What's the minimum charge current when charging one battery?

The minimum charge current is 300mA.

Do this have the option to discharge and charge?

It has a charge & discharge option, but I find the readings on the charger do not match with the readings from my dedicated measuring instrument, i.e. the charge and discharge readings.
