    • Typical EGO quality, particularly useful for the chainsaw.
Style: 4.0 Ah Battery
I haven't done any real testing, but it seems to last about twice as long as our 2 and 2.5Ah batteries, as expected. The battery charge level 'meter' (ring of LEDs) is helpful. Better than the older batteries that are only green or red. Needless to say, it is about twice the weight of the 2Ah batteries, which is noticeable. I would not want to use a larger battery if the tool will be carried for any length of time. ... show more

I own several Eco power batteries from 2.5 amp hour to 6 amp hour. I use them a lot on multiple pieces of equipment. Like most Ego Power products, the battery is well designed, well made, and performs as expected. Batteries recharge quickly, last the expected amount of time depending on use, and have a quality that reassures one of avoiding common battery hazards associated with cheaper brands. ... show more

    • Run time is still quite good.
Style: 4.0 Ah Battery
Seems to work as well and run as long as the OEM battery even though it only 4 Amp capacity instead of 5 Amp. We bought this lower capacity replacement because the price was considerably lower.

Style: 4.0 Ah Battery
It seems this 4A battery is far short of running time compared to the original 5A battery.

    • Good Battery

It is a battery. This battery is hefty so I’d use it in a mower and not a leaf blower or trimmer.

    • NOT WORTH THE COST!
Style: 4.0 Ah Battery
Review Image by HS
These batteries are absolutely useless on my snow blower! I really regret buying the entire system, it's NOT worth the cost. I bought two of ego power+ 56v 4ah batteries about a year ago along with ego 24in 2-stage snow blower and dual charger. When my old gas powered snow blower started to crap out on me, I'd figure i would invest in something eco friendly. Unfortunately I didn't find out how bad these batteries are until I started to use them this winter. Well long story short, it takes over an hour to charge but only last 15 minutes, and with lowest power settings. If I try to use turbo setting, it would get over heated and shut down immediately. Normally taking 2-3 hours to clear my sidewalk and driveways now take 3 days! Worst part is when I called for help, they just told me "too bad, you bought the wrong batteries". ... show more

Was sent as a replacement for a dead battery out of the box. Seller wouldn’t replace it but Amazon stepped up.
