Wasn't sure a third-party battery would hold up, but this one actually runs the full 180 minutes on a single charge like it says. Installation took me maybe five minutes with a screwdriver. My robot's back to doing the whole downstairs without stopping to recharge.

My old battery was dying after about 20 minutes, and now this one runs the full 180 minutes on my main floor without needing a recharge. Installing it took maybe two minutes, the connector clicked right in. Nice to have the vacuum actually finish a whole run again.

The 5200mAh capacity is exactly what the listing promised—my vacuum is running the full 180 minutes again, which is a huge relief. Installation took me less than five minutes with the included tools, and it fits perfectly in the X8.
