Possible Causes
Battery not fully cycled, Aging cells, Firmware estimation error, Temperature affecting voltage reading
How to Fix / Troubleshooting
Safety first: Normal use only; no disassembly required for calibration.
- Calibrate battery: Fully charge the vacuum, then run it continuously in standard mode until it shuts off.
- Recharge fully: Charge back to 100% without interruption.
- Repeat cycle: Perform this full discharge/charge cycle 1–2 times to improve indicator accuracy.
- Replace battery if needed: If large jumps persist and runtime is short, replace the Battery Pack.
