Replacement battery for Dell Inspiron models
This 4-cell lithium-ion unit replaces the original pack in Dell Inspiron 14, 15 and 17 series laptops including the 3421, 3521 and 5749 families. It delivers 14.8 volts and 2200 mAh for direct drop-in compatibility. Buyers who need a higher-capacity pack or a different voltage should look elsewhere.
2200 mAh capacity and 32 Wh energy rating
The pack supplies enough headroom for typical office tasks, web browsing and video playback on supported Inspiron chassis. Runtime will shrink under sustained heavy loads such as gaming or rendering, where the 4-cell design reaches its limit faster than larger 6-cell or 9-cell alternatives.
Lithium-ion chemistry
The built-in smart chip manages charging current, prevents short circuits and guards against overheat and overload conditions. It operates within the standard lithium-ion voltage window, so it cannot be used in systems that require a different cell chemistry or external battery interface.

Questions about this item
Will this 14.8 V, 4-cell battery fit alongside the original Dell AC adapter I already use?
Yes. The pack matches the factory 14.8 V output your adapter expects, so the existing charger works unchanged.
How can I confirm the 32 Wh pack is recognised after installation?
Open the Dell BIOS or Dell Power Manager; both display the detected capacity and cell count for immediate verification.
Does the box include fitting screws or only the 4-cell battery itself?
Only the battery is supplied; Dell chassis screws are reused during installation.
