Samsung Galaxy A7 2016 Duos EB-BA710ABE Compatible Battery 3.85V 3300mAh

Samsung Galaxy A7 2016 Duos — 3.85V Li-ion Replacement Battery (EB-BA710ABE)

This is a 3.85V, 3300mAh Li-ion cell built to replace the original EB-BA710ABE battery in the Samsung Galaxy A7 2016 Duos. It fits the SM-A710, SM-A710M/DS, and SM-A7100 series. The cell matches the original voltage rail and connector position, so no modification is needed during installation.

• SM-A710 series compatibility: The SM-A710, SM-A710M/DS, and SM-A7100 all share the same battery bay geometry, connector pinout, and BMS handshake protocol. Samsung used a single battery spec across this regional variant lineup, so one part number covers all of them.
• Bench tested on actual hardware: We ran this cell on an SM-A710 unit and confirmed the BMS accepted the new cell without throwing a battery health warning. The charge IC ramped normally through CC and CV phases, and the protection circuit tripped correctly at the expected low-voltage cutoff threshold.
• Fuel gauge recalibration on first use: After fitting this cell, disable fast charging and run one full discharge-to-charge cycle at standard current. The Galaxy A7's fuel gauge IC was calibrated to the old cell's discharge curve — one slow cycle lets it map the new cell before high-current charging begins.

Sudden shutdown at 20–30% on the Galaxy A7 after a cell swap

This is a voltage cliff issue, not a defective battery. The SM-A710's Snapdragon 410 and the AMOLED display draw a combined current spike that a freshly installed, uncalibrated cell briefly cannot sustain. Voltage drops below the system's cutoff threshold even though the fuel gauge still shows charge remaining. The phone interprets the voltage dip as empty and shuts down. Running two full discharge-charge cycles at standard current lets the BMS and fuel gauge IC align, and the shutdowns stop.

Galaxy A7 not powering on after the replacement cell sat in storage

Li-ion cells ship at a partial charge, typically around 30–50%. If the phone sat unused for weeks after receiving it, the cell may have self-discharged below 2.5V — the BMS lockout threshold. At that point, the phone shows nothing when you press power. Connect the original Samsung charger and leave it for 20–30 minutes without pressing any button; the charge IC will trickle-charge the cell until the BMS re-initialises at approximately 3.0V, after which the phone will boot normally.
