The below info is only true if your battery still works and you didnt completely fry the inside of it of course.
Here is the info:
There _is_ an effect which can mimic the "memory effect", in the
sense that it makes the battery look as if it is losing capacity.
This effect, known as "voltage depression", occurs if you
over-charge a battery. The battery's output voltage drops from
1.2 to about 1.05 volts partway through the discharge cycle, and
this may "spoof" a power-monitoring circuit into believing that
the battery is exhausted.
Voltage depression is curable. It can be cured by fully
discharging each cell of the battery... INDIVIDUALLY... all the
way to zero, and then recharging the battery. You can do this if
the battery design allows you to access the individual cells. You
can't do it if you can't get to the individual cells, but only to
the battery terminals.
Alternatively, you can discharge the entire battery until the
total voltage drops to 1.0 volts per cell, and then recharge
it... do NOT try to discharge the battery all the way to zero, or
you will very probably damage it. This 1.0-volt-per-cell shutoff
should be safe (in particular, it leaves a good safely margin for
any battery rated at a nominal output voltage of 6.0 or less) and
should discharge all of the cells well past the
voltage-depression point.

alot of the new battery have the technolgy in them so the memory affect will not ocour if my sources are incorrect let me know thanks
