What Is The Charge / Discharge Cycle Duty Rating For Ego's 2.0/2.5/5.0/7.5 Ah Batteries?

I am considering buying into the Ego Power+ handheld tool platform and am weighing the pros / cons of purchasing individual tool batteries vs. the large 28 Ah commercial backpack battery (BAX1501) in combination with the ADB1000 adapter.

One of the considerations impacting my decision is the expected charge / discharge cycle duty rating for each battery type. Ego has made this information terribly hard to track down, as no mention of it is made in either the product manual for either battery type or the actual product listings on the Ego or Home Depot websites.

I have authored a separate question / thread specific to the cycle duty rating of the 28 Ah Commercial-series backpack battery (BAX1501) so as not to muddy the waters, which can be found at the link below:

Thus, the below two questions are specific to the charge / discharge cycle duty rating of the individual 2.0/2.5/5.0/7.5 Ah batteries:

  1. What is Ego's official claim regarding the # of expected cycle/discharge cycles?
  2. What percentage of original battery capacity will remain at that point?
I've encountered a variety of conflicting data on the point to date in my own research, which I've summarized below:




All of the above data points prompts multiple questions in my mind:

  1. Has Ego moved away from the Samsung 25R cells rated for only 250 cycles that they were using as recently as two years ago?

  2. If not, have they somehow managed to otherwise improve the battery tech to the point that the individual batteries are now rated for 1,000 cycles instead of only 250?

  3. All signs point to the 28 Ah Commercial-series backpack battery being rated for somewhere around 1,000-1,200 cycles, as can be seen in my related thread I linked above. Is this battery using different technology or cells than the individual batteries, or is it the same?

Information on this topic that others may have obtained from either empirical evidence or their own research would be truly appreciated.

Not sure about the numbers but I can see how Egos technology and design - BMS, phase wrap, and arc - could increase the life of the Samsung cells

Now 250 to 1000 cycles ???
