Q4: Is it beneficial to send in a B112C with the H28 software to upgrade to the newest level? At what cost?

A4: The H31 software includes a better way of detecting the peak charge of NiMH batteries to prevent overcharging and damage to the cells. It also makes some changes to the display. The cost to update the software on the BC112 is $50.00 excluding shipping and handling. The turn around time is quick.
