The DC18RD Dual port charger is capable of charging two Makita 18V batteries, simultaneously, and it will recharge both in the same time as with their actively cooled rapid charger. The range of Makita machines utilising two 18v Lithium-Ion batteries to generate a mighty 36v of power is expanding quickly. Therefore the new twin-port fast charger that takes just 22 minutes to fully charge two 18v 3.0Ah batteries will prove invaluable. This new twin-port charger will charge two 4.0Ah batteries in 36 minutes. With an LED charging display, and full charge audible alert, the Makita DC18RD fast charger has a forced cooling system for battery protection and a built-in electronic current limiter for overload protection.
