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.
Installation is genuinely simple: the battery drops directly into the YUKA Mini compartment and requires no extra tools. It is protected against temperature extremes, overcurrent, and overvoltage, and it carries FCC, UL, CE, and RoHS safety certifications for peace of mind.
The main drawback is compatibility: this battery works only with the YUKA Mini series, not with other Mammotion mowers. Also, because this is a newer aftermarket product, there are limited verified user reviews so far, although the warranty and 24-hour support reduce the risk.

Buying Guide: What to Look for in a Replacement Battery
Choosing the right battery for your robot mower involves more than just matching the voltage. Here are three key factors to consider before you buy.
Capacity and Runtime
The capacity, measured in milliamp‑hours (mAh) or watt‑hours (Wh), directly determines how long your mower can run on a single charge. A higher capacity means fewer interruptions and larger area coverage. Both PWRTank options offer significant upgrades over the standard battery, with the 7000Ah version providing extra runtime for bigger lawns.
Compatibility and Fit
Not every battery fits every mower model. The PWRTank replacements are specifically designed for the Mammotion YUKA Mini series (500, 600, 700, 700H, 800) and match the original connector and dimensions. They replace multiple factory part numbers (MWBT06S01P‑03, MWBT06S02P‑03, MWBT06S02P‑01, etc.) without any modifications. Installation is tool‑free, so you can swap the battery in minutes.
Safety and Certification
Lithium‑ion batteries can be dangerous if they lack proper protection. Look for certifications like FCC, UL, CE, and RoHS, which confirm the battery meets safety standards. Both PWRTank models include built‑in protection against temperature extremes, overcurrent, and overvoltage, safeguarding both the battery and your mower.

Final Thoughts
After reviewing both PWRTank batteries, we recommend the PWRTank 7000Ah Battery for Mammotion Robot Lawn for users who want the longest possible runtime and are willing to invest a bit more for extra capacity. For those who need a solid, reliable replacement at a lower cost, the 6000Ah Battery for Mammotion Robot Lawn Mower YUKA offers excellent performance and the same safety features. Both are easy to install, backed by a 360‑day warranty, and will breathe new life into your YUKA Mini.

Frequently Asked Questions
How long does it take to install a replacement battery on a Mammotion YUKA Mini?
Installation takes about five minutes with no tools required. Simply remove the old battery, plug in the new one, and secure the compartment. The mower will need a few charge cycles to recognize the full capacity.
Will a higher capacity battery damage my robot mower?
No, as long as the voltage matches (21.6V in this case). The mower’s charging system regulates the current, and the battery’s built‑in protection prevents overcharging. Both PWRTank batteries are designed to be safe drop‑in replacements.
Why does my new battery show less runtime initially?
Lithium‑ion batteries often need 3 to 5 full charge/discharge cycles to reach their maximum capacity. During the first few uses, the mower’s software calibrates to the new battery, so runtime will improve after those cycles.
Can I use these batteries with other Mammotion models?
These batteries are specifically designed for the YUKA Mini series only. For other mower models, check compatibility or look for dedicated replacements. For more battery tips, browse our best long lasting robot mower blades guide.
