Replacement battery for MSI Modern and PS42 series

This Cameron Sino DS-CS-MSG420NB lithium-polymer pack is built for MSI Modern 14 and PS42 models including the A10RB, 8M, 8RA, 8RC and Mechrevo S1 variants. It replaces the original BTY-M48 and 4ICP5/41/119 cells in a black finish. The 15.2 V 3250 mAh rating delivers 49.40 Wh of energy for daily mobile work.

Steady output through a full workday

The 3.25 Ah cell maintains voltage evenly across the discharge curve so the laptop runs at consistent clocks without sudden throttling. Li-Polymer chemistry resists swelling over repeated cycles and the 49.40 Wh capacity supports typical office loads for a full day away from a socket.

Direct fit with no adapter required

The pack measures 286.60 x 92.40 x 5.75 mm and slots into the battery bay using the original screw points and connector. Installers should disconnect the mains adapter before fitting and calibrate with one full charge-discharge cycle. Not suited for buyers who need a higher-capacity pack or a different voltage for other laptop families.

Questions about this item

How warm does the DS-CS-MSG420NB get during a full day of use?

The 15.2 V 3250 mAh Li-Polymer pack runs at normal laptop-battery temperatures; no active cooling is needed and the slim 5.75 mm profile fits the original bay without extra heat buildup.

Does the battery ship with the screws or tools needed to fit it into an MSI Modern 14?

Only the battery itself is supplied; you reuse the existing screws and any standard Phillips driver you already have for the bottom case.

Will this 49.40 Wh pack work in an older MSI PS42 8RC that originally used a BTY-M48?

Yes — it replaces the BTY-M48 and matches the 15.2 V 3250 mAh spec, so the PS42 8RC charges and reports capacity normally.
