Good quality, Powerful but expensive

The battery is powerful. It works well and holds a charge very well. But it is on the expensive side compared to comparable batteries from other companies. I bought it because it works with the HART lawn mower, I already have, but if I were buying a replacement lawn mower, I would switch to a different brand that uses less expensive batteries.

EXTRA BATTERY FOR HART 40V 6AH ELECTRIC LAWNMOWER

I RECENTLY BOUGHT A HART SELF-PROPELLED ELECTRIC LAWNMOWER (40V,6AH) FOR MY HUSBAND BECAUSE HE SAID THAT OUR GAS POWERED SELF-PROPELLED LAWN MOWER (WHICH WORKS GOOD--7 YRS. OLD) WAS HARD (TO HEAVY) TO PUSH UP AND DOWN OUR FRONT LAWN HILL, NOW THAT HE IS GETTING OLDER. ACCORDING TO HIM, THE ELECTRIC LAWN MOWER THAT I BOUGHT FOR HIM ,IS A LOT EASIER ON HILLS AND A LOT LIGHTER TO PUSH--HE LOVES IT!!!!! HE SAYS THAT IT HAS A LOT OF POWER, ALSO. (MAKE SURE YOU BUY THE 40V, 6AH NOT THE 20V OR 4AH) IT DID COME WITH ONE 40V (LARGE) BATTERY AND CHARGER FOR IT , BUT THE BATTERY BEING FULLY CHARGED--ONLY MOWED FOR ABOUT 50 MINUTES (OUR LAWN TAKES 80 MINUTES TO MOW)--SO I PURCHASED THIS EXTRA 40V, 6AH BATTERY AND HE KEEPS BOTH OF THEM CHARGED FULLY BEFORE HE MOWS. THE SECOND BATTERY, BY ITSELF, WAS VERY EXPENSIVE. COMPARED TO THE REASONABLE PRICE OF THE LAWNMOWER AND CHARGER AND BATTERY PACKAGE TOGETHER, BUT WHAT ARE YOU GOING TO DO--MY HUSBAND SAYS THAT IT WAS WORTH THE COST OF THE SECOND BATTERY.

Great Run Time

I needed a backup battery for my lawn mower and this one works perfect. I can now mow multiple yards in one day without having to worry about running out of battery.
