Dead Phottix battery

[pmack]

Anyone had problems with Phottix batteries?

I had a genuine canon battery fail on my last camera (40D), so with my current 7D, it wasn't hard to make the decision to try a non genuine battery. I purchased two Phottix batteries (LP-E6 equiv.) on ebay last year, and they worked well, untill i noticed one had gone completely flat.

I put it in for a charge, and after a few hours, I came back to see it continuously blinking. So not the one, two, three blinks, or the constant on, but a continuous blink. I put it in my camera, and it gave the camera absolutely no power. I put the other phottix battery in my camera, and it turned on fine.

What do you think has happned here?
Complete cell failure or something? The "chip" has stuffed up?
Maybe I should return to buying genuine canon batteries. Though does anyone recommend any alternatives?

Thanks
