Nice and cheap compared to the Lenovo/IBM equivalent. I'm getting 2-4 hours of run time depending on usage. Battery plugged in just the same as the original, so no problems there.I'm happy with the purchase and would recommend it.
The laptop battery was as advertised and at a reasonable cost, as compared to other suppliers.
