Great improvement on an already awesome battery
Battery has awesome power and long runtime. Love the new “fuel gauge “ so I can see how much useful battery life is left

7.5 Amp Hour Battery
Powerful battery that is long lasting. Charges up from new in about 1hr in Rapid Charger. Battery has some weight to it, so if possible use with shoulder strap on tools if available.
Power for days 7.5AH
Came standard with a EVO 21" select cut more that was purchased for Father's Day provides more than enough power to get job

4 star review
I do like the fact we can purchase the item in the store the 4 star comes in because we want a second battery if we need additional runtime on a Saturday but the item is shipped, perhaps the next ego battery would have an extreme 21.7 amps 56v charge it once a week

Well engineered and easily adjustable
With 16" of snow today on top of what was already there, it might be JULY before I get to use this! The attached photo shows a screw that was loose in the box but I cannot see where one is missing from the machine. Any ideas?

Super Power
I've always had two other brands of electric mowers but none of their batteries packs as much smooth and consistent power as my 7.5 Amp hour EGO. I finish my front and large back lawns with power to spare.

Will never go back to fossil fuels
Got four mowing seasons using two batteries and one battery is still good. One battery came with the mower but I got a second battery right away. The battery that came with the mower was manufactured in Feb 2016. It only runs the lawn mower for about 14 minutes so I discarded it. The second battery was manufactured in Nov 2014 and it still runs the lawn mower for 51 minutes. So this new battery replaces the one I discarded so I still have two batteries so I can keep on mowing while the other battery recharges. The original mower was scraped and I got a replacement mower which was received 10-17-2019. This third new battery was manufactured in July 2020. Besides the lawn mower I have a string trimmer and a 150 Watt power inverter.
