My model of tineco vacuum mop are comprised of 6 pieces of 21700 batteries, each piece of 21700 battery should output around 3.7V. Use a multimeter to measure each of the cell to identify the bad battery cell. If certain battery cell has voltage far below the 3.7V, that’s mean that particular battery cell is faulty.
The 21700 battery is a cylindrical lithium-ion battery with a diameter of 21mm and a length of 70mm. It offers a nominal voltage of 3.7V and a capacity of up to 5,000mAh, making it a powerful and efficient energy source. Its energy density ranges between 250 Wh/kg and 300 Wh/kg, depending on the chemistry.
Removing Tineco Vacuum Mop Battery Step 1: To start process, first it is important to remove the cover and to rotate display of the Tineco vacuum mop to do that. As you can see from the image above, I rotated the display cover clockwise and it could be removed easily.
It has a nominal voltage of 3.6V to 3.7V and is increasingly popular for its higher capacity, making it ideal for high-drain devices like flashlights. With a capacity ranging from 3000mAh to 5100mAh, the 21700 battery offers up to 42% more capacity than the 18650 battery.
Energy density: The 21700 batteries have an energy density ranging from 250 Wh/kg to 300 Wh/kg. Size and weight: The battery's dimensions are 70 mm in length and 21 mm in diameter3. The weight typically ranges from 50 to 70 grams. Voltage: The voltage of a 21700 battery typically varies between 3.6V to 3.7V when it’s in use.
The 21700 cell stands out due to its standardized dimensions of 21mm in diameter and 70mm in length. These measurements make it larger than the widely used 18650 cell, which measures 18mm by 65mm. This increase in size allows the 21700 to deliver higher energy storage and improved performance.
