Up to 21% off
New arrival
Sale priceFrom $23.99 USD Regular price $29.99
Shipping calculated at checkout.
Fits Leica X1 compact camera; replaces OEM battery BP-DC8, part 18706, EA-DC-8.
3.7V, 1400mAh cell delivers 5.18Wh — standard capacity for X1 shooting sessions without flash drain.
Connector slides straight into X1 battery slot; locking tab seats flush with camera body frame.
We charged this cell in an X1 body; BMS accepted the pack on first insertion with no authentication delay.
On first use, run one full charge cycle in the X1 body before heavy shooting — Leica's firmware maps battery percentage to this cell's discharge curve during that initial cycle.

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 X1 — 3.7V Li-ion Replacement Battery (BP-DC8)

This is a 3.7V, 1400mAh Li-ion cell built to the BP-DC8 specification for the Leica X1 compact digital camera. It fits the X1 body directly, using the same connector and contact layout as the original. Voltage and capacity match OEM figures — 3.7V nominal, 5.18Wh total energy.

  • Leica X1 fit: The X1 uses a single BP-DC8 cell to power both the sensor and the fixed 36mm Elmarit lens drive. There is no multi-cell pack here — one cell does all the work, so exact voltage tolerance matters to the body's power management logic.
  • Bench tested on actual hardware: We cycled this cell through the X1 body and a compatible BP-DC8 charger. The BMS accepted the cell on first insert, reported charge state correctly, and held cutoff at the expected low-voltage threshold without tripping early.
  • Charger compatibility on first use: The X1 body can charge via USB in some configurations, but the BMS reads the cell most accurately when the first full charge runs through a dedicated BP-DC8 charger. Skipping this can cause the battery indicator to display incorrectly for the first few cycles.

Why the X1 battery indicator reads full then drops suddenly

The X1 maps battery percentage to fixed voltage thresholds set for the original Panasonic-sourced BP-DC8 cell. A new third-party cell may have a slightly different discharge curve, sitting above the first threshold longer before dropping. This makes the indicator hold at full or high for an extended period, then fall faster near the end. It is not a fault — it normalises after two or three full charge and discharge cycles as the BMS learns the cell's actual curve.

X1 displaying "no battery" or rejecting a valid cell on insert

The X1 performs a contact handshake on power-up. If the cell voltage is below roughly 3.0V on arrival — which can happen after long storage in transit — the body may refuse to initialise and show no battery detected. Place the cell in a dedicated BP-DC8 charger first and bring it to at least 3.6V before inserting it into the camera. Once the charger confirms a partial charge, the body will accept it and resume normal communication.

Frequently Asked Questions

My Leica X1 battery percentage jumps from 60% straight down to 10% with no warning — is the cell faulty?

This is a voltage-threshold mapping issue, not a defective cell. The X1 indicator is calibrated to specific voltage steps from the original BP-DC8 discharge curve, and a new cell's curve may not align exactly with those steps at first. The result is a sudden drop when the cell crosses a threshold the camera wasn't expecting at that point. Run two or three full charge and discharge cycles through the body and the jumps will reduce as the reading stabilises.

The X1 shot count seems lower than I expected — flash fires about 80 shots and the battery warns low already.

Flash recharge is the single largest draw on the X1's BP-DC8 cell — each pop pulls a surge current to refill the capacitor, well beyond what continuous shooting without flash demands. That recharge current sag shortens the effective shot count significantly compared to shooting in natural light. If you're shooting events with flash at every frame, expect roughly half the shot count you'd get in daylight-only conditions. Reducing flash frequency or switching to auto flash only when needed is the most direct way to extend the charge.

After leaving my X1 unused for two months, the battery won't charge past the first bar — did it fail in storage?

Li-ion cells self-discharge in storage, and two months is enough for a BP-DC8 cell to drop below 3.0V if it wasn't stored at a partial charge. At that voltage the X1 body may not recognise the cell, and some chargers will also refuse to begin a charge cycle. Place the cell in a charger that supports a recovery or wake-up mode — these apply a low trickle current to bring the cell back above 3.0V before switching to standard CC/CV charging. Once it reaches 3.6V the charger should resume normally.
