How can I determine how long it takes for these batteries to be full?

I just took apart an old laptop battery.

There are a total of six individual cells (batteries).

Total capacity 11.1 volts and 4400mAh 49Wh 4.05Ah

Now I have an adjustable charger with which I can continuously regulate between 0 - almost 18 volts and 0 - 2 amps.

Can I somehow deduce how long it will take one of these cells to charge?

There's an input voltage on the battery. In any case, you shouldn't take more than what it says there

Only the following can be read on the individual cells

SE US18650GR

T 6F129RH02E

I can't get more from that
