Replacement Battery for Surface Pro X 1876

This lithium-polymer battery replaces the G3HTA056H pack used in the Microsoft Surface Pro X 1876 SQ1 3.0GHz MQ03 tablet. It supplies 7.58V and 38.2Wh of capacity from four Grade A cells. The unit is brand new and intended for owners whose original cell no longer holds a useful charge.

Build Quality and Daily Use

Grade A cells reduce the chance of leakage and keep voltage output stable during normal workloads. An integrated protection circuit guards against over-charge, over-discharge and short-circuit events, helping the pack last longer. The black housing matches the original form factor so the tablet closes flush without gaps or loose edges.

Upgrade Context and Fit

This pack directly substitutes the factory battery in Surface Pro X 1876 and MQ03 models; it is not compatible with other Surface lines. The jump is worthwhile when the original battery drains quickly, swells or triggers a replacement warning. Buyers who need higher capacity than 38.2Wh or a different voltage should look elsewhere.

  • Grade A cells reduce leakage risk and extend usable life

Questions about this item

What voltage and capacity does the G3HTA056H battery deliver for the Surface Pro X 1876?

It supplies 7.58 V and 38.2 Wh (5039 mAh) using four Grade A lithium-ion cells with built-in circuit protection.

What physical space must be free inside the Surface Pro X 1876 to accept this battery?

The pack is a direct replacement for the original G3HTA056H module, so it fits the factory battery bay without adapters or chassis modification.

Which connector alignment step is most often missed when fitting the MQ03 battery?

Align the flex-cable keying notch with the motherboard socket before pressing; forcing it reversed bends pins and prevents the tablet from powering on.
