Freedom Travel Battery for CPAP Machines - Battery Only

Great product and great company!

I especially liked the prompt delivery since we were leaving on a trip for which needed a battery. I do think that there should be prominent information about storage of the battery to say battery should be used every 90 days to preserve its life. My battery was not used due to Covid restrictions and when I again needed to use it after storing it for 14 months (2 months beyond warranty!!), it would not hold a charge.

For hurricane season, this is an additional battery (#3). Have used a pair of the Freedom Travel Batteries for several years, both for travel (US and abroad with my Respironics BiPap onboard overseas flights) and for back-up power when the local utility fails or weather brings down the grid. Not using heated humidifier, typically get two 6-7 hour nights on a 100% charged battery. Batteries, chargers, and cables/connectors have proven to be easy to use and shown good reliability. Have recharged these batteries from US and European mains power (with overseas plug adapters) as well as using the vehicle adapter.

You must, must, must connect it in the exact order as instructed or it will not work. As counter-intuitive it seems, you cannot connect the wires to themselves and then to the battery and machine. Our first test run ran a ResMed 10 for a little over 3 hours with the heating and humidity on. Have not run a test with those feature off yet. Takes about 4 hours to fully recharge. This also works in the battery back-up mode as advertised. Tested cell phone charging as well. Got about four half charges to our LG phone in about 8 hours. Our iPhone was a problem. The battery kept shutting off during the charging process. Don't know if the problem was the iPhone, but that didn't happen with the LG.

Not much else to say about this battery than it simply works, which one would of course expect. A good product with some minor display improvements over the old BPS C-100 battery, but the biggest improvement over the older BPS C-100 battery is that the new Freedom battery can be used as a UPS as its software will neither use nor charge (costing one of the 4-500 lithium battery charges) unless there actually is an AC power failure. However, if buying as a standalone battery assuming you can add it in a DUAL backup configuration together with your older C-100 BPS predecessor battery and its accessories as I did, you may be a bit disappointed. The new Freedom battery software is different from the C100 so you cannot run the two together at the same time in a dual configuration. This is currently buried deep inside the manual, but CPAP.com should make that more apparent online. Also, it should have been more apparent, than if one buys a standalone Freedom battery to add on to an older C-100 package, then one will need to buy the 110V BPS Freedom A/C charger and its 12V car charger as the new Freedom battery's software will NOT allow the old BPS C-100 chargers to work. Apparently some minor power differences in the chargers. But good news is that the new chargers will charge both the old and new BPS batteries.

Even though it had been 2 years since first purchase it was very pleasant to find the right part number for the new products I bought. Every one was great. I give a five star rating.

I bought this battery for a boat/camping trip I just did for 4 nights. I bought the battery only, a dc charger (additional), and the dreamstation dc converter. I had access to power during the day so I was able to charge the battery every day. My cpap is set at 11 (took off humidifier) and for 8 plus hours a night the meter told me it was at 55% remaining so it should have been able to get me 2 nights but I never wanted to risk it being I had access to power. So at least for me it did what I needed it to do, and should work as advertised.

This is my second Freedom battery. The first one was 24v and this new one is 12v. The color went from black to white. That's the only difference I see. The battery life is most disappointing. Went on another 4 day 3 night camping trip this past week/weekend. 3800 feet in elevation at base camp and low temps around 45-50 degrees. Also, the pressure setting on my cpap is about in the middle so 5 of 10. To continue, I had 100% battery when I started. After the first night with 7 hrs of sleep, the battery went from 100% to 48%. Good right. That day we day hiked 10 miles. Second night I got 3 hours of sleep after the battery stopped at 2%. I felt miserable. On the third day I ended up hiking back out to the car 3.5 miles to charge the battery to 75% in 3 hours time and then a hike back 3.5 miles back to camp. That night with 75% of battery, my cpap only lasted about 5 hours. I am so disappointed in this battery. Does anyone have another suggestion on a better, longer lasting battery? My sleep apnea turned a supposedly great trip into a real drag. Plus, hiking with the freedom battery, my ResMed S9 cpap machine, tube and mask takes up a tremendous amount of room in my pack and adds a significant amount of weight. Adding a second battery is a band-aid solution and would even add more weight. Suggestions welcomed.

I need to send this product back. I have not been able to sleep properly for several days. Since the device will not keep a full charge.

Nice, compact, very usefull eorks great

I run 2 of these to give me about 3 nights of completely off grid power for my S8 (no heated humidifier). They are very compact and can be run and charged in tandem. I use them for hunting trips where there is no power available, I put my S8 and a pair of batteries in my packpack. If you buy this battery, be apprised that it's basically worthless without the full battery kit (Battery, charger and charging cables) this battery is only used as an additional batter and is not a stand alone unit. The packs are fully self contained with on board electronics to control charge and discharge rates plus they have a digital charge rate (percent of charge) meter built in. Lithium Ion technology, because it's fairly cutting edge is expensive, but I expect the prices to drop as it becomes more mainstream. Still a very viable alternative for powering your PAP machine totally off grid. If you camp, fish or hunt in the boonies, I recommend it.
