The DC18RC are most likely to charged the BL1830 battery, which is the most popular of 18V Makita power tools. It is a Li-ion battery.And the DC18RC battery charger has two volt 110 Volt and 240 Volt. The 240 Volt DC18RC charger can replace model DC18RA & DC18SD because of its improved performance and full compatibility with Makita's NEW
'Star' labelled batteries that communicate between the tool, battery & charger. And, it is a fast charger.It can charge a Makita BL1830 Battery
in approx 22 minutes.But, I do not recommend to convert a makita charger model DC18RC at 110 volt to 240 volts.The reason is as below:1. This will void product warranty ! If you follow this mod, you do it on your own risk
! 2. There are several comments that describedsame model # but with different design and components. Please beware that this mod might not work on your chargeror worst, will damage it. Only perform this mod if you know your way around with electronics !
