About this replacement
Samsung Galaxy Tab 10.1 GT-P7510 — 3.7V Li-Polymer Replacement Battery (SP3676B1A)
This is a 3.7V, 6000mAh Li-Polymer battery for the Samsung Galaxy Tab 10.1. It fits the GT-P7510 and extends to the GT-N8000 and GT-7511 — all tablets that share the SP3676B1A cell configuration. Capacity figures come from the product data: 6000mAh, 22.2Wh.
- GT-P7510 and GT-N8000 compatibility: These models share the same 3.7V single-cell rail, identical connector pinout, and the same BMS handshake protocol. Swapping between them does not require firmware changes or connector adapters.
- Bench tested on actual hardware: We ran this cell in a GT-P7510 unit and monitored BMS behaviour through a full charge cycle. The protection circuit responded correctly to charge termination at 4.2V and flagged low-voltage cutoff at 3.0V without tripping prematurely.
- Fuel gauge recalibration after swap: After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to recalibrate against the new cell's actual capacity curve and clears the inaccurate percentage readings that appear immediately after installation.
GT-P7510 shutting down at 15–25% remaining
This is a voltage cliff issue, not a defective cell. When the display backlight and WiFi radio draw current simultaneously, the combined load pulls the cell voltage below the BMS cutoff threshold faster than the fuel gauge can track. The OS reads 20% remaining but the cell is already at 3.0V under load. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% recalibrates the gauge and eliminates most premature shutoffs.
Fast charging unavailable after battery replacement on GT-P7510
The GT-P7510 uses a proprietary charge handshake — if the charge IC on the new cell hasn't completed one accepted charge cycle, the tablet defaults to standard 5V charging instead of negotiating the higher rate. This shows up as a slow charge indicator even with the original charger. Charge the tablet fully from flat once using the Samsung OEM charger. After that cycle completes, the fast-charge negotiation re-establishes correctly.
