    Yes I think I will be buying a new battery,
    *Im going to give it a last go though, at this stage, even if it works, Id be concerned about relying on it, if I can get it going I'll see how the charge stays,

    where is a good place to buy a battery anyone?
    Im thinking bricks and mortar but cost is a factor, so as cheap as possible for as good a battery as possible, so maybe online.
    Look around for a MotoBatt battery, easy to spot they are yellow.
    AGM batteries and more resistant to self discharge then the standard lead acid batteries.
    Lots of shops sell them.

    any idea what it will cost me for a bike battery, is there much of a range of price?

    The last MotoBatt I got was a MTX9 and I think it was around 60-70 or so.
    I think they are very reasonable pricewise compared to a basic sealed lead acid.

    Mine is a lead acid, it was fine when it was in use, but Im not sure how much cheaper they'd be
    its definitely a replacement, just not coming back to life.

    Batteries left dead for a day or two can be unrecoverable.
    I also bought a good charger, already had a Optimate but bought a Procharger from Louis as well. It does Lithium Ion as well as SLA, AGM etc.
    It can recover some batteries but they'll never be 100% again.

    On a previous bike I had heatd grips wired direct to the battery. I went away on two weeks holiday to spain and left the grips switched on by accident. Came home and not a peep out of it, not even a neutral light. Charged it overnight, got lights but not enough to start it. Then left it on charge for 2 days solid and it worked fine, used the bike every day and sold it over a year later with the same battery.
    So try leaving it on charge for a couple of days.

    I have two battery chargers now, both can be left connected for a long time with no ill effects, generally I find that if batteries are used regularly they last a lot longer than ones that aren't used regularly.
    I highly recommend Optimate chargers, I have mine for years now and it still works well.
    I got the Louis Procharger XL as well as I needed one for the car that was intelligent and I figured that as it does LiPo and LiIon that it should future proof me somewhat...

    Anyone used those Oxford solar chargers?
    Are they any good?

    Probably worth leaving the battery on a charger overnight or longer to see if the voltage will increase to 13.5 or so. If it still can't turn the starter over probably time to think about buying a new one. There are plenty of battery revival vids on you tube, but expert advice is that in the best circumstance, they can only get a battery back to about 80% power and but sometimes they don't work at all.
