Battery Replace - Wireless Pro

Hello,
Does anyone knows where can I Buy a new battery for My Passport Wireless Pro?

Thanks,

I am also looking for a new battery for a wireless pro. The device is 3,5yers and looks like, the battery of it had an internal shortage. Now the measured voltage is 0 flat. Anyone, can You help please, as I can’t find anything on the Internet?!

Here’s the ridiculous answer from Western Digital support:
"I would like to inform you that the battery of the My Passport Wireless Pro cannot be replaced, only the entire product can be replaced. "

It’s possible to replace battery’s from Laptop’s, Smartphones,… but from a portable disk is not possible?

Now i’m waiting new battery’s and I will try to replace.
Let’s see if it works.

It’s a Samsung battery.
