I've read a number of places that battery temperature affects battery capacity-- that a cold battery will see a temporary reduction in capacity. I'm confused. I've been closely monitoring my economy and charge cycles this winter because I am temporarily doing a long commute in the Northeast (aka, the frozen tundra right now-- it was -8 on my morning commute today). Anyhow, last summer I was getting between 240 and 246 gids on a full charge (rarely is it 246). This winter, even in temperatures consistently well below freezing, I've been getting between 236 and 241 gids on a full charge (usually 241, although 238 this morning). I don't see a huge difference in the number of gids that I get on a full charge. I also don't typically notice a correlation between battery temperature and economy, except when my battery got down to 10* today (until it warmed up to 15 or so), but 15* or 40* (in cold ambient temps), I don't see a difference. I do struggle to get economy anywhere near my summertime economy, though, and I notice a huge impact from the wind direction and speed (I swear more so than the summer)-- it seems to affect my economy more than a slight bit of snow on the road. Am I missing something? I was expecting to see a greater capacity loss to explain my reduced winter economy.
