Just curious if the battery tender can drain a good battery if the power goes out or if it is smart enough NOT to let it drain through the lines?
We lost electricity in our second major snowstorm in a week---(10 Inches) --(12 inches a week earlier)
This power outage was 36 hours and my Spyder was on a tender in the barn.
Any comments?
Thank you ahead of time!
