Temperature vs Battery Voltage


#1

I become fascinated by silly stuff so forgive me…

I’ve been watching my Sky’s battery voltage since installation in January. I realize that battery voltage changes with temperature but when I overlaid the temp and voltage graph screenshots in Photoshop, I was surprise at how close the voltage tracked with the temperature. The batteries are like their own self-contained thermocouples.

Most cells react adversely to cold.

I have also noticed this over time and accept the performance as all batteries are like this: Now if only the units had thermal insulation around the batteries we could eke out a few more volts over life. :slight_smile :wink:
