Replacement battery for Dell Inspiron laptops
This four-cell lithium-ion unit replaces original batteries in Dell Inspiron 14, 15 and 17 models including the 3421, 3521 and 5721 series. It supplies 14.8 volts and 2200 milliampere-hours for mobile professionals who need a fresh power source.
32 watt-hour capacity and typical runtime
The 32 Wh pack delivers several hours of light office work or web browsing on a 15-inch system. Heavier loads such as video playback or sustained CPU tasks will drain the cells more quickly, so users running demanding applications should keep the charger nearby.
Built-in protection chip and one-year warranty
An integrated smart control chip manages charging current, prevents short circuits and guards against overheating or overload conditions. The manufacturer backs the battery with a one-year warranty and provides installation guidance through its website and video channel.

Questions about this item
Will this 14.8V 2200 mAh battery fit my Dell Inspiron 3521 alongside the original AC adapter?
Yes, the battery is listed as compatible with the Inspiron 3521 and other models in the same series, and it operates at the same 14.8 V as the original packs.
How can I confirm the 4-cell lithium-ion pack is working correctly after installation?
The built-in smart control chip manages charging and protections; the OS battery meter should show normal charge and discharge behaviour through a full cycle.
What comes in the box and do I need to buy any cables or tools separately?
Only the replacement battery is supplied; no screwdrivers, cables or additional adapters are included.
