JIAZIJIA DR02P Laptop Battery 11.4V 54Wh for Dell

JIAZIJIA DR02P is a direct-fit 11.4V, 54Wh lithium-ion replacement battery designed to restore runtime for selected Dell Latitude, Precision and Inspiron 14 Plus models.

If your Dell laptop is losing charge quickly or will not power on without the adapter, this compatible DR02P pack offers a straightforward plug-and-play swap. It replicates the original battery's voltage and capacity (11.4V / 54Wh, 4623mAh) and matches multiple OEM part numbers so you can find the right fit without guessing. The unit ships in black and is intended for users who prefer an affordable, like-for-like replacement instead of buying a new laptop.

Which Dell models and part numbers does this battery replace?

The JIAZIJIA DR02P is engineered to match several Dell model families and multiple OEM replacement codes. Check the part number printed on your existing battery before ordering to ensure compatibility.

• Compatible model families: Latitude 3340 / 3440 / 3450 / 3540 / 3550 / 5340 / 5350 / 5440 / 5450 / 5540 / 5550 / 7455.

How easy is installation and what should I check first?

Installation is intended to be simple: remove the laptop's back cover, unplug the old battery, then install the replacement and reassemble. Because battery designs and internal layouts vary by model, verify the label on your existing battery to confirm the exact model number before starting.

• Open the back case with appropriate tools and find the battery label for model verification.
• Power off the laptop and disconnect any power source before replacing the battery.
• Follow included manual guidance and use anti-static precautions during installation.

What performance can I expect and is it safe to use?

This JIAZIJIA battery provides the same nominal voltage and rated capacity as the original 54Wh pack, so you should regain near-original runtime under similar workloads. It is a lithium-ion design intended for the specified systems and includes standard safety features, but avoid using damaged batteries or exposing them to extreme heat.

• Rated capacity: 54Wh / 4623mAh at 11.4V for comparable operating time to the factory cell.
• Plug-and-play design — no special drivers required after physical installation.
• Observe normal battery safety: do not puncture, short-circuit, or immerse in liquid.

Will this battery affect system warranty or battery reporting?

Replacing a battery typically does not void the laptop's main warranty, but policies vary by manufacturer and region. After installing a third-party pack, the operating system may show a generic or third-party battery name in the power manager while still reporting charge level and health metrics.

• Check Dell warranty terms or contact support if concerned about service coverage.
• Windows battery reports will display charge cycles and remaining capacity; results depend on usage.
• Keep the original battery and packaging until you confirm stable operation, if possible.

Who is this for: The JIAZIJIA DR02P replacement battery is aimed at Dell owners who need a cost-effective, direct-fit battery swap for selected Latitude, Precision, and Inspiron 14 Plus models. It's suitable for students, professionals, IT technicians, and anyone who wants to restore portable runtime without replacing the entire laptop. Confirm your original battery's part number, follow the installation instructions, and this pack can return reliable on-battery use to compatible systems.
