The Dewalt DCA2203C 20V MAX Battery Adapter Kit for 18V Tools allows for use of 20V MAX batteries in most Dewalt 18V Tools. This adapter requires the use of 20V MAX Chargers – this will not fit in DEWALT 18V Chargers. This kit includes two 20V MAX XR Lithium-Ion batteries, and a 20V charger so you can be ready to convert immediately. Use with DCB201, DCB203, DCB203BT compact batteries. Do not use adapter with premium batteries (DCB200, DCB204, DCB204BT, DCB205) in 18V Compact drills DC970, DC759. Warning: The adapter is not compatible with all Dewalt tools. The 20V MAX Li-Ion Battery Pack Adapter for 18V NiCd tools is NOT COMPATIBLE with 18V Dewalt radios, 18V Dewalt nailers, DC020 or DC022 Worklights, nor the DCS370 Bandsaw. For the DC500 Vacuum, the DW074, and DW079 Rotary Lasers, the adapter is functional but the tools’ battery doors will not fully close.
