Will this work in the Eufy 11+ robo vac?

No, It does not work in eufy 11+ robo.

Will this fit Coredy 500 series vacuum?

I have Tresvor 500 and it fits right, like if I had bought a brand new robot. Check the description, it has a list of items it works with.

Does it work with robovac 25c?

Yes, the battery can work with eufy robovac 25C.

How long does It take to fully charge the battery for the first time after installation? I keep getting flashing light and it's been two hours .

I think that depends on the power source but up to 8 hrs would not surprise me.
