I have had my 999 for a few months now, and noticed something that I thought other owners might be able to help me with.

Before I start the bike the displayed voltage ranges between 11.9 and 12.2 volts. 12.2 would be after a longer ride, turning the key off for some time, then restarting. Less than that would be after a few shorter trips that I usually take. Normally it is 12.0. The bike always has enough juice to start (sometimes just enough). I wonder if the battery is nearing the end of its life (2+ years old). After starting the alternator rises the voltage to 14.1 as expected.

So the question is: in normal use what voltage do you usually have displayed before hitting the starter button?

Thanks in advance.

I have a 749. My battery after turning the key is in the 12's. After starting, 14.1. I just bought a Yuasa a few months ago.

Re: (RI749)

Mine is 13.9 all the time, but I have a battery tender on it all the time when it's just sitting.

Re: (viper1)

We replace them if they don't make at least 12.8 when not running
