Replacement Battery for Dell Inspiron 11 13 15
This 11.1 V lithium polymer pack delivers 3800 mAh and 43 Wh of capacity. It is built as a direct replacement for the original Dell part numbers 04K8YH 4K8YH 92NCT CK5KY GK5KY RHN1C 451-BBKK. The unit is new and includes a smart control chip that manages charging and discharge cycles. It fits Dell Inspiron 11 13 and 15 models including 3147 3148 3152 3157 3158 7347 7348 7352 7353 7558.
Lithium Polymer Voltage and Capacity Limits
The battery operates at a fixed 11.1 V so it cannot be used in laptops that require a different voltage. Its 3800 mAh capacity sets the total energy available per charge and cannot be expanded without a physically larger pack. The integrated protection circuit guards against short circuit overheat and overload but does not increase the cell chemistry limits. Runtime will vary with system load screen brightness and background tasks.
Upgrading from Worn or Failed Original Packs
This unit replaces an original battery that no longer holds charge or that has swollen. The jump is worth it when the laptop shuts down unexpectedly or runs only a few minutes on battery. It is not for users who need a higher capacity than 43 Wh or a different form factor. Buyers should verify the exact model number and original part number before ordering.

Questions about this item
Which Dell models does the MPL05280P-09 battery fit?
It replaces the original Dell part numbers 04K8YH, 451-BBKK, 4K8YH, 92NCT, CK5KY, GK5KY and RHN1C for Inspiron 11 3147, 3148, 3152, 3157, 3158, 13 7347, 7348, 7352, 7353 and 15 7558.
What does the 43Wh rating mean for daily use?
The 43 watt-hour capacity stores the same energy as the original Dell battery, giving comparable run time between charges on supported Inspiron 11, 13 and 15 models.
What interface does the battery use and what does it limit?
It connects through the laptop's proprietary battery connector, so the 11.1V output and 3800mAh capacity are fixed by that interface and cannot be changed.
