SteelSeries Arctis Nova Pro Compatible Battery 3.7V 700mAh

SteelSeries Arctis Nova Pro — 3.7V Li-ion Replacement Battery (82-2-7136898)

This is a 3.7V, 700mAh Li-ion cell that replaces the original battery in the SteelSeries Arctis Nova Pro wireless headset (model 61527). It restores wireless audio functionality when the factory cell has degraded or stopped holding charge. Voltage and capacity match the OEM spec exactly.

• Arctis Nova Pro and 61527 compatibility: Both model references share the same 3.7V power rail, physical footprint (40.00 × 31.10 × 5.90mm), and BMS handshake protocol — the base station communicates charge state through the same connector on each variant.
• Bench tested on actual hardware: We ran this cell through the Arctis Nova Pro base station charge cycle and confirmed the BMS handshake completed correctly — the station accepted the pack, reported charge progress accurately, and released to active use without error flags.
• Base station initialisation on first install: Seat the headset in the base station and let it complete one full uninterrupted charge cycle before using it. The base station logs the new cell during this cycle — skipping it causes the talk-time indicator to read inaccurately until the handshake finalises.

Base station showing a charging error after fitting a new pack

The Arctis Nova Pro base station uses a BMS handshake to verify the connected cell before beginning a charge cycle. If the new battery arrives at storage voltage — typically around 3.6V — the base may flag an error rather than start charging. Remove the headset from the base, wait 10 seconds, then reseat it firmly. A clean reseat resets the handshake sequence and the base station will usually begin charging on the second attempt.

Headset cutting out mid-call even with a battery showing charge

The Arctis Nova Pro draws current simultaneously from the audio codec and the 2.4GHz wireless radio — combined draw peaks during active calls, not idle playback. If the cell voltage sags below the BMS cutoff threshold under that combined load, the headset powers off even when the indicator shows remaining charge. This is most common in the first few cycles before the cell reaches full capacity. Charge the headset fully and complete three to five full discharge-and-charge cycles — peak load voltage should stabilise above the 3.2V cutoff threshold after conditioning.
