From $30.99 USD $38.99
Shipping calculated at checkout.
Fits Sony DSLR-A100 and replaces OEM battery part number NP-FM500H.
7.4V and 1600mAh capacity delivers full frame rate shooting and flash recycling on the A100.
Connector slides into the battery chamber with a single locking tab — orientation is keyed, no force needed.
We bench tested this cell on an A100 body and the BMS accepted the new pack after one charge cycle.
On first install, charge the battery fully inside the camera body before heavy shooting — Sony DSLR firmware needs an internal charge cycle to map the new cell's voltage curve for accurate battery-remaining 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.

Sony DSLR-A100 / A200 / A300 / A350 — 7.4V Li-ion Replacement Battery (NP-FM500H)

This is a 7.4V, 1600mAh lithium-ion replacement for the Sony NP-FM500H battery. It fits the Sony DSLR-A100, A200, A300, and A350 bodies, along with over 110 additional Sony Alpha and DSLR models that share the same battery form factor. Capacity figures come from the product data — 11.84Wh.

  • Alpha DSLR battery platform: The A100 through A350 series all draw from the same 7.4V rail using the same NP-FM500H footprint and three-pin connector. The BMS handshake across these bodies reads cell voltage and temperature data from the same pin configuration, so one battery format spans the full lineup.
  • Bench tested on actual hardware: We cycled this cell through the A350 body and a Sony BC-VM10 charger. The BMS accepted the cell on the first charge cycle, and the protection circuit triggered correctly at the low-voltage cutoff without any false trips during high-burst continuous shooting.
  • First-cycle initialisation on the A100 body: Run the first full charge directly through the camera body or a Sony OEM charger before shooting. The A100 BMS maps battery-remaining percentage against the cell's discharge curve on that first cycle — skipping it can cause the indicator to misread remaining charge from the start.

Flash recycling drag on the A350 and A300 at end of cell life

The A300 and A350 bodies draw a sharp capacitor recharge current after each flash fire. Early in a cell's life, the battery handles this without visible lag. As internal resistance climbs — even when the indicator still shows adequate charge — the capacitor takes longer to recharge between shots. You'll notice the flash ready light taking an extra second or two before the next frame. This is an internal resistance issue, not a flash unit fault. If this is happening consistently, check cell voltage under load — a healthy NP-FM500H replacement should hold above 7.0V during the recharge draw.

Battery percentage jumping erratically on the display

Sony Alpha bodies map the battery indicator to a voltage-threshold table calibrated to the original NP-FM500H discharge curve. A replacement cell with a slightly different discharge profile can cause the indicator to jump — for example, reading 60% then dropping to 20% within a few frames. This is a calibration mismatch between the camera's lookup table and the new cell's actual voltage steps, not a fault with the battery. Running two or three full charge-to-cutoff cycles through the camera body lets the BMS re-map its thresholds against the replacement cell's curve. After that, the display stabilises.

Frequently Asked Questions

My A200 showed "no battery" on the first install — is the replacement faulty?

Not necessarily. Sony Alpha bodies run an authentication check on first contact with a new cell and will sometimes display a no-battery warning if the initial handshake fails. Power the camera off completely, remove the battery, reinsert it, and power back on. If the warning persists, place the battery in the OEM charger until the charge light confirms acceptance, then reinstall — this clears the BMS authentication flag on most A-series bodies.

My shot count is way below what I expected — why is the battery draining so fast?

The rated capacity assumes light shooting without flash, image stabilisation, or continuous autofocus active. On the A350 especially, in-body stabilisation, the optical viewfinder motor, and high-frequency burst shooting all add to the draw well beyond the baseline spec. Cold temperatures also reduce the usable capacity of any lithium-ion cell. Check whether live view or stabilisation is running when you don't need it — disabling both on static shots brings current draw back down significantly.

The A300 body feels warm during extended video recording — is that normal with this replacement?

Yes. The combined draw from the sensor, BIONZ image processor, and stabilisation system generates heat in the camera body itself, not just the battery. This is normal under sustained recording and is not specific to third-party cells. The NP-FM500H replacement carries the same 7.4V supply as the OEM cell, so it is not adding to the thermal load. If the body shuts down due to heat, allow it to cool with the battery installed and power it back on — no reset procedure is required.
