    I was giving Mr. ER-5 it's weekly clean and I took the battery cover
    off (because I could) and took it out to make sure it was still okay
    and holding working properly after the recent cold spell and my many
    short trips.

    I touched it with the tongs of my Gunson's Pocketmeter and it said it
    was giving out 12.86v - is that a bit high for when it's disconnected
    from the bike?

    The bike hasn't been used since yesterday so it's not been charged
    since my 4 mile bimble home last night.

    I did the same with the car battery and it was giving out 12.34v so
    I'm used to seeing something around that figure but I've not done
    anything with the bike battery before.

    Nope, that's about perfect.

    It is, and if anything it shows the car battery is getting weak.

    The car has only just ticked over to 3,000 miles.

    Mind you, it did die when it was a thousand miles old (wouldn't start)
    so the RAC came to rescue it and said it had a flat battery. The
    Nissan dealer said there was nothing wrong with the battery or the
    charging system but it's got another 2.5 years of warranty left.

    Nissan didn't think through the electrical system of this Almira Tino
    very well. If you have the engine off (but power on) it still powers
    everything as normal (including colour LCD, reversing camera, REAR
    WINDOW HEATER, etc.) which can't do the battery favours.

    I only discovered this a few weeks ago while waiting to pick someone
    up from hospital in the evening. I still had the rear window heater
    on from the journey and ten minutes after parking and listening to a
    CD I glanced in the rear view mirror to see the clear patches between
    the heating pattern on the rear window. I turned the rear window
    heater off (which I assumed went off when the car did) and then turned
    it on ten minutes later to see if it cleared the moisture off and it
    did being powered purely by the battery... Silly design.

  5. BGN explained on 31/12/2005 :
    That sounds to be fine. Anything over 12.5 after a quick discharge
    (turn lights or ignition on for a second).
    That sounds to be weak or in need of a proper charge.

  6. Indeed. Enough to make one wonder if there's a wiring fault, because
    neither my Nissan Primera nor The Doctor's Nissan Micra behaves like
    this.

  7. As Krusty said, that's fighting fit.

    Sounds the same as every car I've ever had I think, assuming by "but
    power on" you mean you had the ignition on. Has it not got a separate
    ignition key position that just powers the stereo & fag lighter socket?
    Lots of cars do it you turn it fully off then keep turning a bit
    further.

    On my Renault, everything stays on after turning off the engine until
    you open the door. It also has a lethal fly-by-wire throttle that tends
    to kill the engine when you try to do a spirited standing start, leaving
    you rolling along at 10 mph with no power and a lorry rapidly approaching.
    Perhaps it's revenge for Agincourt or Waterloo.
