    Battery Bug on R1200R (2009)

    Anyone have an Argus Battery Bug on their Hex Head? The back light comes on when the voltage is over 12.8 volts or so. This allows it to go off at the normal static voltage of 12.5V (engine running back light on, engine off, back light off). The problem is my battery puts out 13 volts even with the engine off, so the back light stay on drawing power. I gather AGM batteries put out more voltage than standard wet cells.

    Any solutions?

    Thanks,
    Scott

    I've noticed it BF. the Battery Bug itself has been receiving real good reviews over at ADV. It seems that the ability of the device has led to a chance of (if one was paying attention) noticing a battery problem somewhat in advance of the sudden death/bike won't run that seems to plague a lot of the batteries-mine included.

    I'm thinking of one to plug into the maintenance charge port on both my bikes- especially the F800, the TW has a Kick Start.

    I'll probably move this thread to Gear as it's not bike specific and may help all that wish a way to keep an eye on their battery.

    As for Scott's question, from the site-

    If the Battery Bug stays on all the time will it drain the battery? Does it time out to save energy?

    The Battery Bug consumes very little power - about 5mA for the BB-DCM series and about 3mA for the BB-SBM series. This is similar to that of the digital clock in a car, and is about the same rate that a car battery loses charge just sitting on a shelf. It would take over 5 months with no charging for a Battery Bug to substantially discharge a typical car battery.

    Are these user reviews and if so, what technical background do these users have?

    These devices sort of remind me of those conductance testers which IMO are useless. Why? They provide a quick but very incomplete status of a battery's health. They would tell me I have a "good battery" when in fact, capacity would be down to 20 or 30%. How is that a good battery?

    A true battery test is a load test and a capacity test; the latter test is time consuming.

    I have removed it.

    I went on a business trip and when I started the bike 2 weeks later, the battery was dead. I really do not think it is the battery as it fairly new has been working great before and since.

    For some magical reason, my battery sits at 13.0 volts. Which is high, but I have measured it with two meters. This causes the back light to stay on (it comes on at 12.9 volts). I goes off after a few hours, but then comes on again when the charge rebuilds. I suspect this went on and off while I was gone.

    The BB is a neat gadget, but make sure the back light stays off.

    I've had a Battery Bug on my 2009 GSA now for a while. I also now have an Odyssey Battery installed. The light stays on til it drops below 12.8 volts ( i believe). Hen it goes out. No problems with it draining the battery. Great product. I now have plans to put one on every one of my bikes.

    I suspect Scott's (OP) problem will be self-curing.. even AGM batteries rarely sit at greater then 12.8V for any length of time (and 13V standing voltage is about unheard of..)

    Been uing the bug for over 3 years to track loss of output of my stock batt in the RT. So far, though it loses punch in the cold that is reflected by the bug, it has lost nothing significant at warm temp. The bug has given me the confidence to keep using it, knowing I won't get caught out unless for some reason mine develops sudden death syndrome- whichI think unlikely for a 4 yr old battery. Will see howe it does when it gets cold this fall- replacment will be an Odyssey when needed- already use the 680 in 2 other BMWs and have used the 925 and 680 in track cars for years with no issues.
    I added a reset button to my bug by putting a temporary contact pushbutton switch in its positive lead. This prevents the bug from permanetly storing its lowest winter output reading and allows me to reset for warmer weather monitoring without disconnecting. I put up a thread on that some ime ago that can proably be found by seearch.

    Yep. Installed and the voltage drops to 12.8 after a few hours (or flipping the key on and off) and the backlight goes out.

    Thanks.
    Scott

    BTW, if anyone installs one, be sure and add a fuse. The MFG seems not to care if your bike goes up in flames.
