Dr. Battery MPL03346P-25 Replacement

This 15.4V lithium-polymer battery replaces the original pack in compatible Asus ROG Zephyrus and ProArt StudioBook models. It is built for owners who need a new power source that matches the factory voltage and cell chemistry. The unit arrives new and includes a one-year warranty from the manufacturer.

76Wh capacity for daily mobility

The 4940mAh rating delivers 76Wh of energy, supporting typical work sessions and light gaming away from a wall outlet. Runtime scales with screen brightness, CPU load and GPU activity; heavy 3D workloads will drain the pack faster than office tasks. Users who regularly run sustained high-performance profiles should plan for mid-day recharging.

Direct fit for listed Asus chassis

The battery slots into the existing bay without adapter cables or firmware updates. Its smart control chip manages charging current, short-circuit protection and thermal limits automatically. Buyers who need higher watt-hour ratings or a different voltage must look elsewhere, as this model is fixed at 15.4V and 76Wh.

Questions about this item

Will this 15.4V 4940mAh replacement fit alongside the original cooling system in my GU502LW?

The battery matches the OEM form factor for the listed Asus models, so it sits in the same bay without interfering with the existing cooling assembly.

How can I confirm the smart control chip is balancing the lithium-polymer cells correctly after installation?

The battery should charge to 100 % in the OS, report 15.4 V, and hold runtime consistent with 76 Wh; any deviation suggests a calibration cycle is needed.

Does the package include the 41N1837 battery and the 0B200-03380100 screw kit, or must I order tools separately?

Only the battery is supplied; mounting screws and any opening tools are not included and must be sourced separately.
