DEWALT DCB203 – Frequently Asked Questions

1) Will a DEWALT DCB203 2.0Ah battery run my older DEWALT 20V MAX tools?
The DCB203 works across the entire line of DEWALT 20V MAX tools, so any tool in that platform accepts it regardless of when you bought it. It is a 20V MAX lithium ion pack rated 2.0Ah and 40 watt hours. What it will not do is fit 18V stem-type DEWALT tools or 12V MAX tools, those use a different battery foot entirely.
2) Does the DCB203 come with a charger or a case?
Battery only. No charger is included and there is no case, so if this is your first 20V MAX pack you need to order a 20V MAX charger separately to do anything with it. If you already run DEWALT 20V MAX tools, your existing charger handles it. One battery per order.
3) Is the DCB203 a 20 volt or an 18 volt battery?
Both numbers describe the same pack. Maximum initial voltage measured without a workload is 20 volts, and nominal voltage is 18. So a DCB203 is the correct battery for a tool badged 20V MAX, and the 18V figure on a spec sheet is not a different product.
4) Should I buy the 2.0Ah compact pack or a larger amp hour DEWALT battery?
Pick the 2.0Ah DCB203 when weight and balance matter more than runtime: overhead drilling, working off a ladder, driving screws all day, a compact impact driver or drill you hold at arm's length. It carries 40 watt hours and weighs 0.91 lbs. Step up to a higher amp hour 20V MAX pack for current-hungry tools, circular saws, grinders, recip saws, or when you want fewer swaps across a shift. Either size runs on the same tools and the same chargers.
5) Can I ship or air freight DEWALT 20V MAX lithium batteries?
The DCB203 is a lithium ion cell pack and is handled as hazmat, carrying hazmat code C1. DEWALT publishes a UN38.3 lithium test summary for it, which is the document a carrier or a freight forwarder asks for when you move these in volume. Procurement teams stocking packs across multiple sites should keep that summary on file.
6) What is the DEWALT part number for the 20V MAX 2.0Ah compact battery?
DCB203 is the DEWALT model and manufacturer part number for the 20V MAX 2.0Ah compact lithium ion pack with the LED charge indicator. That is the number to quote on a purchase order or cross-reference against a submittal, and it identifies the 2.0Ah capacity specifically, not the higher amp hour packs in the same platform.
7) How long does a DEWALT DCB203 take to charge?
45 minutes. For a crew that means two packs and one charger keeps a tool running continuously, since the pack on the charger is ready before the one in the tool is flat on most jobs. The LED state-of-charge indicator on the battery lets you check where a pack is before you walk out to the truck.
8) How many DCB203 batteries do I need per tool?
One. DEWALT 20V MAX tools take a single battery, and the DCB203 ships as an individual pack rather than a two-pack. If you are standardizing a maintenance shop, plan on at least two per tool in active rotation so one is always on the 45-minute charge cycle.
9) Is the DCB203 battery housing tough enough for daily jobsite use?
The housing is molded plastic, the standard construction for DEWALT 20V MAX packs, and the pack is rechargeable for repeated cycles. At 0.91 lbs it is light enough that a dropped tool puts less mass behind the battery than a full-size pack does. Country of origin is China.
