JBL PartyBox 110 Replacement Battery 7.4V 6800mAh IBA064GA

Up to 19% off
New arrival
From $80.99 USD $99.99
Shipping calculated at checkout.
Fits JBL PartyBox 110 speaker; replaces OEM part IBA064GA.
7.4V, 6800mAh lithium-ion cell delivers full charge to the amplifier and Bluetooth radio without voltage sag during peak playback.
Connector slides into the rear battery cavity with a single locking tab; orientation keyed to prevent misalignment.
We ran the cell through a full discharge cycle on the PartyBox 110 at volume level 8 — BMS stayed stable, no early cutoff.
On first charge, the PartyBox 110 fuel gauge may show inaccuracy for two discharge cycles; run the speaker below 20% capacity once before relying on the indicator.

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.

JBL PartyBox 110 — 7.4V Li-ion Replacement Battery (IBA064GA / ICA002GA)

This 7.4V, 6800mAh Li-ion battery replaces the original pack in the JBL PartyBox 110 portable Bluetooth speaker. It slots into the same battery bay and connects to the same BMS interface as the factory unit. If your PartyBox 110 no longer holds charge or cuts out mid-session, this is the direct cell replacement.

  • PartyBox 110 compatibility: The PartyBox 110 uses a 7.4V two-cell Li-ion configuration to supply both the Class D amplifier rail and the Bluetooth radio simultaneously. This pack matches that voltage rail and the connector pinout, so the onboard BMS handshakes correctly without a charge error flag.
  • Bench tested on actual hardware: We cycled this pack through full charge and discharge on the PartyBox 110 platform. The BMS accepted charge from the AC adapter without tripping a protection fault, and the amplifier rail held voltage under high-volume output.
  • Monthly discharge cycle for the PartyBox 110: If the speaker sits plugged in between uses, let it discharge below 20% at least once a month before recharging. Constant top-off charging without a full discharge causes fuel gauge drift specific to this platform, where the indicator reads full but the usable capacity has silently shrunk.

Why the PartyBox 110 runs warm inside the fabric housing during extended play

The PartyBox 110 encloses the amplifier board and battery pack inside a fabric-wrapped cabinet with limited airflow. At high volume, the Class D amplifier generates heat at the same time the Li-ion cells are discharging under load. Both heat sources share the same enclosed space. An old or degraded battery compounds this — higher internal resistance under discharge means more heat generated per amp drawn. A fresh pack with lower internal resistance runs noticeably cooler in the same housing.

Audio distorting before the battery indicator reaches empty

This happens when the battery's internal resistance has risen enough that voltage sags under amplifier draw before the cell is actually depleted. The BMS still reads the pack as partially charged, but the voltage delivered to the amplifier rail drops below the threshold needed for clean output. The amplifier clips the signal rather than cutting off cleanly, which is why you hear distortion instead of a low-battery warning. If this is occurring regularly, check resting cell voltage — a healthy 7.4V two-cell pack should read 8.3–8.4V off the charger.

Frequently Asked Questions

My PartyBox 110 Bluetooth keeps dropping out when I push the volume past 75% — is that the battery?

Yes, this is a known voltage-sag issue on the PartyBox 110. At high volume, the Class D amplifier draws a heavy current spike that, combined with the Bluetooth radio draw, pulls the pack voltage down momentarily. A degraded battery with elevated internal resistance can't sustain that combined load, so the radio loses power briefly and disconnects. Replace the pack and confirm resting voltage reads 8.3V or above off the charger before testing.

The PartyBox 110 shows a full charge on the indicator but audio cuts out after about an hour of use — what's going on?

This is fuel gauge drift caused by shallow cycling — the battery was repeatedly topped off without being allowed to discharge fully, so the onboard BMS lost its accurate state-of-charge reference. The indicator reads full, but the actual usable capacity has degraded. A replacement pack resets that baseline, but you'll need to run one full discharge below 20% before recharging to let the BMS calibrate correctly.

My PartyBox 110 won't respond at all when I plug in the AC adapter after it sat unused for several months — the charge LED doesn't even blink.

A long storage period can push the Li-ion cells below the minimum voltage the BMS will accept for charging — typically under 2.5V per cell. At that point the protection circuit blocks charge input entirely to prevent thermal runaway, which is why there's no LED response. The original pack is likely unrecoverable at that voltage level. Fit the replacement pack, connect the AC adapter, and the BMS should acknowledge charge within 60 seconds — confirmed by the charge LED activating.
