Samsung Galaxy C5 Replacement Battery EB-BC500ABE 3.85V

Samsung Galaxy C5 / SM-C5000 — 3.85V Li-Polymer Replacement Battery (EB-BC500ABE)

This is a 3.85V, 2600mAh Li-Polymer replacement battery for the Samsung Galaxy C5 and Galaxy C5 Duos TD-LTE (SM-C5000). OEM part numbers EB-BC500ABE and EB-BC500ABA both cross-reference to this cell. It fits all variants in the C5 lineup that share the original Samsung connector and BMS handshake.

• C5 and C5 Duos compatibility: The SM-C5000 single-SIM and the C5 Duos TD-LTE use the same battery bay, connector pinout, and BMS communication protocol. Both variants accept this cell without modification.
• Bench tested on actual hardware: We cycled this battery on an SM-C5000 mainboard and confirmed the BMS handshake completed correctly — the charge IC accepted the cell, the fuel gauge IC began tracking, and no charge-fault flags were raised.
• Fuel gauge recalibration on first install: After fitting this cell, disable Samsung Adaptive Fast Charging for the first full discharge-to-charge cycle. The Galaxy C5's fuel gauge IC is calibrated to the original cell's discharge curve. One standard charge cycle lets it recalibrate before high-current charging pushes current into an uncalibrated cell.

Sudden shutdown at 20–30% on the Galaxy C5 after a cell swap

The Galaxy C5 shuts down mid-use despite the status bar showing charge remaining because the fuel gauge IC is still mapping the old cell's voltage-to-capacity curve. A new Li-Polymer cell has a slightly different discharge curve — the point where voltage drops sharply under modem or display load sits at a different state-of-charge than the IC expects. When the CPU draws a burst and cell voltage dips below the cutoff threshold, the phone cuts power even though the gauge hasn't hit 0%. One full discharge down to automatic shutdown, followed by an uninterrupted charge to 100%, resets the coulomb counter and eliminates these premature cutoffs.

Samsung Adaptive Fast Charging not activating after battery replacement

On the first cycle after a cell swap, the Galaxy C5's charge IC may not negotiate the fast-charge protocol with the replacement cell's BMS. This shows up as the phone charging at standard 5V/1A instead of the higher-voltage fast-charge rate. The BMS on a new cell starts in a cautious state and may require one standard charge cycle before the handshake completes correctly. After that first full cycle, reconnect the charger — Adaptive Fast Charging should activate and the notification shade will confirm it at 9V.
