Dr. Battery MPL05351P-15 laptop battery 3947mAh 60Wh 15.2V

Dr. Battery MPL05351P-15 replacement

This Dr. Battery MPL05351P-15 is a new lithium-polymer laptop battery rated at 3947 mAh and 60 Wh with a nominal voltage of 15.2 V. It is built as a direct replacement for several Dell G7 15 and 17 models including the 7590 and 7790 series. The black pack uses a smart control chip that manages charging and discharging while providing short-circuit, overheat and overload protection.

Fits Dell G7 15 and 17 chassis

The battery matches the form factor and connector layout of the original Dell ALW15M and ALW15M-R series packs listed in the compatibility table. No additional cabling or adapter is required; the unit slots into the existing battery bay and connects to the motherboard header. Installing this pack restores mobile operation without occupying a drive bay or USB port, leaving internal expansion slots free for storage or wireless upgrades.

Sustained discharge at 15.2 V

Under continuous load the lithium-polymer cells deliver a steady 15.2 V output while the onboard protection circuitry regulates current to prevent thermal throttling. The 60 Wh capacity supports extended work sessions away from mains power, and the smart chip optimises charge cycles to reduce long-term capacity fade. The pack is designed for daily cycling rather than occasional emergency use.
