Hi All,
I am working on a emeter project where the RTC battery is required to support for 20 Years.
CR2032 with 225 mAh and RTC DC1307 with worst case current of 800nA can easily support more than 20 years.
But I am not sure about the operational life of the Battery.
Vaarta states Operational life as 10 years in one of the graph.
Can anyone guide me which area I should work to get a battery with 20 years operational life?
Thanks and regards.
