Answer / kj

The problem is that while DC current flows in one direction
only AC reverses direction every half cycle.
What this means is the when connected with +ve to +ve and -
ve to -ve DC will flow into the battery and charge it. With
AC you will have +ve to +ve one half cycle and -ve to +ve
the next half cycle. In effect you will charge the battery
one half cycle and discharge the battery in the next half
cycle. Although in reality you would probably damage the
battery.
