About this replacement
Samsung Galaxy Tab A 10.5 2018 — 3.8V Li-Polymer Replacement Battery (EB-BT595ABE)
This is a 3.8V, 7300mAh Li-Polymer replacement battery for the Samsung Galaxy Tab A 10.5 2018. It fits the SM-T590 and SM-T595 variants, including the TD-LTE model. Install it when the original cell no longer holds charge or the tablet shuts down unexpectedly during use.
- SM-T590 and SM-T595 compatibility: Both variants run the same 3.8V battery rail and use the same flex connector and BMS handshake. The EB-BT595ABE part number covers the full SM-T59x series, so one cell fits both the Wi-Fi and LTE builds without modification.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the SM-T590 platform. The BMS accepted the new cell without error flags, and the charge IC stepped through trickle, CC, and CV phases cleanly at both standard and adaptive fast charge rates.
- Fuel gauge recalibration after swap: After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to map its calibration curve against the new cell, which corrects the inaccurate percentage readings that commonly appear immediately after a replacement.
Galaxy Tab A 10.5 shutting down at 15–25% remaining
When the display and Wi-Fi radio run simultaneously, combined current draw pulls the cell voltage down sharply — faster than the fuel gauge predicts. If the gauge IC is calibrated to a degraded old cell, it misjudges the remaining capacity and triggers shutdown well above 0%. The fix is a full recalibration cycle: discharge to automatic shutoff with screen and Wi-Fi active, then charge to 100% without interruption. After one clean cycle, the gauge re-anchors its low-voltage cutoff threshold to the actual cell curve, and shutdowns at 15–25% stop occurring.
Fast charging not available after battery replacement
Samsung's adaptive fast charge protocol requires a completed accepted charge cycle before the charge IC confirms the cell profile and unlocks higher charging rates. On a fresh cell, the controller defaults to standard charging for the first cycle as a precaution. Plug in using the original Samsung charger and cable — third-party cables frequently lack the correct resistance values for USB-PD negotiation on this platform. After one full charge to 100%, fast charging becomes available and remains active on subsequent cycles.
