DEWALT tool, battery and charger date-code lookup

Read the manufacture year and week from the separate DEWALT date code, including battery and charger date-code prefixes.

Check a documented system

What’s on the rating plate?

DEWALT products bearing the documented YYYY-WW-XX date field; six-digit prefixes for batteries/chargers.

Use the separately marked date code for the supported tool family. A registration placeholder or a purchase date does not establish a manufacturing date.

Checks ENERGY STAR model records and searches manuals separately from the serial. Certification records do not establish this unit’s manufacture date.

Known product context (optional)

Choose a system only when it matches the product family and its documentation. A purchase year or a manual’s publication date does not establish a manufacturing date.

Where to find the numbers.

Find the complete serial and any separately labelled date, product or model code. Compare your device with the matching product family below.

Corded and cordless tools

Look for
Separate DATE CODE
Label location
The unique serial is generally on the rating label or inside the battery compartment. Look for the date code separately, molded or engraved in the housing.
Format / what to enter
YYYY-WW-XX, for example 2017-22-59.

The model is a separate D-prefixed marking on the rating label. Tool kit/battery suffixes are not encoded by the date field.

Battery packs

Look for
Battery DATE CODE
Label location
The date code is generally printed on the battery plastic near the charging contacts/cells.
Format / what to enter
First six digits YYYYWW; a longer printed suffix may follow.

The DCB-prefixed battery model is printed separately.

Chargers

Look for
Charger DATE CODE
Label location
Read the date-code marking on the charger housing; the manufacturer guide illustrates the label area and underside/back of chargers.
Format / what to enter
First six digits YYYYWW.

The model number is separate; do not enter an arbitrary short charger serial as the date code.

Scope matters

Supported formats
and historical limits.

  • The unique tool serial may contain only numbers or a mix of letters and numbers; it has no verified universal public date formula here.
  • Use the DATE CODE rather than substituting the unique serial, model or purchase date.
  • A date code gives year and week, not an exact calendar day, model, battery capacity or factory location.
  • Older short date-code formats remain unverified.

Research reviewed October 16, 2026. This independent tool applies published rules and retains unresolved years and model candidates.

Source references

Separate date code: YYYY-WW-XX

DEWALT eight-character date field, allowing the printed dashes/spaces.

The first four digits give manufacture year and the next two give week. The final two characters are retained in the entered code but have no verified factory or model meaning here. The source example is 2017-22-59. The source also suggests 2021-01-AA as a registration placeholder when the actual code is missing; that placeholder alone is not manufacture-date evidence.

Confirm that this is the separate YYYY-WW-XX DATE CODE, rather than the tool serial number.

Battery / charger: first six DATE CODE digits YYYYWW

First six digits of the date field on DEWALT batteries and chargers.

DEWALT asks for the first six date-code digits for batteries and chargers. These are the year and week positions of the documented DEWALT date format. Any following suffix is omitted from this short input.

Confirm these are the first six digits of the battery or charger DATE CODE, not an arbitrary six-digit serial.

Reading your result

DEWALT lookup questions

Why does the year code match more than one year?

Some systems reuse letters or only encode the last one or two year digits. Every supported interpretation is retained. A decade supplied from reliable records can narrow the reading; the tool does not automatically pick the newest year.

Does the serial identify my exact model?

Usually the model is a separate plate field. Where published serial ranges actually identify a model, the result shows model candidates and links to their manuals. Overlapping ranges remain ambiguous.

Can I share the result?

After a lookup, the address includes the serial in a fragment beginning with #serial=. Use “Copy share link” to share the serial and selected context. Opening the link runs the same lookup. The fragment is not a query-string result page.
