I have a C-Tek charger that I plug directly into my bike when I get home. I find it's a good setup provided I don't forget to unplug before riding.
Have done that a couple of times which simply meant re-wiring the powerlet plug.
here's there online store for interest Fyi, I've run my battery flat several times now when tuning the air/fuel ratio, as I would keep stalling my bike in the process and having to restart etc. After a while the battery says, righto, enough is enough. I'm taking my bat and going home sort of thing. I just plug the charger in for half an hour to get enough charge to start again and finish the tuning and then put it on charge overnight. All fixed.
Not sure how detrimental this has had on my battery which is why I like the idea of the analyser posted above.
You can see in the first picture how the icons show battery level only half charged or so. Well even when I ride home from anywhere it says this but after an hour (not sure actually) the full battery icon on the right illuminates.
