The pros of having a portable oxygen concentrator far outweigh the cons you will run into down the line. The one things you will need to look after exclusively with a portable unit is the power source, the battery. If the battery isn't working properly, if it drains quickly or won't take a charge, you won't be able to use your life-sustaining oxygen concentrator. The batteries you have for your portable oxygen concentrator are highly important, so you will need to know a few things to care for them in the best way.
The concentrator batteries that came with your POC are specific to that model. The batteries for portable oxygen concentrators are all lithium ion batteries, but they are not universal. When you have to replace them, you will need to order them from the manufacturer or the medical supplier, and you won't be able to find them in any stores.
The batteries by themselves can be pricey, and along with the other major repairs and replacements that will ultimately need to take place down the line, all of these things will add up. To avoid a very large replacement or repair bill all at once, take special care of your battery and note any changes in how it holds a charge.
When you're not using a spare battery, or when you are not using your portable oxygen concentrator, you should keep it plugged into the power source to hold then charge. Not only should you do this to make sure your portable oxygen concentrator will have power for the full time that you need it, but this will also help preserve the life of the battery. If a battery like this is allowed to completely drain and remain without a charge over a period of time, the battery will begin to deteriorate much quicker.
If your batteries are over 2 years old, pay attention to how long they hold their charge. Take note of the time when you take it off the charge and begin using it on your usually oxygen flow setting and periodically check to see where the battery meter is. When you begin to notice that the time is getting shorter and shorter for the battery to drain from full to less than half, it's time to consider ordering a new battery or spare battery.
Before you go somewhere for more than 3 hours at a time, and you know you will be using your oxygen concentrator for the full time you will be gone, make sure both the internal battery and the supplemental or spare batteries have a full charge.
The battery life on a rechargeable battery for the Respironics SimplyGo model is 3.5 hours, but that is if the flow setting on the oxygen concentrator is on 2. The weight of a battery isn't counted into the weight of the oxygen concentrator (unless specified), so you will need to take this into consideration when you are choosing a portable oxygen concentrator.
