If
the laptop battery is more than 3 - 4 years old then the battery could be worn
out. Rechargeable batteries have a finite number of charge and discharge cycles
and will lose their charge capacity over time, i.e. won't charge to 100% and
gradually the charge reduces until the battery won't charge up at
all. OR
The battery shows a 100% charge but when the adapter is disconnected the
battery drops off to zero capacity in a very short time. If
the battery drops to an unacceptable charge level then the battery needs to be
replaced.
It sounds like the battery is compatible with the ups.
However, APC has excellent free phone support.
I recommend that you give them a call.
Be ready to give them the model number and serial number for your UPS.

Sounds like a lose or burnt charge terminal. Fixing would require disassembling the laptop and resoldering the loose or broken connections. You might want to try a different AC adapter first.
No batteries do not charge
12 V Battery charger does not light up when plugged in. Does this mean that it is not charging??
What to do?
Does the charger still charger the batteries?
