Have used Battery Tender brand tenders for years...they are great! I need to buy one specifically for my snowmobile and was thinking of getting an extra one for my streetrod as well. Generally, I swap the tender between the snowmobile & my SERK during the off-seasons.
So, today as I was ordering a new battery for the snowmobile, I was looking at the various tenders that are now available....
Check this out.....charges two seperate batteries at once and I like the looks! [smiley=xyxthumbs.gif] $139.95 & free shipping. 8-)

The BT-TWIN housing is a very close replica of the popular V-Twin motorcycle engine configuration. An internal sound chip mimics the sound of a motorcycle engine starting when you connect the charger to a battery. For your convenience, there is also a button to let you activate the sound at any time.
This charger has 2 separate 12 volt outputs with 800 millamps of pure constant current charging power. Coupled with a super smart brain (IC chip), the charger will constantly monitor, charge, and then maintain your battery.
