It also fits the Siberia 800, Siberia 840, and 61298RX. When the original cell degrades and the headset can no longer hold charge through a session, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eH Wireless, Siberia 800, and Siberia 840 compatibility:\u003c\/strong\u003e\n    These models share the same compact cell housing, connector pinout, and BMS handshake protocol — all three run the same 3.7V rail and accept the 160240 form factor without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the SteelSeries base station charge cycle and confirmed the BMS completed the handshake, accepted a full charge, and reported accurate capacity to the headset firmware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge in the base station:\u003c\/strong\u003e\n    Seat the headset in the base station and let it complete one full charge cycle before use. DECT-based headsets log the new cell during this cycle — skipping it causes the talk-time indicator to misread the actual cell state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the H Wireless cuts out under combined audio and DECT radio draw\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe H Wireless runs both the audio codec and the DECT radio from the same cell simultaneously. Under peak load — loud audio transients plus active transmission — instantaneous current draw spikes sharply. If the cell's internal resistance has climbed through age or degradation, voltage sags below the BMS cutoff threshold and the headset drops. A fresh cell with lower internal resistance handles those spikes without triggering the protection circuit.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows full charge but headset shuts off after a few minutes\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell ships at storage voltage — typically around 3.6–3.8V — not full charge. The base station indicator can show a charge-complete state before the BMS has logged the cell's true capacity baseline. This is resolved by running one complete charge-to-drain cycle through the base station. After that first conditioning cycle, the headset's charge indicator and the actual cell state will track correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428141170778,"sku":"BWCS-SLS800SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428141203546,"sku":"BWCS-SLS800SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428141236314,"sku":"BWCS-SLS800SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SLS800SL-1.webp?v=1779934247","url":"https:\/\/batteryweb.com\/products\/steelseries-h-wireless-gaming-headset-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
