Makita BL1840B 18 V 4 Ah Li-ion Battery-Black

Product Information

Makita 18V Lithium-Ion batteries resist self-discharge so they’re ready for use even after long periods of storage. The Makita Rapid Optimum Charger (sold separately) is a smart-charging system that communicates with the battery during the charging process to monitor current, voltage and temperature. This advanced charging technology helps optimize battery life and deliver a faster charge. In addition, the Charger has a built-in fan to cool the battery for faster and more efficient charging, even in hot weather conditions. Makita 18V Lithium-Ion is the world’s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery

The new Makita 1.5Ah battery with a 22 minute fast charge time with a DC10SB charger or 50 minute standard charge time with a DC10WD charger DC18RD is a two port fast charger that is able to charge two Makita Li-ion batteries (14.4V-18V) at the same time, as fast as DC18RC charges one battery. The Li-ion range delivers 430% more working capacity during it's lifetime compared to Ni-Cad and is 40% Lighter than Ni-MH. The Li-ion has minimal depletion of power during use or in storage over it's lifetime. Battery delivers consistent power and run time in extreme temperatures, even in winter (-4°F/-20°C)Equipped with Star Protection Computer Controls™ to protect against overloading, over-discharging and over-heating Makita technology delivers category-leading charge time so the battery spends more time working and less time sitting on the charger (charger not included)

What’s the difference between OEM (Original Equipment Manufacture) batteries and aftermarket batteries?The 18V LXT® 4.0Ah battery (BL1840) is compatible only with Star Protection tools, indicated by the Star Symbol™ and/or Yellow Battery Receiver under the tool. The new Makita 2.0Ah battery with a 30 minute fast charge time with a DC10SB charger or 70 minute standard charge time with a DC10WD charger.

The Makita 18V LXT® Lithium-Ion battery charges faster and works longer than standard lithium-ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The Makita 4.0 Ah battery combines more run time (35% more run time per charge than the Makita BL1830 battery) with a category-leading charge time of only 40 minutes, so it spends more time working and less time sitting on the charger. For added convenience, it also features an L.E.D. charge level indicator to monitor battery charge. These batteries were discontinued in 2012 when Makita introduced the LXT line. The LXT batteries are based on Li-ion technology, which is more efficient and more powerful than NiCd technology. They are also smaller and lighter than the yellow connector batteries. Charge times: 14.4/18V 3.0Ah battery in 60 mins 18V 4.0Ah battery in 90 mins 18V 5.0Ah battery in 110 mins The yellow connector batteries were first introduced in 2004 and were the first 18V batteries available from Makita. They were based on NiCd technology, which is less efficient and less powerful than the Li-ion technology used in the LXT batteries. They were also larger and heavier than LXT ones. Charge times: 14.4/18V 3.0Ah battery in 22 mins 18V 4.0Ah battery in 36 mins 18V 5.0Ah battery in 45 minsCharge Times: 2 x 14.4/18V 3.0Ah Batteries in 22 mins 2 x 18V 4.0Ah Batteries in 36 mins 2 x 18V 5.0Ah Batteries in 45 mins
