    Battery charger

    I have permanently wired in a battery connector with rubber cover to the battery, with the cable just poking out of the top of the footwell (mine's LHD). I can then connect my motorbike charger to it in seconds.

    Presumably this only applies to cars that are local to your area though but?

    Here in the UK, winter temperatures are rarely below around -20C (-4F/253K) at the lowest so we probably don't need that gadgets.

    I use the same charger . My question is how long does the battery normally last on a smart without use . A week and mine seams slow to turn over?? Normal or new battery

    Our Roadie hasn't been moved for 5 weeks now. (In temps that were down to -15C)
    It JUST managed to turn a couple of revolutions, but didn't start.
    After that, it was dash flashing and solonoid clunking.
    2 hour charge from a 20A intelleigent lump sorted it.

    Smart batteries are not the biggest, and if you have after-market stereo, they go flat pretty quick (The Grundig takes zero power in stand-by ).

    In summer, we've left the ForTwo for 4+ weeks and never had a problem.

    Resistance is the enemy of electrical efficiency. With the battery up front and the starter motor behind, it's a circuit where thin wires and dodgy connections are significant. Earth connections in the return path are equally important. The battery itself has internal resistance. The lower the better and a good battery may have an internal resistance measured in micro ohms and thousand Ampere instantaneous capacity.

    Quoted 'Reserve Capacity' is important too. It's proportional to how long you've got if the charge circuit fails. Mine just got me home by keeping the engine going, but couldn't do lights as well...

    Now running on an 096 size AGM. Great for muti start/stop and no venting plumbing.

    Err...Thanks for searching old threads, but you're preaching to someone who published a manual on batteries and charging circuits 10 years ago

    I can't see any reason for you to post this almost 3 years after the thread was started, but you must get points for looking/searching old threads (which many people can't be a$$ed doing!)

    It's a sticky and where was I "preaching" to you (or whoever published 10 years ago)?

    Maybe you should go find something else to complain about.
