It replaces OEM part 533-000132, which Logitech uses across this headset family. Fits the same physical slot and connects to the same internal header as the original cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG933 \/ G533 \/ G935 \/ G635 platform fit:\u003c\/strong\u003e\n    These four headsets share the same 3.7V single-cell Li-Polymer architecture, connector pitch, and PCB layout. Logitech uses one cell across the range, which is why OEM part 533-000132 covers all four models 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 charge and discharge cycles on the G933 platform. The BMS accepted the pack without fault codes, balanced current draw across both the audio DSP and the 2.4GHz radio circuit, and held voltage within the expected window under combined load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station procedure:\u003c\/strong\u003e\n    Seat the headset in the base station and let it complete one uninterrupted charge cycle before use. The base station logs the new cell during this cycle — skipping it causes the charge indicator to misread state-of-charge and cut the session short before the cell is actually depleted.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the G933 cuts out mid-session on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G933 runs two simultaneous loads: the audio DSP and the 2.4GHz wireless radio. Under peak combined draw — loud audio plus active wireless transmission — the cell must deliver current spikes that a degraded or unconditioned battery handles poorly. The BMS interprets a voltage sag during these spikes as a low-cell event and cuts output to protect the cell. On a new replacement, this typically clears after two to three full charge cycles as the cell stabilises its internal resistance. If cut-outs persist past five cycles, check that the base station firmware has not flagged a charging fault.\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 replacement cell ships at storage voltage — roughly 3.6V — not at full charge. If the base station reads this as a charged state and the indicator goes green quickly, the cell has not actually completed a charge cycle. The headset then draws down the remaining capacity fast and the BMS shuts off output before the user expects it. Fix: place the headset in the base, ignore the indicator, and leave it charging for a minimum of three hours on first use. After one full cycle the indicator will accurately reflect real charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428128718938,"sku":"BWCS-LOG933SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428128751706,"sku":"BWCS-LOG933SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428128784474,"sku":"BWCS-LOG933SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LOG933SL-1.webp?v=1779934222","url":"https:\/\/batteryweb.com\/products\/logitech-g933-replacement-battery-37v-1200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
