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 Makita 18v 3.0Ah Lithium-Ion battery contains high energy density technology. Being Lithium-Ion, the BL1830B has no memory effect and is much lighter than other battery chemistries. 22 minute re-charge in DC18RC charger as well as battery capacity indicator LED's which show you how much power you have left at the touch of a button. Fits all Makita 18v LXT Li-Ion tools with Makita 'Star' technology so if your tool also has a 'Star' you can be assured of battery protection. 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. W hen new, these batteries require approx. 6 to 8 full charges to reach their optimum performance. 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 The new Makita 4.0Ah battery with a 60 minute fast charge time with a DC10SB charger or 130 minute standard charge time with a DC10WD charger.

Charge times: 14.4/18V 3.0Ah battery in 22 mins 18V 4.0Ah battery in 36 mins 18V 5.0Ah battery in 45 mins Built-in CPU - gathers information from the battery's memory chip to determine optimum charging method Compact and lightweight battery charger designed to charge slide type lithium-ion batteries BL1011B, BL1021B and BL1016B. A great advantage of Lithium Ion technology is that it provides the user with the possibility to charge the batteries anytime, without any need to wait for their complete power deployment. A great improvement compared to older technologies like Ni-Cad

The DC18RC is a compact size fast charger which charges Makita batteries from 14.4v to 18v. Only 22 minutes to fully charge a 3.0Ah Li-ion battery. The innovative computer controlled charging system provides optimum charge to each battery through the digital communication between charger and battery. The internal cooling fan keeps the battery temperature low for minimum charging time. BL1830B 3.0Ah Lithium-ion Batteries 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. Makita’s 18v & 14v batteries have a built in memory chip that records the battery usage history. While the battery is connected it will transmit the data to the charger 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. Charge 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
