From the blister pack mine came in:
"ASP will provide to the original purchaser free replacement Sapphire Lithium power cells and Crystals. To obtain replacement components, send your Sapphire postage paid to:

2511 E. Capitol DR
Appleton, WI 54911
Please include a check in the amount of $3.00 (US) to cover return postage and handling. Be certain to include your return address. Allow four weeks for dleivery."
I've returned two so far ... one with a broken clip and one with a dead battery. Turnaround time was a month.
Too bad Photon's don't have as great a warranty.
