciate any help . Thanks Update (02/27/2016) I made the snaps with the ‘poor’ indicator, this time when I remove the charger not turned off. I have made a smc reset and take new snaps with battery state ‘good’.

I think you have a deeper problem here. Before you swap out the battery again do a thorough inspection for corrosion or any damaged components on the logic board (both sides).
