    Bike Bandit has just published an article detailing the advantages and disadvantages of lithium batteries and also compares them with the lead-acid type: http://www.bikebandit.com/blog/post...m-iron-batteries-really-better-than-lead-acid

    I just replaced my Scorpion lithium battery, which had been in service on my 2009 F650GS for the past 5 years. I was finding that I had to charge the battery at least once a week to keep it happy, so I decided that it was time to replace it, which I did with a Bike Master TruGel battery that seemed to provide very good service in my daughter's occasionally-ridden R65LS. Plus, it was about half as expensive as a replacement LiFePO4 battery - although it sure is a lot heavier.

    This weekend I gave the old lithium battery to my commercial radio equipment engineer friend and he gave it a full rectal examination on some battery equipment testing equipment that he has in his shop. He ran the battery down to 8 volts and here are his results: The battery has a capacity of 3.681 AH. That's about what I expected. Cold Cranking amps about 300, reserve capacity, about 40 seconds. Time for a new one.
    Attached is the battery testing chart that he sent me for this battery.

    Lithium batteries sounded really good initially. But they don't seem to provide enough bang for the buck IMHO.

    And as far as the weight savings goes, (a) I'm not racing my GT, and (b) I really need to lose a few pounds myself.

    But Richard, the new capacity was not much better than 3.8AH. LiFePO4's typically have 25% of the capacity of Pb-acid they are said to replace. Very low internal resistance allows high current cold starting power but the low energy content means it had better start quickly else the battery will be drained.

    Li batteries also don't like to be installed in motorcycle models that have electronics (like the date and service reminder ) which are keeping warm while the bike is off. If you use one like I did, be sure to hook up a maintenance charger to the bike and use it at least once a week. Still, I got my money's worth out of that battery. It lasted 5 years and cost only $80 during a half-price sale at batterystuff.com and never left me stranded - which is more that I can say for the stock BMW-brand Exide battery that only lasted 6 months.

    Hello,

    Batteries are a very special topic.

    Druing the last years I tried different batteries.

    It is very difficult to say which battery is the best´, because it depends on how you treat your battery.

    I use the Optimate 4 charger for battery care.

    Currently I am using an GEL battery "LICENCE".

    I ordered both parts from motorcycleparts Hornig.

    Until now I had no Problems and I really an rely on this battery.

    Here is another article by the on-line accessory store Bike Bandit regarding 12V motorcycle lithium batteries that I found interesting and it didn't seem to contain too much BS. Just keep in mind the source. The video is kind of entertaining, too: http://www.bikebandit.com/blog/post/...-buyers-guide5

    Here is another Bike Bandit battery article. This one discusses "cold cranking amps" and why they are not all that important as a measurement of motorcycle battery performance: http://www.bikebandit.com/blog/post/...s-on-a-battery

    If I was looking for a new battery, I'd look at one of the off-brands like William did. User reviews will tell you if the battery is worth buying, or not.
