Replacement Battery for Dell Inspiron Laptops
This new Dr. Battery unit replaces the original power cell in a wide range of Dell Inspiron 14, 15 and 17 inch models. It delivers 11.1 volts and 4400 mAh capacity from six lithium-ion cells. The pack is built for owners who need a direct-fit replacement for part numbers such as V8VNT, XCMRD or YGMTN.
Simple Swap with Built-In Protection
The battery slides into the standard compartment without tools or soldering. A smart control chip manages charging current, provides short-circuit, overheat and overload safeguards, and helps extend discharge time. The most common issue is ordering the wrong variant, so verify the exact model number printed on your old battery before fitting.
Check Model, Voltage and Part Number First
Confirm that your laptop appears in the supported list covering Inspiron 3421, 3437, 3442, 3443, 3521, 3531, 3541, 3542, 3543, 3721, 5421, 5521, 5537, 5721, 5737 and 5748. Match the 11.1 V output and compare the original Dell part numbers such as 0MF69, 24DRM, 312-1387, 312-1390, 312-1392, 312-1433 or 451-12107. Buyers whose machines fall outside this range or require a different voltage cannot use this pack.
