It matches the OEM part number 1ICP10\/40\/46-2 and fits the original battery bay without modification. Capacity figures come from the product specification, not estimated values.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNeo3 and Neo3-1 compatibility:\u003c\/strong\u003e\n    Both headset variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol — 136.40 × 40.60 × 10.50mm cell with a 3.85V nominal rail. Swapping between these two models is not possible with a different cell geometry, which is why part number verification matters before ordering.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Neo3-1 unit and monitored the BMS communication line. The protection circuit engaged correctly at both the low-voltage cutoff and the charge-termination threshold, with no false trip events during load transitions from display wake to active rendering.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-session charging on VR hardware:\u003c\/strong\u003e\n    The Neo3's inside-out tracking processors draw from the same cell as the display and SoC — always charge to 100% before a long session. Tracking algorithms require a stable voltage floor; partial charges that leave the cell at 60–70% increase the risk of voltage sag during compute-heavy scenes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTracking drift events when battery drops below 20%\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Neo3's six-DOF tracking cameras and the SLAM processor pull current continuously. As the cell ages and internal resistance climbs, voltage sag under combined tracking-plus-render load crosses the processor's minimum input threshold earlier in the discharge curve — sometimes as high as 25% indicated charge. This manifests as sudden positional jumps or brief freezes in the headset view, which most users attribute to software rather than power. If drift events cluster in the final third of a charge, the cell's usable capacity has degraded past the point where the SoC voltage estimation stays accurate. Replacing the battery resets that voltage curve to factory spec.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset shuts down without warning mid-session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAn unannounced shutdown on the Neo3 is typically a hard BMS cutoff, not a software crash. The combined draw from the Snapdragon XR2 SoC, dual displays, Wi-Fi 6 radio, and inside-out cameras can spike current demand during scene transitions. If the cell's internal resistance is high enough, voltage briefly drops below the BMS trip point — around 3.0V per cell — and the protection circuit disconnects the load instantly with no OS-level shutdown sequence. The device will usually power back on immediately because resting voltage recovers above the cutoff once load is removed. Check whether this happens consistently during graphically intensive content; if it does, replace the cell and verify open-circuit voltage reads at or above 3.85V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428091002970,"sku":"BWCS-PCO300SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428091035738,"sku":"BWCS-PCO300SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428091068506,"sku":"BWCS-PCO300SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PCO300SL-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/pico-neo3-1-replacement-battery-385v-5300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
