The 14.4V/14.8V 3200mAh 18650 Li-Ion Sweeper Battery powers Xiaomi, Haier, and Yunmi robot vacuums with high energy density, long runtime, and stable voltage output. Its 18650 cell design ensures durability and compatibility with models like Xiaomi Mop Pro Mijia 3C STYTJ02YM, Haier JX37, and Yunmi MVVO1-JG, making it ideal for maintaining cleaning efficiency.
Which Robot Vacuum Models Are Compatible with This Battery?
This battery is designed for Xiaomi Mop Pro Mijia 3C (STYTJ02YM), Haier JX37, Yunmi MVVO1-JG, and other vacuums using 14.4V/14.8V Li-Ion configurations. Always verify your device’s voltage and connector type before purchasing.
| Brand | Model | Voltage |
|---|---|---|
| Xiaomi | Mop Pro Mijia 3C | 14.4V |
| Haier | JX37 | 14.8V |
| Yunmi | MVVO1-JG | 14.4V |
How Long Does the Battery Last on a Single Charge?
Provides 90–120 minutes runtime, depending on vacuum mode. Charging takes 3–4 hours via a compatible charger.
Runtime varies based on cleaning intensity. For example, quiet modes typically extend usage to 120 minutes, while max suction modes reduce it to 90 minutes. Battery longevity also depends on environmental factors—carpeted floors demand 20% more power than hard surfaces. To maximize lifespan, avoid frequent full discharges and store the vacuum in moderate temperatures (15°C–25°C).
| Usage Scenario | Average Runtime |
|---|---|
| Hardwood Floors (Standard Mode) | 110–120 mins |
| Medium-Pile Carpet (Turbo Mode) | 90–100 mins |
| Post-Charge Storage (Idle) | 3% monthly discharge |
Why Does Voltage Matter for Robot Vacuum Batteries?
Incorrect voltage damages motors or sensors. The 14.4V/14.8V range matches OEM requirements, ensuring optimal suction and navigation.
Voltage directly impacts motor performance and sensor accuracy. A 14.8V battery delivers 2.7% higher suction power than 14.4V models, which is critical for deep-cleaning carpets. However, using a 14.8V battery in a 14.4V system risks overheating the motor coils. Conversely, lower voltage causes navigation errors due to insufficient power for LiDAR or camera systems. Always cross-check your vacuum’s specifications—most manufacturers print voltage requirements near the battery compartment.
What Safety Features Does This Li-Ion Battery Offer?
Includes multi-layered protection against overcurrent, short circuits, and overheating. The PCB ensures voltage stability, extending device lifespan.
How to Install the Battery in Xiaomi, Haier, or Yunmi Vacuums?
Power off the device, remove the old battery, align the new battery’s connectors, and secure it. Recalibrate the vacuum via its app if required.
