Replacement battery for Surface Pro 1 and 2

This lithium-ion pack delivers 7.4 volts and 42 watt-hours of capacity, matching the original specification for Microsoft Surface Pro 1 model 1514 and Surface Pro 2 model 1601. It uses Grade A cells to reduce leakage risk and maintain stable output over repeated cycles. The unit ships new and includes a basic tool kit for installation.

Built-in protection and conditioning routine

Integrated circuit protection guards against overcharge, over-discharge and short circuits to extend usable life. The supplier advises a specific break-in process: discharge to five percent, charge to ninety-five percent and repeat three to four times before regular use. This routine helps the battery management system calibrate accurately from the start.

Capacity suited to daily tablet workloads

At 5676 milliampere-hours the pack supports typical web browsing, document editing and media playback on the 10.6-inch display for a full work session. Heavy multi-tasking or sustained high brightness will deplete the charge faster and require midday top-ups. Users needing all-day runtime without a charger should consider a higher-capacity alternative.

Questions about this item

How often should the 7.4V 42Wh lithium-ion cell be recalibrated after installation?

Discharge to 5 % then charge to 95 % and repeat the cycle three to four times during the first use period.

What is the first limit reached during continuous load on the 5676 mAh pack?

The built-in protection circuit will cut output if voltage drops too low or current exceeds safe thresholds.

Does the replacement battery generate noticeable heat or fan noise during all-day operation?

The pack itself has no moving parts; any warmth comes from the tablet’s own thermal management.
