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.

Customer Reviews

Great maintainer
After having the battery on my "summer only" convertible go
flat last winter I decided to invest in a battery maintainer.
The Schumacher SEM-1652A was the best compromise of price (around
$40 with shipping), features (a normal charging rate, and a
lower maintaining rate, with overcharge protection and indicator
lights), and small size (fits easily under the hood by the
master cylinder, battery wiring adaptor with quick connect makes installation and removal a snap.
The changes I would make to it are few. I'd add a few extra
crimp-on terminals of various ring sizes to the kit, so different
power connections with the wiring adaptor could be made (my car
has the battery mounted in the front fender well, I had to get
larger ring terminals to go on the remote jump starting terminals
under the hood. The second is a matter of economy. Once the battery has reached 12.5 volts, there's no real reason to run
the charger/maintainer 24 hours a day. I hooked mine to a timer
and have it turn on for 3 to 4 hours every night (when the
electric rates are cheapest) to keep it charged up. While
it's true the circuitry in the charger will eventually drain the
battery if the unit is left connected when the unit is not
powered, the actual current flow is only a few milliamps per
hour, and charging 4 out of 24 hours has kept the battery at
12.5 volts for the last two months. With this in mind I'd add a
programmable timer circuit to the unit.

Great charger but better deal is waiting for you
This is a great charger but the same company (schumacher's battery maintainer), makes an identical product for sears, branded as diehard.
It costs the same as on amazon but comes with a 3 year warranty, not the standard 1 yr. warranty found here. Plus you don't have to deal with shipping hassles when you can just go to your local sears and pick one up or exchange if you have problems.

battery charger
Very good item for charging and maintaining batteries. Have used on my motorcycle and car batteries, as well as my lawn mower battery. Works well and actually tells you when the battery is fully charged, which is one of the best features of this charger
