I have two 56V 1400BA 2.5AH batteries that came with my EGO blower and leaf trimmer. After 2 years of light duty they won't power either piece of equipment for more than 15 minutes. Anyone else have an issue with the longevity of these batteries. Bought in October 2017.
How long of runtime do you think you were getting before for each tool? 15 minutes sounds about right for the leaf blower depending on how fast you are running it. Thinking you meant string trimmer where you wrote leaf trimmer? If so, that timing also seems about right depending on how fast you are running the trimmer too.
