I actually got a lot more runtime yesterday. I dropped the power to the "low" setting and nearly trimmed and edged my whole yard and had some battery left for the blower. That's over 80' of sidewalk (both sides), 120' or curb, about 65 feet of flower beds and a 40' long driveway. It was a deep edging too as I haven't mowed in almost three weeks so it was over due for a deep hard cut edging. And the runner roots in St Augistine grass are ridiculously tough so it took a beating for sure.
