Just picked up my Volt last week, loving it so far. Just a quick question that I couldn't surmise the answer for from the manual. My wife will be doing the majority of driving, going to work each day as I work from home. The question is, she only has to drive about 22 km a day (13 miles) so she has a lot of charge left at night. Is it a better idea to charge it back up to full each night or just leave it and charge it every other night? I know about the thermal management system and the extreme temperatures so I know it's probably best to charge it every night in the heart of the summer and in the winter but in the moderate spring and fall what would be best for the long term benefit of the battery, a nightly charge or a bi-nightly charge? Thanks for any info.
