Samsung BP-70A Replacement Battery 3.7V 740mAh Li-ion

Shipping calculated at checkout.
Fits Samsung BP-70A, EA-BP70A, BP-70EP, SLB-70A original battery part numbers for SL50, SL600, ES65, ES70 digital cameras.
3.7V 740mAh lithium-ion cell delivers consistent voltage across the discharge curve for accurate exposure metering and flash recycling.
Connector is a two-pin contact block oriented vertically — seats into the camera battery bay with a spring-loaded latch that locks when fully inserted.
We bench-tested this cell in an SL50 body; the BMS accepted it on power-on without authentication delay and held voltage steady through a full charge cycle.
On first install, charge the camera body one full cycle via USB or OEM charger before heavy shooting — Samsung SL-series firmware maps battery percentage to the discharge curve during initial charge, and skipping this step causes erratic percentage 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.

Samsung SL50 / ES65 / ES70 Series — 3.7V Li-ion Replacement Battery (BP-70A)

This is a 3.7V, 740mAh Li-ion replacement cell for Samsung compact digital cameras using the BP-70A battery. It fits the SL50, SL600, ES65, ES70, and over 77 additional Samsung point-and-shoot bodies. Voltage and form factor match the OEM spec exactly — the cell slots into the battery compartment the same way the original does.

  • SL and ES series compatibility: These Samsung compact lines share the same BP-70A battery bay dimensions, 3.7V nominal voltage rail, and BMS communication protocol. Swapping between models in this family works because the connector orientation and cell geometry are identical across the platform.
  • Bench tested on actual hardware: We ran this cell in an SL50 body through a full charge-discharge cycle. The BMS accepted the cell on first install, reported charge status without error, and held voltage above 3.5V through the bulk of the discharge curve before the low-battery indicator triggered.
  • First charge cycle on the SL50: Charge this cell in the camera body via USB or OEM charger before your first shoot. Some Samsung compact BMS firmware maps the battery-remaining display against a baseline established during that initial in-body charge — skipping it can cause the indicator to read inaccurately for the first several sessions.

Why the SL50 battery percentage jumps erratically with a new cell

Samsung's compact camera BMS maps remaining charge against a voltage-threshold table calibrated to the original cell's discharge curve. A new third-party cell discharges along a slightly different curve, so the firmware reads voltage thresholds at the wrong points and jumps the percentage indicator. This typically resolves after two or three full charge-discharge cycles, once the BMS has logged enough data to track the new cell's actual behaviour. If jumping persists beyond three cycles, charge fully to 4.2V via the OEM charger and discharge through normal shooting — not storage mode.

Flash not fully recycling between shots on the SL50

The flash capacitor in the SL50 draws a sharp current spike to recharge between shots. When the cell is at low state of charge, internal resistance rises and the voltage sags under that spike — the capacitor doesn't reach full charge before the camera releases the shutter again. The result is visibly dimmer flash output on consecutive shots. This is a cell-state issue, not a camera fault. Charge the battery to full and the recycle behaviour returns to normal; if it doesn't, check the cell rests at or above 3.7V before shooting.

Frequently Asked Questions

My SL50 shows "no battery" or flashes a battery error even though the replacement cell is fully charged — what's happening?

Samsung compact camera firmware runs a brief authentication check when a new cell is installed. If the BMS doesn't recognise the cell on first contact, it throws a no-battery or incompatible warning even on a charged cell. Remove the battery, reinsert it firmly, then place the camera on charge via the OEM charger for a full cycle — most bodies clear the rejection flag after that first in-body charge completes. If the error persists, confirm the cell contacts are clean and the battery is seated flush against the connector pins.

I'm getting far fewer shots per charge than I expected — is the replacement cell undersized?

Shot count drops below spec when features like flash, continuous autofocus, and optical zoom motor draw run simultaneously — those loads add significantly to the per-shot current drain beyond what a basic shot-count estimate assumes. The cell capacity is 740mAh, matching the OEM spec. If depletion still seems unusually fast, check whether the LCD brightness is set to maximum and whether face-detection AF is active — both are constant draws. Dropping LCD brightness one level and shooting in single-shot AF mode recovers meaningful capacity per session.

The battery percentage on my ES70 reads 100% then drops to 20% after just a few shots — is the cell faulty?

This is a BMS calibration issue, not a faulty cell. The camera's voltage-threshold map was built around the original cell's discharge curve, and a new cell discharges differently — so the firmware misreads where it is on that curve and skips percentage steps. Run two full charge-discharge cycles through normal shooting without interrupting mid-cycle. By the third cycle the BMS has enough discharge history to track the new cell's curve accurately and the percentage readout stabilises.
