Dyson DC44 for spares or repairs (Glyne Gap TN40)

Dyson DC44 Animal stick cleaner.- Not working!- It packed up a little while ago and I bought a cheap battery from e-bay. It has packed up again. It may be that I bought a duff battery, or it may be something else. It comes with the charger an an assortment of heads. So could be a source of accessories. Or a repair project.
