    No need if the battery is fully charged you shouldn't have a problem. I usualy run the bikes once a week anyway so no need for them.. Plus my dad put one on his warrior and it actually rined the battery.

    When you store a bike, is when you use them. Your Dad got a 'Tender' that didnt monitor the batterys charge. Some actually 'Float' until the battery needs a charge.

    Storing is a relative term. They are in my eyes stored in my garage, but I have to keep them above freezing due to no antifreeze and stuff like that!!
  5. I use the ACI (battery Tender) charger on the bike and as well on my Mazda 323GTX that only comes out for autocross, or lapping days. Otherwise, its sits with a tender all the time. I have Optima batteries, and upgraded my ZZR to a AGM battery from Big Crank. Specs.htm

    I purchased mine at for very little money. also carries the tenders. I have the 3 amp model.

    The specs are quite impressive and you can leave this tender on for years w/o any issues.

    Humm, its windy, yet warm and sunny!

    Ive been using 'Deltran', brand.
    I use them on the bikes as well as an old '90 RX-7 Mazda.
    One, on my R1100r BMW has kept the $100.00 dollar battery alive for 3 years.
    Id dont remember the rate of decay for a battery sitiing, not in use, but its amazing how fast they can loose a charge. With Fuel Injection needing a 'Good battery' to start, they have saved me money and grief.
  7. I've got a Battery Tender Jr. on mine. Was stupid easy to install, and is cheap insurance. Why NOT use one :)?

    I have the Jr. as well. Simple, easy insurance. I use it on the bikes, the 4-wheelers, the lawn mower.... I hard-wired my bike, and use the alligator clips for everything else..

    Just about anything with a 12v battery can benifit from a 'Tender'. Rv's, Boats, Jet Ski's....

  11. yup, I've had to replace my battery once, and that cost like $40. I'm not sure how much those tenderers cost, but unless you plan on storing it for an extended period of time I don't see it being too useful.
  12. apparently they are pretty necessary for my bike... from what ive heard and experienced...

    so yes, i have one and plug it in every other week or so
  13. I made one using an old 14volt cellphone charger. The only thing I bought was the clips I solder on the wires. I just plug it in once every 2 weeks for 8 hours and haven't had a problem yet. It only puts out 400 milli amps so overcharging isn't a problem. Some people put them on a timer to come on for an hour a day but I haven't got that ingenius yet.
  14. When y'all put the batteries on the tender, do you unhook all the wires from the negative terminal? A coworker of mine told me you can fry a battery if you don't hook the tender up correctly. Something about not wanting to complete the circuit. I'm no electrician, so I thought "safer to ask".

    Anyone know the 'right' way to hook up a tender?

    Thanks in advance.

    You can leave everything connected.
    Powerlet, a company that specializes in power ports for charging batterys on motorcycles
    makes a port for charging, so you dont have to raise or remove the seat.
    The battery stays connected.
    I have a BMW battery thats been in the bike for 5 years, and is maintained in the bike.
