I first learned about the Schumacher SEM-1562A when I was using the Schumacher SC-1000A battery charger (which I also own) to put a “trickle-charge” on my Volkswagen Jetta TDI (diesel engine) battery during the cold winter months of Colorado.

It was getting pretty cold during the nights (around 20 below) and wasn’t getting much warmer even during the day.  I was using a strong anti-gel additive in my diesel tank, but my car was still pretty hard to start on those cold winter mornings.  There were a few times when I didn’t think that battery was going to have enough “juice” to get me started.

“Best customer service anywhere! I purchased a Schumacher battery companion in 2007. In July 2008, I noticed the amber light was on and the water was boiling in my motorcycle battery. The battery was approximately one year old and I was not sure whether the battery was unable to fully charge or the float mode on the charger was not cycling. I fond the Schumacher customer service toll-free number on their home page, called them, spoke with Jonathon, explained the situation, asked his opinion and he stated that it would be best not to take a chance. Although he had never seen a problem like this in their product, he requested that I return the unit to Schumacher, attention Jonathon, and he would replace it with a new one…

Then it happened.  It was the first weekend of subzero temperatures and I didn’t drive my car all weekend.  I went out on Monday morning and I couldn’t get it started.  In fact, I ran the battery completely out and it reset the trip odometer.  Crap!

That’s when I started using the SC-1000A overnight and especially on weekends.  I used it on the lowest setting, and it worked well.

My SC-1000A was working like a dream – and I still wouldn’t trade it for the world – but, I was looking for something a little more compact that was strictly designed to be left on a battery for the long term.  Plus, since my car seemed to need CONSTANT attention from my SC-1000A, it tied up the only battery charger I had.

So, I went shopping for another Schumacher battery charger.  However, this time, I wanted one that was less expensive, with fewer features, but was still well-built and completely automatic.  That’s when I found the Schumacher SEM-1562A.

“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, features, and size…

With a 1.5 amp trickle charge, the Schumacher SEM-1562A is designed to either charge a small battery, charge a large battery very slowly, or keep a battery charged up at all times.  The latter reason is why I bought this particular Schumacher battery charger.

When the battery is fully charged, the Schumacher SEM-1562A goes into “float mode”, which is a maintenance mode.  There are LED lights that tell you whether the battery is already fully charged or still in the charging process.

What I like MOST about the Schumacher SEM-1562A is it’s size.  It is small enough that was able to permanently mount the unit under the hood and connect the charger with the OEM supplied ring connectors.  Now, when I need to charge the battery (or just keep it charged during those cold winter months), all I have to do is connect to a power outlet with an extension cable and then plug in the quick-connect harness to send that steady 1.5 amp charge to the ring connectors that are permanently attached to the battery terminals.

“I needed a motorcycle battery charger/maintainer to keep the battery charged while my bike was dormant over the cold winter months. When researching suitable charger/maintainers I found there is a plethora of brands and models available, at wide price ranges. The brands with the highest reputations and reasonable prices seemed to be Schumacher and Battery Tender brands…

I liked the Schumacher SEM-1562A so much, that I eventually bought one of these for a good friend of mine who rides owns and rides a 1984 Honda Nighthawk motorcycle.  As most motorcycle riders do, she goes for long periods without riding (such as in the winter, or on extremely windy or rainy days).  Since she only rides her bike when the weather is perfect, the SEM-1562 is perfect for her.  She never has to turn down a spontaneous trip through the mountains because of a dead battery.

The Schumacher SEM-1562A typically sells for about $60, but can be purchased through online retailers for around $20 to $25.

    Brad. I have an older model Shumacher battery charger that was made for Sears. The control board has a burned out resistor on it. Else the rest of the circuits are in good shape. I’m trying to locate a diagram of the control board to determine the specs of the resistor. I’ve had this charger for several years and hate to throw it away. I’ve worked in electronics as a hobby and J-O-B nearly my whole life so am confident I can put this charger back in service with a little help with the control board. Thanx. Dale P. Appleton

      Dale, I am afraid I cannot help you. I have searched for a “service manual” for this unit, and have yet to find one. Unless the resistors have the multi-colored identification bands, I do not know of any other means of determining the specs on this resistor. I’m sorry I cannot help.

    I have SEM 1562A hooked to a deep cycle marine battery used on a driveway gate. It keeps going into the ‘abort’ mode (yellow light flashing). Have to unplug and plug back in to re set. Any idea why it aborts?

    • admin says:

      Have you tested the battery to make sure it’s still good? How old is it? Something you may also need to think about: deep cycle batteries need to be desulfated often, as they are very prone to sulfation. You may wan to check that out too.

    I have a SEM 1526a charger/ maintainer. I use it mainly for my motorcycle, but occasionally use it for my truck as well. Unfortunately I lost the quick connect that has the alligator jaws. Is there ANY way I can order a new set?
