Each OxLife Liberty 2 Concentrator can hold one battery at a time. Buy extra batteries for additional time away from fixed power sources.
Batteries will recharge in the concentrator whenever it is connected to AC or DC power. In addition batteries can be recharged outside of the concentrator using the Battery Charger. Each battery includes an LED "fuel gauge" to help determine current battery charge.
USAGE: To Maximize Battery Life: Store battery in a cool, dry place when not in use. Store battery with at least 50% capacity remaining. If using multiple batteries, uniquely label each battery to ensure each battery is rotated equally. Charge batteries every three (3) months when not in use.
