📊 How 4000mAh Translates to Real-World Usage
| Usage Scenario | Estimated Runtime per Full Charge |
|---|---|
| Standard mode (suction only) | ~35–45 minutes |
| Max mode (suction + water pump) | ~25–35 minutes |
| Eco mode (reduced power) | ~50–60 minutes |
| Mixed usage (typical household) | ~30–40 minutes |
Estimates based on typical floor washer power draw of 150–250W. Actual results may vary by device model and washing mode.
🔄 Cycle Life Explained
A “cycle” equals one full discharge followed by a full recharge. The ASOL 6S1P maintains ≥80% capacity after 500 cycles under standard test conditions (0.2C discharge, 0.5C charge at 25°C).
Partial charges do not consume full cycles — so topping up after each use actually extends the battery’s effective lifespan. With typical household usage (3–4 times per week), this translates to well over 2.5 years of reliable service.
