For my project, I want a battery that can power my Particle Electron for at least 2-3 years or so. Powering the Electron through an outlet or using a solar panel for various reasons isn’t an option. The Electron will be in deep sleep for most of the day, only coming online twice a day for 1 minute to gather some data and publish it.
There’s no size constraints for the battery; even a D-cell would be appropriate. Obviously the LiPo sold in the Particle store isn’t going to cut it (may squeeze 4-5 months out of it but that’s it). I looked into alkalines, LiFePo4 and LiSOCl2 batteries but I’m simply unsure which one is going to have the most reliable performance in the long run. Also wondering what voltage to aim for; would 3.6V batteries cut it?
Right now I already have a D-cell LiSOCl2 that can power the Electron but of course can’t handle the peaks of the cellular module; was wondering if it’s worth trying to make it work however.
