I have acquired an admittadly fairly old camcorder, a Sony CCD-TR202E from the early 1990s i think, the camera works ok but i have a question about the battery belt that came with it.

If you look at the attached set of photos you can see the belt in question, the problem is it doesnt hold a charge anymore, its only lasts a few minutes then dies.

My question is, can i get a similar battery belt or long lasting power pack for this camera, or i can replace the 6 silver metal batteries you can see in the photo ?

Thanks for any help you can give,
