I have two 56v, 7.5AH lithium ion batteries that are about four years old. I’m getting about 15 to 20 minutes a charge blowing leaves - no turbo. Is this what I should expect?

The blowers are simply battery depleting devices. 15-2o minutes on high but not turbo is pretty good.

7.5AH batteries?...No, that seems short for 7.5AH batteries...:(

Another person recently had a similar question and this EGO chart was posted as a response, based on a 5 Ah battery and the 580 CFM blower.

I've never gotten that kind of battery life.. Even with new batteries.  It's been 20 minutes on average.  Then again my battery inventory is about 4 years old now.

Wouldn't be the first time a manufacturer was, umm, optimistic about battery life.

Paul, which blower are you using and at what temperature?

530 with 5Ah...I get 20 minutes with quite a bit of turbo...that's why I'm surprised by the 7.5Ah times

FYI, the only way to test battery life on the blowers is to actually test it. That means pick a speed setting from the manual, tape the trigger on, and actually time it.

Since Ego’s blowers are quite powerful, this also means securing them somehow so they don’t blow themselves away! ;-)

The 7.5Ah batteries have been on the market for a little over three years, so your batteries might still be under warranty. I would check ASAP.

This question just came to mind: Is the 3 year warranty for the batteries transferable or only covers the original owner?

Only the original purchaser.
