Replacement battery for MSI Modern 15

This 11.4V lithium-ion pack supplies 52.4Wh of capacity and matches part number 3ICP6/71/74. It is built for owners of the Modern 15 A10RB and A10RB-041TW models who need a direct replacement. The cell chemistry is rechargeable and certified to CE, FCC and RoHS standards.

Single-voltage 11.4V constraint

The pack delivers only its rated 11.4 volts, so it cannot serve devices that require a different cell voltage or a higher watt-hour rating. The fixed output also means it will not function as a multi-voltage power source for other laptop families or external peripherals.

52.4Wh capacity for typical mobile workloads

At 52.4Wh the battery supports several hours of office applications, web browsing and video playback on the compatible Modern 15 chassis. Runtime drops under sustained heavy loads such as rendering or gaming, and the pack cannot extend beyond its rated watt-hours without a larger-capacity alternative.
