Replacement battery for JBL Charge 5

This KingSener GSP-1S3P-CH40 unit is a lithium-ion replacement battery built for the JBL Charge 5 portable wireless speaker. It delivers a rated capacity of 7500mAh and 27Wh at 3.6V. The pack uses brand-new cells and a matching PCB to restore original run time. Physical dimensions match the factory battery for direct installation.

Who this suits and who it does not

Owners of a JBL Charge 5 whose original pack no longer holds charge will find a direct-fit solution here. Buyers needing a battery for any other speaker model or device should look elsewhere because the connector and form factor are specific to this unit. The 100% new condition makes it unsuitable for anyone seeking a used or lower-cost alternative.

Deciding specification: 3.6V 7500mAh 27Wh Li-ion

The voltage of 3.6V combined with the 7500mAh / 27Wh capacity is the single figure that confirms compatibility with the Charge 5. If the original battery label shows different voltage or capacity values this pack will not work correctly. Verify the model number GSP-1S3P-CH40 on your old battery before ordering.

Questions about this item

Should I pick the 7500mAh or 27Wh version of the KingSener GSP-1S3P-CH40?

Both figures describe the same cell; 7500mAh at 3.6V equals 27Wh, so there is only one capacity to choose.

What runtime does the 27Wh rating give inside a JBL Charge 5 speaker?

The 27Wh pack matches the original design capacity, restoring the speaker's factory playtime per charge.

Does the 3.6V lithium-ion interface limit charging speed or compatibility?

The 3.6V Li-ion chemistry is identical to the original battery, so the speaker's built-in charger manages current and voltage without any cap change.
