Amazon.com Product Description
Schumacher's SEM-1562A low amperage charger is an ideal way to maintain a battery's charge for people who don't use their vehicle everyday, who go short distances, or who do lots of stop-and-go driving. It can also be used to charge small batteries for ATVs, motorcycles, snowmobiles, and lawn tractors, or even for batteries that have a long storage time. In cold climates, they're indispensable for keeping batteries warm overnight and ready for starting. 
The SEM-1562A charges both 6-volt and 12-volt batteries. | Features
The SEM-1562A maintains both 6-volt and 12-volt batteries, keeping them at full charge using float-mode monitoring. The unit will automatically switch from full-charge to float-mode monitoring when the battery is charged to prevent overcharging. Smart display LEDs indicate whether the unit is in charge, charging, or trouble modes. Versatile
The SEM-1562A is perfect for charging small batteries, maintaining small and large batteries kept in storage, and batteries for motorcycles, classic cars, TVs, and boats. It's small enough to fit under the hood of your car or truck. Safe and Effective
The unit has a quick disconnect harness for easy removal. Use the 50 amp clamps to connect to the battery or permanently attach the ring connectors--great for hard to reach motorcycle batteries. It also has a reverse hookup protection in case the clamps are accidentally connected to the wrong terminals. Warranty
Every Schumacher power source comes with a one-year limited warranty (90 days on battery).

 ''ya get what ya pay for'' August 20, 2010
Peter Juliani (U.S.A.)
This battery charger / maintainer lasted all of 8 days !! I'm an electrician by trade and am well versed in areas like this.The owner's manual says it has protection internal to the charger. It has a bad design flaw because the protection is an internal 10 amp fuse that is soldered on a printed circuit board.Once ya blow the fuse the charger is history. I guess the old adage ''ya get what ya pay for'' applies here. A circuit breaker external on an expensive unit is probably available.
 strong enough for any regular vehicle August 3, 2010

I like the fact that there are two choices for voltage, as one can use it on car or smaller batteries, like for a lawn mover/tracter. I give it five stars for the lead content in the cords. The instructions tell you to wash your hands after handling them. They must have a lot of lead in Asia! It does the job I got it for, which is keeping a stored vehicle's battery charged up. It is not made for charging a dead or really drained battery. I just plug it into the battery connector every couple of weeks, and let it charge for an evening. I guess one can leave it on all the time, as it stops charging automatically, but I don't feel comfortable with that, and I don't know if it uses electricity when it's idling.
Never leave a battery on cement or a wet surface because the power will drain from the battery quickly.
Works for me August 1, 2010

I work from home and very rarely drive...when I go out typically I take my wife's car or she drives. In fact, I failed to drive my truck for about 6 weeks and it wouldn't start (Battery was dead). Saw this on sale for 20 dollars on Amazon and picked it up - when it arrived I hooked it up and 4 days later was fully charged / battery worked great again. Key here is the 4 days - this really is a slow/trickle charge so don't expect it to be very speedy...there is a guide in the manual where it says how long things might take based on CCA value associated with the battery you have. It did the trick for me and so I'm happy with it.
Beware-- SEM-1562A does NOT have float mode! July 30, 2010

Beware-- the Schumacher SEM-1562A does NOT have a float mode and will NOT safely maintain stored batteries. The manufacturer has invented the phrase "float mode monitoring" to mislead buyers. To "float" a battery means to prevent it from discharging by applying a steady voltage at very low amperage. When a battery charger is in "float mode" the battery neither charges nor discharges, so it will last a long time because batteries age and wear out with each discharge-recharge cycle. The Schumacher SEM-1562A does NOT have a float mode. Instead, according to the documentation packaged with it, the SEM-1562A charges up any attached battery then turns off the charging voltage. The device then monitors the battery's own voltage until that falls significantly (indicating partial discharge), at which point the SEM-1562A re-charges the battery. That is to say, according to Schumacher, the SEM-1562A device CYCLES the battery. Instead of extending the battery's life, this process will SHORTEN THE LIFE OF THE BATTERY. Since true "float mode" chargers are most desirable and the SEM-1562A lacks float mode, Schumacher has evidently decided to mislead buyers by redefining the technical term "float" to mean "discharge" in the phrase "float [discharge] mode monitoring."
If you want a small charger with a proper float mode, consider the Battery Tender 021-0128 Battery Tender Plus 12V Battery Charger.

Inexpensive to buy, but this unit had a faulty cord that prevented the battery from charging. Called the manuf after playing wit it for two weeks and found out if you can't show a receipt of purchase they won't stand behind the warranty. You get what you pay for I guess
