If I recall Paully told me something about not leaving accessory plugs "powered" up when not used. (I leave the cigarette lighter cord to my GPS plugged in under my seat. The little LED light draws so little power, and I always have it hooked to my Battery Tender. When I remember, I try to unplug it.)
The being said, I believe Paully said this practice can frag your regulator?
However, my battery is definitely toast, and I'll be looking for a battery. Just wondering how many of you religously unplug your cigarette lighter plugs?
I've had the same batter for about 4 years, and suspect it may be the OEM unit. I've found using the Battery Tender extended the useful life of my batteries. (As previously it used to seem I always bought a new battery every year).
