Schumacher Electric Fully Automatic Battery Charger & Engine Starter - 6/12 Volt Car Battery Charger, 200 Amp Engine Start & 40 Amp Boost - Alternator Tester with Multi-Stage Charging SC1309

Works great, fast booster charge, very easy to use.

Good price and good power. Purchased the item to replace a 30+ year old Craftsman roll a round charger and so for it is performing up to expectations. Starting boost is very good. I also like the ability of showing your charging from your alternator.

Works great

I bought this a while ago to replace a smaller same brand of charger that I had bought but it went bad and then the replacement one went bad, so decided to try a larger unit. I charge both car batteries and also a battery bank for both my home and camper which is four 6 volt deep cycle batteries hooked together as one big 12 volt battery. It works good at charging both types but I wish it had heavier cables, it doesn't matter if it's just a car battery or the big battery bank the cables get hot while charging. It doesn't matter what battery it is or how much the battery needs to be charged the unit always starts charging at the 40 amp setting and stays there until the battery is charged.

My husband purchased this to use at the track when he is drag racing. There is no power available so he has to use the generator on his race trailer for power. This will not work unless plugged into an outlet in our garage or shop. This is a complete waste of money and we are sorry we bought it. We had a different brand and it worked for years. Disappointed

Very happy with the product not hard to understand Worked very well

Awesome battery charger, has nice and easy features to use. I like the fact that it's automatic just hook up and go.

Works perfectly!
