Replacement Battery for Surface Book 2 15

This KingSener G3HTA041H battery replaces the original pack in Microsoft Surface Book 2 15 inch devices. It delivers 11.36V and 62.2Wh capacity using Li-polymer cells. The unit matches the original dimensions for direct installation without modification. Buyers needing a different voltage or form factor should look elsewhere.

Thermal and Power Behaviour in Normal Use

The 5473mAh pack supplies stable voltage during typical office workloads without generating noticeable heat. Li-polymer chemistry maintains consistent output across the discharge curve. No active cooling is required because the battery sits inside the tablet section of the device. Users who keep the charger connected continuously may reduce long-term cell health.

Sustained Load Performance

Under continuous heavy use the battery discharges at a steady rate until the low-voltage threshold triggers system sleep. Full charge cycles repeated two or three times help the pack reach its rated 62.2Wh. Storage above 80 percent charge is recommended if the device is unused for a month or more. The pack is not designed for user disassembly or operation in hot environments.

Questions about this item

How do I install the G3HTA041H battery in my Surface Book 2 15"?

Power off the laptop, remove the bottom panel screws, disconnect the old battery connector, fit the new G3HTA041H unit, reconnect the cable, then replace the panel and screws.

What maintenance will the 62.2Wh Li-polymer battery need over its life?

Fully charge and discharge it two or three times at first, avoid leaving the adapter connected continuously, store above 80% charge if unused for a month, and keep it away from heat and humidity.

At what point does the 5473mAh capacity limit runtime during sustained use?

Runtime ends when the 62.2Wh charge is depleted; the battery delivers its rated capacity until voltage drops to the cutoff point, after which it must be recharged.
