Compatible Microsoft Surface 3 1645 Replacement

This lithium polymer battery replaces the original G3HTA003H and G3HTA004H units in the Microsoft Surface 3 1645. It delivers a capacity of 7270mAh and 27.5Wh at 3.78V. The part is supplied new and tested to charge and discharge fully on a working laptop. It is intended for owners of that specific model who need a direct swap.

Polymer Cell Build and Connector Fit

The pack uses a polymer cell construction housed in the original form factor. A single connector mates with the motherboard header; correct alignment is required during installation. No fitting instructions are included, so users should follow a reliable guide or seek a technician. The package contains one battery only.

Thermals and Power Behaviour

Normal operation sees the cell run at typical lithium polymer temperatures for ultraportable devices. A new unit reaches its best performance after 2 or 3 complete charge and discharge cycles. Using a low quality charger can shorten service life. The battery draws power within the design limits of the Surface 3 1645 platform.
