Query: Not a happy buyer

I purchased this battery for my iPAQ thinking that I could get a few more years out of it. The new battery works a little better then the original battery that is 7 years old. It went back! I am in hopes that the replacement that they send will hold a charge better then the first one they sent. Thank goodness I purchased it from Amazon and not a third party vendor!
