I have a short commute so about once a month I use my BMW battery charger overnight. It always seems to need charging and sometimes it takes longer than overnight to fully recharge. I am guessing that your battery issues will be solved if you start using a battery charger regularly.

And make sure to buy a smart battery charger that will not overcharge your battery. All of the good ones have the ability to only charge when needed and not to overcharge and harm the battery.
