Solution

1. Preparation

Ensure that the vehicle is parked in a safe location with ample space to conduct tests.
Fully charge the battery to 100% to gather baseline data.

2. Access Battery Information

On the touchscreen, tap on 'Controls' and then select 'Battery.'
Review the maximum range displayed; this indicates the current battery capacity compared to its original state.

3. Evaluate Battery Health Using the Tesla App

Open the Tesla app on your smartphone.
Navigate to the 'Battery Health' section to check metrics such as cycle count and degradation percentage.
Compare these readings with Tesla's specifications for optimal condition.

4. Perform a Range Test

Drive the vehicle in various conditions (highway and city) until the battery level is low.
Monitor the distance covered versus the estimated range to determine if performance aligns with expectations.

5. Record Findings

Document all metrics regarding battery capacity, cycle count, and performance during the range test.
If significant degradation is noted (more than 20% loss from original capacity), consider contacting Tesla service for further evaluation.
