Cameron & Co DS-CS-SMA515SL cell phone battery 3900mAh 3.85V Li-Polymer black

Replacement battery for Galaxy A51 2019

This Cameron & Co DS-CS-SMA515SL cell phone battery is a direct replacement for the Samsung Galaxy A51 2019 series, including models SM-A515F/DSM, SM-A515F/DSN, SM-A515F/DST, SM-A515F/N, SM-A515G, SM-A515U and SM-A516. It matches the original EB-BA515ABE and EB-BA515ABY part numbers. The 3900mAh Li-Polymer cell restores factory runtime for owners whose original pack no longer holds a charge. It is not suited to any other handset or tablet.

Li-Polymer chemistry and fixed voltage

The pack delivers 3.85V nominal voltage and 15.02Wh rated energy, fixed by the lithium-polymer chemistry. Capacity cannot be expanded beyond the stated 3.9Ah, and the cell has no built-in charge controller; the phone manages all charging and safety logic. Users needing higher capacity or a different voltage must choose a different device, as this battery is electrically locked to the A51 platform.

Slim black pack with OEM footprint

Measuring 75.85 x 62.72 x 4.54mm, the black Li-Polymer pouch slides into the existing battery cavity without adapters or shims. The thin profile means the rear cover seats flush, preserving the original hand feel and water-resistance seals when reassembled correctly. Build quality follows OEM tolerances, so connector alignment and thermal contact match the factory unit. There are no mounting brackets, screws or cables included.
