About this replacement
Samsung Galaxy Tab A 8.0 2017 — 3.7V Li-Polymer Replacement Battery (EB-BT367ABA)
This 3.7V, 3500mAh lithium-polymer cell replaces the original battery in the Samsung Galaxy Tab A 8.0 2017 and related variants, including TD-LTE and WiFi models. OEM part numbers EB-BT367ABA, EB-BT367ABE, and GH43-04539A all cross to this cell. Install it when the original no longer holds a charge or fails to power the tablet on.
- Galaxy Tab A 8.0 2017 platform fit: The WiFi, TD-LTE, and base Galaxy Tab A 8.0 2017 variants all share the same battery bay dimensions, connector pinout, and charge IC handshake — one cell covers the full lineup without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Galaxy Tab A 8.0 2017 unit. The BMS accepted the charge IC handshake cleanly on first connection, with no fault flags during either the constant-current or constant-voltage phase.
- Fuel gauge reset after installation: After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without unplugging early. This single full cycle forces the fuel gauge IC to recalibrate against the new cell and clears inaccurate percentage readings that appear immediately after a swap.
Galaxy Tab A 8.0 shutting down at 15–25% remaining after battery replacement
This happens because the fuel gauge IC still holds calibration data from the old, degraded cell. The tablet interprets a voltage drop — caused by the combined load of the display and active WiFi — as a critically low state that triggers shutdown. The new cell actually has charge remaining at that point, but the gauge doesn't know it yet. One full discharge-to-shutoff followed by an uninterrupted charge to 100% resets the calibration and resolves the early cutoff.
Fast charging unavailable on Galaxy Tab A 8.0 after swapping the battery
Samsung's adaptive fast charge protocol requires the charge IC and battery to complete at least one full accepted charge cycle before the device enables higher charge rates. Immediately after a swap, the tablet defaults to standard 5V charging as a precaution. Plug in using the original Samsung charger and cable, let the tablet charge fully without interruption, and fast charge should activate on the following charge cycle. If it still doesn't appear, verify the cable supports USB 2.0 data lines — charge-only cables block the USB-PD negotiation handshake.
