This battery boasts a 7000mAh capacity and 21.6V voltage, delivering reliable power for extended mowing sessions.

The PWRTank 6000mAh replacement battery is purpose-built for Mammotion YUKA Mini robot mowers, including the 500, 600, 700, 700H, and 800 models. It is a direct replacement for MWBT06S01P-03, MWBT06S02P-03, and MWBT06S02P-01 battery modules, so owners can restore their mower without buying a new unit.
With a 21.6V, 6000mAh, and 129.6Wh lithium-ion construction, this battery offers higher energy density and extended cutting time compared to a worn original. Note that the mower may need 3 to 5 charge cycles before it recognizes the full capacity and delivers maximum runtime, so don't judge performance on the first day.

Buying Guide
Capacity and Runtime
The battery capacity, measured in milliampere-hours (mAh), directly determines how long your mower can operate. Higher capacity means longer runtime between charges, which is essential for larger lawns or if your mower often works at the farthest edges of the property.
For the Mammotion YUKA Mini, consider a 7000mAh or 6000mAh option. The extra capacity reduces charging interruptions and extends overall mowing sessions. We recommend verifying your mower’s compatibility to ensure the new battery fits and functions properly.
Compatibility and Fit
Not all batteries work for every robot mower. Your chosen replacement must match the specific model number of your YUKA Mini, such as 500, 600, 700, or 800 series. Check the manufacturer’s list of compatible devices before purchasing.
Installing a battery that is not designed for your mower can cause poor performance or even damage. The PWRTank batteries are engineered for a direct replacement, requiring no extra tools. For other replacement components, explore our replacement parts section for more options.
