Drop-in replacement for JBL Charge 3

The KingSener GSP1029102A is a 6000 mAh 3.7 V lithium-ion battery built to match the original pack in the JBL Charge 3 Bluetooth speaker. It restores full portable run-time for owners whose factory cell no longer holds a charge.

Fits the existing battery cavity without

Same physical footprint and connector layout mean the pack slides straight into the speaker chassis — no soldering, no adapters and no case trimming required. The swap frees the speaker from permanent mains tethering and returns it to genuine wireless use.

Li-ion chemistry runs cool at nominal 3.7 V

Normal playback draws modest current so the cell stays near ambient temperature and produces no audible noise. Capacity remains above 80 % after a full charge cycle and the pack holds that level when stored above 80 % charge for up to a month.

Questions about this item

How long will the 6000 mAh capacity last during continuous playback at high volume?

The 6000 mAh lithium-ion cell matches the original design capacity so run-time equals the factory specification for the JBL Charge 3.

Does the 3.7 V cell run hot or make any noise when the speaker is used all day?

The replacement battery produces no audible noise and normal operating temperature stays within the speaker’s original thermal limits.

What tools or parts are needed to install the GSP1029102A battery in the speaker?

The pack is the same size as the original and uses the stock connector, so only a small screwdriver is required for the swap.
