With Makita LXT 18V tools, you use 1 battery for different tools. From drills and hammer drills to circular saws and jigsaws, they all work on the same LXT 18V battery. This way, you don't have to use different chargers and batteries anymore for your different tools. This saves you money and space in your shed. Make sure you have 1 or 2 extra batteries so you don't have to wait while it charges and you can keep on working. In addition, an LXT 18V battery also works on Makita garden tools with the same battery platform and voltage. This way, you don't only do jobs around the house, but your garden also stays neat.
