First introduced in 2006, the International Battery Tender® BT-TWIN 800 continues the Deltran tradition for design innovation, advanced technology, and above all, cost-effective battery charging solutions.  

The BT-TWIN 800 is sure to be accepted as yet another solid new addition to the Battery Tender® family of charger products. This dual output, 12 volt 800 mA battery charger has all the charge characteristics of its cousins, the Battery Tender Junior and the Waterproof 800. In fact, it incorporates the same highly efficient surface mount technology electronic components that are used in the Waterproof 800. 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 brain (IC chip), the charger will constantly monitor, charge, and then maintain your battery. Although we do not recommend operating this charger in extreme environmental conditions it will charge batteries sized for ATV's, watercraft, motorcycles, boats, or just about any type of motor-sport vehicle. This unit will work anywhere in the world with an international universal input range of 100-240 AC Volts at 50/60 Hz.
