MacBook doesn't recognise new battery

Hey all

So I got a second hand original battery because mine is quite swollen at this point.

I can’t power it up after I changed it from the power button.

If I disconnect the MagSafe charger the Mac shuts off.

After replacement I hook it up to the MagSafe charger and LED’s are orange -> green -> orange

Mac says “replace now” etc. Tried SMC/NVRAM reset to no avail.

when I swap my original battery everything is good.

When I swap back to my original battery everything is working fine.

@georgezz - Coconut is reporting Charging with 0 Watts which tells me the control/switching logic is in trouble. You logic board needs repairs. A common cause is using a knockoff charger!

When I swap back to my original battery I get a random number reporting charging with ** Watts

Try anther new battery I doubt it will be any different. The top thermometer bar is the battery charge. As its not moving up the battery is not charging, yet the charger is offering enough power to run. So it still comes back to the logic within your system.
