+## ECR030.001 Charging until 98% battery level (Ubuntu 22.04)
+
+**Test description**
+
+This test aims to verify if charging the battery stops when the battery level
+reaches 98% mark.
+
+**Test configuration data**
+
+1. `FIRMWARE` = Dasharo
+1. `OPERATING_SYSTEM` = Ubuntu 22.04
+
+**Test setup**
+
+1. Proceed with the
+   [Test cases common documentation](#test-cases-common-documentation) section.
+
+**Test steps**
+
+1. Power on the DUT.
+1. Boot into the system.
+1. Log into the system by using the proper login and password.
+1. Open a terminal window and execute following command to check current battery
+    charge level percentage:
+
+    ```bash
+    cat /sys/class/power_supply/BAT0/capacity
+    ```
+
+1. Note the results.
+1. If the battery level sits below 95% mark, plug the charger into the DUT.
+1. If the battery level sits above 95% mark, wait until the DUT's battery
+    discharges to below 95% level and then plug the charger into the DUT.
+1. Wait until the DUT's battery charge level reaches 98%.
+1. Open a terminal window and execute following command to confirm that the
+    battery charging stops at 98% mark:
+
+    ```bash
+    cat /sys/class/power_supply/BAT0/status
+    ```
+
+1. Note the results.
+
+**Expected result**
+
+1. The output of the `cat /sys/class/power_supply/BAT0/capacity` command should
+    contain information about the current battery charge level.
+1. The output of the `cat /sys/class/power_supply/BAT0/status` command should
+    contain information about the current battery charging status.
+    Example output:
+
+    ```bash
+    not charging
+    ```

+## ECR030.001 Not charging between 95% and 98% levels (Ubuntu 22.04)
+
+**Test description**
+
+This test aims to verify if charging the battery does not start after plugging
+in the charger into the DUT when the battery level sits between 95% and 98%.

+1. If the battery level sits between 95% and 98%, plug the charger into the DUT.
+1. If the battery level sits below 95%, plug the charger into the DUT, wait
+    until the battery reaches the level between 95% and 98% and then unplug the
+    charger and plug it back in into the DUT.
+1. Open a terminal window and execute following command to confirm that the
+    battery does not start charging:
+
+    ```bash
+    cat /sys/class/power_supply/BAT0/status
+    ```
+
+1. The output of the `cat /sys/class/power_supply/BAT0/capacity` command should
