Like others, I just leave mine plugged in all the time. As far as damaging the receptacle, even the least expensive ones will last many, many years without being damaged or worn out.

 

I have about 6 battery tenders, all plugged in all the time. Even if the bikes or other batteries are not hooked up at the time.

 

....still must be winter.......

 

Actually, I believe it's the first day of spring.

 

The hotter the weather, the faster a battery self-discharges. Many people think the opposite is true. Yes, cold weather will degrade a battery's performance in terms of cranking power, but a properly maintained battery will last longer in a cooler climate than in a hot one.

As to your unplugging dilemma, I have my two tenders plugged into a switched power bar.

 

For those compelled to break ***** - why? Sure, I get a little good-natured ribbing, but the guy's offering a suggestion. Don't like the suggestion? Move on. Like it? Take the advice. Frankly, I think I'm going the power-strip route.

 

Look Out- you worry too much. Go ride.

 

I use one of those outlet switches for Christmas lights on the tree.

 

1 hour and 7 minutes left yet...
