New to the NC700 here, just bought a 2013 model with 8000 miles on it, from a fellow forum member. Bike was in great shape, bought it, hauled it home, and , because I like to know what I am starting with, I did some work on it- cleaned the chain ( needed it), flushed the brake fluid, inspected it, etc. I also put it on my Battery Minder, which is a trickle charger. It charges the battery up, then flashes it's little green LED to tell you it is all the way charged. I let it go for a few hours, and although the red charging light was on, the battery never came to a full charge. I removed the maintenance cover, and checked voltage of the battery...( it had been off the charger overnight)...got 12.2 volts.
This got me to thinking...I had noticed that the clock had reset to 1 AM when I took it for a test ride, but just figured the PO had never set the clock. I doubted that it was the battery, since the PO showed me a receipt for a replacement battery, AND for a replacement of THAT battery, when it died an early death. It all started to make sense- I found a USB adaptor wired directly to the battery. Maybe everyone here knows that USB adaptors have a parasitic drain, ( I did), but the PO did not know. I realize it is tempting to hook it up hot, so phones, etc, can be charged while not riding, but even at 30-40mA, which is the drain of one of these units, a battery can be drained in a few days. Deep discharging of a battery WILL eventually kill it.
I did take the battery out, and give it a full slow charge, and it appears to be holding at 12.48 volts, which means it might be okay, will be checking it later today.
Hope this helps someone.
