Testing a I167 Segway with dead batteries

[Tallmanneal1]

Hi, I am new to Segways, only ridden them twice! I just bought a I167 and the batteries will not take a charge. Is there a way to hookup an external power supply to the input battery connection to test whether I should invest in batteries?

Anyone ever answer? There is a way if still interested...
