Microsoft Surface Book 2 G3HTA049H Keyboard Base Battery Review
Microsoft Surface Book 2 G3HTA049H (also G3HTA050H) keyboard base battery, an 11.36V 57.3Wh (5042mAh) pack for the Surface Book 2 13.5-inch base model 1835 and Surface Book 3 13.5-inch bases 1907 and 1909.
This is the larger of the Surface Book 2's two batteries, in the keyboard base. iFixit notes it does not fit the Surface Book 3 13.5-inch base model 1900. The screen half has its own 18Wh G3HTA044H battery.
What to check before you buy
Check the base model number printed under the hinge: 1835 (Surface Book 2 13.5) or 1907/1909 (Surface Book 3 13.5) take this pack. Base model 1900 does not.
