HART 20-Volt 4.0Ah Lithium-Ion Battery (Charger Not Included)

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.

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.

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).

I am a garage duffer and am not a professional of any kind. I enjoy little projects that are easy and fun. Honestly, if I get frustrated with a tool I will quit using it. I have not had that experience with this battery. I like how quickly this battery charges. I also like that it has a safety feature that prevents it from charging if it is too hot. This battery holds a charge for several months after it is charged. So when I need to do a project I don't have to remember charge my battery a few hours before I start. Then when I am done I can immediately put it on my charger without waiting for it to cool off (and probably forgetting to charge it at all) so that it is ready the next time I need it. It works with all Hart battery-powered tools, but I have only used it for their circular saw. It works well on that and does not add a lot of weight or bulkiness to the overall tool. I would recommend this battery to anyone buying a Hart battery-powered power tool. It is reliable and of good quality.

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.

The HART 20-Volt Lithium-Ion 4.0Ah Battery with On-Board Fuel Gauge is one of the most powerful rechargeable batteries on the market. The On-Board fuel gauge or battery meter lets you see exactly how much battery level is left before needing to recharge. The really good thing about this battery is that it is compatible with all Hart 20V Power Tools so you can interchange the battery between tools with just a snap.

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.

The HART 20V 4.0Ah Lithium-Ion battery is an incredible product! This battery works with all HART 20V power tools and provides a good addition to the tool collection in general. It includes Lithium-Ion technology, which helps give you long-lasting power. You can easily go through your projects while utilizing this battery and not having to worry about replacing it. The battery itself is very lightweight and also compact. You can move it around without getting tired fast. No matter what task or project you have to complete, this battery is very helpful and a useful buy. It has 4x the runtime compared to other batteries and is definitely good to have. I highly recommend it.

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

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