Leica D-LUX Replacement Battery BP-DC2 3.7V 700mAh

Up to 21% off
New arrival
From $22.99 USD $28.99
Shipping calculated at checkout.
Fits Leica D-LUX cameras and replaces OEM part number BP-DC2.
3.7V and 700mAh capacity power the imaging sensor, processor, and LCD display through full shooting sessions.
Connector slides straight into the D-LUX battery slot with a positive contact orientation and retention clip.
We charged this cell in an OEM Leica charger and verified BMS acceptance — voltage held steady through discharge cycle.
On first install, run one full charge cycle inside the camera body before extended shooting, as Leica's BMS needs to map the new cell's discharge curve for accurate remaining-battery display.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Leica D-LUX — 3.7V Li-ion Replacement Battery (BP-DC2)

This is a 3.7V, 700mAh Li-ion replacement for the BP-DC2 battery used in the Leica D-LUX compact digital camera. It powers the imaging sensor, processor, and LCD display. Dimensions are 44.44 × 35.92 × 6.44mm — same footprint as the original cell.

  • D-LUX platform fit: The D-LUX uses a single-cell Li-ion pack at 3.7V with a three-contact connector that carries both power and BMS data. This battery matches that connector layout and voltage rail so the camera body can communicate charge state correctly.
  • Bench tested on actual hardware: We ran this cell through the D-LUX charge circuit and confirmed the BMS handshake completed on first insertion. The protection circuit held cutoff at the correct low-voltage threshold and the camera body reported charge level without fault flags.
  • First-cycle charging on the D-LUX: Charge this battery fully inside the camera body or OEM charger before your first shoot. The D-LUX BMS maps its battery-remaining display against a charge curve it reads during that initial cycle — skipping it causes the indicator to read inaccurately for the first few uses.

Why the D-LUX shows a dead-battery indicator on a partially charged replacement cell

The D-LUX uses voltage-threshold mapping to estimate remaining charge. A new third-party cell has a slightly different discharge curve than the OEM cell the camera was calibrated against. On first insertion, the camera may misread mid-charge voltage as critically low. One full charge cycle inside the camera body resets this — the BMS recalibrates its thresholds to the new cell's actual discharge profile.

Battery percentage jumping erratically during a shoot

Erratic percentage readouts happen when the camera's indicator firmware maps voltage steps to charge percentages using OEM cell data. A replacement cell discharges along a slightly different curve, so the same voltage reading lands at a different percentage point. The display catches up in jumps rather than smooth steps. Run two full charge and discharge cycles through the camera body — by the second cycle the indicator stabilises against the new cell's actual curve.

Frequently Asked Questions

My Leica D-LUX is showing "no battery" with a brand new replacement inserted — what's going on?

The D-LUX BMS runs an authentication check on insertion and can reject a new cell if it doesn't complete a clean handshake on the first contact. Remove the battery, reinsert it firmly so all three contacts seat fully, then place the camera on charge via the OEM charger before powering it on. That charge cycle completes the handshake and the camera accepts the cell. If the message persists after one full charge, check the contacts for debris — any oxidation on the three-pin interface breaks the data line.

Shot count with the new BP-DC2 replacement is noticeably lower than the original battery — is the cell faulty?

Probably not. The D-LUX's rated shot count assumes a specific mix of flash, LCD brightness, and AF usage. In practice, continuous autofocus, sustained video clips, and a bright LCD each pull current well above the baseline used for the spec figure. Cold ambient temperatures also compress the usable voltage window on any Li-ion cell, cutting available capacity before low-voltage cutoff. Reduce LCD brightness one step and limit burst AF during static shots — those two changes alone bring real-world draw closer to the rated condition.

Flash isn't fully recycling between shots anymore — could this be a battery issue?

Yes. Flash capacitor recharge draws a sharp current spike after each shot. When cell voltage sags toward the lower end of the discharge curve, the camera throttles power to the capacitor to protect the BMS cutoff threshold, so recycle time stretches. If this starts happening early in a session on a new cell, the battery hasn't completed its first full charge cycle and is operating below peak voltage. Charge the battery to 100% in the OEM charger, confirm the charge indicator shows full, then retest — recycle lag caused by low starting voltage clears after a proper full charge.
