It backs up the PLC system that controls table positioning, surgical function programming, and SRAM memory retention. Rated at 450mAh (1.62Wh), it matches the original cell's voltage and footprint exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSurgigraphic 6000 Steris and MR200 compatibility:\u003c\/strong\u003e\n    Both units share the same PLC controller architecture and use an identical M3965 cell on the same voltage rail with the same connector footprint. No adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We confirmed the cell holds open-circuit voltage above 3.5V at rest and that the PLC BMS accepts it cleanly on float charge without throwing a voltage fault or battery alarm.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePLC hot-swap requirement:\u003c\/strong\u003e\n    Always replace this cell with the Surgigraphic 6000 controller powered on and in RUN mode. Removing the battery while the PLC is off will wipe SRAM contents instantly, forcing a full program reload from a connected programming device.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePLC losing table position memory after battery swap on the Surgigraphic 6000\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Surgigraphic 6000 PLC stores all table position presets and surgical function parameters in volatile SRAM. That SRAM requires continuous voltage from the M3965 cell to retain data — even a two-second gap will erase it. If the old cell was removed while the controller was powered down, or if it failed completely before replacement, the SRAM contents are already gone. Reconnecting power after a new cell install will not restore lost data; a full program reload from the original programming device is the only recovery path.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery alarm not clearing on the Surgigraphic 6000 after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-MnO2 cells ship at storage voltage — typically 3.3V to 3.4V — which sits below the PLC's alarm-clear threshold. The controller will not auto-dismiss the battery fault just because a new cell is seated. Allow the cell to reach at least 3.5V on the PLC's float charge circuit before attempting a manual alarm reset. Clear the fault through the programming software's diagnostic panel; the alarm will not self-reset regardless of cell voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415987322970,"sku":"BWCS-MMR320SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415987355738,"sku":"BWCS-MMR320SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415987388506,"sku":"BWCS-MMR320SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MMR320SL-1.webp?v=1779758841","url":"https:\/\/batteryweb.com\/products\/philips-tables-surgigraphic-6000-steris-replacement-battery-36v-450mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
