My gutter installers here run Dewalt and have a couple extra batteries for each driver and 3 or 4 chargers lined up in the trailer. It really depends how they are used. The landscapers would go through batteries pretty quick. Most of the tools are constantly running not like the gutter guys running in some metal screws. My Worx lawn tools are 20 volt. The standard batteries are 2.0 a/h and are light and handy for trimming bushes or at the end of the pole saw as long as I don't need it too long. I have a big 4.0 a/h battery that lasts a very long time on the leaf blower or string trimmer. A couple chargers keeps them ready to go. Likewise, drills always take more battery than a impact tool.
