Direct Replacement Battery

The TOPKTEAM T0TRM TOTRM Y758W is a new 11.1V 4400mAh lithium-ion pack rated at 61WH. It matches the original Dell part numbers 0H76MY 7D1WJ Y758W 245RR for the XPS 15 9530 series and Precision M3800 notebooks. Builders restoring factory runtime will find the voltage and capacity identical to the OEM specification.

Black Lithium-Ion Housing

The black Li-ion casing fits the existing battery bay without adapters or cable modifications. Standard Dell latch points align so the pack secures with the same click as the original unit. No extra mounting hardware or wiring changes are required during the swap.

Ready-to-Install Cell Pack

The battery ships as a complete cell assembly with the factory connector already attached. No separate charger, calibration software or firmware utility is bundled. Install the pack, charge through the laptop AC adapter and the system recognises the capacity immediately. Not suited for users needing an external power bank or a higher-capacity extended-life option.

Questions about this item

Does the 11.1V lithium-ion chemistry limit charging to a specific Dell controller?

The 11.1V lithium-ion pack is built to match the original Dell charging circuit for the XPS 15 9530 and Precision M3800, so it charges normally through the laptop's own power management.

Will the 61WH black casing align with the 245RR and 0H76MY mounting points?

Yes, the replacement case follows the 245RR and 0H76MY screw-hole pattern and latch positions, fitting the XPS 15 9530 and Precision M3800 chassis without modification.

What is the correct first step when installing the Y758W battery?

Power off the notebook, disconnect the AC adapter, then remove the bottom cover screws before unplugging the old battery connector — skipping the AC disconnect risks a short circuit.
