Best CPAP Batteries
Continuous positive airway pressure (CPAP) machines are the most common treatment for sleep apnea. Virtually all CPAP machines use a power supply that plugs into an electrical outlet. For this reason, most CPAP machines do not require batteries.
However, sometimes sleepers may need or want to power their CPAP machines by battery. For example, some sleepers may require a battery while camping or traveling to places that don’t have readily available American electrical outlets. A battery can also serve as a backup power source in the event of a power outage.
Choosing the right CPAP battery is an important purchase decision. Batteries capable of powering CPAP machines are not cheap, so you want to invest in one that is long-lasting and compatible with your specific CPAP machine.
CPAP Machine Battery Compatibility
Purchasing a battery that’s compatible with your CPAP machine is of utmost importance. If you purchase a battery that isn’t compatible, it could damage your machine or simply not work.
We’ll highlight popular CPAP machine models and batteries compatible with each machine type.
What to Consider When Purchasing a CPAP Battery
When shopping for the best CPAP battery, consider many different factors. Most importantly, the battery you choose must be compatible with your CPAP machine. Secondly, your battery’s run time should exceed the time you spend sleeping, so your machine doesn’t lose power during the night.
Other factors vary in their importance depending on the person. Others might want to invest in a battery that’s long-lasting, so its durability and warranty could be of importance. Sleepers planning on using their battery while camping or traveling do best with a highly portable battery that charges quickly.
Be sure to consider your own unique situation and preferences when shopping for a CPAP battery. The best CPAP battery is the one that most satisfies your needs.
Machine Compatibility
Finding a battery that’s compatible with your CPAP machine is an absolute must. Not all portable batteries are compatible with all CPAP machines.
Some CPAP machine brands make their own compatible portable batteries. Be sure to research compatibility before purchasing a battery. An incompatible battery might not power your CPAP machine properly. An incompatible battery could also damage your CPAP machine.
Battery Capacity
Battery capacity is a scientific term that refers to a battery’s ability to store power. Battery capacity is usually measured in terms of milliamps per hour (mAH). Generally, batteries with a higher capacity also have a longer run time. External factors, such as temperature, can impact a battery’s capacity. Most sleepers want a battery with a higher capacity to power their CPAP machine.
Run Time
Run time refers to how long a battery can power a device. Run time is important when batteries are being used to power CPAP machines. If your battery’s run time isn’t long enough, your battery could run out of power while you’re using the CPAP machine. Most CPAP batteries provide enough power for 1 to 3 nights of sleep before they require recharging.
Some sleepers want a battery with an exceptionally long run time, so they don’t have to recharge the battery every day. Batteries with extra long run times tend to be more expensive than those with shorter run times. A long run time battery could be necessary for some sleepers camping or traveling, who can’t access a wall or car outlet every day during their travels.
Charge Time
Charge time refers to how long a battery takes to recharge. Charge time can be important, especially to people using a CPAP battery while traveling. When a person isn’t in one single place or near an outlet all day, having a battery that charges quickly is required so it can become fully charged. If a battery isn’t fully recharged during the day, its run time will be diminished, and it might not be capable of powering a CPAP machine all night long.
Portability
Portability matters to sleepers wanting a CPAP battery so they can use their CPAP machines while camping or traveling. Size, weight, and design impact the portability of a CPAP battery. Smaller batteries take up less space in a bag, which is a plus, especially when traveling in situations that limit luggage space. Lighter-weight batteries help keep bags light, which is important when camping or in other travel situations that require a person to carry their luggage for longer distances.
Durability
The more durable a battery is, the longer lifespan it will likely have. Some battery manufacturers share how long their battery is guaranteed to last in terms of how many times it may be recharged. Durability refers to more than just lifespan, however. The design and shape of a battery also factor into its durability. A durable battery won’t break easily or become damaged through regular use.
Price
People on a budget care about the price tag associated with their CPAP battery. CPAP batteries generally run between $200 and $600. Unfortunately, less expensive batteries tend not to perform as well. Less expensive batteries typically have shorter run times and longer charge times. Of course, this is a generalization and not a rule. Sleepers shouldn’t make assumptions about the quality of a battery or decide which battery to purchase based on price alone.
Warranty
Most CPAP batteries come with a 3-year manufacturer’s warranty. Generally, these 3-year warranties cover defects in the battery but not accessories or damage or problems caused by use. Sleepers seeking a CPAP battery should familiarize themselves with details of the manufacturer’s warranty before making a purchase.
