Dr. Battery MPL05240P-21 6-cell replacement
This new lithium-ion battery replaces the original pack in listed Dell Inspiron models. It delivers 10.8 volts and 4400 mAh capacity for portable power. The six-cell design fits the standard battery bay on compatible 13-inch to 17-inch chassis. Buyers who need a higher-capacity 9-cell pack or a different voltage cannot use this unit.
Practical limits of 10.8 V lithium-ion chemistry
Capacity degrades with each charge cycle and calendar age. Run-time depends on the laptop's power draw, screen brightness and active workloads. The built-in smart chip manages charging current and protects against short circuit, overheat and overload conditions. It does not increase the physical energy density beyond the 48 Wh rating.
Straightforward bay swap with verification steps
Power off the laptop and disconnect the AC adapter before removing the old pack. Align the replacement with the bay rails and press until the latch clicks. Confirm the original part number matches 312-0240, 312-1180 or other listed codes. A mismatched voltage or connector will prevent the laptop from recognising the battery.
