Query: Less than 6 months it wont hold more than 40% charge....NOT GOOD!

Purchased in October 2010, worked fine at first, held a full charge, now 6 months later, only can hold a 40% charge. I would strongly discourage anyone from buying this item. I cannot return the item since its labeled as a "hazardous material" according to Amazons return policy. Buyer beware.
