2NOT real high quality
By PF Anonymous
Ive had this a couple of years and it really hasn't measured up. It can charge quickly but not fast, has no over charge protection, most of the parts are on the low end (ie wheels, handle, cables, clamps). It seems to be twice as large as it needs to be. But the 2 biggest issues with this is the poor performance of the 200-amp start and the cables literally melting every time you use it. I have used this 15 - 20 times over 2 years and the cables have ROTTED off. First the cable insulation would melt and smoke when I used the 40 or 200 amp settings, then, when I could see the wire I realized it was corroded and soon broke. Its obvious the cables were the cheapest they could get away with and thats just dangerous. It makes me question whats inside. I wouldn't mind all the trim being low end but when you cut corners with the core product thats just not safe.

4Not a good charger for deep cell batteries!
By Richard George Tatro
I have been trying to locate from a charger that would individually charge Trojan 105 Batteries used for Golf Carts. The description said the SE4020 would do this but when I tried to charge a six volt deep cell battery it did not do the job. The clamps are not heavy enough to clamp heavy duty batteries, nor are the wires. I believe the wires should be a heavier guage to prevent over heating. The only reason I gave it 4 stars is because of the reason specified above. Also I really think Schumacher should have used a more heavier metal in the construction of this charger. The edges of the charger on the bottom are very sharp and could cut you easily if you are not very careful. The wheels are also what you would find on a toy doll carriage, not a good quality battery charger. As for being a charger for all other types of batteries this charger would probably do the job it as designed. Just cheaply constructed!
