Core Technical Advantages
1. Compact 2.0Ah Form Factor
The DCB203 20V MAX XR compact 2.0Ah lithium-ion battery keeps weight and length to a minimum — ideal where the bulkier 5.0Ah DCB205 is overkill.
2. Full DCB201 / DCB203 Compatibility
Matched latch geometry and contacts mean the pack drops into the same tools as the DCB201 and DCB203 — a direct compact-class replacement.
3. Verified Charger Handshake
BMS handshakes correctly with DeWalt 20V MAX chargers (DCB115 / DCB1104); charging and protection behave identically to the genuine DCB203 — no 'battery not charging' faults from firmware mismatch.
