Replacement for Surface Pro 3 1645

This KingSener G3HTA007H lithium-ion battery replaces the original power pack in Microsoft Surface Pro 3 1645 series tablets. It delivers 27.5WH of energy at 3.78V using cells produced in China under a 100-percent-new build standard. The physical footprint matches the factory unit so installation requires no modification.

Steady discharge for daily workloads

High-quality cells and a protected circuit board maintain stable voltage through a full work session instead of sagging after a brief burst. The maker states the real full-charge capacity meets or exceeds the 7270mAh design rating. A break-in routine of three low-current charge-discharge cycles helps the pack reach its rated endurance.

Voltage match decides fit

The single specification that determines compatibility is the 3.78V nominal output; a pack with a different voltage will not operate the tablet safely. Buyers who need a higher-capacity cell or a different voltage platform cannot use this model. Confirm the original battery part number and connector layout before ordering.

Questions about this item

Does the 3.78 V lithium-ion cell generate noticeable heat or noise during continuous daily use?

The battery is a passive component with no moving parts, so it produces no audible noise and only minimal warmth during normal charge and discharge cycles.

What must I already own to install this G3HTA007H replacement in my Surface Pro 3 1645?

You need a compatible Microsoft Surface Pro 3 1645 tablet and basic tools to open the case, as the battery fits the original compartment without adapters.

Will this 27.5 Wh pack work reliably alongside the original charging circuitry in an older Surface Pro 3?

Yes, the voltage and connector match the factory design, so the existing charge controller manages the cell correctly without modification.
