Questions about this item

My Dell Latitude E6430 still uses the original AC adapter — will the T54FJ battery charge properly with that charger?

Yes. The 11.1 V 57 Wh lithium-ion pack is a direct replacement for Dell part numbers such as 04NW9, X57F1 and 312-1324, so the existing adapter charges it normally.

I plan to keep my older Inspiron 15R 5520 alongside the new battery — does the T54FJ fit that model without modification?

The battery is listed as compatible with Inspiron 15R 5520 and 5525, matching the same 6-cell 11.1 V form factor used in those chassis.

After installing the T54FJ in my Latitude E6440, how can I confirm it is delivering the rated 57 Wh capacity?

Run a full charge cycle in the BIOS battery health check or Dell Power Manager; a healthy new pack should report design capacity near 57 Wh and reach 100 % charge.
