Dell Vostro 3510 15.2V Replacement Battery JGCCT 57.76Wh

Dell Vostro 3510 / 5510 Series — 15.2V Li-Polymer Replacement Battery (JGCCT)

This 15.2V, 3800mAh (57.76Wh) lithium-polymer cell replaces the factory battery in the Dell Vostro 3510, 3515, 5410, and 5510. It matches the original JGCCT, N9XX1, TN70C, and XDY9K part numbers. If your Vostro no longer holds a charge or shuts down unexpectedly, this cell is the direct swap.

• Vostro 3510 / 3515 / 5410 / 5510 compatibility: All four models share the same 15.2V four-cell Li-Polymer architecture, the same physical connector, and the same BMS handshake protocol — which is why a single part number covers the entire group.
• Bench tested on actual hardware: We ran this cell on a Vostro 3510 chassis. The BMS initialised on first boot, BIOS detected the battery without a firmware error, and charge regulation engaged normally through a full cycle.
• First-cycle recalibration after install: After fitting this cell, run the laptop unplugged until it hibernates at the low-battery cutoff, then charge uninterrupted to 100%. This completes the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

Why the Vostro 3510 BIOS reports poor battery health immediately after a swap

The Vostro line stores learned charge data in EEPROM on the original battery's fuel gauge IC. When a new cell goes in, that data is gone. The BIOS reads the blank EEPROM as a degraded or unknown battery and flags it as poor health. This is not a fault with the replacement cell — it resolves after one or two full discharge-charge cycles as the fuel gauge IC builds new baseline data. No driver update or BIOS flash is needed.

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The OS percentage reading is still mapped to the old cell's characteristics, so it looks like 25% remaining when the real cell voltage has already dropped to the cutoff threshold. The fix is the same recalibration cycle — discharge to hibernate cutoff, then charge to 100% without interruption. After two full cycles, the gauge typically tracks within 5% of actual state of charge across the range.
