Exactly the right size for my Shark vacuum, higher amps, runs better, battery charge lasts longer
Shark battery, I picked this battery because it had a larger amp capacity, this is the third battery for the shark, the batterys last about a year and a half then they shut off before I get sweeping done, I like the shark and the batteries are inexpensive. I installed this battery, and the first time I ran it it almost overfilled the dirt canister because it seems like it was running much better it wouldn't bog down on carpets it just flew across the carpets and I have not found its limit on how long it will run before it dies, overall very satisfied with this battery. The old battery that I replaced was 2000mil amp hours and this new battery is 3500. If you're working in amp hours it's 2. for the old one, and 3.5 for this one, also when you have it apart at any time it's great to pull the little bearings off the beater bar and pull out any strings or hair stuck in them and maybe put a little oil on them,

It was compatible with my Shark Freestyle Navigator, fitting flawlessly into the unit.
I'm so glad I found the FirstPower 3.5Ah 10.8V battery. My old vacuum battery had lost its power, and I was on the verge of buying a whole new vacuum. This battery was the perfect solution. It was compatible with my Shark Freestyle Navigator, fitting flawlessly into the unit. Installation was quick and easy, and it charged up in no time. The most noticeable difference is the improved suction power and extended run time. I can now clean my entire house on a single charge without the vacuum dying halfway through. It feels like my vacuum is brand new again, and the extra power makes a huge difference on carpets. This battery is a fantastic, cost-effective replacement that has breathed new life into my vacuum.

Cheap but Lasts About Two Years
I've owned the Shark Navigator vacuum since 2015. In that time, I've had to replace the battery five times. This battery is a cheap alternative to buying a new vacuum; especially at the prices today for new cordless stick vacuums. Keep in mind, these batteries are cheap, but only work for about two years. If spending less than $30 every two years works for you, then press on and buy this battery pack. It's super easy to install in the Shark Navigator

Works, and it was a snap to install.
Work just like it was supposed to, just make sure you get the right one for your vacuum. It's easy to remove and check before you order. Simple to replace.
