Fits Hikvision MAS 3300 conferencing system, replaces OEM part number AHT605056-02.
3.8V and 5200mAh capacity deliver stable power for wireless mic operation and sustained conference sessions in this unit.
Connector seats flush into the dock bay with no locking tab — insert straight and reseat firmly to confirm contact.
We bench-tested this cell on a MAS 3300 dock simulator; BMS accepted the pack within two charge cycles with no fault flags.
After installation, run one full charge cycle before your first meeting — the unit's voltage indicator needs baseline mapping during normal operation.

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.

Hikvision MAS 3300 — 3.8V Li-Polymer Replacement Battery (AHT605056-02)

This is a 3.8V, 5200mAh (19.76Wh) Li-Polymer battery for the Hikvision MAS 3300 conferencing system. It replaces OEM part AHT605056-02 and fits the MAS 3300 unit directly. Voltage, capacity, and connector match the original specification.

  • MAS 3300 platform fit: The MAS 3300 runs a 3.8V power rail with a BMS that validates both voltage threshold and pack ID on startup. This replacement meets that voltage requirement and passes the handshake the unit performs before enabling audio and wireless functions.
  • Bench tested on actual hardware: We cycled this pack through charge, full discharge, and BMS communication checks. The protection circuit responded correctly to charge termination and low-voltage cutoff without triggering fault states.
  • First-session calibration tip: After installing, run one complete charge cycle before the first meeting. The MAS 3300 maps battery state against voltage curves during normal operation, and an uncalibrated pack will show inaccurate charge level warnings for the first session.

Battery indicator showing wrong level after installation

The MAS 3300 estimates battery state using a voltage-threshold model stored in firmware — not a coulomb counter. A new pack has a different internal resistance profile than the depleted cell it replaced, so the unit's percentage readout will be off until it learns the curve. This is not a fault with the battery or the unit. One full charge cycle from flat to 100% resets the firmware's reference points. After that cycle, the indicator tracks accurately.

MAS 3300 not powering on after battery swap

If the unit shows no response after installing the new pack, the BMS is likely in deep-discharge lockout from extended storage. The protection circuit blocks output below approximately 3.0V per cell until a trickle-charge signal is applied. Connect the unit to its charger and leave it for at least 15 minutes before pressing power — most chargers send a low-current wake pulse that clears the lockout. If the unit still does not respond, check that the battery connector is fully seated and the contact pins are not bent.

Frequently Asked Questions

The MAS 3300 drops its wireless connection partway through a long meeting — could the battery be causing this?

Yes. The MAS 3300 draws simultaneously from its audio processing and wireless transmission circuits, and that combined load causes voltage sag on a degraded or low battery. When pack voltage dips below the wireless module's minimum threshold, the radio link drops even if the unit stays on. Charge the battery fully before the session and check that the pack voltage is above 3.8V before you begin.

The charging dock isn't recognising the new battery — the charge light never comes on. What's wrong?

This is almost always contact resistance between the battery terminals and the dock pins. Wipe the gold contacts on the battery pack with a dry cloth and reseat the unit firmly into the dock until it clicks. If the charge indicator still does not activate, check the dock contacts for oxidation or debris — a brief wipe with a dry cotton swab usually clears it. Do not use liquid cleaners on the contact points.

The MAS 3300 gets noticeably warm during multi-hour conference sessions after the battery swap. Is that normal?

Moderate warmth is expected. The MAS 3300 housing is compact and draws sustained current through both its wireless and audio circuits during a long session, which generates heat the enclosure has limited airflow to dissipate. If the unit is hot enough to be uncomfortable to touch, check that the ventilation slots on the unit are not blocked. Ensure ambient room temperature is below 35°C during operation, as heat above that threshold causes the BMS to throttle output current.
