56V POWER+ 4 Ah ARC Lithium-Ion Battery

Long lasting in my use to date. Light meter to advise capacity left as you sue the battery. Rather heavy so made the blower and the trimmer a bit unbalanced with the concentrated wait on one end. Neck strap solved that issue for the trimmer. Some may prefer the smaller and thus lighter battery but that may require you have a spare.

Authentic EGO battery, it appears EGO has discontinued the 4AH battery which retailed for $279, now being clearanced by 3rd party sellers for $144 here. It's the EGO battery, runs like a charm. To purchase a new 5AH battery is $329. I like to use the 4AH for the string trimmer and the blower, it's lighter than the 5AH and not a whole lot less power.

Bought this product because my old gas powered weed eater was heavy and finally broke. This battery works great with my new EGO electric weed eater, is light, easy to load, easy to charge, and had excellent ratings. I am happy with the purchase. Hopefully, it is a durable as advertised.

The battery came as a package promotion online. We already had the EGO 21" Self-Propelled Mower and was what convinced me to purchase these accessory lawn tools.

The batteries are easy to recharge and the fact that this 880 blower came with two batteries, it means that I can start and complete a cleanup, or snow removal, with one full charge! It's amazing to have received 2 batteries with this amazing blower!

I've been pleasantly surprised with this 10A replacement battery for my Ego mower. I previously used a 7.5A Ego battery that came with the mower, and this one gives me noticably longer mowing time. Even though a 10 amp should provide longer mowing time than a 7.5 amp, because this is a non OEM battery I would have been happy with equivalent run time. It charges very quickly on the same Ego charger. Will it last as long as an original Ego battery? Way too early to tell at only 10 cycles used, but at roughly 20% of the cost it's a gamble I'm very comfortable taking. My only complaint and the reason I don't give five stars is that it's incredibly hard to tell how much battery is left while using the mower. It's difficult to tell how many of the indicator lights are still green without stopping the mower and opening the battery cover. With my original battery the lights were bigger, brighter, and easy to view through the battery cover. I would still still purchase this battery again and strongly recommend it.

The original 4.0 amp-hour battery that came with the tool failed after two years of use. The battery would not take a charge. The battery was quickly replaced, and the replacement battery has been performing well. I have a number of EGO tools and am very happy with their efficiency and performance for the most part. The batteries on all of these tools last through each use without having to recharge. This makes them a great purchase and I would purchase again. I do have one issue I need your help with though. The bottom of the auto line feeder head on my string trimmer is wearing through. Is there a replacement part I can order for this?

This review gets a three because it's predecessor battery lasted only five years. Of course at that time it's out of warranty in your forced to either buy a new battery at exorbitant prices or just buy a whole new blower that comes with a battery. Overall, the previous blower and battery worked great until the battery died. I probably use the blower at least 4-5 times a week for yard, garage, shop, and other purposes. If the battery had lasted 7-8 years as suggested I would give the products five stars.

These battries are really very small for my snow blower, It's not even to clean half the driveway during snow strom. Had to charge 4 times to clean snow on my two garage driveway. After this bad experience I got 10. A batteries and they worked good. Same kind of work with single charge

I was disappointed upon opening my trimmer/blower kit that the battery was from September of 2024. This battery is already 17-18 months old. I used the blower after opening the box to blow off my driveway. I only ran the blower for 5 minutes (NOT using the turbo button) and it went one bar on the battery meter. I just charged the battery completely and plan on using it this week. I am hoping that the battery performs better after a full charge. I am in the market for a new lawnmower and am considering the Ego self-propelled 21" mower but am waiting to see how the current battery i have performs after the next use. I realize batteries don't last forever but given the cost I expect above average run time compared to your competitors.
