My battery has never said it was fully charged even when it showed 100%. I followed the video tutorials on how to install a battery and condition it and how to install an SSD and boot up with a bootable USB. The videos also showed how screaming fast their “new" mid-2012s were with a timer. I didn’t get to enjoy any of this. I was wondering if I needed to replace the SATA cables.
Also, I had made the mistake of installing the 64-bit OS, then realized nothing worked with it and my Excel spreadsheets were literally backwards. I then erased everything again, re-initialized (again following a tutorial) and loaded Mountain Lion OS and upgraded to Mojave, which is where I’m staying put.
So these are my problems. My Mac is very slow and won’t hold a charge for very long even with the “new" battery. My last battery lasted 9 years. When it’s charged up, I take it off of the charger, use it then close it. When I go back to use it, I have to reboot sometimes several times a day with it plugged in and the battery is at 95%. Sometimes it’s reliable. Right now it’s being a pain. I’m not sure if this is a hardware issue, or if I have legacy files from the 64 bit system when I restored my files and need the “genius” bar. I did see another question regarding the same battery issues I’m having and the responder suggested the coconut battery app. I can’t get it to download and half the time I can’t get access to the App store.

@bmx2019 I believe the fan is running because my laptop is always in my lap and it doesn’t get overly hot.
@dan I tried holding down the D at restart and received an error message about a missing file. I also tried option D at restart and recieved the same error message ‘Cannot load EFI/Drivers/Test/Support.efi. I read through Apple Support looking to see if the .diagnostics folder was in the right place but wasn’t able to find it.
'''EDIT''': According to the Apple Forums it appears the Boot ROM was changed when upgrading to Mojave and option D is no longer available. Downgrading does not change the firmware.
@gizmowizards I did adjust the SMC following online instructions. I've been poking at this problem for over a year now. I haven't adjusted the energy saver settings. On battery and power adapter they’re set at 15 minutes.

I can’t seem to upload my screenshots using the media manager. I add my screenshots, press “Upload Media” it takes me to a new screen. The new screen has a “Back” button and an area to upload media or a URL. When I drag and drop my screenshots into that screen it takes me back to my original screen and the circle continues. What am I doing wrong?

@danj The only way I could load the images was to use a PC (smh). The battery was purchased 7/19, probably installed 8/19:

Charging: No (battery icon shows it’s charging)
My battery has never said it was fully charged even when it showed 100%. I followed the video tutorials on how to install a battery and condition it and how to install an SSD and boot up with a bootable USB. The videos also showed how screaming fast their “new" mid-2012s were with a timer. I didn’t enjoy any of this. I was wondering if I needed to replace the SATA cables.
Also, I had made the mistake of installing the 64-bit OS, then realized nothing worked with it and my Excel spreadsheets were literally backwards. I then erased everything again, re-initialized (again following a tutorial) and loaded Mountain Lion OS and upgraded to Mojave, which is where I’m staying put.
So these are my problems. My Mac is very slow and won’t hold a charge for very long even with the “new" battery. My last battery lasted 9 years. When it’s charged up, I take it off of the charger, use it then close it. When I go back to use it, I have to reboot sometimes several times a day with it plugged in and the battery is at 95%. Sometimes it’s reliable. Right now it’s being a pain. I’m not sure if this is a hardware issue, or if I have legacy files from the 64 bit system when I restored my files and need the “genius” bar. I did see another question regarding the same battery issues I’m having and the responder suggested the coconut battery app. I can’t get it to download and half the time I can’t get access to the App store.
