Battery life when cold

[rod9301]

I have a500 ah battery, and i noticed that the range got smaller in the last couple of weeks

Temperature is lower, 45 degrees Fahrenheit instead of 85. Could this be the cause?

Generally, yes.

Almost all batteries suffer in low temperatures, camera batteries, AA batteries, etc. I notice it when cold (around freezing) that range suffers.

Yes, and besides the battery being less efficient in the cold, many other factors will also contribute to reducing range, some more than others, but they all have a negative effect on range.
- Dense air in cold weather gives greater drag.
- You wear more clothes = larger surface for wind resistance.
- All lubricants in the driveline are stiffer = more loss.
- In winter, it typically blows more and more often, so you have more wind resistance.
- Wet roads provide greater rolling resistance.
The factors are not listed in order of priority, and there are probably more factors, but that's all I could think of right here and now.
