    <p>Prior comment...mentioned the Optima battery... Odesseys are my
      pref. AGMs are the only way to go when not used
      regularly/seasonally.<br>
      Yes, they are more expensive. I've had one running for over 11
      years now. THAT particular battery has also seen at least three
      totla discharges to where the starter wouldn't even click, and it
      still holds a charge to this day.<br>
    </p>
    <p>Lead acid (wet plate) batteries have a self discharge rate NOT
      designed for non-repetitive regular use. AGMs are closer to
      'storage' batteries with a much higher current destiny and MUCH
      lower self discharge rate.<br>
      anyway.... to the point.....  if you fully charge an AGM battery,
      and disconnect it from the car electronics. You should be able to
      go a year or two without starting or charging and the car will
      start without issue.<br>
      BTDT for years now.  One of my cars hadn't been started (let alone
      uncovered) for nearly 3 years.  The Odessey battery (a 925 size)
      was still sitting at 12.4V and the car started without issue.</p>
    <p>Ditto on the float charger comments.  BUT.... They CAN be left on
      but NOT when you have the rest of the car still connected.  The
      Juniors are trash. They see that 'trickle load' of the car, as a
      need to charge the battery.<br>
      Get a full tender or better yet a newer style digitally controlled
      tender. <br>

          For what it’s worth, here is an opinion from to experts I was
          surprised to hear.  One is a Porsche mechanic who’s been in
          the business for 30+ years.  The Interstate battery had died
          and even pumped out some white power at the end, out a
          breather tube from the battery.  I cleaned it all up well,
          worried about battery acid in the front truck.  I went to the
          shop, he’s an Interstate distributor as well, and bought a new
          battery and told him what happened, and that I’d had the
          battery connected to a Battery Tender Jr.  He told me that
          even that brand, which is good, is really not good to leave on
          all the time, and it will cook the battery.  He recommends
          putting it on for a week or two, then disconnecting for a week
          or two, and repeat.  Well that’s a pain.
          <div class=""><br class="">
          </div>
          <div class="">Then in my Airstream trailer which has two 12
            volt deep cycle batteries, I’ve read that the power
            converter that comes with the trailer also isn’t designed to
            leave plugged in all the time and it will cook the
            batteries, which did happen.  I tried using a Battery Tender
            Jr on that but it couldn’t deal with 2 batteries.  I was
            then told about an upgrade for the Airsteam power converter
            on Amazon, about $200 or so, which I installed and it does
            manage the float and it can be left plugged in for months
            and months no problem.</div>
          <div class=""><br class="">
          </div>
          <div class="">So be careful with Battery Tenders.  I have two
            Battery Tender Jrs and four Die Hard battery tenders for
            multiple cars, Kubota tractor and a boat.  Just be careful
            how long you leave them plugged in and check the water level
            if it’s not a gel battery.  I have an Optima in my Triumph
            and Kubota.</div>
