Replacement for Dell Inspiron 14, 15 and 17 models
This Dr. Battery MPL05283P-20 is a new 4-cell lithium-ion pack rated at 14.8V and 2200mAh. It matches the original specifications for numerous Inspiron 14, 15 and 17 series laptops including 3421, 3437, 3442, 3521, 3531, 3541, 3542, 3543, 3721 and 3737 models. The black casing fits the standard battery bay on these machines.
Fits the original battery bay without adapters
The pack uses the same form factor and connector as the Dell batteries it replaces, so installation only requires removing the old unit and slotting this one in. No extra cabling, mounting brackets or BIOS updates are needed. The 32Wh capacity restores the runtime the laptop had when it left the factory.
Built-in protection chip manages charging safety
An integrated smart control chip handles overcharge, short-circuit, overheat and overload safeguards automatically. It also optimises charge speed and reduces idle power draw, which helps the cells last longer through daily cycles. A one-year manufacturer warranty covers defects in materials or workmanship.

Questions about this item
How long will the 2200 mAh capacity last before the battery needs recharging under a steady workload?
The 4-cell lithium-ion pack stores 32 Wh at 14.8 V, so runtime depends entirely on the laptop's power draw; a typical 14–15 inch Dell Inspiron will run for several hours on a full charge.
Does the battery run hot or make noise when the laptop is used all day?
The pack has no moving parts and produces no audible noise; normal warmth occurs during charge or heavy discharge, but the built-in protection chip guards against overheating.
Which original Dell battery part numbers must match for this replacement to fit and work?
Compatible part numbers include MR90Y, N121Y, PVJ7J, T1G4M, V1YJ7, V8VNT, VR7HM, W6XNM, X29KD, XCMRD, XRDW2, YGMTN and 0MF69.
