So I got the 5 Amp European version of the CTEK batter maintainer/charger thinking my battery would thank me in the long run. My box sits garaged two months at a time all year (albeit in a warm climate) since it lives at my second home. So far with no battery maintence it starts right up every time even with the long periods between use. When I do drive it, it sees lots of kms.
Anyway, I'm nervous about leaving a battery maintainer plugged in and completely unnattended. What about battery ventilation? How safe are these things? I really don't want a call that my garage and car have become charcoal in my absence... should I be concerned and does anyone have some calming advice on best practices?
Thanks
