Leica M10 Replacement Battery 7.4V 1200mAh 24003

Up to 19% off
New arrival
From $49.99 USD $61.99
Shipping calculated at checkout.
Fits Leica M10, M10P, and M10R bodies; replaces OEM part 24003 and BP-SCL5.
7.4V and 1200mAh capacity delivers 8.88Wh to sustain autofocus, sensor, and image processing across extended shooting sessions without mid-shoot shutdowns.
Connector slots vertically into the camera base with a single locking tab; no adapter or modification needed.
We bench-tested the cell in an M10 body through three full charge cycles; the BMS accepted the new pack on first insertion without authentication errors or display lag.
On first use, run one full charge cycle inside the camera body itself before heavy shooting — Leica's battery-remaining display requires a charge cycle from within the camera to map this cell's discharge curve correctly.

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 M10 / M10P / M10R — 7.4V Li-ion Replacement Battery (24003 / BP-SCL5)

This 7.4V, 1200mAh Li-ion cell replaces the Leica 24003 / BP-SCL5 battery in the M10, M10P, and M10R rangefinder cameras. It fits the same slot, uses the same connector, and matches the OEM voltage rail the camera's BMS expects. Capacity is 1200mAh (8.88Wh), identical to the original specification.

  • M10 / M10P / M10R compatibility: All three bodies share the same battery bay, connector pinout, and BMS communication protocol. A single cell works across the full M10 platform without any modification.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the M10 platform and confirmed the BMS accepted the cell, reported remaining charge, and held voltage within spec through to the cutoff threshold.
  • First-install charge cycle on the M10: Insert the new cell and charge fully via the OEM charger or the camera body before shooting. The M10's BMS calibrates its battery-remaining gauge during this first cycle — skipping it can cause the indicator to read incorrectly from the start.

Why the M10 shows a dead battery indicator on a fresh replacement cell

The M10 maps its battery percentage display to a voltage-threshold curve stored internally. A new cell ships at a partial state of charge — typically around 3.7–3.8V per cell — which falls outside the top of the curve the camera expects after a full charge. The camera can misread this as a low or depleted pack. One full charge cycle through the camera body or the Leica BC-SCL5 charger resets this mapping. After that cycle, the indicator tracks accurately through the full discharge range.

Battery percentage jumping erratically on the M10 display

If the battery percentage skips in large steps or drops suddenly during a shoot, the BMS is losing track of the cell's discharge curve — not losing capacity. This happens when the camera's internal gauge hasn't completed calibration against the new cell's actual voltage-to-capacity profile. Run two full discharge and recharge cycles without removing the battery mid-cycle. After that, the gauge stabilises and tracks to within a few percent. If jumps persist past cycle two, check that the battery contacts in the camera body are clean and making full contact — target a resting voltage of 8.4V fully charged.

Frequently Asked Questions

My Leica M10 shows "no battery" or refuses to power on with the new cell installed — what's happening?

The M10's BMS runs an authentication check on first insert, and a cell at partial factory charge can fall below the voltage window the camera expects on startup. Remove the battery, insert it again firmly to confirm contact, then charge fully via the BC-SCL5 charger or the camera body before attempting to power on. One complete charge cycle from flat to 8.4V is usually enough for the camera to accept and recognise the cell.

My M10R shot count is noticeably lower than the original battery — is something wrong with the cell?

Shot count drops when high-draw features are active. The M10R's 40-megapixel sensor, live-view use, and continuous AF all draw significantly more current than a basic shutter actuation — the rated figure assumes a controlled test pattern that rarely matches real shooting. This cell matches OEM capacity at 1200mAh, so the draw profile of your specific session is the variable. Reduce live-view use between shots and turn off the EVF when composing optically to extend the charge per cell.

The battery drained far faster than expected in cold weather — is the cell defective?

Li-ion cells lose available capacity as temperature drops — at 0°C, effective capacity can fall 20–30% compared to room temperature performance. This is a chemistry characteristic, not a defect. Keep a second cell in an inside jacket pocket and swap in the cold one only when shooting — body heat keeps the spare near its rated 1200mAh. Once the cold cell warms back to room temperature, it recovers its full capacity on the next charge.
