Dell Latitude 15 9510 Compatible Battery 7.6V 6750mAh

Dell Latitude 15 9510 — 7.6V Li-Polymer Replacement Battery (08NFC7)

This 7.6V Li-Polymer cell replaces the original 08NFC7 battery in the Dell Latitude 15 9510 series. It carries 6750mAh (51.3Wh) capacity and fits the WPK5N, 41GJW, HKVNY, TFG1C builds along with over 40 additional Latitude 15 9510 variants. Cross-reference your OEM part number against 08NFC7, HYMNG, N2NLL, N7HT0, NTHT0, YMX3G, or V5K68 before ordering.

• Latitude 15 9510 series compatibility: Every Latitude 15 9510 variant listed here shares the same two-cell Li-Polymer configuration, 7.6V nominal rail, and three-pin smart connector. The BMS handshake protocol is identical across these builds, so one cell fits the full range without hardware modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Latitude 15 9510 unit. The BMS communicated state-of-charge correctly to the OS, charge termination triggered at the right voltage ceiling, and no overcurrent fault codes were thrown during high-CPU load draws.
• BIOS learn cycle after installation: After fitting this cell, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100% without using the laptop. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on the 9510 platform.

Why the Latitude 15 9510 shuts down at 20–30% remaining after a battery swap

The fuel gauge IC on the 9510 mainboard builds its discharge curve from data logged by the previous cell. When a new cell goes in, that curve no longer matches real chemistry, so the gauge reports critically low charge while actual cell voltage is still healthy. Under full CPU plus display load, the mismatch triggers an emergency shutdown before the new cell is genuinely depleted. Running two or three full charge-discharge cycles recalibrates the fuel gauge IC against the new cell's actual voltage profile and eliminates the premature cutoff.

New cell not charging above 80% on the Latitude 15 9510

Dell's BIOS ships with a battery charge limit feature that caps charging at 80% by default when "Primary AC Use" mode is active in the Dell Power Manager settings. This is a firmware control, not a fault with the replacement cell. Open Dell Power Manager, navigate to Battery Settings, and switch the charge mode to "Adaptive" or "Full Charge." The cell will then charge to its full 51.3Wh capacity — confirm this in Settings → System → Battery or by checking reported Wh in the BIOS hardware inventory screen.
