My battery is dying again - WTF is happening

[hulagun]

I use a "Sure-Charger IV". It was less expensive than the Battery Tender and as good or better quality. I have used it on 25 bikes in 10 years and it is like new still. Works great! I got it at my local dealer off the parts wall.

George - why not tell us more about your Radio Shack charge monitor and maybe post a photo?

The one I am using is from Dyna, which is excellent, costs about $45 now. Too much!
