    Batteries on motorbikes do not seem to last long

    I am not sure why but I seem to keep on replacing my motorcycles batteries. Seems a generic comment but I have 3 bikes and have to replace at least one battery per year on average. Should I think of investing in a trickle charger? if so what sort, do I have to disconnect the battery to trickle charge?
    My thoughts are that by not using the bikes very regularly, destroys the batteries.

    Trickle chargers can connect up to auxilary plugs (often hidden behind the number plate), so you don't need to take out the battery, literally takes less than 30secs to connect up in a well set up shed. You might be able to connect all three to the same trickle charger too. I know Liam at fastbikegear has good knowledge about the batteries and trickle charges he sells.

    Also, do the bikes have clocks or anything else that would create a continuous drain on the battery? as that won't help things at all.

    Lead acid and their derivatives don't like sitting around. They self-discharge at a rate that can kill them in 3 to 4 months. They need a tender to maintain them, even if they are disconnected and have no draw on them from the vehicle's electrical system.

    The advantage of LiFePO4 batteries is that if there is no draw they will sit there happily for a year or more. If there is a draw, all batteries will need a tender. Use a proper tender though, not just a trickle charger.

    Few battery manufacturers give more than a 12 month warranty (motorcycle or car) ... coincidence .. ???

    Oxford "oximiser" is keeping my Motobatt alive. Cheaper than a new battery

    Oximiser has a quick connect cable that you attach to the battery terminals which has a waterproof cover. You slip it somewhere discrete on the bike and then no more taking off the seat (or whatever - it's even worse and much more tedious on my bike) to get to the battery.

    At my last place the bike was outside so I couldn't leave it plugged in all the time and I wasn't riding on a daily basis. Just put it on for half an hour before riding every week or two and it kept the battery going fine. Before that I was going through a battery in 8-10 months (Italian electrics).

    Neither I nor Mrs H have ever had to replace a motorcycle battery. That's 11 bikes and over 400,000km ridden in 12 years.

    Some write their bikes off ... before the battery needs replacing ...

    I just replaced the original battery in the Kizashi after 80k and 3,1/2 years with a new Repco one. It came with a 3 year warranty.

    Waiting for the bigger models with a greater reserve to come out. So much of modern cars is electric these days. One worked fine in the MX5 for 18mths until we sold it. Left the battery in it too. Another guy with a Subaru Forester had no problems with the 27A in his car either.

    Maybe because of the size, or possibly superior charge and control circuitry, but car batteries seem to last way longer. I have a 2003 JDM Honda Accord purchased about 5 years ago, which had some obscure brand Japanese battery. The car gets used maybe 2 -3 times a week, short trips mainly, yet that battery lasted till just recently.
    The KLR is onto its fourth battery since 2008. Hopefully the Oximiser will help this one last a bit longer.

    As already said, it's probably your irregular use that's shortening the life of the battery.

    It took about 9 years and a winter to finally kill the original CB919 battery, and that was about 120k, so not bad going at all. The BMW one I replaced after a couple of years as a preventative measure, as the OEM ones are known to work work work, not work, even mid trip. Couldn't afford to have that, so put a Shorai in since circa 2011. Modern bikes are now much like cars, voltage has to be in a small band, otherwise nada.

    Dad's 2001 Merc has a monster battery, and we believe it's still on the original... replacing it won't be cheap tho
