This was a great replacement battery for my Shark robot vacuum. My vacuum is an older model, so the original battery just wasn’t holding a charge like it used to. I was happy to find a compatible replacement. It installed easily—just popped right in—and started working right away. It charges without any issues and has brought the vacuum back to life. Overall, a simple and effective fix that saved me from having to replace the entire unit.

I picked up this Futurebatt replacement for my Shark UR1100, and even though that specific model isn’t listed in the compatibility notes, it fit perfectly as it also takes the RVBAT850 battery. Replacing the old battery was straightforward and only took a few minutes. As an engineer, I took the "5000mAh" claim with a massive grain of salt because these rarely live up to their claims....and I was right to do so. It certainly didn't double my vacuum's runtime or turn it into a marathon cleaner. In actual use, the battery performs about the same as a brand-new OEM RVBAT850 battery. While that might sound disappointing given the labeling, it is actually much better than most of the cheap knockoffs I have tested in the past that usually die after twenty minutes. It provides a consistent 14.4V output, which keeps the suction strong throughout the entire cleaning cycle. It also came with a few extras, like a screwdriver and a cleaning tool with a small blade for cutting hair off the brush roll, which was a nice touch for the price. For around twenty dollars, this is a great way to revive a vacuum that can no longer make it back to its dock on a single charge. It seems to be a reliable, well-built lithium-ion pack that follows the standard manufacturing protections against overheating and overcharging. I’m very happy with the purchase, and it's a great bang for the buck, matching the OEM battery's performance at less than half the cost. Just don't expect it to double your runtime.

I like my shark vacuum but I wanted more battery life for it. Increased battery capacity allows the vacuum to run longer and it allows it to run at the highest level for longer. Battery voltage drops off from max rating based on the capacity, higher capacities will not dramatically increase the power, just allow the device to run at the higher power setting for longer. With this new battery my vacuum can now get to all my rooms without recharging. I used this to replace the provided battery with a shark matrix robot vacuum. It takes maybe two minutes to swap out the battery. This kit came with a nice brush and cutter to clean out the vacuum of debris and the screw driver needed to do all the work. Once installed, I placed the vacuum on the stand and it started charging, the next morning it worked flawlessly and finished all the rooms. Info Very easy upgrade Much more capacity Worked with shark matrix 2 prong.
