It fits models 0227-0353, 02270353, and 0227040203. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSurgical table platform compatibility:\u003c\/strong\u003e\n    The 0227-0353, 02270353, and 0227040203 share the same 22.2V battery rail, connector pinout, and BMS handshake protocol — one battery services all three variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the Maquet BMS initialisation sequence and confirmed the charge IC accepted the cell, reported state-of-charge correctly, and held voltage within spec under a simulated table-drive load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the surgical table to complete its full power-on self-test without interruption. Maquet's BMS runs a chemistry verification at startup — cutting power during this sequence writes a fault flag that persists until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS learn cycle on the 0227-0353 — why one full charge-discharge matters before clinical use\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eMaquet's battery management system calibrates its state-of-charge model against the actual cell chemistry during the first full cycle. A new cell arrives with a conservative charge history the BMS hasn't yet mapped. Until one complete charge-to-discharge cycle runs, the BMS may report capacity at 85–90% even on a fully charged pack. Run a full charge, then operate the table until the low-battery threshold triggers, then recharge fully — after that cycle the BMS reads accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow-battery alarm fires immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS self-test threshold is calibrated for an OEM cell that has completed multiple charge cycles — a fresh replacement hasn't passed that internal benchmark yet. The alarm is a BMS fault flag, not a sign the cell is defective. Run one full charge-discharge cycle on the table and allow the self-test to complete uninterrupted. After that cycle, recharge to 100% and the alarm threshold will clear at approximately 24.5V open-circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381456437338,"sku":"BWCS-MAT353MD-1","price":213.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381456470106,"sku":"BWCS-MAT353MD-2","price":250.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381456502874,"sku":"BWCS-MAT353MD-3","price":278.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MAT353MD-1.webp?v=1778900983","url":"https:\/\/batteryweb.com\/products\/maquet-0227-0353-replacement-battery-222v-8800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
