Cameron Sino DS-CS-MIS135SL battery

The Cameron Sino DS-CS-MIS135SL is a 7.5V 5500mAh lithium-polymer replacement battery built for Microsoft Surface Book 13.5 inch devices. It matches part numbers G3HTA021H, G3HTA023H, G3HTA024H and G3HTA048H and fits Surface Book Gen1 and Gen2 13.5 inch models including 1703, 1704 and 1705. The pack measures 298.24 x 140.00 x 3.70 mm and comes in black.

Who this suits and who should look elsewhere

This battery suits owners of a 13.5 inch Surface Book Gen1 or Gen2 who need a direct replacement for the original pack. It is not for users with other Surface Book screen sizes, different Microsoft tablet lines, or laptops that use a different voltage or connector layout. Buyers who need a higher capacity than 5.5 Ah should consider other options.

Deciding specification

The single specification that decides fit is the 7.5V 5500mAh rating combined with the exact part-number match to G3HTA021H, G3HTA023H, G3HTA024H or G3HTA048H; if your device lists one of those numbers this battery will work, otherwise it will not.

Questions about this item

Will the 298.24 mm by 140.00 mm by 3.70 mm battery fit inside my 13.5 inch Surface Book?

Yes, the dimensions match the original G3HTA021H, G3HTA023H, G3HTA024H and G3HTA048H packs used in Surface Book 1 13.5 Inch and Surface Book 2 13.5 Inch models 1703, 1704 and 1705.

What is the step people often miss when installing this 7.5 V 5500 mAh Li-Polymer pack?

After placing the battery, you must reconnect the fragile ribbon cable and press the adhesive strips firmly so the pack sits flush before reassembling the chassis.

When will this 41.25 Wh replacement battery need to be swapped again?

Li-Polymer cells typically deliver several hundred full charge cycles; replace the pack once run-time falls below your needs.
