I reviewed your post and I understand that you want to know how long you should charge the battery for the first time.
Don’t worry, I assure you I will try my best to get this sorted.
Charge the battery till it reaches 100%. The battery stops charging automatically when it reaches 100% even when you have the charger connected to the computer. The battery starts charging again only when the battery percentage drops below 95%.
I hope that answers your question and you have a great day!
