    Deltran battery tender plus

    Hi,
    I have a GSA 1200 2016 and I would like to know if the battery tender plus is adequate to charge and maintain the battery.
    It works fine for my other non BMW bike, but it doesn’t seems to be too efficient for the GSA.
    The tender is connected directly to the battery using an SAE cable.
    Thanks for any information.

    Ultimately I found the Tender Plus wasn’t up to the job on my 11S.

    The CTEK which replaced it seemed to be a better solution...

    Yep Works fine for me.
    What make you say "doesn't seem to be too efficient for GSA"??

    I do not think it recharge the battery fully. The red light goes off pretty fast, so technically it is fully charged, but there is not enough power to start the bike unless I leave it one day on thr green ligth to maintain.

    Works fine on m 2012 GSA and my 2016 RTW. Ironically it seems to take a bit longer to get fully charged on my 2012 CamHead. I have 2 Units and both work on both bikes.

    Consider replacing the battery itself. It should generally have enough power to start the bike even with no charger at all.

    Quite possible to “float” a charge across the liquid and fool the charger. I agree on an actual battery problem. Being a 2016 you should have a 2 year warranty on the battery.

    I can’t recall the details from an earlier thread on this subject. But as I recall the Deltran doesn’t put out a high enough charge rate for gel type batteries. That thread lead me to a discussion of CTEK chargers, the CTEK solved the problem on my 11S. Which was a good thing since accessing that battery was a real PITA. The CTEK has different settings, the manual recommends a specific selection for BMW batteries.

    I wonder what's different about the AGM batteries BMW uses?
    BMW replaced both of our batteries this fall in our 2016 R1200RS after they failed the load test.
    The original battery still sounded good when starting but decided to have them checked when Debbie's bike was doing the double tap start more than normal.
    I use the Battery Tender Plus on both bikes.
