Currently we are working on implementing the battery and load profiling feature for the GUI. This will enable actually measuring the impact of peak currents on the battery capacity. The load profile will be analyzed for peak currents, duration and magnitude of the peaks, the voltage recovery time and other factors to arrive at the capacity degradation. This along with the battery model will predict very accurate estimate of the battery life.
We are starting with Lithium 3V batteries like CR2032 to begin with. The battery models will be ASCII files which would be uploaded on the website as and when available. This way the GUI can be released with just one battery type and then the users can add batteries later.
Upcoming releases will also feature options to enable the users to profile the batteries so that they can make their own models. If they share the models with the community, we can soon build exact battery models which would benefit the whole community.
