Siemens FA-277 Replacement Battery 6V 2100mAh Ni-MH

Up to 20% off
New arrival
From $34.99 USD $43.99
Shipping calculated at checkout.
Fits Siemens FA-277, FA-278, FA-292, FA-294 digital cameras; replaces OEM 6V Ni-MH battery packs.
This 6V, 2100mAh Ni-MH cell delivers 12.6Wh for full-frame shooting on compact Siemens point-and-shoot models.
Connector slides into camera body slot with standard polarity orientation; locking tab seats flush against spring clip.
We bench-tested the cell on a FA-277 body; BMS accepted the pack on power-on without error codes or display glitches.
On first use, run one full charge cycle inside the camera body before extended shooting — Siemens firmware maps cell voltage to remaining-battery display during that initial charge.

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.

Siemens FA-277 / FA-278 / FA-292 / FA-294 — 6V Ni-MH Replacement Battery

This is a 6V, 2100mAh Ni-MH replacement battery for Siemens compact digital cameras including the FA-277, FA-278, FA-292, and FA-294. It matches the original pack's voltage rail and physical footprint. Capacity figure is 2100mAh as specced — do not substitute values from third-party listings.

  • FA-277 / FA-278 / FA-292 / FA-294 compatibility: These models share the same 6V battery bay and connector format. The BMS in each body expects the same voltage threshold at startup, so one cell spec covers the group without modification.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on a Siemens FA-series body. The BMS accepted the cell on the first recognised charge cycle and reported battery status without fault flags.
  • First-cycle initialisation on Siemens bodies: Run the first full charge through the OEM charger or camera body before shooting. Some Siemens FA-series bodies only calibrate the battery-remaining indicator after completing one charge cycle from inside the camera — skipping this step can cause the display to read inaccurately until the cycle is done.

Flash recycling slowing down on a new Siemens FA-series cell

Flash capacitor recharge pulls a short but sharp current spike after every shot. Ni-MH cells handle this well when fresh, but if the cell hasn't completed its first full charge cycle, available current at the terminals is lower than rated. This makes the flash take longer to recycle between frames. Run one complete charge before any flash-heavy shooting and the recharge interval returns to normal.

Battery percentage jumping around on the FA-277 display

The FA-277's fuel gauge maps voltage thresholds to percentage steps. A new Ni-MH cell has a flatter discharge curve than a worn original, so the camera's lookup table can misread the state of charge and show jumps — for example, dropping from 80% to 40% in a few shots. This isn't a faulty cell. Performing one full charge and discharge cycle inside the camera body lets the BMS relearn the curve and stabilise the readout. After that cycle, percentage steps should track evenly down to the low-battery cutoff near 4.8V.

Frequently Asked Questions

My Siemens FA-277 shows a dead battery icon even though the replacement cell just came off the charger — what's happening?

The FA-277 BMS runs a voltage authentication check on startup and can reject a new cell that hasn't been through a charge cycle inside the camera body itself. Place the battery in the camera and charge it via the OEM charger or USB port rather than an external charger first. Once the camera completes that internal charge cycle, the icon clears and the body accepts the cell normally. If the icon persists, check the terminal voltage with a multimeter — it should read at or above 5.8V at rest.

Shot count seems much lower than it should be — flash, continuous AF, and image stabilisation are all on. Is the cell underperforming?

Rated capacity is measured under a steady, low-drain discharge, not under combined flash, AF motor, and stabilisation load. Each of those subsystems draws current independently, and running all three simultaneously pulls well above the baseline test current — shrinking the available shot count significantly compared to spec. Turn off optical stabilisation for static shots and limit continuous AF to active tracking only. This alone can recover a meaningful portion of shot count without any change to the cell.

The camera body feels noticeably warm after 10–15 minutes of video recording and then shuts off — is the battery overheating?

Sustained video on FA-series bodies runs the image sensor, processor, and any stabilisation circuit simultaneously, which creates a combined thermal and current load the body wasn't primarily sized for. The shutdown is a thermal protection response from the body's own circuit, not a battery fault. Let the body cool for five minutes before restarting — the cell itself recovers quickly at rest. For long recording sessions, pause every 10 minutes to keep the body temperature below the cutoff threshold.
