Short answer: NOWHERE

Long answer: Spare battery market is flooded with second-grade (typically 
asian made) battery cells which simply do not perform as good as original 
(but are cheap). If you manage to get *original* battery, you're good. It 
could cost about US$150+.

Batteries are repairable. There's a controller and cells, 3.7V each. You can 
replace died cell(-s) and be happy. You can get a cell out of another battery 
or in a repair shop. Be warned that Li-Ion cells are not freely sold 'as is' 
compared to Ni-Cd batteries. That's because improper use of a Li-Ion cell 
could result in severe burns and\or explosion. Lithium is an extremely 
aggressive metal. It violently burns in open air. You are warned.Don't blame 
me if you're hurt.
