Bought these from a place called DinoDirect (thought I'd try them).
UltraFire - LiFePO4 - 3.0V http://lygte-info.dk/review/batterie...n%29%20UK.html
Ultrafire Charger - http://www.dinodirect.com/UltraFire-...FUie4AodKXwA7A

Never again.

Batteries were fine (nothing great, but not garbage), but the charger was cheap junk.
1st one - would not charge and "hummed"
2nd one - would not turn on
3rd one - they would not send me a 3rd one, and refunded my money for the charger and batteries (after I complained that I can't use the batteries w/o a charger)

I pulled the chargers apart, and found cold solder joints, and some that had no solder/reflow on them..just a wire/IC leg in a hole, bouncing around.

I ended up just building a charger. (Couldn't fix the other two, as the charger control IC had shorted out

The batteries are fine. Hold a charge OK and recharge OK.
