Frequently Asked Questions

Quick answers to common questions about this product.

What does the DEWALT DCA1820 adapter do?

The DCA1820 allows you to use DEWALT 20V MAX Lithium-Ion slide pack batteries with DEWALT 18V power tools. It bridges the two battery platforms so you don't have to buy duplicate tools or maintain two separate battery collections.

Does the DCA1820 work with all DEWALT 18V tools?

It works with most DEWALT 18V power tools, but not every model. DEWALT notes it is compatible with selected 20V MAX batteries and most 18V tools. Always verify your specific tool model before purchasing.

Do I need a special charger for this adapter?

The adapter itself does not charge batteries. You will need a DEWALT 20V MAX charger (sold separately) to charge the 20V MAX Lithium-Ion batteries you use with the adapter.

Does the DCA1820 come with a battery?

No. The DCA1820 is the adapter only. 20V MAX batteries, 18V tools, and chargers are all sold separately.

Can I use a 20V MAX battery on my 18V DEWALT drill with this?

Yes. Slide a compatible 20V MAX Lithium-Ion battery into the DCA1820 adapter, then attach the adapter to your 18V DEWALT drill or other supported 18V tool to power it.

Will using a 20V MAX battery damage my 18V tool?

No. DEWALT 20V MAX and 18V systems both operate at the same actual nominal voltage; 20V MAX is the maximum voltage rating. The DCA1820 is engineered by DEWALT to safely deliver this power to compatible 18V tools.

Is the DCA1820 genuine DEWALT?

Yes, the DCA1820 is a genuine DEWALT battery adapter designed and manufactured to work within the DEWALT tool and battery ecosystem.

Can this adapter be used with non-DEWALT batteries or tools?

No. The DCA1820 is designed specifically for the DEWALT platform — DEWALT 20V MAX slide pack batteries feeding DEWALT 18V tools. It is not intended for use with other brands.

Why buy a battery adapter instead of new 20V MAX tools?

If you already own quality 18V DEWALT tools that still perform well, the DCA1820 lets you keep using them while switching to the modern 20V MAX battery platform — saving significant money versus replacing your entire tool lineup.

How many batteries can I run per adapter?

One adapter holds one 20V MAX slide pack battery at a time. You can move a single adapter between tools, or buy multiple adapters to keep several 18V tools ready to run.
