I'd bet it's a battery problem.
How old are those batteries?
I'm not asking when you bought them.
I'm asking when they were manufactured.
A battery that has been sitting for five years in a shipping container
sitting in the sun in Arizona is not a new battery.
They self-discharge and the battery protection disconnects them.
If the cells are imbalanced, simply discharging it till it quits
can take it out of service permanently.

Battery protection circuits and results vary considerably.
sometimes, you can fix the battery, sometimes you can make it work,
but the battery gauge doesn't work, sometimes can't do anything to
make the protection chip recover and let you use the battery.

I had a very similar problem with a Toshiba battery.

My battery was dead.  Nothing, no charge, no run, no nothing.
I opened it up and recharged the cells individually.
The computer booted from the battery, but the gauge didn't work.
Always said zero charge and ran till it suddenly quit.
And it wouldn't charge.  It always ran from the battery when
the AC was connected.

I could run the thing was off the battery with AC disconnected.
I could run the thing off AC with the battery REMOVED.
Only way it would recharge was OFF with the battery inserted
and AC connected.

Clever strategy to FORCE you to buy a new battery, but still let
you run the machine.

That's the only machine I've ever seen with that draconian battery
strategy.

So, that's my story, believe it or not.
YMMV
