system processes taking all the CPU, battery replacement problem?

MacBook Air early 2014 Dual Core i5

MacOS 11.7.2 Big Sur

I replaced the battery (iFixit) and the machine worked fine for awhile, but now it's unusable because system processes (as seen in Activity Monitor) are hogging the CPU.

No liquid damage, BTW

Did the usual, battery recalibration, SMC/PRAM reset, ran Disk First Aid, Diagnostics (says SMC and camera error), and re-installed the OS (but didn't erase the disk first).

SMC error code PFM006

PMS error code PPN001

Any suggestions?

Let’s see what the battery looks like. Install the gem of an App CoconutBattery it will allow you to get a better idea what’s happening. Take a snapshot of the apps main window with the battery tab extended also make sure the charger is plugged in too.
