It doesn't sound good. If you can measure the voltage of each cell would help. Something like THIS , or the more expensive but easier to read one HERE which unfortunately is out of stock at the moment. If you haven't got any other way a multimeter would do. If it has got one or two dead cells on a new pack I'd call it stuffed. You could contact them and maybe get it replaced or credit added to your account to it's value. They'll want either pictures of it hooked up to something showing the individual cell voltages or for you to send it back. If they want you to send it back you'll be in for a fairly long process and paying for all shipping involved and if it was me, personaly I would just right it off as not worth the trouble.
I am assuuming that you have tried one of your other batteries on your charger since and it is working fine here.
BTW, I love your cat based disposal method .

You can save a lot of money here compared to hobbyshops and even most other internet based suppliers. There are some ways they have of doing things that take a little getting used to though.
1: If something is out of stock, treat the expected restock time on the page as wishful thinking.
2: There is warranty but since you're mostly dealing with Hongkong and you have to pay all shipping costs it for the most part just isn't worth mucking around with.
3: From my experience the customer service is adequate but some people seem to have much higher expectations than me. I like the low prices and high standards of customer service cost more and so the prices have to go up, so I like things just the way they are .
4: Shipping times can sometimes be very fast, but quite often can take a few days and on ocassion much longer.

Was your Bixler out of stock when you ordered it, and was it from the AU warehouse or the international one?
