Battery Problem Toshiba

[FEM_BOT_01]

I have a toshiba p755 windows 10 laptop and i dont know if its a battery issue or system
what does this mean 1 mn until fully charged

It means the battery is charging and has one minute left until fully charged.

i purchased a used labtop and seems like the person that shipped me the laptop had placed in the battery incorrectly

what is the maximum hours for a p755-s5120 toshiba laptop to be charged

would it be 4 or 6 hours?

I'm asking because after i shutdown my laptop correctly and took out the battery and replaced it back in it said 6 hours , instead of 4 hours
