Stay unplugged longer with the AirSep Freestyle External Battery. It can be used as replacement for aging Freestyle batteries or as a convenient spare battery. The AirSep External Battery is rechargeable and uses Lithium-Ion technology. It will provide up to 6.5 hours of extra battery life for the Freestyle 3 and 5.25 of battery life for the Freestyle 5.

They are compatible with the redesigned Freestyle 3 and Freestyle 5 and are available in a new color and provide clip-on option for easy transportation. The batteries can be charged at the same time 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%. 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.

These 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 or run your machine on its internal battery. The indicator light on its side will visually show you how much charge is left.
