It is likely you have a faulty battery. It could be just one in the unit or all of them. They can also have the memory effect. This is because they are Ni-Cads. You can try waiting for them to go flat then leave for an hour then fully charge for 24 hours. Then discharge fully and recharge again. Doing this sometimes allows them to recover but is not guaranteed. If you are competent with soldering you may be able to replace individual cells but it is better to fit all new cells to restore normal use. This is an environmental method rather than dumping into landfill and buying new. Each cell is 1.2 volts so whatever the voltage of the battery pack will be divided by that. It may be possible to replace the battery pack but that could prove costly if they are still available. NiCads are available on the internet at a reasonable cost. This is a link to the user guide:
