Replacement Battery for Latitude 2-in-1

This new lithium-ion battery replaces part numbers such as 1WND8 and J0PGR in Dell Latitude 12 5285 and 5290 2-in-1 models. It delivers 11.4V and 31.5Wh capacity using Grade A cells with built-in circuit protection.

Verify Model and Connector Before Fitting

The battery fits Latitude 5285 2-in-1, 5290 2-in-1, 12 5285 2-in-1, 12 5290 2-in-1, T17G, T17G001, T17G002, E5285 and E5290 tablet series. It does not fit the standard Latitude 5290 non-2-in-1 series. Check your existing part number against the compatible list and ensure the connector matches before ordering.

Steady Output Through Full Discharge Cycle

Grade A cells and the integrated protection circuit maintain stable voltage during extended use, reducing the risk of leakage and supporting consistent runtime. For initial calibration, discharge to 5 percent, charge to 95 percent and repeat three to four cycles to reach full capacity.
