One of my Pronto TSU9400's battery doesn't last long - just a few minutes and then I get the low battery warning. I'd like to get a replacement.

I understand that the TSU9400's battery specs are:

3.7vdc 1700mah/6.29kwh, lithium/polymer

(and need a T6 Torx).

Are these generic batteries or custom made specifically for the TSU9400?

I found a few threads regarding TSU9400 batteries, but they're quite old (seems, isn't around anymore). I did an online search and I see some places that advertise TSU9400 batteries. But, I'm just wondering if I were to get a new battery if it is something that may have been sitting on a shelf for many years.... Anyone had to get a new battery recently and have recommendations on source?
