Background: Sleep Apnea is a common sleep disorder and Home Sleep Apnea Test (HSAT) is one of the relatively safe and convenient diagnostic screening tools of Sleep Apnea. Nowadays popular devices for HSAT suggesting to use AA batteries for power supply and disposable alkaline battery is recommended in the guideline of most devices. In 2019, a new type of rechargeable AA battery based on lithium-ion was successfully developed and put into the market. Here is the report of 2 years running, observing the performance of the new rechargeable lithium-ion AA battery, in order to proof the possibility and the advantage of the new lithium-ion battery replacing the existing battery. Method: Used Embla MPR PG with ST module to emulate an HSAT for 10 times and log the longest recording time of different battery. And analyze the voltage log of HSAT by Embla X100 in the past 3 years. Evaluate whether the new Rechargeable Lithium-ion battery is competent for HSAT by the longest recording time and the battery status during HSAT.
Result: After 2 years of continuous use, the performance of Rechargeable lithium-ion battery was similar to that of Disposable alkaline battery. And Rechargeable lithium-ion battery had a constant voltage throughout the whole recording phase.
Conclusion: The new rechargeable lithium-ion AA battery can perfectly replace the traditional disposable alkaline battery in the application of HSAT due to the un-obvious attenuation in 2 years. It also has great advantages in environmental protection and cost saving.
