You can still purchase this battery through your local Great Planes authorized hobby dealer or through Tower Hobbies.
The stock number on this battery is:
FUTM1430 NT8H TX NICD 9.6V 500M J G PCM retail price $39.99
And Eloy is correct, while it may look like it has 9 cells in the pack, one is actually a "dummy" cell.
