OUWEE Laptop Battery for Dell XPS 15 9575 / Precision 5530

OUWEE 8N0T7 is a direct-replacement lithium-ion battery designed to restore full mobile runtime to compatible Dell XPS 15 9575 and Precision 5530 2-in-1 notebooks.

If your Dell 2-in-1 runs out of power sooner than it used to or won't hold charge, this OUWEE replacement battery matches the original battery’s 11.4V voltage and 75Wh (6254mAh) capacity to deliver comparable operating time. It fits machines using the 8N0T7 / 08N0T7 / TMFYT / 0TMFYT part numbers and installs with the same connector layout as the factory pack. The cell chemistry is Li-ion and the pack contains six cells arranged for balance between energy density and thermal performance.

How do I confirm this battery fits my Dell laptop?

Check the service tag and part number on your existing battery or in Dell’s documentation before ordering. OUWEE lists compatibility with XPS 15 9575 2-in-1 and Precision 5530 2-in-1 series, and the included part numbers help match factory packs.

• Verify your old battery shows 8N0T7, 08N0T7, TMFYT, or 0TMFYT.
• Compare the connector orientation and cable length to the product photos.
• Confirm your laptop model: Dell XPS 15 9575 or Dell Precision 5530 2-in-1.

What performance and safety features does this 75Wh Li‑ion pack offer?

This replacement provides the same nominal voltage (11.4V) and total energy (75Wh/6254mAh) as the original pack for consistent runtime. It uses Li-ion cells with standard protections built into the battery pack to guard against overcharge, over-discharge and short circuits when used as intended.

• Nominal voltage: 11.4V for compatibility with factory power circuitry.
• Capacity: 75Wh (6254mAh) to match expected run times.
• Pack protections included to support safe charging and discharging.

How should I install and prepare the new battery for best results?

Installation is straightforward but requires care: power down the laptop, remove the back cover, disconnect the old pack, and secure the OUWEE unit in the same orientation. If the new battery isn’t recognized immediately, reseat the connector and repeat installation. Conditioning the pack with a few charge/discharge cycles helps the battery management system calibrate reported charge levels.

• Power off and unplug the laptop before opening the chassis.
• Disconnect and remove the old battery, then connect the OUWEE pack firmly.
• If not recognized, discharge to ~5% and recharge fully 3–4 times to calibrate.

What differences should I expect from third-party batteries compared to OEM?

Third-party replacement batteries like the OUWEE 8N0T7 are engineered to match OEM voltage and capacity but may vary in cosmetic details such as cable length or sticker placement. Quality and compatibility depend on correct part-number matching and careful installation; always compare physical connectors and dimensions before purchase.

• Electrical specs match OEM: 11.4V and 75Wh capacity.
• Physical differences may include cable length or label position.
• Follow manufacturer guidance for initial conditioning and installation.

Who this is for: The OUWEE 8N0T7 cell pack is aimed at owners of Dell XPS 15 9575 and Precision 5530 2-in-1 notebooks who need a cost-effective, like-for-like battery replacement. It suits users seeking to restore mobility and uptime without buying a full new machine—particularly technicians, mobile professionals, and anyone comfortable opening their laptop to swap the internal pack following safety precautions.
