Can I use a 20v battery in a 12v Dewalt drill?

Unfortunately, no. The 12 volt Dewalt drill will require a 12 volt battery. It may seem like a larger battery (voltage-wise) should be able to power a smaller voltage tool. This is not the case. The 20-volt battery pack is too large to fit in the 12-volt tool. The 20 volt and 12 volt batteries are two different sizes.

Are Dewalt batteries made in China?

No. Dewalt has manufacturing facilities in Maryland, North Carolina, South Carolina, Tennessee, Kentucky, and Connecticut. Authentic Dewalt batteries will be assembled in the US. However, inside a Dewalt battery come a number of smaller battery cells and electronic components linked together. The ‘guts’ of the battery may originate from other countries. So it’s possible components inside the battery came from China as well as other countries.

Can I use a 20v battery in a 12v Dewalt drill instead of 12v battery?

Similar to the answer to the first question, a 20 volt Dewalt battery and a 12 volt Dewalt battery are two different sizes. The batteries of one size will not physically fit into the tool of the other voltage.

Does a higher Ah battery give more power?

Yes. A higher Amperage hour (ah) battery generates more power. The DCB124 is 3ah and will have a bit more kick than the DCB127, which is a 2ah battery.
