Direct replacement for Surface Go 2

This GreenTechLLC battery is a new two-cell lithium-ion pack built to fit Microsoft Surface Go 2 models 1901, 1926 and 1927. It delivers 7.66 volts and 3500 milliampere-hours for 26.81 watt-hours of capacity. The black cell measures 6.9 by 3 by 0.2 inches and weighs 0.5 pounds. It is intended for owners who need a like-for-like power source for those specific tablets.

Upgrade from a depleted OEM cell

The unit replaces OEM part numbers DYNU01 and G16TA047H, so it suits anyone whose original battery no longer holds a useful charge. Swapping is worthwhile when runtime has dropped noticeably or the tablet shuts down under load. Each pack is tested for correct voltage, circuit protection, stable current and low self-discharge before it leaves the supplier. Buyers who need a higher-capacity design or a different form factor will not be served by this model.

Capacity and practical headroom

At 26.81 watt-hours the battery restores the factory energy budget for everyday tasks such as web browsing, document editing and media playback. Heavy workloads that draw sustained peak power will exhaust the pack more quickly, and the two-cell layout cannot be expanded internally. Users who require all-day operation without recharging should plan for an external power bank instead.

Questions about this item

Will the 6.9 x 3 x 0.2 inch dimensions fit my Surface Go 2 model 1901?

Yes, the battery is built to the exact 6.9 x 3 x 0.2 inch form factor used in the Surface Go 2 models 1901, 1926 and 1927, so it seats correctly in the chassis.

What is the most common mistake when installing the DYNU01 G16TA047H battery?

Forgetting to disconnect the old pack's connector before prying it out; the ribbon cable is fragile and tears if pulled while still attached.

How often will the 2-cell 3500mAh pack need replacing under daily use?

A 2-cell lithium-ion pack of this capacity typically lasts two to three years of daily charging before runtime drops noticeably.
