Core Technical Advantages
1. True 5.0Ah 20V MAX XR Capacity
A 5S2P string of Grade-A 18650 cells delivers a genuine 5.0Ah — matching the DeWalt 20V MAX XR 5.0Ah lithium-ion battery DCB205 runtime spec, with no capacity inflation.
2. 3-LED State-of-Charge Indicator
Like the genuine pack, the DCB205 shows state of charge via a 3-LED fuel gauge so crews get quick visibility and avoid jobsite interruptions.
3. Verified Charger Handshake
BMS flashed with 20V MAX-specific firmware handshakes correctly with DeWalt DCB115 / DCB1104 / DCB118 chargers — charging, authentication, and safety lockouts behave identically to the OEM DCB205.

Frequently Asked by Distributors:
Does the DCB205 battery show state of charge?
Yes, the DCB205 has a 3-LED fuel gauge that shows how much battery power is left, just like the real DeWalt pack. This helps crews see how much battery power is left quickly, so they can avoid problems on the jobsite.
My DCB205 battery won't charge / is not charging — why?
A replacement that meets the original specifications should charge normally on DeWalt DCB115, DCB1104, and DCB118 chargers. The ‘DCB205 battery not charging’ issue is usually caused by the battery being completely drained or a problem with the BMS (battery management system) on low-quality copies of the battery. Our DCB205 BMS is validated against OEM chargers on 100% of units to avoid this.
Do you supply the DCB205-2 2-pack or DCB205-2CK starter kit?
Yes. We supply the DCB205 in single packs, 2-packs (DCB205-2), and starter kits (battery + DCB115-class charger). Choose your configuration and branding when you place your order.
Which DeWalt tools and batteries is the DCB205 compatible with?
The DCB205 is a direct replacement for the DeWalt 20V MAX XR flat-pack system. It works with the DCB180, DCB200, DCB204, and DCB205 batteries and tools, such as the DCD991B, DCD996B, and DCS380B.
