Looks like the program can't read/decode the chip in the battery.

Try the battery data in HWINFO32:

If the battery supports the Smart Battery Specification, it should
produce the required numbers.

I don't have a working antique laptop handy to see if it works any
better. Maybe later. Also, I've had problems reading the data from
various no-name replacement batteries purchased on eBay.

I ran the battery until it shut off. Then rebooted on AC power and this is
the report from HWINFO32 says:

Well, HWINFO32 got the Chemistry correct, which is critical because
that's what chargers are suppose to use to determine if they should
try to charge the battery, or simply power the laptop.
