iMac battery recognition

[Calperon]

I have a mid 2009 iMac Pro that will not accept an updated OS but which I need to keep alive as my new iMac will not run Photoshop. I did not use the MacBook for a while then when I did it would no longer charge the battery but will run perfectly on mains supply. The cable charge light showed green but the computer told me I needed a new battery so I installed one (the correct one) but the computer still will not charge up and it tells me I still need a new battery. I have seen several work-arounds on the Internet to resolve it but none have worked.
Any suggestions?

OK, thanks. That System Info is from the iMac.

-Do you have the info for the MBP Mid 2009?
-Does the battery show as installed in  > About This Mac > System Report > Power?

it does indeed show the battery as installed but even stranger, I left it plugged in to the mains for a couple of days without it charging, then the charging plug turned red and now without me touching the computer, the battery is at 100%.
Perhaps the fairies are back from their holiday?
I must thank you for bothering and hope the situation remains stable and the charging does not stop again. I cannot imagine what else to do.
Do have a good weekend and thanks again.

No worries...glad it is working.

An SMC reset might help if it happens again.
