It provides backup power during mains loss, keeping vital signs data uninterrupted during patient assessments. The sealed lead acid chemistry matches the charge profile the 352's internal charge circuit expects.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBiolight 352 compatibility:\u003c\/strong\u003e\n    The 352 monitor uses a 12V SLA cell with a charge termination voltage around 13.8V float. The physical footprint — 182.21 × 60.74 × 23.58mm — matches the original battery bay. No connector modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge acceptance and load testing. The BMS accepted charge within normal parameters and held voltage under a simulated monitoring load without triggering low-battery cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting, let the Biolight 352 complete its full power-on self-test without interruption. The device runs a BMS verification at startup — cutting power mid-sequence logs a false battery fault 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\"\u003eDevice not completing boot sequence on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh SLA cell shipped in storage state can arrive at 12.0–12.2V — below the threshold the 352's BMS requires to confirm a healthy cell during POST. The monitor may stall at the boot screen or display a battery fault and halt. Before installation, connect the battery to a compatible 12V SLA charger and bring it to at least 12.6V. Then install and allow the full boot sequence to complete undisturbed.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Biolight 352 evaluates battery health against a charge-acceptance profile calibrated to the original cell's chemistry. A new cell hasn't yet established the internal resistance baseline the BMS uses to pass that test. The alarm clears after one complete charge-discharge cycle — charge to full, allow the monitor to draw the battery down under normal use, then recharge fully. Do not use the device clinically until it passes the self-test on that second charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381514076250,"sku":"BWCS-NK9130MD-1","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381514109018,"sku":"BWCS-NK9130MD-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381514141786,"sku":"BWCS-NK9130MD-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK9130MD-1.webp?v=1778901340","url":"https:\/\/batteryweb.com\/products\/biolight-352-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
