Rusty BobNikon EN-EL9a (1250 mAh) 100% compatible/fit (for Nikon) D40, D40x, D60, D3000, D5000 (premium quality) - Only battery

Seems to work well in camera. Far cheaper than a Nikon. Only time will tell as to actual quality.

Very good quality batteries at a great price.

All good worked fine and charges on Nikon charger
