Direct replacement for MSI Modern 15 A10RB

This KingSener BTY-M491 lithium-polymer battery is built to fit the MSI Modern 15 A10RB series, including the 041TW, 033CN, 034CN and A10M-035CN models. It restores the original 52.4 Wh capacity at 11.4 V so the laptop runs on battery power exactly as designed.

Simple swap with no soldering

The pack matches the factory 3ICP6/71/74 form factor and connects to the existing motherboard header. Installation only requires removing the bottom case screws and disconnecting the old pack. The main risk is damaging the fragile ribbon cable or forgetting to reconnect the battery connector before reassembly.

52.4 Wh for typical office use

A fresh cell delivers roughly 4600 mAh, enough for several hours of document editing, web browsing or video playback. Heavy workloads such as sustained compiles or gaming will drain the charge faster, and the pack will not support extended off-grid sessions without a charger nearby.
