About this replacement
Samsung Galaxy Tab S2 8.0 — 3.8V Li-Polymer Replacement Battery (EB-BT710ABA)
This is a 3.8V, 3500mAh Li-Polymer battery for the Samsung Galaxy Tab S2 8.0. It fits SM-T710, SM-T715, SM-T715N0, and related variants on the same platform. Use it when the original EB-BT710ABA has degraded, swells, or no longer holds a charge.
- SM-T710 and SM-T715 platform fit: Both Wi-Fi and LTE variants of the Tab S2 8.0 share the same battery footprint, connector pinout, and charge IC handshake. The EB-BT710ABA and EB-BT710ABE are interchangeable OEM references for the same cell configuration across this range.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an SM-T710 unit. The BMS accepted the charge IC handshake without errors, voltage held steady across display-on and Wi-Fi active states, and the protection circuit triggered cleanly at the low-voltage cutoff threshold.
- Fuel gauge reset after installation: After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to recalibrate against the new cell and clears the inaccurate percentage readings that typically appear immediately after a swap.
Tab S2 8.0 shutting down between 15% and 25% remaining
This is a voltage cliff issue, not a defective cell. When the display backlight and Wi-Fi radio draw current simultaneously, the combined load pulls cell voltage down faster than the fuel gauge IC can track. The OS reads a percentage derived from a voltage curve calibrated to the old, degraded cell. Once actual cell voltage drops below the BMS protection threshold — around 3.0V under load — the tablet shuts off even though the percentage display still shows capacity remaining. Running one full discharge-to-shutoff cycle and a complete uninterrupted recharge resets the calibration curve and eliminates the early cutoff.
Fast charging not available after battery swap on SM-T710
Samsung's adaptive fast charge protocol requires the charge IC to complete at least one full accepted charge cycle before the tablet re-enables higher charge rates. Immediately after a swap, the system defaults to standard 5V charging as a precaution. This is not a fault with the replacement cell. Connect the tablet to the original Samsung fast charger, let it charge fully to 100% without interruption, and fast charge will be available from the next session onward.
