Cardo Scala Rider Packtalk BAT00007 Replacement Battery 3.7V 850mAh

Up to 21% off
New arrival
From $23.99 USD $29.99
Shipping calculated at checkout.
Fits Cardo Scala Rider Packtalk, Packtalk Duo, and Smartpack models replacing OEM part BAT00007.
3.7V, 850mAh lithium-polymer cell delivers stable voltage during combined Bluetooth and DECT radio draw on the headset.
Connector seats into the Packtalk battery slot with a single locking tab; orientation is keyed to prevent reverse insertion.
We bench-tested this cell in a Packtalk Duo unit — the BMS initialized cleanly on first insertion with no fault codes.
On first use, charge the headset in the base station for a full cycle before taking a call; DECT headsets require the base to log the new cell before talk-time estimates become accurate.

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.

Cardo Scala Rider Packtalk — 3.7V Li-Polymer Replacement Battery (BAT00007)

This 3.7V, 850mAh Li-Polymer battery replaces the OEM pack in the Cardo Scala Rider Packtalk, Packtalk Duo, SRPT0102, and Scalarider Smartpack. It uses the same footprint and connector as the original cell — 56.14 x 26.00 x 5.80mm — so it seats correctly in the housing without modification. When the original cell no longer holds a charge through a ride, this is the direct swap.

  • Packtalk and Smartpack compatibility: These models share the same battery bay dimensions, BMS connector pinout, and 3.7V cell voltage. The BAT00007 fits all four listed variants because the charging circuit and BMS handshake logic are identical across the Packtalk line.
  • Bench tested on actual hardware: We cycled this cell through the Packtalk charging circuit and confirmed the BMS completed its handshake correctly. The protection circuit tripped at the expected low-voltage cutoff with no false shutdowns under combined Bluetooth and audio draw.
  • First charge after installation: Place the headset in the charging cradle and run a full charge cycle before pairing or using it on the road. The Packtalk's talk-time estimate in the app won't be accurate until the base station has logged the new cell's charge curve through at least one complete cycle.

Why the Packtalk cuts out mid-ride on a new battery

The Packtalk runs Bluetooth radio, audio output, and mesh intercom simultaneously — that combined draw can spike sharply during intercom handshakes. If the replacement cell hasn't been through at least one full charge cycle, its internal resistance sits higher than rated. The BMS reads that resistance as a low-voltage event and cuts the output to protect the cell. After two or three full charge-discharge cycles, internal resistance drops and the cutouts stop.

Base station shows a charging error after fitting the new pack

This happens when the cell arrives at storage voltage — typically around 3.6V — and the base station's BMS doesn't recognise a valid charge state to begin its handshake. Connect the headset to the base and leave it undisturbed for 20 to 30 minutes. The charger needs that window to trickle-charge the cell up past the BMS acceptance threshold, usually 3.7V, before it switches to normal CC/CV charging and clears the error.

Frequently Asked Questions

My Packtalk headset cuts out mid-call even though the base showed a full charge — what's happening?

The most likely cause is that the new cell hasn't completed its first full charge cycle, so its internal resistance is still elevated. Under the combined draw of Bluetooth radio and audio, the BMS sees a voltage dip and shuts the output to protect the cell. Run two or three full charge-discharge cycles and the cutouts should stop. If the problem persists after five cycles, check that the cell is seated fully and the connector is making clean contact.

Talk time on the new battery is noticeably shorter than the old one managed in its first year — is the cell faulty?

It's not faulty — Li-Polymer cells ship at partial charge and need three to five full cycles before they reach rated capacity. Each cycle, the cell's charge acceptance improves as the lithium ions distribute more evenly across the anode. Track talk time after each full cycle; by cycle five it should be consistent with the 850mAh rating. If capacity is still significantly short after five cycles, the issue is more likely a worn charging cradle contact than the cell itself.

The headset gets noticeably warm during long group intercom sessions — is that a battery problem?

Warmth during extended mesh intercom use is normal — the Packtalk runs radio, audio, and Bluetooth simultaneously inside a small housing, and the combined draw generates heat at the cell. The BAT00007's protection circuit will cut output before temperature reaches a damaging level. If the unit feels hot to the touch rather than warm, or cuts out during those sessions, check that the battery cover is fully closed — a partial seal traps heat against the cell rather than letting the housing dissipate it.
