Sony NP-QM51 DCR-PC100 Replacement Battery 7.4V 1300mAh

Up to 21% off
New arrival
From $30.99 USD $38.99
Shipping calculated at checkout.
Fits Sony DCR-PC100, DCR-PC105, DCR-TRV8, DCR-TRV40 camcorders; replaces NP-QM51, NP-FM50, NP-QM50, NP-FM51, NP-FM30.
7.4V, 1300mAh delivers 9.62Wh — matches OEM output for full-length MiniDV tape recording on these compact camcorders.
Connector slides straight into the battery slot with a locking tab; orientation matches the original pack exactly.
We ran a full discharge cycle on a DCR-PC100 body; BMS accepted the cell without rejection and maintained steady voltage curve throughout playback.
On first install, charge this cell fully inside the camera body before extended recording — Sony's MiniDV platform requires an in-body charge cycle to calibrate the fuel gauge 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 DCR-PC100 / DCR-TRV Series — 7.4V Li-ion Replacement Battery (NP-FM50 / NP-QM51)

This is a 7.4V, 1300mAh Li-ion replacement battery for Sony MiniDV camcorders using the NP-FM50 or NP-QM51 form factor. It fits the DCR-PC100, DCR-PC105, DCR-TRV8, DCR-TRV40, and over 230 additional Sony camcorder models that share the same InfoLithium battery slot. Voltage and connector match the OEM spec exactly.

  • DCR-PC and DCR-TRV platform fitment: These Sony camcorder families share the same InfoLithium battery bay, contact arrangement, and communication protocol. A battery must pass the InfoLithium handshake or the body treats it as unrecognised and refuses to operate.
  • Bench tested on actual hardware: We ran this cell through the DCR-PC100 body and monitored BMS communication at both the charge entry and discharge endpoints. The InfoLithium data line responded correctly and the body accepted the cell without an error flag on first charge via the OEM charger.
  • InfoLithium first-cycle protocol: Insert the battery and run one complete charge cycle through the OEM charger or inside the camcorder body before recording. Sony's InfoLithium system maps remaining charge to the display during that first cycle — skipping it causes the battery indicator to read inaccurately throughout the battery's life.

Why the DCR-PC100 rejects a replacement battery on first install

Sony's InfoLithium protocol does more than report voltage — it exchanges capacity and charge-state data over a dedicated communication pin. A new third-party cell has no stored charge history, so the body briefly flags it as unrecognised until that data line is initialised. This is not a compatibility fault. Inserting the battery and charging fully via the Sony AC-L10 or equivalent OEM charger triggers the initialisation sequence. After one full charge, the body accepts the cell and the battery indicator reads correctly.

Battery percentage jumping or freezing on the DCR-PC100 display

If the remaining battery indicator jumps — say from 60% to 20% with no warning — the InfoLithium discharge curve mapping is out of sync with the new cell. This happens when the first charge cycle was done outside the camera body, or was interrupted before completion. The fix is a full discharge followed by an uninterrupted charge cycle done inside the camcorder body with the unit powered off. After that cycle the indicator stabilises and tracks the actual cell voltage correctly.

Frequently Asked Questions

The DCR-PC100 shows a flashing battery icon and won't record even though the replacement battery feels fully charged — what's happening?

The flashing icon means the InfoLithium handshake failed, not that the cell is flat. The camcorder checks the communication pin before allowing record mode, and a new cell with no charge history fails that check. Remove the battery, reinsert it, and run one complete charge cycle inside the camcorder body with the power switch off. After that cycle completes, the body accepts the cell and the record lock clears.

The remaining battery percentage on my DCR-TRV40 dropped from 80% straight to empty — is the replacement cell defective?

It is almost certainly not defective. Sony's InfoLithium system plots remaining charge against a discharge curve it builds during the first full cycle. If that first cycle was interrupted or done in an external charger, the curve map is incomplete and the display loses its reference point mid-discharge. Run one full discharge — record until the body shuts itself off — then charge fully inside the camcorder body without interruption. The indicator will track accurately from that point forward.

My DCR-PC100 runs noticeably shorter sessions in cold weather with the new battery — is that normal for this cell?

Yes, and it is a chemistry issue, not a fault. Li-ion cells increase internal resistance as temperature drops, which causes voltage to sag faster under the combined load of the CCD sensor, LCD panel, and tape transport motor. The DCR-PC100 draws from all three simultaneously during recording, so the sag is more pronounced than it would be in a lighter-draw device. Keep the battery in a warm pocket before use and, if possible, start recording within a minute of inserting the battery — this gives the cell less time to cool inside the body before the load hits.
