Come out from work last Friday and my battery was stone dead. No dash, lights, no clicks, no nothing. Wifey picked me up, but at least she got a good dinner out of the deal.
Checked the battery that evening and it was reading something like 6.4 volts (forget, didn't write it down). Threw it on the big automotive charger for a few seconds and it was taking about 8 amps and the voltage was climbing, but would sag (start dropping) as soon as I pulled off the charger.
Pulled off the big charger and put on the BatteryMINDer - the one with the pulse desulfator electronics. Looks like this one, but mine is an older model.

These things are worth their weight in gold. I have saved many many batteries with this thing.
Anyway, voltage kept climbing ....slowlyyyyy. Left the charger on overnight and the voltage was up to about 13.4V in the morning. Went rowing with my wife Saturday morning and by the time we got back, maybe 11:30, the desulfator circuitry was going, which means this little 1 amp charger was able to bring the voltage over 13.5 volts which triggers the pulse circuit.
Drove back into the city, installed the battery and the bike fired right up no problem. I was paranoid that the bike's charging circuit was dead and it was just running off the battery. Checked the voltage when I got home, and the battery was still about 13.5V (right after running - no rest time). Restarted the bike, checked the voltage running and the voltage goes up to 14.3V, indicating the charging system is running fine (and the battery is not taking much current).
Been riding a few more times and the battery seems to be doing just fine.
This is the original Yuasa AGM/gel cell, so it's 3+ years old. I'm not surprised that the battery could be going, but not surprised either that it came back to life with the BatteryMINDer. What I can't quite figure is how it died in the first place. I'm pretty sure I did not put the key in the parking lights position because I'd notice that in the dimly lit parking garage. Any ideas?
