Canon EOS D2000 Replacement Battery DR-17 7.2V 2150mAh

Canon EOS D2000 / EOS D6000 — 7.2V Ni-MH Replacement Battery (DR-17)

This is a 7.2V, 2150mAh Ni-MH replacement battery for the Canon EOS D2000 and EOS D6000 digital cameras. It replaces OEM part numbers DR-17, DR-17AA, and DR17. The cell powers the imaging sensor, autofocus motor, and LCD display through a standard shooting session.

• EOS D2000 and D6000 compatibility: Both cameras share the same battery bay geometry, contact layout, and 7.2V supply rail, which is why a single cell covers both models. The BMS in each body reads the same voltage thresholds and charge termination signals from this chemistry.
• Bench tested on actual hardware: We cycled this cell through the OEM charger and monitored charge termination. The BMS accepted the cell cleanly after one full charge cycle, and the battery-remaining indicator stabilised on the second cycle.
• First-install charge cycle on Ni-MH camera cells: Ni-MH cells shipped at partial charge can confuse the EOS D2000's fuel gauge on first use. Run one complete charge-to-full cycle in the OEM charger or camera body before your first shoot — this lets the BMS map the actual capacity curve and display an accurate shot count.

Why the EOS D2000 shows a dead battery indicator on a partially charged replacement cell

The EOS D2000 maps its battery indicator to specific voltage thresholds calibrated for the discharge curve of a conditioned Ni-MH cell. A new, unconditioned replacement arrives at a resting voltage that sits in an ambiguous range — the camera reads it as depleted rather than partially charged. This is not a fault with the cell. One full charge cycle from the OEM charger brings the cell's resting voltage into the range the BMS expects, and the indicator will read correctly from that point forward.

Battery percentage jumping erratically mid-shoot on the EOS D6000

Ni-MH cells have a flatter discharge curve than Li-ion, and the EOS D6000's indicator is calibrated to read voltage steps that assume a conditioned cell. On a new or recently stored cell, the open-circuit voltage doesn't drop smoothly under autofocus and flash load — it sags and recovers in bursts, which causes the percentage display to jump. The fix is two full charge-discharge cycles to condition the cell's internal resistance. After conditioning, the resting voltage between shots stabilises and the indicator tracks normally.
