Need a reliable, compact battery for your Makita 18V LXT cordless tools? The BL1820B is a great choice. This 2.0Ah battery gives you up to 50% more run time compared to the older 1.5Ah model, and it charges crazy fast – in about 25 minutes with a Makita Rapid Optimum Charger. It has a built-in LED fuel gauge so you always know how much juice is left. Works great in hot or cold weather (down to -4°F/-20°C) and resists losing charge when stored. A perfect extra or replacement battery for drills, drivers, saws, and more in the massive Makita 18V system.
