RE: Requesting list wisdom re gel battery and Battery Tender Plus



I've been pretty happy with number 3.  It keeps me in the garage and out
of my wife's way.  I actually charge my batteries overnight about once a
month throughout the off-season.  I don't think I've ever had a battery
that lasted lees than five years using this method.

Another thing to consider is how the user wants to use the product. Some

scenarios are:

(1) Store your bike for the winter, and hope the battery is okay in the 
spring.
    (Project Manager's Saying: Hope is not an effective strategy for 
success)

(2) Put your winter-stored motorcycle on a battery charger, leave it
there
    all winter, and possibly boil down your battery over 4 months.

(3) Manually put a charger on your battery and turn it off when you
believe
    it is right. Some folks use timed schedules. Some folks use voltage-
    based schedules. Most require human intervention, and/or a SWAG
    (Also known as the Scientific Wild-Assed Guess).

(4) Put your battery on a Battery Tender over the winter. It requires no
    human intervention. It won't boil down the battery.

I'm happy with my Battery Tender, needless to say.
