Genuine REF 900-102 Battery for Philips Respironics EverGo / SimplyGo – Reliable Oxygen Therapy on the Move
Exact replacement for Philips Respironics part number: REF 900‑102. Compatible with EverGo and SimplyGo (original model) portable oxygen concentrators.
If 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.
The REF 900‑102 is the factory‑spec battery for these portable concentrators. When new, it delivers 3–5 hours of runtime (depending 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.
You 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.

OEM vs. Genuine Replacement vs. Cheap Generic – What’s the Real Difference?
Not every battery that fits your oxygen concentrator is safe for medical use. Here’s how the three options compare.

Critical for oxygen therapy users
Your EverGo or SimplyGo is a life‑sustaining device. A cheap generic battery can fail without warning – leaving you without oxygen. It may also void your device’s warranty or cause error codes that disable the concentrator. The extra $50–70 for a genuine replacement is cheap insurance for your health and peace of mind.
3 Signs Your EverGo / SimplyGo Needs a New REF 900‑102 Battery
-
Shortened runtime – You used to get 4–5 hours on pulse setting 2. Now you’re lucky to get 2–3 hours on a full charge.
-
Sudden shutdowns – The concentrator powers off even though the display shows 30–40% remaining.
-
Physical swelling – The battery pack looks puffy, doesn’t slide in smoothly, or the case bulges. Stop using immediately – a swollen lithium‑ion battery is a fire risk and can damage the device.
If your battery is more than 2 years old or showing any of these signs, replace it now. Your therapy isn’t something to gamble on.

Frequently Asked Questions (FAQ)
Q: Will this battery work with my Philips Respironics EverGo or SimplyGo (original)?
Yes. REF 900‑102 is the official battery for both the EverGo and the original SimplyGo (not the Mini). Check your current battery label – if it says 900‑102, this is the direct replacement.
Q: Is this battery compatible with the SimplyGo Mini?
No. The SimplyGo Mini uses a different battery (REF 1116816 or 1116817). This battery is for the larger, original SimplyGo and EverGo models.
Q: How do I replace the battery? Is it user‑replaceable?
Yes, it’s external and tool‑free. Both the EverGo and SimplyGo have a battery release latch. Slide the latch, pull the old battery out, insert the new one until it clicks. No tools needed – you can swap in seconds.
Q: How long does a full charge last after replacement?
3–5 hours depending on your pulse setting and breathing rate. Pulse setting 2 typically gives 4+ hours. Higher settings or continuous flow will reduce runtime. You’ll get back to the original runtime when the device was new.
Q: Can I carry a spare REF 900‑102 battery for extended trips?
Absolutely. Many users carry two batteries – one in the concentrator, one charged and ready. That gives you 6–10 hours of total runtime without access to a charger.
Q: Is this battery safe for air travel?
Yes, with restrictions. At under 100Wh (likely 98Wh), it’s under the FAA limit for carry‑on luggage without special approval. Always keep spare batteries in carry‑on, never checked, and protect terminals from shorting (use original packaging or tape). Check with your airline – some may require notification or have additional rules for medical batteries.
Q: How do I charge the battery?
Use the original Philips EverGo/SimplyGo AC or DC charger. The battery charges in about 4–5 hours from empty to full. You can charge it while it’s in the concentrator or using an external charger (sold separately).
Q: What if my device shows a battery error after installation?
First, ensure the battery is fully seated (click). Plug in the charger and let it charge for 1 hour. If the error persists, try cleaning the battery contacts with a dry cloth. In rare cases, a device reset (refer to your manual) may be needed. If none works, contact us for a replacement under warranty.
Q: Do you offer discounts for buying two batteries?
Yes. For users who need extended runtime, we offer a two‑battery bundle. Contact us for pricing.

🔋 Lithium-Ion Battery Conditioning
For optimal electrochemical performance, new lithium-ion batteries should undergo 2–3 complete charge and discharge cycles before reaching full capacity.
This stabilization phase allows the internal cell chemistry to achieve balanced ion distribution, ensuring maximum runtime, stable voltage output, and extended cycle life.
After this initial conditioning period, no further full discharge cycles are required.
