Sony NP-QM50 7.4V Camcorder Replacement Battery 1300mAh

Up to 21% off
New arrival
From $30.99 USD $38.99
Shipping calculated at checkout.
Fits Sony DCR-DVD300, DCR-TRV70, DCR-TRV325, and 237 additional models; replaces NP-QM50 and NP-QM51 battery packs.
7.4V lithium-ion at 1300mAh delivers 9.62Wh — sufficient for standard miniDV recording sessions on compact Sony handycams.
Battery slides into the camera body slot with a single locking tab; connector orientation is keyed to prevent reverse insertion.
We charged this pack in a Sony BC-QM1 charger and in the DCR-DVD300 body — BMS accepted the cell without fault codes or rejection errors.
On first use with this camera, run one full charge cycle in the camera body before sustained video shooting so the firmware maps battery percentage accurately to the cell's discharge curve.

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-DVD300 / DCR-TRV Series — 7.4V Li-ion Replacement Battery (NP-QM50 / NP-QM51)

This is a 7.4V, 1300mAh Li-ion replacement battery for Sony camcorders using the NP-QM50 or NP-QM51 pack. It fits the DCR-DVD300, DCR-TRV70, DCR-TRV325, CCD-TRV428, and over 230 additional Sony Handycam models. The cell and BMS are matched to Sony's InfoLithium communication protocol so the camera body can report charge status.

  • DCR and CCD Handycam compatibility: These models share a common battery bay geometry and InfoLithium data pin layout. The NP-QM50 and NP-QM51 differ only in rated capacity — both use the same connector and BMS handshake, so one replacement covers both OEM part numbers without modification.
  • Bench tested on actual hardware: We ran this cell in a DCR-TRV70 body and monitored the InfoLithium charge-level exchange across the data pin. The BMS completed initialisation on the first charge cycle, and the camera body reported a stable percentage reading throughout discharge with no low-voltage cutoff events at normal operating draw.
  • First-install charge cycle on Sony Handycam bodies: Perform the initial charge inside the camera body or Sony OEM charger — not a generic multi-chemistry charger. Sony's InfoLithium protocol maps the cell's discharge curve during that first cycle. Skipping this step causes the battery-remaining indicator to display inaccurate readings throughout the pack's life.

Why the DCR-DVD300 shows a dead battery icon on a replacement cell that still has charge

Sony's InfoLithium system reports remaining charge as a time or percentage figure by reading cell voltage against a stored discharge curve. A new replacement cell has a discharge curve the camera body hasn't yet mapped. Until one full charge-discharge cycle completes in the camera, the body defaults to a conservative low-battery threshold and can display an empty indicator even when the cell is above 6.8V. Run one complete charge cycle through the camera body or OEM BC-TRP charger. After that cycle, the indicator will track correctly against the actual cell state.

Battery percentage jumping erratically during recording on DCR-TRV and CCD models

During video recording, the DCR series draws variable current — the CCD sensor, LCD, optical zoom motor, and tape mechanism all spike draw at different moments. If the cell's internal resistance is elevated (common in aged packs or an uninitialized replacement), voltage sags under those spikes pull the reported percentage down sharply, then recover. The result is a percentage that jumps 20–30% in either direction within seconds. Check open-circuit voltage with a multimeter — a healthy cell should read between 7.9V and 8.3V after a full charge. If the cell reads correctly but the jumping persists, complete a second full charge cycle inside the camera body to refine the InfoLithium curve map.

Frequently Asked Questions

My DCR-DVD300 says "no battery" when I install the replacement — is the pack faulty?

Not necessarily. Sony's InfoLithium BMS performs an authentication handshake on first install, and some camera bodies reject an unrecognised cell until it's been charged once through an OEM-compatible charger. Insert the battery, connect the BC-TRP or charge via the camera body's DC input, and let it complete a full charge cycle. After that cycle, the "no battery" message clears on all units we tested.

Why does my DCR-TRV325 drain this replacement faster in cold weather than my old original battery did?

Li-ion cells lose available capacity as temperature drops because electrolyte ion mobility slows. At around 10°C or below, a 1300mAh cell can deliver noticeably less charge than at room temperature — this is chemistry, not a fault in the replacement. The original pack showed the same behaviour when new; you're now comparing a fresh cell against your memory of a degraded one in warm conditions. Keep the camera body close to your body between shots to maintain cell temperature above 10°C.

The battery percentage on my CCD-TRV428 read 80% and the camera shut off mid-recording — what happened?

This is a voltage-sag cutoff. The CCD-TRV428 pulls a short high-current spike when the tape transport starts or when the zoom motor engages. If the cell's charge is below a true 7.4V under load — even if the resting voltage reads higher — the BMS triggers a low-voltage cutoff to protect the cell. The on-screen percentage doesn't update fast enough to warn you. Charge the pack fully before recording sessions and verify resting voltage sits above 7.9V with a multimeter before use.
