easy to use This battery tender is simple to use and reliable . Safe and electrical cords are very long to reach to wall outlets. Perfect for expensive battery tender good product. March 22, 2016
Great battery tender Overall great product. Keeps the battery up to spec over long winters. Plus the included pigtails allow for a one time connection to the battery so it is easy to plug in without taking half the bike apart. March 15, 2016
It Works I have a 2014 HD Breakout FXSB and after my bike had sat in the garage all winter I had a bike that would not start. I bought this and it hooked directly to this attachment under my seat which made it so I didn't need the two attachments that this tender comes with; after about 8 hours I was able to start my bike, very pleased.

Takes care of all your battery storage needs. The Battery Tender simply takes care of all your battery storage needs. Clip on the gator clips, or permanently install for more regular use with included alternate post mounts, and plug it in. It is that simple. The light on the battery tender will start off red, then change to green when you battery is fully charged. After that, it will cycle on and off as necessary throughout the storage period (all winter for me). The Battery Tender has a multi-year warranty, unlike the knockoffs. That gives me confidence and security that this product will take care of my bike for many winters to come. Patrick March 1, 2016
Great value Must have for those who have a bike that might sit for a bit between uses, or when you've got a battery taxing v-twin. I never used a tender on my first bike which I would leave sitting and start a couple times through the winter, which can kill battery health/life. After a quick wiring of the harness I now know it'll be good to go next time I go to fire up the bike. February 7, 2016
Works as advertised. I finally got to use this now that winter is here. Works great, best price I could find. February 2, 2016
Good Buy from a trusted brand Revzilla carries quality products. This battery tender unit comes with everything you need to keep your motorcycle battery charged. I hung the adapter on the wall next to my bike and even with jackets in front of it, etc, it never overheated and cutoff automatically once the battery was charged. No issues, does the job, and importantly, great price! January 26, 2016
A Must-Have for Long Term Storage You can't go wrong with the original Battery Tender Junior. The device is easy to use and is plug-n-play ready. It's worked great and never gets warm or malfunctions. I highly recommend it! January 25, 2016
