$100 · 2/20/80A Schumacher Nascar Advantage car battery charger

I have a Schumacher car battery charger for sale. It has a digital display which will show battery %, voltage, or alternator %. It will charge small batteries at 2A, regular car/truck batteries at 10-20A, and has an 80A engine start feature for boosting dead batteries. The charger works very well, but I've never used the engine start feature, so I have no idea how well that works. The newer version of this charger sells for $160+tax. https://www.princessauto.com/en/2-30-85a-fully-automatic-battery-charger-with-engine-start/product/PA0008773293
