Attempting to charge this battery poses a significant risk of fire or explosion. Always replace a depleted unit with a brand-new, original Yokogawa pack.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the DCS provide an alert when the battery is failing?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. Yokogawa CENTUM systems monitor the backup battery voltage. When the voltage drops below a specific threshold, the system triggers a \"Battery Low\" alarm on the Human Interface Station (HIS), allowing maintenance teams to replace the unit before data loss occurs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre there any special handling requirements for this battery?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAs a lithium-based product, you must store the S9185FA in a cool, dry place away from direct sunlight. Do not short-circuit the leads or expose the pack to temperatures exceeding 100°C, as this will damage the internal chemistry and safety seals.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43194953531482,"sku":"S9185FA","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/204._9229f2fd-353f-4301-8422-aaf259039833.jpg?v=1775721625","url":"https:\/\/www.spareoil.com\/products\/s9185fa-yokogawa-dcs-system-memory-retention-battery","provider":"SpareOil Automation","version":"1.0","type":"link"}
