Troubleshooting Tips:
1. Restart the Pool Cleaner, as this may resolve a temporary system issue.
2. Check the ambient temperature. If the temperature is below 10°C (50°F), the battery protection system may prevent normal charging. Move the Pool Cleaner indoors to an environment above 10°C (50°F) for approximately 30 minutes, then try charging again.
If the issue continues, please provide:
1. A short video showing the battery indicator behavior while the Pool Cleaner is connected to the charger.
