Compatible JBL Headsets

This Cameron & Co DS-CS-JBE400SL battery replaces the original P062831 cell in JBL Synchros S400BT, Tune 500BT and Tune 600BT wireless headsets. It is a 3.7 V lithium-polymer unit rated at .6 Ah and 2.22 Wh. The pack is supplied new and 100 % OEM compatible for direct installation.

Thermals and Power Draw

Lithium-polymer chemistry keeps self-discharge low and delivers steady voltage during typical listening sessions. Normal use produces no audible noise and negligible heat inside the earcup. The 2.22 Wh capacity restores the original runtime without increasing power demand on the headset electronics.

Build and Connectors

The black cell measures 30.76 x 30.00 x 6.64 mm, matching the factory footprint for a secure fit in the battery compartment. Original wiring and connector layout are retained so no soldering or adapters are required. Buyers who need a higher capacity pack or a different voltage will not be served by this model.

Questions about this item

How do I fit the DS-CS-JBE400SL into my JBL Tune 500BT, and which step catches people out?

Open the ear-cup, unplug the old pack, and connect the new one matching the red and black leads; the common mistake is reversing the polarity.

What maintenance will this 3.7 V 600 mAh Li-Polymer cell need later?

No routine maintenance is required; store at about 50 % charge if the headset is unused for weeks, and avoid full discharge.

What limit appears first during a long listening session with this 2.22 Wh battery?

The 600 mAh capacity sets the play-time ceiling; once the voltage drops to the headset's cut-off point the audio stops.
