I have my auxiliary ports (cig lighter and dedicated dual USB port) off of a
relay, but added a switch to bypass the relay to maintain power on the
ports when traveling to charge cell phone/MP3 player at night PLUS keep my
GPS hot continually so that it will record a track continuously. I usually
don't activate it unless I am on an extended trip. I use a single LED
voltage monitor:

Which I like very much. Visible in most any light condition.
Voltage Output
>15.20 Green/Red alternating (over-voltage)
>13.20 Green (charging)
>12.45 Amber (75% plus)
>12.25 Red slow flash (50% approx)
>12.00 Red 2 flashes, repeat
>11.80 Red 3 flashes, repeat

I installed a relay, 1st day I got my klr, But now think I will either take
it out, OR Install a bypass, switch.
I get to a location , like a Rustic campgrounds, or just in the wood's etc,
and realize my Phone is about dead, and can NOT charge it.
So I think I will at least install a Bypass, for that kind of thing. ($3.+-)

I think that those voltages are for when the battery is at its current full
charge condition. Maybe after an overnight on the charger or after an hour
or more ride.
Instead of "voltage to %charge" should be possibly be "fully charged voltage
to % of rated capacity". Which makes me feel better about my current battery
it hasn't had more than 12.4 for the last couple of years. But recently my
friend's battery after an hour's ride was showing 11.8 and would not crank
his bike.
YMMV but if I run the AGM battery--on either the '99 I used to own or the 08
I have--to 11.1 (due to stupidity/abuse on my part) it would start the bike
in "typical" conditions. With NAPA 15w50 synthetic in it even.
For more fun typical charging voltage for both the '08(65k miles) and
'99(32k miles) were right around 14v. Measured with Garmin 276 (attached at
the battery terminals, neat display field on the map screen) that I had
checked with a digital multimeters. But if I turn my '08 high beam on (stock
wiring) it goes _up_ to 14.5, _if_ the battery is fully charged when I do
it.
If I had run the voltage down to that stupid level it wasn't going to see
14v until more than an hour of running. I typically run it down to high 11's
when I am at a campground for a few days and use it to charge the notebook
computer and such. It would be charging the battery at ~12v and slowly go up
to 14v.
I get a little anal after a few push starts when I wasn't paying as much
attention as I should have to what I was doing.
Hiking days in a state or national parks are murder on my battery's. That
and leaving the dang GPS on the bike in the on setting, oops. One of these
days I will install a relay to prevent that. Nope to lazy.
For what little it is worth,
Mike Nasca

I seem to remember reports earlier on this list of the pre-07 models KLR
running higher voltages, like around 16v. This was thought to happen
because of the lower amp output of the charging systems. Does anyone else
remember this or has anyone checked the voltage on their charging system and
how would that fit in with this file?

The chart is now available in the Files section. Thanks, Lee. There is a
little more info there, but here's the meat of it:
Battery
Voltage %Charge
12.63 100
12.54 90
12.45 80
12.36 70
12.27 60
12.18 50
12.09 40
12.00 30
11.91 20
11.82 0
