SC1339 Battery Charger

Purchased Nov 2018, used to charge an AGM 12 volt battery, worked as per instructions, with the battery isolated from the car, which was inside a garage. I have yet to test with the battery still connected to the car and with the car being outside in cold temperatures. The unit makes absolutely no humming sound and does not even get warm, let alone hot. Will post another review after using outside and with the battery still connected to the car.

Works great, very dependable!!

I bought this charger to charge a battery for a 67 Chevy truck battery. It completely charged the battery and made it very easy to start up the truck the first time. I currently have the battery on trickle charge and it completely holds the charge. Great product!
