What batteries are you using, Ni-Cad or Nimih sorry Nicad or Nical metal hydryd and what size of cell normall AA or Sub-C, and what capacity, if you measure the size of the individual cell and let me know what is written on them I can advise you.

Good advice from striderjg never discharge a nicad or nimh cell below 1.2v per cell as they will reverse polarity, however nicad and nimh cells will decrease in capacity if just charged and discharged on a regular basis, they need periodic deep discharge (but not below 1.2/cell) to maintain max capacity.
