Review on 🔋 Schumacher Battery Charger & Engine Starter - Boost & Maintain - 100A/30A, 6V/12V - Tractors, Cars, Trucks by Ryan Vaughn

The first one I got wouldn't charge with any of the batteries I tried it on. I tried to get some replies from Schumacher support via email but they were very slow to respond. By the time they replied I had already arranged for a hassle free return to Revane. I bought the 2nd. I have charged 6 batteries with it so far. The reason I only gave it three stars is because it doesn't seem to drop from a 30 amp charge rate to trickle charge when the battery is fully charged as the battery voltage was up to 13.2 volts and is still up 30 amps was charged charging mode. But on the other hand it charges the batteries and I like the error messages which seems to work well. The automatic voltage selection seems to work, and the boot mode is useful, especially on hardware that has been tuned for a long time and needs a little help.
