Direct replacement for Dell Precision and Latitude
The TOPKTEAM R05P0 GRT01 is a new lithium-ion battery rated at 15.2V and 64Wh with a 4000mAh capacity. It is engineered to fit select Dell Precision and Latitude mobile workstations. Buyers needing a different voltage or a higher watt-hour rating will not be served by this unit.
Black lithium-ion pack
The pack uses a black lithium-ion cell assembly terminated by the proprietary Dell interface required by the listed models. No cables or adapters are included because the battery slots directly into the chassis bay. Systems outside the Precision 3470, 3561, 3571, 3581 and Latitude 5421, 5431, 5521, 5531, 5531 ranges cannot accept this connector.
Ready to install without extra tools or software
The box contains only the battery itself; there are no mounting screws, driver discs or calibration utilities supplied. Installation is a mechanical swap that the laptop firmware recognises immediately. Users who expect bundled hardware or a software suite for battery management will need to source those separately.
