Where to Purchase Accessories for T400?

I am looking to purchase a T400 9 cell battery and the ultra bay battery (replaces dvd).

I looked on the levono.com site, but could not find anything.

 

This post has the part numbers, I've just started looking at 3rd party retailers as Lenovo has an 8 week wait on some batteries.

The Ultrabay battery is in short supply at the moment as far as I know.

For the Ultrabay battery, search for 40Y6789, you will find it out of stock on a lot of places. In my country it is at stock at a lot of places, but that's not strange since they ask €130 for it (that's $190)

I would definitely NOT go 3rd party on batteries since they are mostly a lot worse. Sure they claim more capacity, you might probable even get 10% more capacity. But after those first month (or three) you see that the capacity is down below a genuine and a year later you can trash it.

I've seen this too many times and that why I don't buy 3rd party batteries anymore.

 

Thank you!
