NShi 1796/2017 laptop battery 7.57V 45Wh 5940mAh for Surface Pro 5 6

Ready replacement for Surface Pro 5 and 6

This lithium-ion battery is built for Microsoft Surface Pro 5th Generation 1796 series tablets and Surface Pro 6 models 1807, 1809 and 1796 from 2018. It matches the original 7.57V voltage and 45Wh or 5940mAh capacity. Grade A cells and integrated circuit protection reduce leakage risk and stabilise output. The black pack fits the 12.3-inch Core i5, i7 and m3 devices listed in the compatible part numbers.

Steady discharge across a work session

Under sustained load the cell chemistry delivers consistent voltage without the sharp drops seen in aged packs. The 45Wh rating supports extended typing, browsing and video playback on a single charge. Built-in protection circuits guard against over-current and short-circuit events during prolonged use. Capacity remains stable through repeated cycles thanks to the Grade A cell selection.

Cool operation with no moving parts

The solid-state lithium-ion design generates minimal heat during normal charging and discharging. No fan or pump is present, so acoustic output is zero. Power draw follows the tablet’s own management system, peaking only during rapid charge phases. The pack meets the original 7.57V specification without exceeding the thermal envelope of the 12.3-inch chassis.
