Makita offers 2.0Ah, 3.0Ah, 4.0Ah, 5.0Ah, and 6.0Ah battery varieties. One unique feature of the batteries is the ability to combine any two 18V LXT batteries to power a 36V tool.
For some of its pro-grade tools, Makita also offers the XGT battery system to provide a bit more power. The new XGT battery system is based on a 40V max battery.
These batteries come in 2.5Ah, 4.0Ah, and 5.0Ah amperages and can use the same charging system as the LXT. However, only about a third of Makita's products use the XGT system.
