New replacement battery for MacBook Pro not recognised
I replaced my Macbook's battery (after following the guide from iFixit) and the computer did not recognise it.
The only way for me to turn it on was to plug in the MagSafe connecter (which only showed the green light).
I then asumed it was a problem with the replacement battery (from eBay) and put back the original battery.
For some strange reason, the original battery wasn't recognised either!
I've reset the PRAM and SMC, but still to no avail!
I would greatly appreciate your help!
Update (10/02/2020)
I have a late 2011 mackbook pro which battery indicator showed not working/replace battery soon, replaced the battery with one I bought from ebay. When installed worked as it showed to have 60 % change out of the box, I went ahead and charged it fully and then it drained after a couple of days and would not recharge. Waited a couple of days, it charged a 2nd time and this time i did SMC reset and calibrated as suggested. After the 2nd charge ran out, it started to drain fast and would not charge while plugged in. Replaced with the old battery, charged one time and now back neither old nor new battery will charge, megasafe doesn’t light up at all. Any suggestions?
Is this a good question?

I replaced my battery (2x - first one like a transplanted organ failed after 22 minutes (even after a full charge). So, I called Ifixit and they promptly (thank you) sent out another one. I replaced it, It seemed to be working fin after fully charging it (per instruction); then this morning, nothing when I turned it on. I tried the option, control PR reset; still nothing. I opened up the computer, using my spudger disconnected the battery again. Placed it back in place and turned it on and miracle of miracle, it worked. I put it back together But for the second time in a row, the clock/calendar had to be reset. (I hope this doesn't mean it will fail again because I want to replaced the HD and memory next.) Any ideas of what might be going on?

I've replaced a battery for my Macbook 15 Retina 2012 and I've reset SMC and PRAM and nothing happens,
Fans works at high speed, keyboard backlight fail and all the SMC symptoms.
Any Idea?
