Extended Battery Pack goes on sale

For use with both the PSP-1000 and PSP-2000, this extended battery kit will increase your PSP's battery life up to 80% more life. It'll create a small bulge for owners of PSP's slimmer model, but the significant increase in battery life may make it quite worthwhile.

It's now available for purchase at GameStop for $45. Use coupon code SAVER to get free shipping.
