Works great
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.

Superior Battery vs.the Competition
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

    2 pack 20v batteries
    We purchased a Drimel tool from Walmart. We got to use it all of 2 times and something happened causing the battery to leak out and it ruin the drimel and the battery. I went a bought the 2 pack batteries and tried the dremil with a new battery and still it would not work. A bit bummed but I still have a drill that I can are use of the batteries with. I think the drimel tool we got was bad possibly? It was stored indoors ao it wasn't from the heat. No clue. But hey, Drills still work

    Awesome for backup reliability!!
    I bought these a week or so ago to have extra power on hand and I am grateful that I did. I was working on a job and ran out of juice but luckily I had my 2 backup batteries which saved me from having to wait on a battery to recharge!

    Longer battery life
    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.

    Works with all HART 20-Volt Tools
    The HART 20V 4.0Ah Lithium-ion Battery will work will all of the compatible 20 volt HART Tools. You will need to purchase the Charger and Tools separately. The battery weighs 22.25 ounces, which in my opinion is not heavy. It measures approximately 4” x 3” x 2.5”. It took a little over two hours to get a full charge after receiving it. There is a convenient on-board fuel gauge, press the button and the four available lights will illuminate blue. Full charge is 4 lights. The button is easy to get to weather it is installed on our tool or not. So far we used it on and off for a little over an hour and it has sat for a week in the garage and it still shows it has a full charge (4 blue lights).

    Small Powerful Battery
    The Battery charges very fast. The button on the side will let you know how much charge is in the battery. Very useful to see if there is enough power before you start a job. The battery is also able to leave on the charger with the latest technology. Built solid and easy to use.

    Long life and quick charge
    The HART 20V 4.0Ah Lithium-Ion battery us a universal battery that is compatible with all HART 20V power tools. The battery is lightweight and compact. The HART 20V 4.0 Ah battery is there to provide the power you need when you need it with 4x longer runtime than the HART 20V 1.5 Ah Lithium-Ion battery. Since Hart tools are sold without a battery, this is a must have. I am impressed with the speed of renewing to full charge and the long life while in use.

It has a very long battery life. It is perfect for all Hart 20V system tools. I definitely recommend.
