Description
Use the AirSep Freestyle External Battery as a convenient spare battery for the NEW Redesigned AirSep Freestyle Portable Oxygen Concentrators, or as a replacement battery for aging Freestyle batteries. The AirSep External Battery is rechargeable and uses Lithium-Ion technology. With the Freestyle 3, the battery provides up to 6.5 hours on a setting of 1 and 3 hours on a setting of 3. Using the Freestyle 5 can give you up to 4.25 hours on the setting of 1 and 1.25 hours on the setting of 5.
The FreeStyle batteries can be charged while plugged in to an AC or DC source or in their personal charging dock separate from the unit. They are a great alternative for users who require more battery life for their portable unit. Each battery takes approximately 5 hours to recharge from 0-100%. The batteries will also inform you immediately when the charge is getting low so that you may have time to go to a power source and charge the battery. The indicator light on its side will visually show you how much charge is left.
