Samsung Galaxy C910 EB-BC910ABE Replacement Battery 3.85V 3000mAh

Samsung Galaxy C910 / SM-C9100 — 3.85V Li-Polymer Replacement Battery (EB-BC910ABE)

This is a 3000mAh, 3.85V lithium-polymer replacement battery for the Samsung Galaxy C910, SM-C9100, and Galaxy C10 Pro. It replaces OEM part EB-BC910ABE using the same cell format and connector. Capacity figures are taken directly from product data at 11.55Wh.

• Galaxy C910 / SM-C9100 / C10 Pro fitment: These three models share the same battery bay dimensions, 3.85V nominal voltage rail, and EB-BC910ABE connector pinout. No adapter or modification is needed — the BMS handshake uses the same charge termination protocol across the C910 series.
• Bench tested on actual hardware: We cycled this cell on the SM-C9100 and confirmed the BMS accepted the charge profile without fault codes. The protection circuit responded correctly to both charge termination and low-voltage cutoff events during testing.
• Fuel gauge recalibration on first cycle: On first use after installation, disable fast charging and run one complete discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before Samsung's adaptive charging algorithm pushes high current into an uncalibrated cell — preventing erratic percentage readings from the first day.

Why the Galaxy C910 reports wrong battery percentage after a cell swap

The Galaxy C910 uses a coulomb counter IC that builds a discharge model over time against the original cell. When a new cell goes in, the IC still references the old cell's capacity curve, so percentage readings lag or jump. The phone may show 40% and cut out, or climb slowly from 1% even when nearly full. One full uninterrupted discharge down to automatic shutdown, followed by a full charge with the screen off, resets the reference baseline. After that single cycle, percentage accuracy stabilises.

Sudden shutdown at 20–30% on the replacement cell

This is a voltage cliff failure, not a capacity problem. Under modem or display load, the new cell's internal resistance causes a voltage drop that the protection circuit reads as a critical low — even when the coulomb counter still shows charge remaining. The fuel gauge IC has not yet learned where the new cell's voltage floor sits under load. Run the recalibration cycle first: one full discharge to auto-shutoff, then charge uninterrupted to 100%. If shutdowns persist past two full cycles, check that the battery connector is fully seated — a partial connection increases contact resistance and worsens the sag at 3.4V.
