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 state-of-charge fuel gauge, just like the genuine DeWalt pack, so crews get quick visibility to remaining charge and can avoid jobsite interruptions.
My DCB205 battery won't charge / is not charging — why?
A genuine-spec replacement like ours should charge normally on DeWalt DCB115 / DCB1104 / DCB118 chargers. 'DCB205 battery not charging' is most often caused by a deeply discharged pack or a BMS-handshake mismatch on low-quality clones. 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 as single packs, DCB205-2 2-packs, and DCB205-2CK starter-kit configurations (battery + DCB115-class charger). Specify your preferred configuration and branding at order.
Which DeWalt tools and batteries is the DCB205 compatible with?
The DCB205 is a direct replacement across the DeWalt 20V MAX XR flat-pack system — compatible with DCB180 / DCB200 / DCB204 / DCB205 batteries and tools such as the DCD991B, DCD996B, and DCS380B.
What is the MOQ for the DCB205 replacement battery?
Standard MOQ is 100 units for the DCB205. Paid samples of 1–10 units are available for BMS-handshake validation before a production order. Private-label or custom-spec runs start at 500 units.
Is the DCB205 drop-in compatible with original DeWalt chargers?
Yes. The DCB205 BMS is flashed with model-specific firmware so it handshakes correctly with genuine DeWalt chargers (e.g. DCB115, DCB1104, DCB118) — charging, authentication, and safety lockouts behave identically to the OEM pack. Handshake is validated on 100% of units at end-of-line.
What cells and configuration does the DCB205 use?
The DCB205 uses Grade-A 18650 cells (5000mAh each) in a 5S2P configuration for a nominal 20V and a true rated capacity of 5.0Ah. Cells are matched by capacity (±20 mAh) and internal resistance (±5 mΩ) before assembly. Preferred cell brand (Samsung / LG / Panasonic / BAK) can be specified at order.
What is the warranty on the DCB205 replacement battery?
All DCB205 replacement packs carry a 12-month warranty against manufacturing defects. Every batch ships with UN38.3 test report, IEC 62133 certificate, MSDS and CE Declaration of Conformity for smooth customs clearance worldwide.
How is the DCB205 packed for shipping?
The DCB205 ships 20 pcs per master carton (13.0 kg gross), carton dimensions 443*290*170mm. Every batch ships with full UN38.3 / IEC 62133 / CE documentation for customs clearance.
