DELL WDX0R 42Wh Laptop Battery 11.4V for Inspiron & Latitude

This is a 100% new DELL WDX0R 3‑cell Li‑ion Polymer laptop battery providing 42Wh (11.4V) power compatibility for a wide range of Inspiron and Latitude models.

If your Dell notebook is running short on runtime, shutting down unexpectedly, or showing battery errors, this WDX0R replacement restores battery life with Grade A cells and built‑in circuit protection. Designed as a direct replacement for original Dell part numbers such as WDX0R, 0WDX0R and several OEM codes, it offers the same voltage and form factor as the factory pack so installation is straightforward for most models listed below.

Which Dell laptops will this WDX0R battery work with?

This battery is compatible with many Inspiron and select Latitude systems that accept a 3‑cell 11.4V pack. Always confirm your current battery model by checking the service label inside the laptop before ordering.

• Compatible models include multiple Inspiron 15, 13 and 17 series (for example 7579, 7560, 7580, 5570, 5770) and some Latitude 3189/3580 units.
• Matches OEM part numbers: WDX0R, WDXOR, 0WDX0R and alternate codes listed on the product page.
• For Inspiron 7586, verify the battery model under the bottom cover because three different packs are used for that chassis.

How long will this replacement battery last on a single charge and over time?

Runtime depends on your configuration and workload; typical web browsing and light tasks yield several hours. Constructed from Grade A cells, this pack is rated for 500+ charge cycles under normal conditions, preserving capacity longer than worn OEM batteries.

• Capacity: 42Wh (3500mAh) at 11.4V—suitable for everyday productivity.
• Grade A lithium‑ion polymer cells for stable voltage delivery and consistent runtime.
• Factory tested to ensure reliable cycle life and performance out of the box.

Is this WDX0R battery safe and easy to install?

This replacement includes multi‑protect safety circuitry and overcurrent/overcharge protection to reduce risk and help safeguard your laptop. Installation is typically a simple battery swap if you follow the laptop’s service instructions and use the correct tools.

• Built‑in circuit protection guards against short circuits, overcharge and excessive discharge.
• Form factor and connector match the original for a drop‑in replacement in compatible models.
• Follow manufacturer guidance: power off, remove external power, and discharge static before opening the chassis.

What should I check before buying this battery for my Dell?

Measure compatibility by comparing model numbers and the shape/connector of your installed battery. For certain Dell models (notably Inspiron 7586), multiple battery variants exist—confirm which variant is in your laptop first.

• Open the laptop’s bottom cover and read the battery model label to ensure it lists WDX0R or a matched part number.
• Confirm voltage (11.4V) and cell count (3 cells) to match the replacement pack.
• Check the seller’s compatibility list and read notes for models that accept multiple battery types.

Who is this for: This WDX0R replacement battery is intended for Dell owners with compatible Inspiron or Latitude notebooks who want a reliable, factory‑tested replacement to restore portability and runtime. It’s a good choice for users replacing an aged or failing battery who prefer a direct, OEM‑form replacement rather than a larger aftermarket pack. If you’re unsure which battery fits your laptop, inspect the battery label under the bottom cover or consult your service manual before purchasing.
