Great product. Definitly water proof as it got wet when rain storm came in as i was hooking it up to my 85 honda rebel and is still working fine. It came with a battery cable fuse ring and alligator clamps, 3yr warrenty info and great detail instruction on how it operates. Easy to read charging lights to know what stage your battery is at.

I had this charger hooked up to my tracotr when one of those one in every ten year storms passed through. It didn't miss a beat and my battery was at full charge the next day!

The tender does exactly what it is supposed to do...keep the battery charged. Simple and easy to use. My only suggestion would be to change the color of the charging light (amber) to something different. When the battery is charged, the light is green. In direct sunlight, the amber and green look alike.

Does this unit have protection so as not to overcharge?
Anthony H on Nov 3, 2014
Best Answer:Indeed it does! It will switch from a full charge to a "floating charge" mode so you can keep your battery at an optimal level. I have been out of state for the last six months and my FatBoy was plugged in the entire time. Came home, unplugged and she fired right up as anticipated. This is a GREAT lil' purchase!
