Awesome!
HART 40-Volt 4.0Ah Battery Accessory, Lithium-Ion, On-Board Fuel Gauge... Awesome battery. I can get hours of work done using this... My blower uses 2 batteries and it is awesome to switch from one to the other and continue the work.. Makes the job so much easier. And I can switch the battery from one tool to the next seamlessly. I love the on board fuel gauge, just a small push of a small button lets me know how long till it needs a charge... Plenty of power and battery length..... I couldn't be more pleased. .. This battery gets 2 thumbs up review !! We received this product from the Spark Reviewer program.

    It sometimes pays to send in warranty papers.
    Ordered battery when 20 month old battery would not charge. Was shipped from warehouse, since was not stocked in store. New battery arrived one day after promised, and would not charge. Got new charger from Walmart and still would not charge. Went back to Walmart with three chargers and two batteries that would not charge, spending one hour at customer service and they couldn’t figure out why. They called Hart product manager from back of store to help, and that person did not show up after waiting 25 minutes. Went home and called manufacturer in South Carolina. After being placed on hold for 39 minutes due to unexpected high call volume, I got a human to answer. He found that battery shipped me from warehouse was over three years old , and my original battery was still under warranty. He sent me two new batteries, which arrived in two days and both work well. Got refund for charger I had bought from Walmart, since old charger works. Took a while to get it fixed, but staying pleasant to employees finally paid off. Certainly expect batteries that cost $137.00 should last over three years. Opinion of battery will improve if new batteries work over three years.

    Hart 40 Volt 4.0 Ah Battery Performs Nicely
    The Hart 40 volt , 4.0 Ah battery performed like a champ. Two hours to charge from the factory, installed it into the Hart push mower and ,I was able to mow the entire lawn with power to spare .A 45 x 125 city lot (small house, small garage)a lot of grass. I set the mower to cut the minimum, the grass was long and some areas with the long wild grass that ,I cut in short swipes to eliminate hogging. I am extremely pleased with the performance and pleasantly surprised.

    Excellent
    We used this on our HART weed eater. Was able to weed around our large house and different areas around our land (2 acres). The battery lasted the entire time. The battery capacity is pretty easy to read and a great feature. The gauge takes the guess work out of how much time you have left on the battery.

    Great for yard work without the wires
    Works well with my wireless Leaf blower and the charge last much longer than the other 4.0 Was able to handle my whole 2 acres of leaves after a major storm hit us very recently so clean up was a lot easier without needing to run back inside for a charge.

    Works great
    I received the Hart 40 volt battery and it works on all my Hart tools. Now that I have an additional battery I can do my yard work in a short period of time. I like having the on board fuel gage because just pushing the button it tells you how much battery you have left. I recommend this to anyone who uses Hart products.

    Powerhouse of a battery
    Hart 4Ah 40V Lithium Ion Battery The Hart 4Ah 40V Lithium Ion Battery is a powerhouse. It holds a charge for a very long time. It is easy to recharge. You put it in a docking station and plug it in a 110 volt electrical outlet. The docking station comes with a Hart tool such as a mower, blower, trimmer, or edger. The battery is easy to install. It fits well onto multiple tools that are made by Hart. The battery is heavy enough that it helps distribute the weight of the tool it's installed on. It is a well engineered battery. This battery powers tools that increase the joy of mowing, blowing, and trimming without the noise of gas machines or dragging around electrical cords. I have an edger by Hart and am looking forward to getting the Hart blower and Hart trimmer that this battery can attach to. It also fits a mower. The whole system that the Hart 4Ah 40V Lithium Ion Battery works on is well engineered by Hart. It even lets you know when the battery is running low with it's onboard gauge.
