Welcome back Sparks Lawn.  Any additional details on how much the battery life is affected by the HL blade?  I have not done enough testing to conclude that battery life is shortened.

Not necessarily a problem as much as an observation with the high lift blade.

After extensive use on 4 ego 21" mowers Self propelled with 2 high lift and 2 standard blades, this is what i have noticed over the past week. 
THE GOOD 1. With all 4 blades being brand new, the high lift blade does, in my opinion, cut somewhat better. I usually cut at 4 setting as my customers like the look of the taller fuller lawns. Seems to leave less individual blades uncut as I experienced with the mulching blade. Blows out clippings noticeably better with side discharge chute with much less clogging, most likely due to the increase airflow pushing out. 

THE BAD 1. Louder. Not just louder but definitely causes the machine to go into "turbo" mode almost instantly possibly due to the increased resistance it notices. I made sure the decks were clean and even on a dry day regardless of which machine I put the HL blade on it simply revs up. Along with the higher RPM we also get two more issues...

2. Shaking/ Jittering. The higher RPMs means the blades with no resistance other than the blade itself causes the mower to feel as if the blade was off balance or the shaft was out of place. You get used to it but I am not sure if it will damage anything in the motor over the long run. 

3. Increased RPM = noticeable drop in battery life. Before with the 7.5 ah batteries I could run the mower 60-75 minutes continually no problem. With the HL blade Ive noticed it drops down to about 45 minutes, if that. Batteries are now constantly on the inverter /charger to get through the day.  Even my guys have noticed the drop as we had begun to swap batteries more and more often as the week progressed. 

In short, if you want a better cut, don't mind less battery life and are confident in your ego warranty, I say go for it. At least have it on hand to swap with the mulch blade. If you have a larger yard and are used to doing everything in one single charge, you may be in for a surprise.

Interesting feedback.  I adapted (chopped down) an AB2101 blade to work on my 20" Gen 1 mower with the 5.0 battery.  Have not noticed that it jumps into turbo mode all the time (only when I hit a tough spot).  Also didn't think it was much louder between the two blades.  I did noticed about a 3 dBA (measured on an iPhone) increase when bagging over mulching (expected).  The run times do seem to indicate a higher load on the motors and batteries.

I also have used a HL blade, and did not notice the mower going into turbo mode or extra vibrations. Have you checked your HL blade for balance? (I sharpened mine immediately upon receipt, and balanced it as part of that process, so I don't know how well balanced it was straight from the factory.)

Yeah, I'd check the new blade for balance, given what you just reported.  Reduction in battery life sounds about right, per what I was told by Ego (Jen).

I don't believe my mower has gone into turbo mode, not sure it has ever gone into turbo mode, but i have only used it maybe 6 times.  The last two with the HL blade.

Me too. Have not noticed those things happening to me. *possibly* shorter battery run time but no turbo and huge cutting and suction performance.

Not noticing any impact on battery life, but I have done any scientific studies on it.   just seems like I don't recharge the battery any more often than w/o the HL blade.  There is a bit more noise as it's moving more air, so what can you expect?  :)   And, it actually WORKS to lift stuff, and grass, off of the lawn.  glad I spent $25 on the blade.

I've been using the high-lift blade for the past 2 months and I have noticed no decreased battery life or any other negative effects. Just a cleaner, neater lawn!!

Ditto that. It removed.my only complaint about this mower.
