Replacement battery for Dell Inspiron models

This 4-cell lithium-ion unit delivers 14.8V and 2200mAh capacity, matching the original specifications for a wide range of Dell Inspiron 14, 15 and 17 inch laptops. It is built for owners of compatible Inspiron 3421, 3437, 3442, 3521, 3531, 3541, 3542, 3543, 3721, 3737, 5748 and related R-series models who need a direct replacement. The pack restores mobile runtime without requiring hardware modifications. It suits users replacing a worn or failed original battery.

Check your original battery part number and voltage

Before ordering, locate the part number printed on your existing battery — common codes include MR90Y, N121Y, PVJ7J, T1G4M, V1YJ7, V8VNT, VR7HM, W6XNM, X29KD, XCMRD, XRDW2, YGMTN, 0MF69, 24DRM or 312-1387. Confirm the original battery is rated at 14.8V and uses a 4-cell lithium-ion layout. Verify the physical connector and shape match the unit shown in product images. This step prevents fitment issues across the listed Inspiron families.

Built-in smart chip manages charging and safety

The integrated control chip regulates the charge cycle for quicker replenishment and lower power draw during use. It also provides short-circuit, overheat and overload protection to guard both the battery and the laptop. No extra software, drivers or cables are bundled; the battery is a standalone hardware component. The one-year manufacturer warranty covers defects in materials and workmanship under normal use.

How do I know if the 4-cell 14.8V 2200mAh version matches my original Dell battery?

Compare the part numbers on your old battery — MR90Y, N121Y, PVJ7J, T1G4M, V1YJ7, V8VNT, VR7HM, W6XNM, X29KD, XCMRD, XRDW2, YGMTN, 0MF69, 24DRM or 312-1387 — and confirm your laptop appears in the compatibility list.

What runtime can I expect from the 32Wh rating on a Dell Inspiron 15 3542?

The 32Wh capacity delivers a direct replacement for the original 4-cell pack; actual runtime depends on screen brightness, workload and power settings in the laptop.
