Query: nearly dead within 9 months

Purchased one of these about 9 months ago for our Canon Powershot G3, and we're already having big problems with it. Also, a few months after we started using this battery, the camera's sensor died and had to be replaced at a cost of about $150 + shipping. Was the sensor problem related to the use of this battery? I don't know that it was, but I can't rule out the possibility.
