Replacement battery for JBL Clip 3 series
This lithium-polymer cell matches the original JBL L0721-LF part and fits the Clip 3, Clip 3AN and Clip 3SAND speakers. It delivers 1000mAh at 3.7 volts and measures 54.50 x 34.00 x 5.00 mm. The pack weighs 18.5 g and includes a fully decoded chip that communicates with the speaker exactly like the factory unit.
Sustained playback performance
After two or three full charge and discharge cycles the battery reaches its rated capacity and maintains a steady voltage through a typical listening session. The integrated protection circuit guards against overcharge, over-discharge, over-voltage and short-circuit events so the speaker can run continuously without sudden shutdowns. Capacity remains stable across repeated daily use.
Thermal behaviour and power draw
In normal indoor use the cell stays well below the 60 °C storage limit and generates no audible noise. Current draw follows the speaker’s own amplifier demand, so power consumption scales with volume level rather than the battery itself. The foam-padded packaging protects the pouch during transit, preventing puncture or deformation that could affect thermal performance.

Questions about this item
How much heat does the 3.7 V 1000 mAh lithium-polymer cell generate during continuous speaker playback?
The battery is designed to match original specifications and includes overcharge, over-discharge, over-voltage and short-circuit protection to keep operating temperature within safe limits during normal use.
What must I already own to install this replacement cell in my JBL Clip 3, Clip 3AN or Clip 3SAND?
You need the speaker itself and basic tools to open the enclosure and disconnect the original connector before fitting the new 54.50 × 34.00 × 5.00 mm pack.
Will the new fully decoded chip work with the original charging circuit in my older JBL Clip 3?
Yes, the decoded chip is engineered to function identically to the factory battery so the speaker’s existing charge management recognises and balances the cell correctly.
