New iFixit Battery not charging

I bought a replacement battery from iFixit in January this year, today was my first opportunity to change the battery, completed the process successfully so I thought, but nothing happened when I tried to power up. (Wondering if it's the fact I've waited 10 months?) Macbook worked when I connected mains magsafe. What could be the problem?

Opened the back again, disconnected then reconnected the battery connector making sure I pressed down... Replaced the rear cover, connected the magsafe mains supply and it's now showing a charging battery... Happy Day's

Thought I’d cracked it, charged up to and beyond the 2 1/2 hours to take the battery to 100% , was attempting to do the Battery Calibration recommended by iFixit so removed the MagSafe power and MacBook went off, nothing happened when I pressed the power on key.. Put MagSafe lead back on now MacBook just keeps going through the start up Apple logo white power up line but switches off as soon as it gets to the end over and over again… What the hell’s gone wrong ☹️😢

I would also install this gem os an app to monitor your battery CoconutBattery. Post a snapshot here for us to see.

First, check the integrity of the battery. If your laptop comes with a removable battery, take it out, and hold the power button down for about 15 seconds to drain any residual power from the device. Then, with the battery still removed, plug in the power cable and turn the laptop on

Regards,

Will

OK, let’s give this a try, carefully disconnect the battery from the logic board, with nothing connected press and hold the power button for a good 15 secs to discharge the logic board. Now carefully plug in the MagSafe charger, your system should spontaneously start, let it finish and do a proper shutdown. Now reconned the battery and restart your system. Let it run a good 10 minutes off battery and take a fresh CoconutBattery snapshot, now plug in the MagSafe charger the system should start charging the battery again, take one more snapshot and post both here for us to see.
