Our Testing Experience
First Impressions
When I first received the FirstPower 3.2Ah RVBAT850 battery, I was eager to try it out. The battery arrived quickly and was exactly the size I expected—compact and lightweight at 2.0 x 2.6 x 4.0 inches. I double-checked to make sure it was the 2-prong connector version since my Shark Ion R75 vacuum uses that type. Installation was simple and straightforward; the battery fit perfectly into my vacuum without any forcing or adjustments. Right away, I felt confident this was a solid replacement for my old battery.
Daily Use
Using the vacuum daily with the FirstPower battery was a smooth experience. I noticed the vacuum ran for a good long time on a full charge—much longer than my previous battery. It comfortably handled cleaning my entire apartment without losing much power. The vacuum stayed strong and consistent, which made my cleaning sessions quicker and less frustrating. I also appreciated that the battery didn’t heat up noticeably, which sometimes happens with older batteries.
Key Features in Action
One of the best features I found was the upgraded 3.2Ah capacity. This gave my vacuum a longer runtime—typically between 120 to 180 minutes on a full charge, which is great for bigger jobs. The battery’s lithium technology means it charges faster and holds power better than my original one. Also, since it’s designed specifically for Shark models with a 2-prong connector, I didn’t worry about compatibility issues. The fit and function were spot on, so I could just swap the battery and get back to cleaning without any hassle.
Long-Term Performance
After using the FirstPower battery for several weeks, I can say it has held up really well. The runtime has remained consistent, and I haven’t noticed any drop in power or performance. Charging times stayed quick, and the battery didn’t show any signs of wear or overheating. Overall, it feels like a reliable upgrade that will keep my Shark vacuum running smoothly for a long time. I’m happy I chose this battery replacement and would recommend it to anyone needing a compatible, long-lasting option for their Shark vacuum.
