4.2V ~ 70mA (low) ~3200mA(High)"

So which battery: this: http://www.dealextreme.com/details.dx/sku.29031 with 2500 mAh
or that: http://www.dealextreme.com/details.dx/sku.26249 with 3000 mAh

or something in between? Does it matter, will both work. Will one work better than the other?

Thank you

None of the DX pics are coming up at the moment, some sort of problem. But I remember looking at that light a while back based on some of the comments/reviews.

I have had really spotty performance with some of the DX ****Fire batteries. Batteries in the same shipment arriving DOA or varying in length by 1-2mm. Posts in other forums have indicated the same spottiness: some people swear by them and others swear at them.

If you read thru the comments for the Ultrafire battery you'll see mention of them leaking after 3 cycles. Things like that with the inherent dangers of Lithium batteries gives me pause. I did some research on Li as to performance, reliability, quality etc and found threads at CPF including graphs etc (which I cannot find now to reference). What I took away from the readings was:
* TrustFire and UnltraFire are pretty equivalent and vary as to quality
* UniqueFire is a cut below (cr@p was the technical term used)
* AW is more expensive but actual capacity was much closer to stated, with better/additional protection
* WolfEyes are comparable or better than AW at least as to performance.

Lighthound sells the AW brand. They cost more than the WhateverFires but peace of mind has a value as well.
