External battery charger for Librem5

I own an additional battery, an universal charger and I charged it with this external charger (specs are visible below). The battery shows now 4.303V. As I read in this and other threads:

  1. I should not insert the battery with this voltage. correct?
  2. What should a resistor has as Ohm (Ω) to discharge the battery externally before inserting?

UPDATE: IIRC my electronic school, a battery of 4500mAh and 4V which will be discharged in 9h means that this is done with: 4500mAh / 9h = 500mA = 0.5A and following R = U / I means: 4V / 0.5A = 8Ω. A I wrong?

Thanks.
