How is the battery life for a lenovo thinkpad t410?

The ThinkPad T410 is available with a standard 6-cell battery or an extended 9-cell unit. Using the LAPTOP Battery Test, which involves continuous surfing over Wi-Fi, we found that the integrated graphics T410 lasted 3 hours and 53 minutes with the 6-cell battery and 6:02 with the 9-cell.

Three to four hours with the small battery and five to six hours with the large battery that's assuming that you're using it if it's simply in sleep mode it will last most of the day
