About battery tenders… I have two, they’re different makes.. I have a habit of not leaving them connected all winter, the leads running across the garage sometimes get in the way.Jerry’s so smart. Just another thing us in California don’t think about. But a good battery tender is on my list that is a waay better solution than pulling a fuse
The other year I forgot to give my Yamaha’s battery a boost, went to it and it was flat. I connected the battery tender and it did not recognise there was a battery, tried the other tender same result. It seems when the battery’s voltage is too low the tenders didn’t recognise it. My solution was to use my old car battery charger for about an hour or so, I then connected the battery tender and it worked.
That battery was still working well over a year later when I sold the bike😀
