Need help on assessment of effect of temperature and humidity in battery consumption | 24 April, 2018

Hi All,

Would just like to course through this concern on a product that we are contracted to assemble. It is mainly used for an automatic hand sanitizer dispensing product. By design there is a restrictive value of current that it needs to dissipate in order to minimize battery consumption (0.25mA. The thing we are seeing is that the customer's area that they (re)test the boards we shipped are on an uncontrolled area, meaning temperature can shoot up to 30-35C and RH to 60%-70% (we work in a tropical country, as well as our customers). With this, will it possible for temperature / humidity changes that causes it? The board comprises of a Programmable IC, IR sensors/photodiode for sensing and enable dispensing mounted on an FR4 PCB. None that I can't think of that could contribute to such phenomenon. Any inputs would be greatly appreciated. Thanks in advance.
