Replacement Battery for Dell Latitude and Precision

This 64Wh lithium-ion unit operates at 15.2V and replaces part numbers including 41CP7/54/64, GRT01 and 00P3TJ. It fits Latitude 14 5421 and 5431 models, Latitude 15 5521 and 5531 models, plus Precision 15 3561 and 3571 systems. The black pack ships new with a twelve-month warranty.

Installation Notes and Common Issues

The battery sits in the standard internal bay and connects with the original cable; no extra tools are required beyond a small Phillips driver. Builders should disconnect the AC adapter and hold the power button for a few seconds before starting. Misaligned connectors or forgotten cable routing are the usual causes of a no-post condition.

Capacity and Runtime Expectations

At 64Wh the pack delivers typical mobile-workstation runtime for office applications, web browsing and video playback. Heavy loads such as sustained rendering or gaming will drain the cell faster, and the 15.2V rail cannot support configurations that demand a higher voltage. Buyers needing extended field use without mains power should plan for a second pack.

Questions about this item

How can I confirm the 64Wh 15.2V battery is working correctly after installing it in my Latitude 5421?

What comes in the package and is anything else needed for installation?

The box contains one black lithium-ion battery; no screws, cables or tools are included, so reuse the hardware from the old pack.

My part number is 41CP7/54/64 — which listed version matches this exactly?

The product is sold as a single 64Wh 15.2V unit under part numbers GRT01, 41CP7/54/64, 00P3TJ, 0P3TJ, 0R05P0, R05P0 and 05RGW, all referring to the same specification.
