60Wh 6-cell Li-ion replacement for Dell Latitude

This 60Wh lithium-ion battery uses six cells at 11.1V to replace original Dell packs in Latitude E6420 E6520 E6530 E6430 E5420 E5520 and Inspiron 15R 17R models. It matches part numbers T54FJ M5Y0X 8858X and others listed. Buyers needing higher capacity or a different voltage will not find it here.

Simple swap with built-in safeguards

The pack fits the existing bay and locks with the laptop’s own latch, so no tools are required beyond a screwdriver for the bottom cover. Overcurrent, overcharge, overdischarge and temperature protection circuits are integrated. Misaligned connectors or a locked BIOS battery check are the most common install issues.

Limited by the 11.1V platform and 500-cycle design

The 11.1V output is fixed by the cell chemistry and cannot be changed for longer run-time. Rated at up to 500 recharge cycles, capacity will gradually decline with age and heat. Systems that demand a higher watt-hour rating or a different voltage rail are not supported.

Questions about this item

How can I verify the 60Wh 11.1V battery is working correctly after installing it in my Latitude E6420?

The system should detect the 6-cell pack, show 11.1V and 5200mAh capacity in BIOS or Dell Power Manager, and run without sudden shutdowns while the overcurrent, overcharge, overdischarge and temperature protections remain active.

What comes in the box with the PISKEKAT T54FJ battery and do I need any extra parts for my Inspiron 15R-5520?

The package contains the 60Wh Li-ion battery only; no tools, cables or adapters are included and none are required — the pack fits directly into the existing battery bay of the listed Dell models.

Which part number from the list matches a Precision M2800 that currently uses a 312-1310 battery?

The 312-1310 part number appears in the compatible P/N list, so this 60Wh 6-cell 11.1V unit is the correct replacement for that Precision M2800.
