Questions about this item
Will this 6-cell 11.1 V pack fit my Dell Inspiron 15 3543 without modification?
Yes, the battery is listed as a direct replacement for the Inspiron 15 3543 and matches the original 6-cell 11.1 V form factor.
What is the common mistake when installing this battery in a Dell Inspiron 17 3721?
Forgetting to slide the release latch fully before pulling the old pack out; the new battery clicks only when the latch is fully engaged.
When will the 4400 mAh capacity of this Dr. Battery unit need replacing?
The 1-year warranty covers defects; typical lithium-ion cells last 2–3 years before runtime falls below useful levels.
