BAtteru Compatibility for Canon PowerShot SD10?

[bobo21]

This is so confusing about the battery compatibility. I bought on ebay a replacement for the NB-3L battery for my Canon PowerShot SD10. Turn out when I ask the guy he said the manufactuer told him it is only compatible with the Canon PowerShot SD100. I called up Canon and they told me the SD10 and SD100 uses the same exact NB-3L Lithion battery. I wonder why some NB-3L only go with SD100, and some go both SD10 and SD100. Anyone have same experience or any solution? Hey Steve, you think you can figure this out? Thanks..
