Choose a jigsaw without battery if you already have a matching battery. You won't have to buy a sawing machine with battery and battery charger. This not only saves you money, but also space in your shed or workshop. For example, you can also use the 18V Makita LXT battery of your drill on your jigsaw without battery. This makes it very appealing to go for bare tools instead of a complete set when buying new tools. Useful for you and much more sustainable than adding another new battery to your tool collection.
