Don't let losing power keep you from getting the job done! This set of two 18V 4.0AH Lithium Ion batteries and 240V charger will keep your Makita tools running. The high energy cells mean more power with less weight, while the 16 contact terminals will give you consistent power and strong hold in all working conditions. The large release button makes it simple to change battery packs and you can easily monitor battery charge with the integrated LED level indicator. Avoid overheating with in-built air vents that evenly cool the cells while blocking damaging debris. This charger and set of two battery packs are compatible with all Makita 18V LXT tools, not including those with a black base and no star.
