About this replacement
Samsung Galaxy Tab 4 10.1 — 3.8V Li-Polymer Replacement Battery (EB-BT530FBC)
This 3.8V, 6000mAh Li-Polymer battery replaces the original EB-BT530FBC in the Samsung Galaxy Tab 4 10.1. It fits SM-T530, SM-T537, SM-T537R4, and related variants. Swap this in when the original cell no longer holds a charge or the tablet shuts down unexpectedly under load.
- SM-T530 and SM-T537 series compatibility: These models share the same 3.8V battery rail, physical footprint, and connector orientation. The BMS handshake is identical across the T530 and T537 variants, so one cell covers the full range without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an SM-T530 unit. The BMS accepted the charge IC handshake without fault codes, and voltage under combined display and Wi-Fi load stayed within the expected 3.6–4.2V window.
- Fuel gauge recalibration after swap: After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% before first use. This resets the fuel gauge IC calibration against the new cell and clears the percentage drift that commonly appears after a battery replacement.
Galaxy Tab 4 shutting down between 15–25% remaining
This happens because the old fuel gauge IC calibration does not match the voltage curve of the new cell. When the display and Wi-Fi draw current simultaneously, voltage dips sharply at a lower state of charge than the system expects. The tablet interprets that dip as a critical low and cuts power. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% resets the calibration and eliminates the early cutoff.
Battery percentage jumping or stuck after replacement
The Galaxy Tab 4 stores fuel gauge data tied to the previous cell's internal resistance profile. A new cell has a different resistance curve, so the reported percentage drifts or freezes — often stuck near 50% or jumping 10–15% at a time. This is a software calibration issue, not a fault with the replacement cell. Discharge the tablet fully to automatic shutoff, then charge to 100% in one uninterrupted session — the gauge IC relearns against the new cell's actual voltage floor of approximately 3.4V.
