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.

Proscan CC566 / CC577 / CCHIT566 Series — 7.4V Li-ion Replacement Battery

This 7.4V 3400mAh (25.16Wh) lithium-ion battery fits the Proscan CC566, CC577, CCHIT555, CCHIT566, and nine additional Proscan camcorder models. It slots into the same battery compartment as the original cell and connects via the same multi-pin interface. Capacity comes from the product data — 3400mAh at 7.4V nominal.

  • CC566 / CC577 / CCHIT series compatibility: These Proscan camcorder models share the same battery footprint, voltage rail, and connector pinout. The BMS in each body reads the same charge state lines, so one cell covers the full group without adapter or modification.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on a compatible Proscan body. The BMS accepted the cell without fault codes, held a stable voltage curve across the discharge, and cut off cleanly at the low-voltage threshold.
  • First-install charge cycle on Proscan bodies: On first use, run a complete charge cycle through the camcorder body or OEM charger before shooting. Some Proscan BMS firmware maps the battery-remaining display to the discharge curve during that first cycle — skipping it can cause the indicator to read inaccurately for several sessions.

Why the CC566 shows a dead battery icon on a freshly charged replacement cell

The CC566 battery indicator maps percentage to voltage thresholds calibrated against the original cell's discharge curve. A new third-party cell can have a slightly different curve shape, which the firmware reads as empty even when the cell is at 80–90% charge. This is not a fault in the battery — it is a threshold mismatch in the indicator logic. One or two full charge cycles through the camera body usually re-anchors the display to the new cell's actual curve.

Battery percentage jumping erratically on the Proscan display mid-recording

Erratic percentage readouts during recording are caused by the voltage-threshold indicator sampling at moments of high sensor and processor draw, which temporarily sags cell voltage below a display threshold. The camera firmware interprets the sag as a step-down in charge state and updates the indicator instantly. The actual cell capacity is not dropping — the display is reacting to load-induced voltage dips. Charge the cell fully to 8.4V and run one uninterrupted recording session to let the BMS re-establish its state-of-charge reference.

Frequently Asked Questions

My Proscan CC566 says "no battery" when I insert the new cell — is the battery dead out of the box?

Almost certainly not. The CC566 BMS runs an authentication check on first insertion and can reject a new cell if it hasn't been introduced via a charge cycle. Insert the battery and connect the camcorder to its OEM charger for a full charge before powering it on for the first time. That charge cycle initialises the BMS handshake. If the body still shows no battery after a full charge, check that the battery contacts are fully seated — the CC566 compartment latch needs to click closed before the pins make contact.

The shot count on my CC566 is way lower than I expected from a 3400mAh cell — what's happening?

Shot count specs are measured under controlled conditions with minimal ancillary load. On the CC566, continuous autofocus, optical zoom motor activity, the LCD screen, and the recording codec all draw current simultaneously during video capture — that combined draw is significantly higher than a simple still-shot count implies. The 3400mAh capacity is accurate, but real-world recording load pulls more current per minute than the baseline spec assumes. To extend recording time per charge, dim the LCD to its lowest usable setting and avoid continuous optical zoom during recording.

The replacement battery worked fine for a week, then the CC566 started feeling warm during recording and cutting out early — what causes that?

Heat during sustained video recording is normal on the CC566 — the sensor, image processor, and writing buffer all generate heat that transfers into the battery compartment. When compartment temperature rises, the BMS lowers its discharge ceiling to protect the cell, which shortens available capacity before the low-voltage cutoff triggers. This is the BMS working correctly, not a faulty cell. Let the camcorder cool for 10–15 minutes between extended recording sessions, and avoid leaving it in direct sunlight between takes — compartment temperature above 45°C will trigger early cutoff regardless of remaining charge.
