About this replacement
Samsung Galaxy Tab A 10.1 — 3.8V Li-Polymer Replacement Battery (EB-BT585ABA)
This is a 3.8V, 6000mAh Li-Polymer replacement battery for the Samsung Galaxy Tab A 10.1 (2016). It fits the SM-T580 and SM-T585, covering both the WiFi-only and TD-LTE variants. Direct swap for the original EB-BT585ABA when the existing cell no longer holds adequate charge for daily use.
- SM-T580 and SM-T585 compatibility: Both the WiFi and LTE versions of the Galaxy Tab A 10.1 (2016) use the same battery housing, connector, and BMS handshake protocol. The cell voltage, physical dimensions (144.80 × 119.30 × 3.50mm), and charge IC communication are identical across both SKUs.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on an SM-T585 unit. The BMS accepted the initial charge without fault codes, and the charge IC communicated correctly with the board through the full cycle.
- Fuel gauge recalibration after install: After fitting this battery, run the tablet down to automatic shutoff — do not force-shutdown — then charge uninterrupted to 100%. This single full cycle resets the fuel gauge IC against the new cell and clears the inaccurate percentage readings that commonly appear after a swap.
Why the Galaxy Tab A 10.1 shuts down at 15–25% remaining
Under combined load — screen at full brightness, active WiFi, and background sync — the Tab A 10.1 draws enough current to create a voltage sag the fuel gauge IC misreads as a near-empty cell. The board triggers a protective shutdown before the actual cell capacity is exhausted. This happens more often with a degraded original battery, but also appears with a new cell if the fuel gauge has not been recalibrated. Running one full discharge-to-shutoff cycle after installation corrects the gauge reference point and eliminates most early-shutdown events.
Fast charging unavailable after battery replacement on SM-T580
The Tab A 10.1 uses Samsung's Adaptive Fast Charging protocol, which requires the charge IC to complete at least one accepted charge handshake before the device enables higher charge rates. Immediately after a battery swap, the controller may default to standard 5V charging while it re-establishes this negotiation. Plug in the original Samsung charger — not a generic USB-C adapter — and allow a full uninterrupted charge to 100%. Fast charge availability typically restores on the second or third cycle once the protocol handshake is confirmed.
