Is Imagio battery same as Topaz?

[lmtorres]

I think it will be a while until batteries are available for Imagio specifically and I travel a lot and always carry two spares for my Touch Diamond. I read a posting where the Topaz and Whitestone batteries were the same. I've checked out Topaz (TD2) batteries on ebay and they look the same, but I can't tell for sure it will work.

Any thoughts on this?

Thanks,
