Identification guide
Makita date code
A Makita date code is separate from DTD171 model wording and the long serial; a battery can use a different format from the tool’s year-month label.
Date label and serial
The Makita serial-location guide shows date wording alongside model and serial information. Read a clearly printed year-and-month field directly. The long serial and the model, such as DTD171, identify different information and should remain intact.
Explicit date example
| Printed field | Reading |

| Model code | Tool model |
| Serial number | Individual unit |
What to check next
Inspect the tool and battery labels separately. A battery code need not use the tool’s printed year-month arrangement. Record the exact model and every date character before comparing product-line instructions.
