Cameron & Co DS-CS-SMT307SL Battery

This replacement battery fits the Samsung Galaxy Tab A 8.4 2020 model SM-T307U. It matches the original EB-BT307ABY part and uses a lithium-polymer cell rated at 4.8 Ah and 18.48 Wh. The pack is intended for owners who need a direct swap without adapter cables or firmware changes. Buyers with other tablet models or larger capacities should look elsewhere.

Sustained load behaviour

The 4800 mAh cell delivers a steady 3.85 V output during extended use such as video playback or web browsing. Capacity holds across the full discharge curve rather than dropping sharply after a short burst. The lithium-polymer chemistry resists voltage sag under moderate continuous draw typical of tablet workloads. Users who run high-drain applications for many hours will see a gradual decline consistent with the rated watt-hours.

Thermals noise and power draw

The slim 3.00 mm profile fits inside the original chassis without forcing the back cover or stressing connector ribs. No moving parts mean silent operation and zero fan noise in any scenario. Self-discharge is low when the tablet is idle, preserving stored charge between sessions. Heat stays within normal hand-warm limits during typical charging and discharging cycles.

Questions about this item

Does the 3.85 V 4800 mAh Li-Polymer cell run warm or draw extra power during all-day use?

The 4.8 Ah pack is a direct replacement for the original EB-BT307ABY, so it draws the same current and produces the same heat as the factory battery under normal tablet workloads.

What tools or parts must I already have to install this 103.26 × 99.70 × 3.00 mm pack in my Galaxy Tab A 8.4 2020?

You need standard phone-opening tools — heat gun or iOpener, suction handle, plastic picks and a small Phillips driver — plus adhesive strips to reseal the back glass after the swap.

Will this 18.48 Wh replacement work alongside the original charging board and fuel-gauge circuitry in an SM-T307U?

Yes, the cell matches the OEM voltage and capacity exactly, so the existing charge controller and battery-management IC recognise it without any firmware change.
