Compatible Replacement Battery

The Kastar LI-42B is a lithium-ion battery built to replace the original cell in SteelSeries Arctis Nova Pro Wireless headsets, including the Xbox and PlayStation editions. It delivers 3.7V and 1400mAh capacity for extended wireless sessions.

Upgrade From Worn Original Cells

Swap this in when the factory pack no longer holds a charge or runtime has dropped noticeably. The 5.18 Wh rating restores like-new endurance, and the built-in protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating.

Check Headset Model Before Ordering

Verify you own one of the three listed Arctis Nova Pro Wireless variants, as this pack fits only those models. The single-battery pack contains one LI-42B cell; ensure your headset uses a user-replaceable battery compartment before purchase.

Questions about this item

What are the voltage and capacity figures I should match when fitting this LI-42B pack?

The cell is rated at 3.7 V and 1400 mAh, giving 5.18 Wh; match those numbers exactly when selecting a replacement.

How do I install the battery in my Arctis Nova Pro Wireless headset, and what step is often missed?

Slide the pack into the left ear-cup compartment until the connector clicks, then close the cover; the step people skip is pressing the connector firmly so the pins seat fully.

When will this LI-42B need replacing and what safety standards back its cycle life?

Replace the pack when run-time falls sharply; the cells meet UL 1642 and CE standards and include over-charge, over-discharge, over-voltage, over-current and over-heating protection.
