Dr. Battery 6-cell 11.1V replacement for Dell

This Dr. Battery MPL05225P-20 is a new 6-cell lithium-ion unit rated at 11.1V and 4400mAh (49Wh). It replaces original Dell part numbers such as 312-0701, 312-0702, C313K and KM887. The black pack fits Dell Studio 15, 15 Special Edition, 1535, 1536, 1537, 1555, 1557 and 1558 models. Buyers who need a different voltage or a higher capacity will not be served by this unit.

Simple slide-in install; verify part number first

Installation is a straightforward slide-in swap once the laptop is powered off and unplugged. The built-in smart control chip handles charging logic and protects against short circuit, overheat and overload. What usually goes wrong is ordering without matching the original battery part number or the laptop model suffix, leading to a physically incompatible or electrically mismatched pack.

Check your original battery label and laptop model

Before ordering, confirm the original battery carries one of the listed part numbers such as 312-0701, D293K, G275K or KM904. Verify the laptop model exactly matches the supported Studio 15 series including 1535, 1536, 1537, 1555, 1557 or 1558. Ensure the original battery voltage reads 11.1V; a different voltage means this pack will not work.

Questions about this item

After installing the MPL05225P-20, how do I confirm the 11.1V 49Wh battery is recognised and charging correctly?

The laptop BIOS should show 11.1 V and roughly 4 400 mAh capacity; the OS battery meter will then report charging progress and estimated runtime normally.

What comes with the Dr. Battery MPL05225P-20 and is anything else required for installation?

Only the 6-cell lithium-ion battery is supplied; no tools or cables are included, and the original Dell latch secures it in the bay.

My original Dell battery is marked 312-0701 — does the MPL05225P-20 replace it directly?

Yes, the MPL05225P-20 lists 312-0701 among its compatible part numbers and matches the 11.1 V 4400 mAh specification.
