15.2 V 64 Wh Li-ion replacement

This KingSener GRT01 battery replaces the original 4-cell pack in Dell Latitude 5421, 5431, 5521, 5531, Precision 3561, 3571, 3470 and Alienware M17 R5 AMD models. It delivers 15.2 V and 64 Wh using new Li-ion cells. The unit matches the factory dimensions so installation requires no modification. A one-year warranty covers the replacement.

Buyers needing the 11.4 V 97 Wh variant

This part suits owners whose original battery carries the GRT01 or 0R05P0 part numbers and the 15.2 V label. It will not work for systems that require the 9JRV0 11.4 V 97 Wh pack; those two models are not interchangeable. Users who cannot confirm their exact part number should verify before ordering.

Voltage must match 15.2 V exactly

The single specification that decides fitment is the 15.2 V rating printed on the original battery. A 11.4 V unit will not function in a chassis designed for 15.2 V, even if the physical shape appears similar. Check the label on your existing pack and order only when it reads 15.2 V.

Questions about this item

Which Dell laptop models accept the GRT01 15.2V 64Wh battery?

The GRT01 fits Dell Latitude 5421, 5431, 5521, 5531, Precision 3561, 3571, 3470 and Alienware M17 R5 AMD series.

Can I keep my original 9JRV0 11.4V 97Wh battery and swap in the GRT01 when needed?

No, the 9JRV0 and GRT01 have different voltages and cell counts, so they are not interchangeable in the same laptop.

After installing the GRT01, how do I confirm it is charging correctly?

The laptop should show the battery charging to 100% without error; run a full charge and discharge cycle two or three times to calibrate the new cells.
