Compatible with EverGo and SimplyGo (original model) portable oxygen concentrators.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIf you use a Philips Respironics EverGo or SimplyGo for oxygen therapy, you know they keep you active. Whether running errands, working, or traveling, they fit into your daily life. But when the original battery starts to fade, that mobility turns into anxiety. You watch the gauge instead of enjoying your day.\u003c\/p\u003e\n\u003cp\u003eThe REF 900‑102 is the factory‑spec battery for these portable concentrators. When new, it delivers 3–5\u003cstrong\u003e hours of runtime (depending\u003c\/strong\u003e on flow setting and breathing rate). After a couple of years of regular use, capacity drops. You might get only 1–2 hours, or the device shuts down at 30% without warning.\u003c\/p\u003e\n\u003cp\u003eYou don’t need to pay Philips's premium price ($320+). And you absolutely cannot trust a $60 generic that might swell, trigger error codes, or fail mid‑trip. This genuine replacement battery provides medical-grade reliability like the original. Plus, it costs less.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e\u003cspan\u003eQuick Specs – What You’re Getting\u003c\/span\u003e\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003ctable style=\"width: 100%; height: 293.907px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 22.553%; height: 19.5938px;\"\u003e\u003cspan\u003eSpecification\u003c\/span\u003e\u003c\/th\u003e\n\u003cth style=\"width: 74.5898%; height: 19.5938px;\"\u003e\u003cspan\u003eValue\u003c\/span\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 19.5938px;\"\u003e\u003cspan\u003ePart Number\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 19.5938px;\"\u003e\u003cspan\u003eREF 900‑102\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.1875px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 39.1875px;\"\u003e\u003cspan\u003eCompatible Devices\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 39.1875px;\"\u003e\u003cspan\u003ePhilips Respironics EverGo, Respironics SimplyGo (original model – not Mini)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.1875px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 39.1875px;\"\u003e\u003cspan\u003e\u003cb\u003eReplace Part Numbers\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 39.1875px;\"\u003e\u003cspan\u003eREF 900-102\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 19.5938px;\"\u003e\u003cspan\u003e\u003cb\u003eCompatible Machines\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 19.5938px;\"\u003e\u003cspan\u003eFor Respironics EverGo Simply Go Oxygen Machine Battery DYNA-WJ CM2\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.1875px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 39.1875px;\"\u003e\u003cspan\u003eCapacity\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 39.1875px;\"\u003e\u003cspan\u003eMeets or exceeds original spec (approx. 98 Wh – check original label)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 19.5938px;\"\u003e\u003cspan\u003eChemistry\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 19.5938px;\"\u003e\u003cspan\u003eLithium‑ion (medical‑grade cells)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 19.5938px;\"\u003e\u003cspan\u003eVoltage\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 19.5938px;\"\u003e\u003cspan\u003e14.4 V nominal\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.1875px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 39.1875px;\"\u003e\u003cspan\u003eSafety Features\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 39.1875px;\"\u003e\u003cspan\u003eOver‑charge, over‑discharge, short‑circuit protection, temperature monitoring, cell balancing\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 19.5938px;\"\u003e\u003cspan\u003eExpected Runtime\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 19.5938px;\"\u003e\u003cspan\u003e3–5 hours (pulse setting 2, typical breathing)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 22.553%; height: 19.5938px;\"\u003e\u003cspan\u003eCompliance\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 74.5898%; height: 19.5938px;\"\u003e\u003cspan\u003eIEC 60601‑1, UN38.3, CE, RoHS\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan\u003eA healthy REF 900‑102 battery restores your EverGo or SimplyGo to its original runtime – enough for a morning out, a long medical appointment, or a cross‑country flight.\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e\u003cspan\u003eOEM vs. Genuine Replacement vs. Cheap Generic – What’s the Real Difference?\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eNot every battery that fits your oxygen concentrator is safe for medical use.
