About this replacement
Samsung Galaxy Tab A 8.0 2017 — 3.8V Li-Polymer Replacement Battery (EB-BT367ABA)
This 3.8V, 5000mAh Li-Polymer battery replaces the OEM cell in the Samsung Galaxy Tab A 8.0 2017 and its variants, including the TD-LTE and WiFi models. It matches the original connector, dimensions (101.30 × 101.9 × 3.30 mm), and BMS handshake so the tablet's charge IC recognises the new cell. Use this when the original battery no longer holds charge or causes unexpected shutdowns.
- Galaxy Tab A 8.0 2017 variant coverage: The WiFi, TD-LTE, and base Galaxy Tab A 8.0 2017 models all share the same 3.8V power rail, connector pinout, and BMS communication protocol — which is why OEM part numbers EB-BT367ABA, EB-BT367ABE, and GH43-04539A all reference the same physical cell.
- Bench tested on actual hardware: We cycled this battery through charge and discharge on a Galaxy Tab A 8.0 2017 unit. The charge IC accepted the new cell without error flags, and the BMS reported cell voltage correctly across the full charge range.
- Fuel gauge recalibration after swap: After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100% before using the tablet again. The Galaxy Tab A's fuel gauge IC retains calibration data from the old cell — skipping this step causes the percentage indicator to read inaccurately for weeks.
Galaxy Tab A 8.0 shutting down at 15–25% remaining after a battery swap
The Galaxy Tab A 8.0 runs a combined display and WiFi load that draws heavily when both are active. If the fuel gauge IC is still calibrated to the old cell's voltage curve, it misreads the new cell's actual remaining charge. The tablet's firmware triggers a protective shutdown when the reported voltage hits a threshold that no longer matches reality. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% realigns the fuel gauge to the new cell's curve and resolves the early cutoff.
Fast charging not available on the Galaxy Tab A 8.0 after battery replacement
Samsung's Adaptive Fast Charging on this tablet requires the charge IC to complete at least one full accepted charge cycle before enabling higher charge rates on a new cell. If the tablet charges slowly after a swap, it has not yet negotiated the fast charge protocol with the new battery's BMS. Plug into the original Samsung fast charger — not a generic USB-C adapter — and allow a full charge from below 10% to 100% without interruption. After that cycle, fast charging should activate as normal on subsequent charges.
