We have a large car shop charge probably 4-6 vehicles a day in winter. We've always bought the small Schumacher chargers till these. The new feature fully automatic with Microprocessor is junk. We have allot of cars with batteries we can save trickle charging over night or 24 hours. These new chargers used along side a 10 year old model wouldn't charge them shows battery bad, the old units would save the battery and be just fine.
I bought this a year ago and just got to use it. The wires melted and almost caused a fire. I wish I could get a refund. I want to buy a better one Adding to my remarks that it was only the 3rd time we used it. After only an hour the wires melted and tripped the breaker
I left this charger on a tractor I don't use that much and it boiled the battery dry! I tried to save the battery by pouring in distilled water but that didn't work. This battery cost me $220 to replace. Bottom line don't leave these chargers on for long periods of time.
The case was damage and the front panel was popped out. Took it off to straighten it and the inside was full of rust . Straighten the case and put it back together . It did not work I sent ti in and expect a full refund!!!!!! there was no dagage to the shipping box or it's box??????
