After changing the battery my MacBook Pro won't boot up

I checked that connection and the other ones too. Everything is fine. Can the cable be damaged even if it still looks good? I checked the battery voltage after charging it for an hour or two and there was no increase. So I don't think the battery is getting any power. Is it possible that something happened to my logic control board when I took it out?

@jms83415 - Over bending and sharp creases can damage the cable. Could you have damaged to ZIF socket? Post some pick on the connections here so we can see get in tight with lot of light.

As the battery was swollen and if the battery had already been replaced before then it’s possible the charging logic within the logic board is having issues.

Let’s get a better view of things install this gem of an App CoconutBattery post a snapshot of the apps main window here as well.
