The Atmotube PRO uses a 2000 mAh capacity Li-ion battery. The long-lasting battery works for up to 10 days depending on the PM measurement interval:
Always On: 1 day,
5 minutes: 4 days,
10 minutes: 8 days,
15 minutes: 10 days.
Li-ion battery lifetime
Lithium-ion rechargeable batteries require routine maintenance and care in their use and handling. Read and follow the guidelines in this document to safely use lithium-ion batteries and achieve the maximum battery life span.
Do not leave batteries unused for extended periods of time, either in the product or in storage. When a battery has been unused for 6 months, check the charge status and charge or dispose of the battery as appropriate.
The typical estimated life of a lithium-ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged to fully discharged and fully recharged again. Use a two- to three-year life expectancy for batteries that do not run through complete charge cycles.
Rechargeable lithium-ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases.
Lithium-ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage.
