Descriptions:

【Non-Charging Function】:
Please note that this adapter does not support charging functions for DeWalt batteries.

【Compatibility Insights】: For an impeccable fit and performance, this adapter is compatible with DeWalt 20V MAX batteries. It is not suitable for use with older Milwaukee V-18 Ni-CD tools, nor is it compatible with batteries from Porter Cable or B&D.

【Distinguishing Between 18V and 20V】: Differentiating between 18V and 20V MAX batteries is essential. Most 18V or 20V MAX battery packs consist of the same configuration of 5 "18650" or "21700" cells in series or in multiple layers. The standard voltage of a single cell is approximately DC 3.6V. When these cells are connected in series, the voltage adds up; for example, 5x 3.6V = 18V. Similarly, the maximum power voltage for a single cell is 4.2V, and when connected in series, 5x 4.2V = 21V. In conclusion, whether it's labeled 18V or 20V MAX, these battery packs are composed of the same cell configurations, with no actual difference. The voltage designation varies based on branding preferences.
