43Wh 11.1V replacement for Inspiron and Latitude 15

This lithium-ion battery delivers 43Wh at 11.1V and fits Dell Inspiron 15 models 5445 5545 5447 5547 5448 5548 plus Latitude 15 3550 series. It replaces part numbers 31CP6 60 80 1V2F6 01V2F 1WWHW DL011307-PRR13G01 0PD19. The pack ships new in black with a 12-month warranty.

Sustained output from a 43Wh lithium-ion cell

The 43Wh capacity supports typical office workloads across a full workday without the voltage sag seen in aged packs. Lithium-ion chemistry maintains stable 11.1V delivery under continuous load rather than dropping off after a short burst. The 12-month warranty covers capacity retention during regular daily cycling.

Upgrades worn 3-cell packs in listed Dell chassis

This unit replaces an exhausted original battery in the exact Inspiron and Latitude models named above. The jump is worth it when runtime has fallen below two hours or the system throttles on battery power. It does not fit laptops outside the 5445 5545 5447 5547 5448 5548 3550 series or machines requiring a different voltage or connector.

Questions about this item

How much heat does the 11.1V 43Wh lithium-ion cell generate during a full day of use?

Lithium-ion cells at 11.1V and 43Wh run cool under normal loads; the pack produces only modest warmth that the laptop’s existing cooling handles without extra fan noise.

Which Dell models must I already own for the 31CP6/60/80 pack to fit and charge?

It fits Inspiron 15 5445, 5447, 5448, 5545, 5547, 5548 and Latitude 15 3550 series; the part replaces Dell numbers 1V2F6, 01V2F, 1WWHW, DL011307-PRR13G01 and 0PD19.

Will the 43Wh replacement work alongside the original 13-inch charger and BIOS on a Latitude 3550?

Yes — the 11.1V 43Wh pack matches the factory voltage and communicates with the Latitude 3550 BIOS, so the original 13-inch charger and power management behave identically.
