When you stop a T2 instance, all accrued credits are lost. When you relaunch the instance, the CPU credit balance has zero credits plus any allocated [launch credits](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstable-performance-instances-standard-mode-concepts.html#launch-credits). For more information, see [Monitor your CPU credits for burstable performance instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstable-performance-instances-monitoring-cpu-credits.html).

To see the launch time of your instance, follow these steps:

1.  Open the [Amazon EC2 console](https://console.aws.amazon.com/ec2/), and then choose **Instances** from the navigation pane.
2.  Select the T2 instance.
3.  On the **Description** tab, review the **Launch time**.
