Ensuring uninterrupted sleep apnea treatment is crucial, and the right power solution plays a key role. In our guide, we delve into the top choices that promise reliability and peace of mind. Whether you’re at home or on the go, these battery solutions are designed to keep your CPAP machine running smoothly, safeguarding your sleep therapy against power interruptions.
What is a CPAP battery?
Patients who suffer from obstructive sleep apnea may experience difficulty and annoyance due to power outages and travel plans (OSA).
CPAP backup batteries are specifically designed to provide power to a CPAP machine in the event of a power outage or other disruption to the main power source. CPAP batteries are a risk-free alternative that allows patients to keep using their CPAP devices without experiencing any issues.
These batteries are typically rechargeable and are used in conjunction with a power inverter, which converts the battery’s DC power into AC power that the CPAP machine can use.
Types of CPAP Batteries
Traditional lead-acid and lithium-ion batteries are the two main types commonly used to power CPAP machines.
Lead-Acid Batteries
Lead-acid batteries are the most common type used in CPAP backup systems. They are generally less expensive than lithium-ion batteries but also heavier and have a shorter lifespan. Lead-acid batteries require regular maintenance, such as checking the electrolyte level and keeping the battery charged, to ensure they last as long as possible.
Lithium-ion Batteries
Lithium-ion batteries are increasingly popular for CPAP backup systems due to their lighter weight and longer lifespan. They are also more efficient and can hold their charge longer than lead-acid batteries. However, lithium-ion batteries are typically more expensive than lead-acid batteries.
Choosing the correct type of battery for your specific needs is essential. Consider factors such as the size and weight of the battery, the expected lifespan, and the charging and maintenance requirements when making your decision.
What Battery Size Do I Need For My CPAP?
Most CPAP machines can be powered by a CPAP battery pack that operates on either 12v or 24v, and their power needs range from 30 to 90 watts.
Your machine’s requirements can fluctuate depending on the type of machine you use (i.e., CPAP, APAP, or BiPAP) and the pressure settings you utilize. The power that is normally required for more complex operations, such as an automatic ramp or leak detection, is significantly higher. Your power requirements could also shift based on the accessories you use, such as a humidifier.

Things to Consider When Purchasing a Battery Backup for CPAP
There are a few things to remember when looking for a new Battery Backup for CPAP. Below you can find a guide to help you choose the best CPAP battery product that fits you.
Compatibility
Some machines cannot work with certain types of batteries. Before looking at customer evaluations, you want to determine what batteries are appropriate for your CPAP machine.
Because most manufacturers create batteries compatible with medical equipment from the same brand, you will need to research before purchasing any batteries.
If you buy a battery that is not designed for your device, it has the potential to cause damage to the gadget and may even prevent it from being powered at all.
Size
The vast number of these portable CPAP batteries are transportable. However, some are more manageable in size and weight than others.
Check the weight and dimensions of each option before settling on the one to purchase. For instance, you should select a lightweight model if you intend to bring it with you on a camping trip.

Battery Capacity
The capacity of your battery can be expressed in milliamps per hour or watts per hour; the higher the capacity, the longer the battery will continue to function after being recharged.
Most consumers choose a battery with a bigger capacity because they want it to last longer and don’t want to charge it as frequently.
Warranty
Most of the warranties for batteries are for one year, and it is highly unusual to discover a product with a good warranty for two years. This guarantee, in general, only covers defective batteries and does not pay for harm that results from regular use.
Suppose you find a product with a lengthy warranty that covers more than this, in addition to looking into whether or not it is compatible with your device. In that case, you should also investigate its other features.
Because most insurance providers do not pay for these batteries, your primary concern should be purchasing an excellent quality item with a good warranty.
Charging Duration
The amount of time a battery can run depends on several elements, including the pressure setting, the altitude level, your machine, and whether or not you use a humidifier. These devices have a single charge that will last for one to two nights of use.

Test The Battery Regularly
It’s a good idea to test your battery regularly to ensure it functions correctly. You can do this by using the battery to power your CPAP machine for a short period and checking that it can run for the desired length.
How to Calculate the Size of the Battery You Need?
Divide the power consumption of your CPAP machine (in watts) by the voltage of the battery (in volts) to determine the current draw (in amps). Then, multiply the current draw by the runtime you need (in hours) to determine your battery capacity (in amp-hours).
For example, if your CPAP machine has a power consumption of 50 W and you need it to run for 8 hours on battery power, you will need a battery with a capacity of at least 400 Ah.
Disclaimer: The calculations are based on the information we provide and may not be accurate or appropriate for your specific situation. You should always consult a qualified professional before making decisions about your CPAP battery backup system.
