[PRO1] Surface pro 1 battery problems

I have a surface pro 1 and I'm experiencing some weird battery issues and just wondering if there's anything I can try to sort it out.

I noticed a few months ago that the battery icon display was pretty erratic and would take a while to count down even when it's been on the battery power for a while, but now it's got a lot worse it will just sit at 100% even though it's been running over 3 hours and eventually it will just turn off without showing a low battery warning or anything. I've installed pure battery analytics and that is the same, the odd thing is that program show my design capacity as 42002 but full charge capacity as 87594 mWh

Obviously that's not right and it shows the same reading in the windows battery report, I've tried installing Microsoft AC adapter and ACPI control method and let it reinstall itself but there's no difference. It still just sits at 100% and 9 hours run time remaining. I know it's pretty old and the battery is probably well past it's lifespan but is there anything I can try to get it showing the battery state correctly or just forget about it and keep it on AC power.

Thanks 🙏
