Direct replacement for Prestige 14

The KingSener BTY-M49 is a new lithium-polymer battery built to replace the original pack in MSI Prestige 14 models including the A10SC-009, A10SC-057RU, A10RB-015CN and i7-10710U variants. It matches the 11.4V operating voltage and 52.4WH capacity of the factory unit. The pack carries part number BTY-M49 3ICP6/71/74 925QA045H for exact identification.

Voltage and capacity limits

The battery delivers a fixed 11.4V output, so it only works in laptops designed for that nominal voltage; systems expecting a different voltage will not recognise the pack. Its 52.4WH rating sets the total energy available per charge, defining the maximum runtime the notebook can achieve. No higher-capacity version is offered in this form factor.

Typical workloads and runtime ceiling

A 52.4WH pack comfortably powers the Prestige 14 through office applications, web browsing and video playback for a full workday under normal brightness settings. Heavy multi-core compilation or sustained GPU loads will draw the reserve down faster, reducing usable time to roughly half that span. Users needing multiple days between charges should consider an external power bank instead.

Questions about this item

Does the 52.4 Wh capacity match the original battery for my Prestige 14 A10SC?

The replacement is rated at 52.4 Wh and 11.4 V, matching the factory specification for the Prestige 14 A10SC series.

What runtime can I expect from the 52.4 Wh rating in daily use?

At 52.4 Wh the pack stores the same energy as the original, so typical mixed workloads on a Prestige 14 i7-10710U deliver comparable battery life.

Will the BTY-M49 connector fit the MS-14C1 and MS-14D1 chassis?

The battery uses the exact BTY-M49 form factor and connector, so it seats correctly in MS-14C1, MS-14D1 and all listed Prestige 14 models.
