DeWalt DCA2203C 20V MAX Battery Adapter Kit for 18V Tools

Using the DeWalt DCA2203C is easy. First, take the 18V - 20V MAX* adapter and attach it to your 18V tool. Then, insert one of the included DCB203 20V MAX* XR Lithium - Ion Batteries into the adapter. Make sure to use the 12V/20V MAX* charger provided to charge the batteries. Note that if you leave the battery in the adapter for a long time, it will drain. Also, always use 20V MAX* chargers with the adapter as it won't work with DEWALT 18V chargers. To keep your kit in good condition, store the batteries in a cool and dry place and avoid overcharging them.
