Plug it and forget it. Attach it to the battery, plug it in and walk away. Love that it reads the draw and automatically adjust from charging to a trickle/maintenance charge. November 30, 2015
Very useful in emergencies too I use it in my garage to keep my battery charged. Also use it it when the battery is low to charge it up. Ine time I had the battery die on me, I got my car, hooked it up for 15 minutes and I was up and running. I love it. September 28, 2015
Works on everything Got it for my bike, used it on lawn mower and my daughter's four wheeler. September 21, 2015
works as requested Good product. They want 37 more characters so here they are lol August 17, 2015
does its job Very nice little product. To fully charge a dead battery I charge overnight. Great for battery storage as well. Would highly recommend. July 27, 2015
BT rocks! I have no idea why I listened to a parts dept person to sell me another brand of battery charger. Needless to say it did not charge my battery enough. I take my bike out to warm up when the winter weather permits. I barely got the bike turned over. Went straight to Revzilla and obtained the leader in battery chargers, Battery Tender. This is just my opinion, but I trust this source. Never again will I buy anything else. February 24, 2015
Excellent to keep my battery juiced up for the winter Small design but efficient. All cables you need. Good enough for a big twin and sport bikes. February 2, 2015
Simple to use and effective. I am not the most technically inclined but found this product very easy to use and it works just like it says it would. I have not charged a battery with it but like that I could if I needed to. January 21, 2015
