Direct replacement for JBL Free charging case

This Cameron Sino DS-CS-JBT100SL battery fits the JBL Free Truly charging case and replaces part number GSP853450 01. It delivers 3.7 V and 1200 mAh capacity in a lithium-polymer cell. The pack measures 69.30 x 30.00 x 7.10 mm and comes in black. It is sold as a single unit.

Restores original runtime for the case

Swapping the cell returns the charging case to its factory 4.44 Wh energy rating. The upgrade is worth it when the original battery no longer holds enough charge for a full day of earbud top-ups. No soldering or case modification is required for installation.

One earbud cycle per full charge

At 1.2 Ah the pack comfortably handles one complete recharge of both earbuds. It runs out when the case itself needs recharging from a USB source. Buyers who want multiple earbud charges without plugging the case in will need a higher-capacity power bank instead.

Questions about this item

Will the 69.30 x 30.00 x 7.10 mm battery fit inside the JBL Free Truly charging case?

Yes, those dimensions match the original GSP853450 01 cell so it sits in the case without modification.

What is the correct polarity when inserting the DS-CS-JBT100SL into the charging case?

Align the cell so its positive and negative contacts meet the case terminals exactly as the old battery did; reversing them prevents charging.

When should the 3.7 V 1200 mAh Li-Polymer pack be replaced?

Replace it when the case no longer holds a full 4.44 Wh charge or the earbuds drain noticeably faster than when the battery was new.
