Anyone can use this easily
Darn, my riding mower wouldn't start last week, just as the grass was ready for the year's first mow. I am a single 47 year old woman who knows zilch about machinery. Since the mower wasn't making a peep when I turned the key, I went with "battery is dead". Every month over the winter I started the mower up and ran it for 5 minutes, but guess this last April freeze finally zapped it. I researched chargers and this one sounded the best for the money. Paid for it on 4/10, used supersaver shipping and got it on 4/13! My Troy-Bilt manual says to use a 12-volt charger on 6 amps for one hour. The Schumacher manual says to use this on 2 amps for 3-8 hours for riding mowers, but I went ahead and set it for 6 amps. When I plugged it in, the ammeter (never heard of that word before, but the manual told me the meter was called that) read 3 amps, which supposedly meant the battery was fully charged. Doh!!! But I went ahead and charged it for 1 hour and, Eureka, the mower started up just fine. This charger is so easy to use. I ran an extension cord out to my shed, clipped the red clip to the positive terminal, the black clip to the unpainted rear end of tractor, put the power plug in the extension cord and waited one hour. Can't beat that for simplicity. (I finally noticed I could flip the mower seat up out of the way of the top of the battery - that's how much of a novice I am.)

Just what I wanted
I reviewed another charger which I bought at Lowe's and ended up throwing away. It was an automatic charger, the only problem with that type of charger is it will charge a battery that is completely dead. A manual charger is what I wanted, and this is perfect for the average "shade tree mechanic". It will not jump start a car you have to leave it on for a while, but it works very well.

Read Before Use!!! Potentially Dangerous Wiring Issue
Received this from Amazon and put it right to work attempting to revive a battery that went dead over the winter. As I waited for the battery to charge, I noticed the sealed battery had vented itself through its safety valve several times. The battery also became quite hot, more than what was expected. Almost hot enough to be uncomfortable to hold. Upon checking the battery with a multimeter, the multimeter displayed a negative voltage. I spent the next hour double checking everything, trying different batteries, etc. Still showed negative voltage while charging. I decided to inspect the unit (4x torx 15 security screws) and lo and behold, the clamp wires were incorrectly connected INSIDE THE UNIT. It is clearly marked "(-) out" and "(+) out" on the board inside. It seemed to me when I unboxed the unit, that it may have been opened before. However, after reading some of the 1-star reviews here, I am beginning to think it really is a case of extremely poor quality control. This issue would explain a majority of the problems many others have given about shorting out, killing batteries, etc. I'm surprised there isn't a recall on this item. I would never think I would need to check a new item to make sure it was assembled correctly, given other older Schumacher products I own. The unit seems to work correctly after swapping the blade connectors to the proper locations. Time will tell if the battery is destroyed and if the unit lasts much longer.

Money Saver
I had one of these over 30 years ago that I bought at a yard sale as a teen. When I joined the service, I left it behind for my dad to use. Now being a geek, I've got two "Smart", computerized battery chargers. Fully automatic, they do everything but hook themselves up. The one thing they won't do is to charge a totally flat battery. Instead, they insist (via codes F01 or F03) that the battery is bad and that I need to replace it. Just as I was about to pull the trigger and order a new battery for my Goldwing motorcycle (at $100+ on sale), I remember this type of "dumb" charger, popped over here to Amazon, found and ordered this one. Using my Amazon prime, it was here LESS than two days later via UPS. I took it home, hooked it up on the 2A charge rate. Four hours later I took it off charge as I wanted to go to bed. You can't leave these running all night or they'll kill your battery by overcharging it. Then I hooked one of the "Smart" chargers back up. The "bad" battery now had an 85% charge. I left the smart charger on to top it off until morning. It's been a week now and the "bad" battery starts my Wing every morning. Therefore, spending a little over $30 on this battery saved me over $70 just by not having to replace this one battery. p.s. Next up, I want one of those Shumacher 200A roll around units that will jump start/charge anything. LOL

Very good, time tested unit
Very good, time tested unit. Has a auto re-setting circuit breaker in the event of a short circuit. One caution, if you want to use this on smaller 6 volt batteries, such as an antique motorcycle battery, as I did, the 6 volt charging rate starts out at 6 amps, which may be too much for that type of battery. The charge rate does taper off to approx. 2 amps. It doesn't automatically shut off when the battery is fully charged like a battery tender does. I've used it on my tall 6 volt Harley battery but it requires close monitoring that the battery doesn't over heat or boil itself dry.

Not good for electrolysis
It worked alright for electrolysis for a while, but then it flashed/popped and quit working after about two weeks. Wasted my money on this one. If you want to use for electrolysis, I would look elsewhere.

Whilst advertised on Amazon.co.uk and mentioning free UK delivery, this is an American market model for 120 not 240 V!! I just went to charge my battery and found out. I also incurred a customs charge with the delivery. If you're in the UK steer clear and get a fit for purpose model for someone who is advertising the right product ion the right market. £80 wasted (costs plus customs) and still a dead car, not happy at all.
