    LiIon batteries are a completely different kettle of fish. Make sure you read up on the proper care and maintenance of those things because if you treat them like a lead-acid battery, you will kill it in short order (and they are VERY expensive to replace).

    Of course, a lot of people mistakenly call a battery tender a "trickle charger" but I can't assume you meant anything but what you specifically stated. If you did have it on a battery tender, make sure you have a model that works with AGM batteries, as that is what is installed in the scooters at the factory.

    It was sure a lot simpler when everything came with flooded-cell batteries. Now you need a special charger for every kind of battery type out there.
    Thanks for that post. I didn't know there was a difference. I believe mine is a trickle charger, fortunately it's only on for a couple of days at a time. I usually ride at least once per week.

    As for the Shorai, I looked into them and it does state they need a specific charger. My buddy, who doesn't really ride anymore, "I'm going to sell my bike.." Says he has gone a year in between starting and his shorai cranks right up. Of course low temps rarely get below freezing here.

    Although I would normally recommend Odyssey, they apparently don't make one that'll fit our scooters. Damn shame because it works wonderfully in my K1200LT. For my TMAX I used a WestCo battery (because Odyssey didn't make one to fit that one either). It looks like WestCo does make one to fit our scooters too. I would recommend that one if you didn't want the OEM battery.

    Any lead acid battery will fail prematurely if not properly used and charged. Unlike deep cycle batteries and other types of batteries, lead acid batteries are not designed to be severely discharged or kept in a low state of charge, when this occurs battery sulfation occurs and deposits form on the lead plates that reduce performance and prevent proper recharging. This is why a battery that is being left without being used for a period of time or maybe used for only short trips needs to have a proper battery tender used that keeps the battery properly charged and topped off. Many times just idling a motor or short trips will not properly recharge a battery (in our scooters or a car/truck). Too many deep discharges and not properly recharging a battery will cause premature failure.

    At our auto shop we see many premature battery failures in cars driven by some of our elderly customers because their driving habits are the hardest and less ideal situations for a lead acid battery - they drive very infrequent, so their car sits for days without being driven (battery gets depleted from parasitic draws) and they make short trips only down the block or just across town (so battery never gets sufficiently recharged ever).

    The webpage listed below has some additional information on sulfation in lead acid batteries as well as some good general battery information:

    I replaced my battery with a generic RV Lithium battery from Amazon. Since it is so much smaller and lighter, it didn't fit perfectly, but it was pretty easy to make a snug fit with some styrofoam. I expect to get many more years from it than a replacement Pb battery and it has better CCA (300). No need for a trickle charger or battery tender since Li batteries are stable and do not lose charge like Pb batteries. Not much more expensive, either. I paid less than $100 delivered to my door in 2 days (gotta love Amazon). If you do stupidly leave the bike on and discharge it (as I did); takes less than an hour to recharge completely.
