lithium batteries is that the same as a li-ion battery in my bike?2004 lithium battery? No thanks!

I think your right it and I bet it needs a new battery very soon.Yes, yours is also a lithium battery.
As for their spiel, they are selling of course, and one might wonder the reason for sale if it suits so well! That the project completed in 2009 is irrelevant, the battery is probably six to seven years old and even the newest generation e-cars about to be launched only confidently claim four years lithium battery life.
Of course if the battery has been replaced at some time it could be different, but I think they'd have mentioned that.
