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).

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.

Powerful

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.
