Until it's fully charged
That's so Zen.

As Enaud said, it depends on the charging rate, and I would also add to that the state of charge of the battery before it goes in the charger.

In theory, if you have a 4200 mAh battery at 50% charge state and a 500 mAh charger, it would take a little over 4 hours to charge. If it were fully discharged, it would take a bit over 8 hours.

With a 1 amp charger, that time is cut in half.

Hi how long do i have to charge a 26650 3.7v 60a 4200mah battery ? TIA! :)
Nothing more to add except I hope you are aware that your battery isn't really a 60 amp battery. A few shady manufacturers (Imren, Vappower, Efan) advertise those exact specs, but in reality those specs are either over-rated or a pulse discharge rating, not a continuous discharge rating (CDR). In vaping, we are only concerned what the CDR is. Especially if you are using sub-ohm coils.
