43WH replacement for Dell Inspiron and Latitude

This 43WH lithium-polymer battery fits Dell Inspiron 14 5000 and 15 5000 series models including 5445, 5447, 5448, 5542, 5543, 5545, 5547 and 5548. It also supports Latitude 14 3450 and 15 3550 systems. The pack replaces part numbers such as TRHFF, P39F, P49G and 0PD19. Two screwdrivers are included for installation.

Thermals and power in daily use

The 11.1V three-cell design delivers up to 500 recharge cycles with built-in overcharge, overdischarge, over-temperature and short-circuit protection. Normal operation stays within standard thermal limits for ultrabook-class chassis. No active cooling is required and the pack adds no audible noise to the system.

Upgrading from a depleted original pack

This unit replaces a worn-out factory battery that no longer holds a useful charge. The jump is worth it when runtime has dropped below acceptable levels or the original pack shows swelling. It is not for buyers who need a higher-capacity pack than 43WH or who require a different voltage.

Questions about this item

How do I install the battery and which step is often missed?

Remove the base cover, disconnect the old pack, fit the new 3-cell 11.1V unit, reconnect the cable, then refit the cover. People often forget to reconnect the battery cable before screwing the cover back on.

What maintenance or replacement will this battery need later?

The Li-polymer pack is rated for up to 500 recharge cycles. After that capacity drops noticeably and a replacement will be required.

What limit appears first during sustained use?

The 43Wh capacity sets the runtime ceiling; under continuous load the pack will deplete before any thermal or cycle limit is reached.
