Replacement battery for Galaxy Buds 3 Pro

The Cameron & Co DS-CS-SMR630SH is a lithium-polymer cell built to replace the EB-BR630ABY in Samsung Galaxy Buds 3 Pro earbuds. It delivers 3.88V and 500mAh for 1.94Wh of capacity. The pack measures 30.70 x 21.00 x 5.50 mm and comes in black. It is sold new and rated 100% OEM compatible.

Installation notes and common issues

Replacing the cell requires opening the sealed earbud housing, which demands fine tools and steady hands. The flex connector must be aligned precisely; forcing it can tear the ribbon or damage the mainboard. Adhesive residue often remains after removing the old pack and must be cleaned before fitting the new one. Improper resealing can compromise water resistance.

Check before ordering

Confirm your earbuds are the SM-R630N Galaxy Buds 3 Pro model. Verify the original battery part number matches EB-BR630ABY exactly. Ensure you have the necessary micro-soldering or connector-handling experience, as the repair is not user-serviceable by design. This battery is not suitable for other Samsung earbud models or charging cases.
