Query: Good Battery Tender for the Best Price!

I was looking especially for a Deltran and found this one on Amazon.com for a substantial amount less than from the Deltran Company it-self. Plus with the free shipping It was definitely a bargain. I will find out if the tender has kept my two tractor batteries and my car battery from freezing after a long winter...when I return in the summer.I only needed a three tender but having the extra one never hurts. It's there if I need it. I have always like Deltran. Sorry I can't tell you at this time the tender did a great job...I'm just preparing for the winter while I'm in warmer weather.
