SeQual Eclipse 5 Portable Oxygen Concentrator Power Cartridge (Battery)

When we bought a portable oxygen concentrator for my wife in order to be able to travel by air, we got two batteries with the unit. While this satisfied the minimum requirement for the flight we were taking, we decided that having a third battery would reduce stress as we wouldn't have to constantly be hunting for places to plug in and recharge. This battery is exactly the same in functionality as the original ones we got with the concentrator, and it is indistinguishable from them (except by the serial number). We've used it on a couple of trips, now, and it's still working perfectly. When we need to replace our batteries we know where to get them from.

It's just a battery. The picture shows the machine and 2 batteries.Plus that it's only a battery is listed last. Should be listed first and more clear.First picture should be just the battery.It's very confusing for those who can't read, can't see well and or are neuro divergent.

The battery did not work at all and can't be returned through Amazon! This is an expensive piece of medical equipment that can be a life or death matter for many patients. They are very expensive - returns need to be quick so a working replacement can be obtained. At about $500, patients cannot afford to purchase another one until they get their money back. I would not recommend this seller.
