Compatible Dell Inspiron models

This replacement battery fits Dell Inspiron 13, 14, 15 and 17 laptops across the 5000 and 7000 series. Supported models include 7573, 7378, 5567, 7579, 5767, 5379, 5579, 7375, 5584, 7569, 5368, 7368, 7278, 5770, 5482 and 5378. It replaces original part numbers WDX0R, YRDD6, P69G and FW8KR.

Sustained runtime and cycle life

The lithium-ion pack is rated at 42Wh, 3500mAh and 11.4V using grade A cells and a smart control chip. The manufacturer rates it for over 1000 charge cycles, so capacity holds up through daily charge and discharge routines. Overheat, short-circuit and overload protections maintain stable output during extended sessions.

Upgrade from worn original batteries

This unit replaces a depleted or failing factory battery that no longer holds a useful charge. The jump is worth it when the original pack delivers only a fraction of its rated runtime or triggers sudden shutdowns. Buyers needing higher capacity than 42Wh or a different voltage should look elsewhere.

Questions about this item

Does the 11.4 V 42 Wh battery generate noticeable heat or noise during all-day use?

The replacement battery uses A-grade Li-ion cells and a smart control chip with overheat, short-circuit and overload protections, so it runs silently and stays cool under normal daily loads.

What must I already own for this 42 Wh pack to work in my Dell?

You need a compatible Dell Inspiron 13, 14, 15 or 17 from the 5000 or 7000 series such as the 5379, 5579, 7378, 7573 or other listed models; the battery replaces the original WDX0R, YRDD6, P69G or FW8KR unit.

Will this 11.4 V battery function correctly alongside the original charger and motherboard in an older Inspiron 7000?

Yes, the pack matches the factory 11.4 V / 42 Wh specification and includes the same smart control chip, so it communicates properly with the existing charging circuit and power management.
