Dell Precision 5680 Replacement Battery 11.55V 8600mAh

Up to 19% off
New arrival
From $108.99 USD $134.99
Shipping calculated at checkout.
Fits Dell Precision 5680 and 5690 mobile workstations, replacing OEM part numbers 6D2HW, KV690, N7KV9, and WPYCV.
Nominal voltage is 11.55V at 8600mAh capacity (99.33Wh total); this matches the original pack for sustained CPU and GPU workloads on portable use cycles.
Connector is a standard four-pin JST interface with keyed polarization; the battery slides into the bottom chassis slot and locks with a pull-tab at the hinge edge.
We bench-tested this cell on a Precision 5680 charge circuit; the BMS accepted the pack on first insertion and held voltage steady through a full CPU load without early cutoff.
After installation, discharge the machine to hibernate-cutoff, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Dell Precision 5680 / 5690 — 11.55V Li-Polymer Replacement Battery (6D2HW)

This is an 11.55V, 8600mAh (99.33Wh) lithium-polymer replacement battery for the Dell Precision 5680 and Precision 5690 mobile workstations. It slots into the internal bay and restores portable operation when the original cell has degraded or failed. OEM cross-references include 6D2HW, KV690, N7KV9, and WPYCV.

  • Precision 5680 and 5690 compatibility: Both models run the same 11.55V battery rail with an identical physical connector and BMS handshake protocol. One cell covers both platforms without modification.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on a Precision 5680 chassis. The BMS negotiated correctly with the EC firmware — no error flags, no charge interruption, and the fuel gauge IC initialized without a manual reset.
  • Post-install calibration on the Precision 5680: After fitting, run one full discharge to the hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

BIOS reporting poor battery health after installing a new cell

Dell's BIOS reads health data stored in the battery's EEPROM. When a new cell ships, that EEPROM contains factory defaults that don't match the host system's learned charge history. The EC interprets the mismatch as a degraded or unknown battery. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS learn cycle to rewrite against the new cell's actual data. After two to three cycles, the health status in Dell Power Manager corrects itself.

Precision 5680 shutting down abruptly at 20–30% charge shown

This happens when the cell voltage drops below a sustainable threshold under combined CPU and display load — faster than the fuel gauge IC can track. The gauge was calibrated against the old, degraded cell and has not yet learned the new cell's discharge curve. The system hits the EC's undervoltage cutoff while the OS gauge still shows charge remaining. Run two full calibration cycles — discharge to hibernate cutoff, then charge to 100% without interruption — and the gauge IC recalibrates to the new cell's voltage profile.

Frequently Asked Questions

Dell Power Manager shows the new battery as "Unknown" or 0% — why won't it read correctly?

The BIOS pulls health and identification data from the EEPROM on the battery controller. A new cell ships with factory defaults that the host EC has never seen, so it flags the battery as unknown until it completes a learn cycle. Discharge the laptop fully until it hibernates, then charge uninterrupted to 100% without using the machine. After one complete cycle, Power Manager should display the correct percentage and health status.

The fuel gauge is jumping around — shows 60%, then 45%, then back to 55% within minutes of use.

The fuel gauge IC inside the battery calculates state-of-charge by tracking voltage and current against a stored discharge model. That model is built from the previous cell's chemistry data, so readings are unstable until the IC recalibrates against the new cell. Run two full cycles — discharge to hibernate, then charge to 100% uninterrupted — on a cool, flat surface with no heavy workloads running. By the third cycle, the gauge IC locks onto the new cell's curve and readings stabilize.

System info shows 84Wh for this battery but the spec says 99.33Wh — is the cell faulty?

This is an EEPROM data mismatch, not a faulty cell. Dell's EC reads the rated Wh figure from the battery's EEPROM, and the value stored at the factory may reflect a different capacity variant in the same product family. The actual electrochemical capacity of the cell is 99.33Wh as rated. To confirm, check the physical label on the battery itself — if it reads 99.33Wh, the cell is correct and the EEPROM figure will update after the BIOS completes its battery learn cycle.
