Ego Battery, 7.5 Ah, Li-Ion BA4200T

Ran the mower for almost my entire lot, maybe 1/3 of an acre in total. Could have used another 5 mins. Grass was extremely overgrown though so that was my fault. With routine mowing 7.5AH will be plenty for my property. The gauge is great to have. Definitely recommend.

I've had my ego self propelled mower for 4 seasons. The battery had degraded some. But I have started cutting my 93 year old neighbors lawn this season. To be able to mow both yards, I couldn't use the self propelled. Now I can do both yards with self propelled.

Bought this 7.5 AH a month ago with a 5 AH. The 5 AH will do the front and back yard on a full charge. This 7.5 last a lot longer. So, if you are using the Self propelled mower, it makes it back to the shed under its own power. Great capacity, and the LED Power gauge ring is easy to see what is left of the capacity. Simple and efficient design.

I purchased a 7.5 Amp Hour Battery w/ Fuel Gauge to replace my original battery because it died. This updated version seems to have a longer run time. The fuel gauge is a vast improvement on the original unit because it shows how much power is still available. Well done Ego!

While I have other EGO tools this is my first battery powered mower. I am very happy with the purchase and love the operation, quality of cut and easy folding for storage. Due to the larger battery the mower is a little heavy when not using the self-propelled feature but it lasts the full hour of my cut as promised and I can see how much time is left on the battery gauge.

I've used this battery and also charged it. From a completely used battery it takes about 45 - 60 minutes to charge. I'm very happy with it. Placement of the fuel gauge is perfect! I am using it with a mower and you can easily monitor how may 'bars' you have left. Also, the last bar turns red to warn you it's about to run out. I like this.

I bought an 800 series mower and it came with this battery. I can mow the quarter acre lot beside the house and most of the quarter acre lot that house is on with one charge provided that I don't use the self propelled function. It charges reasonably fast, sorry I did not time it. So far I like the ego eco system.

Was not able to finish entire yard on a sngle charge. Less than 1/4 acre of grass, though because of grass length I had to mow several areas twice. Also most of the yard isn't level ground, so higher speed to get up hill and coasted down. Battery recharged quickly on fast charger. Really like the power meter indicator. Very visible.

I currently own eight ego tools, and therefore many batteries. While I love the tools, the battery performance has been very disappointing. It's uncanny how they seem to die just after the warranty runs out.

For a battery that the literature says could last up to 10 years or 1000 hours, my first one lasted less than 3.5 years and maybe 150 hours. Let's hope this one is better. Also, I don't look at EGo as a power equipment company. With the prices charged for underperforming batteries, it seems to me EGo is a battery company that also makes lawn equipment.
