Why does my battery drain below the reserve?

Why does my battery drain below the reserve?

Your battery is designed to stop discharging to your home at around 4% reserve. However, it may still dip lower — this is normal and safe.

  • The last few percent are kept for the battery’s internal systems.

  • If the battery reaches 0%, it will attempt to recharge from the grid to recover its reserve.

  • This behaviour protects the cells and extends battery life.

Troubleshooting:

  • If your battery regularly drains to 0% and struggles to recover, check your tariff and charging schedule.

When to Contact Support:

If your battery frequently hits 0% and fails to recharge automatically.
