    Battery / charging issue?

    Technical help please:

    I haven't been using the bike much if at all through the winter but when I have it's usually had a reasonable run.  I haven't been using a battery optimiser though.

    But starting it, it's sounded a bit laboured as if the battery was a bit low.

    On Friday I went to go for a ride and there was no juice in the battery at all. Tried to turn over and then was completely flat.
    There's no alarm or anything else to drain the battery other than a wired in Satnav, heated grips etc.

    I've put the battery on a ctek charger and it's showing that it's back to fully charged.
    Does this sound like a RegRec issue? I have a new battery ready to go but am worried that that's not the issue.

    Do people think this is just lack of use through the winter or is there another issue that I might be missing?

    I'm off to Spain on Friday so a bit nervous about what to do.

    Just keep battery connected to Optimate when you know you are not going to ride it for a period. Otherwise, it sounds normal that it will go flat over long unused period. I say this from experience on previous bike, but learnt from that a couple of times. Since then, I just leave connected when I park it in garage and never have problem.

    So you don't think that there's an underlying issue? The battery just needed some help.

    Modern VFRs aren't prone to the reg/rec issues the first 800s had so unless it is a rogue one, I suspect it is as Geoff says, lack of use.

    Might be worth taking some jump leads with you on your tour though  :156:  :016: :164:
    98 VFR800 - 130,000 miles, 08 VFR800 - 76,000 miles, 15 VFR800X - 44,000 miles (all sold)
    14 VFR1200 - 20,000 miles
    18 VFR800X - 16,000 miles
    01 VFR800 Fi-1 - 0 miles (yet)

    Thanks.

    I'll stick on the new battery for peace of mind and maybe rake the ctek charger with me just in case!

    Reg rec issues alive and well in VFRs but different to original overheating and flattening battery whilst in use.

    Mine had a leaky diode and would flatten the battery over 48-72 hours if left standing.

    It took about 6 months to find someone who had the wits to sort it.

    Bike not missed a beat in the 3 years since.

    2015 MKII, failed at 28,000 miles, now nearly at 40,000

    Thanks Barney. Useful to be aware of that.
