Looking for an option to extend the portable operation time of your Respironics SimplyGo Mini to its maximum capacity? If so, the extended 16-cell battery is the answer. Providing double the battery life of the standard 8-cell battery, while only adding an additional pound to the total weight of the unit, patients have found that the benefits of additional battery life greatly outweigh the extra weight. The 16-cell battery is ideal for those of you that don't want an excess of additional batteries on hand, allowing you to minimize your accessory load by purchasing one 16-cell battery rather than 2 8-cell batteries. The larger 16-cell battery offers up to 9 hours of portable operation on a pulse setting of 2, with battery life ranging up to 12 hours on setting 1, 9 hours on setting 2, 6 hours on setting 3, 5.5 hours on setting 4, and 4 hours on setting 5. The battery features two battery gauges—simply press both black buttons and the LEDs will illuminate to show remaining charge. Three convenient charging options are available: AC power supply for home use, DC power supply for vehicle charging, and the optional external battery charger for charging a battery on the side. The battery weighs 2.1 pounds and has a charge time of up to 8 hours.
