You can buy that Ryobi power cutter in kits with additional batteries as well, for extra money of course.
FWIW, I only have the one battery in my Harbor Freight power cutter, but I only have to recharge it once every 2 months for as much as I use it. I use the tool a lot, but not everyday, and when I do use it, it's only for a few minutes at a time cutting up a box or two.
everything is expensive here. Buying from the US is a thing of the past these days, especially the postage costs.
