Query: Didn't work

I bought this battery to have a second one besides the one that came with my HP Jornada 568, and unfortunately it didn't work at all. After I plugged it, and charged it (it miraculously charged in 10 seconds?), it quickly discharged after 2 seconds of use. I then took it with my PDA to an authorized HP tech service in my location and they told me that the battery was useless.
