**Q: is this compatible with T430?**
A: I ordered the battery for the Lenovo E420 and the battery worked OK, but doesn't seem to hold a charge any longer.  If the battery specs for the T430 and the E420 are the same the battery should work as well for you as it has for me.

**Q: Can you tell me if it's ok for a lenovo thinkpad 0578pcy? I guess it is but I want to be sure. Thanks.**
A: Don’t know using on a t450s

**Q: What is the operating time provided by the battery????**
A: Depends on the laptop.  My T420 would get about 3.5 hours from this battery when the battery was new.
