Entering I2C Commands for BQ40Z50

SMBus Commands are not working like they should to re-enable charging and discharging for some of the battery packs I'm working with.  No matter what I try, the batteries will not charge nor discharge, but every thing shows the battery is good.  Yet when I try to use the device or external charger, they do not see the battery.  So I thought I would try I2C Commands.  But since I have never attempted to do this, I sure could use some help getting started.  How do I enter the I2C command structure using the NLBA1 I2C subtab?  

Thanks in advance.
