Replacement battery for MSI and Medion notebooks

This 11.1 V lithium-ion pack delivers 6800 mAh and 75 Wh of capacity. It replaces part numbers BTY-S14 and BTY-S15 in a wide range of MSI models including GE70, GE60, FX720, GE620, GE620DX, CX70, FX700 and the CR, CX and FR series. It also fits Medion Akoya Mini E1311, E1312, E1315 and MD97125, MD97127, MD9769 units. Builders needing a different form factor or voltage must look elsewhere.

Cells sourced from Korea and Japan for stable output

The lithium-ion chemistry provides consistent voltage across the discharge curve without memory effect. Internal resistance stays low during typical office and media workloads, so the pack runs cool and does not add audible fan activity. Power draw matches the original specification, keeping the laptop’s existing power management profiles intact.

Sustained discharge holds rated capacity over long

Under continuous load the cells maintain the declared 75 Wh without premature voltage sag. The pack is rated as a 100 % brand-new replacement and carries a two-year warranty against defects. Users who require hot-swap capability or a higher-wattage extended pack will not find those features here.

Questions about this item

How do I install the BTY-S14 battery in my MSI GE70 and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the old pack, insert the BTY-S14 until the latch clicks, then charge it fully before first use to calibrate the fuel gauge.

What maintenance will the BTY-S14 lithium-ion cells need over time?

No scheduled maintenance is required; avoid deep discharges, store around 50 % charge if unused for weeks, and replace the pack when runtime drops below your needs.

At what point does the 75 Wh capacity limit appear during sustained loads?

The 75 Wh rating sets the total energy available; under continuous high draw the voltage will sag to the cutoff threshold sooner, ending the session.
