    • Purchased as spares
Dislikes: none Likes: charge fast using the Hatt 20V4Ah charger.(these will charge on the Hart 20V2Ah charger, but take a lot longer to reach full charge). Also like they have 4 bkue L.E.D. bulbs that indicate how much battery powet is left in the battery, all 4 lit = 4 hours, 3 lit = 3 hours, 2 lit = 2 hours, 1 lit = 1 hour or less. At least from my use of these batteries, this seems to be very consistent. When Charging as the battery reaches its full charge these 4 bulbs will turn on to show what power level the battery is currently at, when it reaches its full charge, all these bulbs are turned off and charging stops. There is a small square, blue button next to the bulbs, just press it in and it will show you exactly how much power is left in the battery, a very useful feature, my original 20V2Ah battery doesn't have this feature, I wish it did! I charged my batteries when I received them to full charge, that's been around 2+ months, they have been sitting on a shelf since this charge, pressed the button to verify charge status, all 4 bulbs lit up bright blue, so they hold a charge for quite some time while being stored for future use. Excellent batteries, work well, last longer, and holds charges longer, highly recommend these for your 20V battery powered Hart Tools. ... show more

    • Shorter battery Life
These have definitely made mowing easier as I can just pop the used battery on to charge while I’m mowing with the other but I thought the battery would last longer.

    • Work great!!
The little battery that came with my blower didn't last for many seasons before it started giving out on me after only a few minutes. These batteries provide long lasting power to get all of my lawn clippings taken care of without worry. Highly recommend!!

    • Doesn't last long
The battery does work well while it's charged, but it doesn't last nearly long enough to get the job done.
