I would be very surprised that you overcharged the batteries to the point
of no function. Your batteries would have to have gotten very hot for that
time (batteries deteriorate in a charger due to evaporation of electrolite
water). Generaly over charging weakens a cell (one battery in a pack) and
gives it a funny discharge characteristic. No life at all means a broken wire
or trace. Take the batteries out, start at the battery pack with an ohm meter
and check the circuit from the battery minus terminal to Ground; and the plus
terminal to: the 5V regulator, the supply for the memory chip, and the motor
supply. When you find the bad spot, solder a wire bridge around the break,
and try to figure out why it blew before putting the batteries back.

I think I overcharged my handyboard, I chargedf it for two days. I
charged my handyboard using the Normal charge method. My handyboard is
not responding at all. There is no power bulb glowing. Do you have any
solution. I had to complete my project.
Kindly reply me as soon as possible.
Thank u
