Battery Care Tips
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
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 Pulse 4 — 3.7V Li-ion Replacement Battery (SUN-INTE-168)
This is a 3.7V, 7800mAh (28.86Wh) Li-ion replacement battery for the JBL Pulse 4 portable Bluetooth speaker. It restores power to the speaker's audio amplifier, Bluetooth radio, and LED light ring. Fit is confirmed against OEM part numbers SUN-INTE-168 and DH03073CHM.
- Pulse 4 compatibility: The Pulse 4 runs a single-cell 3.7V pack that powers both the Class D amplifier and the LED sync circuit from the same voltage rail. This cell matches that rail and the connector pinout used by the Pulse 4's charge management IC.
- Bench tested on actual hardware: We cycled this pack through the Pulse 4's onboard BMS and confirmed the protection circuit trips correctly on overcurrent and that the fuel gauge registers capacity accurately across charge states.
- Discharge cycling for the Pulse 4: The Pulse 4 is typically kept on a desk and topped off constantly. Let the battery drop below 20% at least once a month before recharging — skipping this causes fuel gauge drift and accelerates cell capacity fade.
Why the Pulse 4 LED ring flickers under heavy bass at high volume
The LED ring and amplifier share the same battery rail. At high volume with heavy bass, the amplifier pulls sharp current spikes. If the cell's internal resistance is elevated — common in aged packs — voltage on the shared rail briefly sags. The LED controller reads that sag as a low-power event and dims or flickers the ring. A fresh cell with lower internal resistance holds the rail steady under those spikes.
Pulse 4 not waking from USB-C charge after sitting unused for months
Li-ion cells left fully discharged for extended periods drop below the minimum voltage USB-C PD chargers will accept — typically around 2.5V per cell. The Pulse 4's BMS blocks charge input at that level to protect the cell, so the speaker appears completely dead. Some packs recover with a trickle charge applied directly, but if the cell has sat below 2.5V for weeks, recovery is unlikely. Prevent this by storing the speaker at 40–60% charge if it won't be used for more than a few weeks.

Frequently Asked Questions
My Pulse 4 shows full charge on the indicator but the audio cuts out after about an hour of use — is that a battery problem?
Yes — this is fuel gauge drift, not a faulty indicator circuit. It happens when the battery is shallow-cycled repeatedly without ever running down, causing the onboard fuel gauge to lose track of the real state of charge. The speaker's protection circuit then cuts audio when the true cell voltage drops to the safety floor, even though the display still reads full. Let the battery discharge below 20% on the next session before recharging to recalibrate the gauge.
The Pulse 4 audio distorts and breaks up before the battery indicator reaches empty — what causes that?
That's amplifier clipping under voltage sag. As the cell discharges toward its lower voltage limit, internal resistance rises and the rail voltage drops under the amplifier's current demand. The amplifier can't maintain clean output at that reduced rail voltage and clips the signal before the battery indicator formally hits empty. The indicator threshold and the amplifier's minimum operating voltage are not the same point — the amp hits its floor first. If this happens consistently before the 20% mark, the cell has degraded; replace it.
The Pulse 4 gets noticeably warm near the base during long play sessions — is that normal or a sign the new battery is failing?
Some warmth is expected. The Pulse 4's Class D amplifier and the Li-ion cell both generate heat during sustained playback, and the speaker's fabric and plastic housing traps it. What's not normal is heat that's uncomfortable to hold or that triggers an automatic shutdown. If the speaker shuts off mid-session and restarts after cooling down, the BMS is triggering a thermal cutoff. Check that the bass port and vents are unobstructed, and avoid placing the speaker on soft surfaces like cushions that block airflow to the base.
