Direct replacement for Dell 2013-2018 laptops

This 40Wh lithium-ion battery fits Dell Inspiron 14, 15 and 17 models plus Latitude 3440, 3540 and Vostro 2421, 2521 series released between 2013 and 2018. It delivers 2700mAh at 14.8V across four cells and carries CE, UL and FCC safety certifications with built-in circuit protection. Buyers needing a higher-capacity pack or a different voltage will not be served by this unit.

Low heat and silent operation in daily use

The pack runs cool and makes no audible noise during typical office tasks, web browsing or video playback thanks to its low internal resistance and Class A cells. Integrated protection circuits guard against over-charge, over-discharge and short-circuit conditions while keeping power draw steady. Users who require active cooling or fan-assisted thermal management will not find those features here.

Consistent output through extended sessions

Rated for up to 500 recharge cycles, the battery maintains stable voltage during long work periods without the sharp drops seen in aged or lower-grade cells. Fast-charge support reduces downtime between sessions and the four-cell layout balances load evenly across the pack. Anyone expecting runtime beyond the 40Wh rating or unlimited cycle life should look elsewhere.

Questions about this item

How do I install the P28F battery and what step do people often miss?

Power off the laptop, disconnect the AC adapter, slide the release latch, remove the old pack, insert the new 14.8V unit until it clicks, then charge to 100% before first use — skipping that full initial charge is the common mistake.

What maintenance or replacement will the 4-cell 2700mAh pack need later?

The lithium-ion cells are rated for up to 500 recharge cycles; after that capacity drops noticeably and the pack should be replaced.

What limit appears first during sustained use of this 40Wh battery?

The 40Wh capacity sets the runtime ceiling; under continuous load the pack will deplete before any thermal or circuit-protection limit is reached.
