Review on Battery Tender 3 Amp Car Battery Charger: Automotive Charger and Maintainer for Cars, SUVs, and Trucks - 6V/12V, 3 Amp Charger by Aavon Dark

My wife and I are older and don't travel much. I am tired of my wife having to use her car only to find her battery is dead and expect me to rectify the situation immediately. She never left the car 2-3 times a week to charge the battery. When I got this charger and taught her how to unplug it before getting out of the car and plug it back in when she gets back, I was able to live my life with relative peace. I also have a smaller one that I've been using for 12 or 13 years to charge my lawnmower battery in the winter and it hasn't let me down yet. Highly recommended!
