Direct replacement for HP Spectre 13

This lithium-ion battery replaces the original SO04XL and HSTNN-IB7J packs in compatible Spectre 13 models. It supplies 7.7V and 38Wh of capacity for owners who need a new power source. Buyers with other HP series or non-listed Spectre variants cannot use this unit.

Thermal and power behaviour

The pack delivers its rated 4950mAh at the specified voltage without additional cooling hardware. Normal discharge generates only the heat typical of internal lithium-ion cells. No fan or active thermal management is included or required.

First-use conditioning routine

The manufacturer advises discharging to five percent then charging to ninety-five percent for three to four cycles before regular service. This process calibrates the fuel gauge and helps reach the rated 500 recharge cycles. No software or driver installation is involved.

Questions about this item

How do I install the NShi SO04XL battery in my HP Spectre 13 and what step is often missed?

Power off the laptop, remove the bottom case screws, disconnect the old battery cable, fit the new 7.7V 38Wh pack, reconnect the cable, replace the case, then discharge to 5% and charge to 95% for three to four cycles — skipping the conditioning cycles is the common error.

What maintenance will this 4950mAh lithium-ion battery need later?

The cell is rated for up to 500 recharge cycles; after that capacity drops noticeably, so plan a replacement once run-time becomes too short for daily use.

What limit appears first during sustained heavy loads on this 7.7V pack?

Voltage sag under high current draw triggers the laptop’s power throttling before the 38Wh capacity is fully used, reducing performance until the load eases.
