The battery held its charge well, and the vacuum stayed powered for the full cleaning time I needed.
Key Features in Action
One thing I really appreciated was the 14.4V power and 3000mAh capacity. This gave me enough runtime to clean my whole apartment without recharging. The lithium-ion type means the battery charges quickly and lasts longer, which is important for me since I use the vacuum daily. Also, knowing this battery is designed specifically for my Shark ion vacuum models made me feel it was a safe and perfect fit. The 2-prong connector is simple but crucial, and I’m glad I checked before buying.
Long-Term Performance
After using the KUNLUN battery for a few weeks, I can say it’s been dependable and consistent. The vacuum’s performance hasn’t dropped, and the battery still holds a full charge like when I first installed it. It’s nice to have a replacement that feels just as good as the original without paying a high price. I’m confident this battery will keep my Shark vacuum running strong for a long time.
