My 44155C keeps beeping even after resetting and changing batteries

Try changing batteries and hit reset button?

Reset BIOS by removing coin battery.

Take the battery out and leave it for 30min replaceand it should reset itself

Your battery is probably out of charge.... Try charging it.... If the red light keeps on blinking even after charging it for a sufficiently long time You will either need to
1. Change your Battery.
2. Perhaps change your charger.or get your charging port checked and repaired.

Ours keeps chirping even after we replaced the battery. I'm not sure how to fix it.

We are going to try and clean it but if it keeps doing it after that then I guess it means it needs to be replaced, right?

Did you try a system reset? You should be able to bypass.

To figure out what's wrong with the UPS, first you have to do a few things.

When calculating the rating a UPS can handle, it's voltage x amperage. If it's Watts multiply the number by 1.67 to give the rating of the device.

Add up all the devices (use the power supply rating in the computer) as well as any other device, and add them up.

If this rating was exceeded, then you have overloaded the UPS. If it was too long that you did this, then you wore out the battery.

When a UPS beeps even when not connected, that means the battery is very weak.

If the battery is more than 3 years old, it will need to be changed. If the online tests of the unit were done and the battery doesn't need replacing, then other parts of the UPS need fixing.

Check the battery.

UPSs will beep when unplugged to tell you that the mains is off! Overload should reset if you disconnect both the load and the power.

on the back of the packaging for the HUNTER MODEL 44155C it states that it is not compatible with heat pumps

It sounds like you need a new battery (this is what the beeping is) even though its only a year old the battery needs replaced!
