I am very impressed with the 6 different 20V HART cordless tools that I own. I bought this for the 6 1/2 inch circular saw I recently purchased. I love HART cordless tools so much, I plan on buying additional tools that I can use with this higher Ah battery, like the leaf blower and power scrubber, and the floor vacuum.

walmart.com

I am well pleased with this battery as I have been with all of the Hart tools. I have the full kit of the power tools and have been using them almost daily. They all perform very well

Quality tools

Great price, was less than the in-store pricing,

Hart is an underrated company I run side by side with my coworker who use's Dewalt and I get the same results!

the product works very well, the batteries last , but i wish the Wal-mart stores would sell the batteries at the store as you need a replacement when the other battery is charging.

hart vacuum is outstanding work very well .

[This review was collected as part of a promotion.] I love the bigger battery as it last longer then the original 1.5. Mostly using the bigger battery on the small items to the radio, fan and the USB adapter to charge my phone. Many uses on this battery and also hater to have more.

Longer battery life

harttools.com

[This review was collected as part of a promotion.] I bought this in Dec 23' and it's impressed me how much longer (and stronger) my cordless tools work now.  The 2AH batteries that were supplied with the product would last less than 15 seconds with my leaf blower, these are easily lasting 5-10 minutes on a high power consuming device like a leaf blower.  It lasts even longer with my weedwacker.   4AH is perfect for the higher power devices.

Lasts MUCH longer!!  Displays current power levels

[This review was collected as part of a promotion.] This batteries works perfectly with my hart circular saw. It doesn't comes with the saw, you need to buy it separate, which makes no sense to me. It should come with the saw.

Anyway It changes fast with the hart charger, it charges in about an hour and last for hours. It makes doing projects easy.

Works great

[This review was collected as part of a promotion.] I'm an INDUSTRIAL HEAVY EQUIPMENT(644kfront end loaders/D3Dozers/Tugboat Vessels/AmericanCranes,etc.)REPAIR AND MAINTENANCE TECHNICIAN for a Southern Port  and Terminal Company serving Global shipping vessels along with Locomotives at the very same plant. We store Bulk material from GYPSUM ROCK TO ETIMINE USED IN the production of touch screen glass. I have five batteries at work for 3 tools of the Competitor with Snap-on and Matco because THEY JUST DON'T LAST! When you compare it to Hart's most basic battery it's laughable and not even close. So....... now that I've got a 9-piece cordless collection just for home projects, I know that I'm going to replace ALL MY CORDLESS WORK TOOLS WITH HART "QUALITY" TOOLS

Superior Battery vs.the Competition

Power drain quickly. Used for 2 weeks and used with power drill does not have sufficient power to finish job.
