Schumacher SE-3000 Manual Fleet Battery Charger

I needed a charger for a large set of deep cycle batteries, something that would put out lots of amps continuously. And of course I didn't want to spend a lot of money. This charger has worked great, met all my expectations.

But understand what it is, a big heavy manual charger. Left on it's highest setting it will fry all but the biggest batteries. But if you have big batteries, 600 amp hours or bigger, it's great. That's amp hours, not CCA or cold cranking amps.

Why only 4 out of 5 stars? Two flaws. Two of the sheet metal screws on the outside are stripped, easy to fix. The other flaw is worse. The cables are only 6 gauge. If you use the charger at full potential, outputting 60-80 amps, for more than 30 minutes the cables get hot. Once the cables started smoking, melting the insulation, luckily I noticed and turned off the charger. This thing should have a least 4 gauge cables.

But I think most people will use it on car batteries, so the hot cable issue shouldn't be a problem.

The battery charger works wonderfully and it contains the desired features, but the sheet metal box isn't very sturdy. Like other chargers I've seen at various stores, the manufacturer saved a few pennies by using a light gauge sheet metal. The first item delivered was dented even though the shipping box didn't appear to have any damage. The return and exchange was quite easy. I still had the first one when the replacement item arrived several days later. The second item was also damaged. Luckly, I could assemble one good item out of the two I received.

Ordered two of these for local fire dept. they have trucks with 6 volt all the way up to 24 volt starting systems and one charger is easier to keep track of than four different voltage ones. A couple things i recommend after using this charger are: keeping an eye on the clamps they get hot on high charging rate with high CCA battery, and on 6 volt low it is not a trickle charger, so don't leave timer on to long. All that said it is a good value for a small fleet or farm in a big charger.

Charger is functional in 6, 12, and 24 volts. Will do lite duty charging. The cables are very lite duty, so be careful if you are charging high amps in 12 volts or using 24 volts. The case is very lite duty also, even though it was packaged well, it was dented but did not affect use. I kept it as it was minor and I figured it would eventually get bumps and scrapes during use. In my opinion not a "fleet" quality charger. I will get by as I am using it as a backup second charger. Bottom line: You get what you pay for. It was about half price of a "fleet" quality charger.
