Question Problem with Motorola MC659B barcode scanner (OS boot!)?

[Ksingh707]

I have a Motorola MC659B-PB0BAA00100 barcode scanner.

1. Every time I power it on, it says "OS boot!"
2. After that the screen says "battery too low, shutdown device" even though I have a fully charged battery in the scanner.
3. I will attach photos below to show what I'm seeing.
4. If anyone can recommend or know any resolution, I would appreciate it. thanks

have you checked the voltage on the battery?
