Battery Life Question 86Wh vs. 94Wh

[mikeynavy1976]

Just curious. I have a Lenovo W510 that I bought soon after they first came out. It came with a 86Wh 9-cell battery. Now, I notice that Lenovo's replacement battery is a 94Wh version. What is the typical performance difference between the too. If I decided to swap out batteries would I see a noticeable increase in battery life?

if they hold true to the ratings you should get about 10% better battery life
