I don't have a Dell source for you, but I'll bump your thread by mentioning TechExcess.net, a fantastic source for HP batteries and accessories. For just over $200, I got a dock, 12 cell battery, extra power supply, media connector, wireless keyboard and wireless mouse. Good communications, everything arrived in new HP packaging, and everything works flawlessly.

Agreed re TechExcess.

Have purchased HP batteries and power adapters from them.
Quick delivery, substantial savings, real humans answer the phone.
