Purchased it to replace a bench power supply that was about 30 years old that gave up the blue smoke. For the money this was a very good purchase, good value. Plus the prompt shipping through Prime. Other places have it but add shipping and such...

I got this as part of a mobile solar system I built. It works great just as described. The other reviewer didn't even hook it up. This is worth the money

This 20 amp controller is exactly what I needed for my Solar electric trike.
I previously purchased an MPPT 15 amp controller that would trip out daily during my ride to and from work (about 1.5 miles one way) That was my poor shotgun guessing skills. When I did the math and found I was drawing 18 amps I saw my problem.
So far the unit has tripped once due to an undervoltage, this was after putting about 10 miles on the bike and then climbing a hill.
I've had this controller for about 3 weeks and have had no other issues.

I bought this so I could expand my two panel system up to four panels. It appears to be working fine. The instructions were lacking but the diagrams on the unit give all the info needed. This unit does not have the auto on and timed shut off the 10 Amp units appear to.

This review is from: Schumacher SSC-1500A Ship 'n Shore SpeedCharge Charger with included battery clamps (Misc.)

As others have noted, the percent-charged reading can be grossly misleading. My experience is that when it shows 100%, you can expect to continue charging for another couple of hours before reaching full charge. Other than that, this charger works well. The biggest consideration with this product, however, is life expectancy. While this charger comes with a five year warranty, you are unlikely to get anywhere near that before it dies. This has been my experience with several Schumacher battery chargers. Unfortunately, there is almost nothing in the way of comparable items by other makers to choose from.

Tests, Charges, Maintains, Desulfisizes - Gel Cell, AGM, Deep Cycle and Starter Lead Acid, March 19, 2009

Kevin Foster "Master of none" -

This review is from: Schumacher SSC-1500A Ship 'n Shore SpeedCharge Charger with included battery clamps (Misc.)

As my title states, this charger handles all four main types of large batteries: Lead Acid Auto Starter batteries, Deep Cycle Marine, AGM and Gel Cell. You select battery type and size and it takes care of the rest. When you first hook up the clips to the battery and plug in the charger, selecting battery type, it tests the battery and gives you the volts available as well as the percentage that battery is currently charged! Many times I've wanted to know that. You then select battery size and it starts charging. If you select 15 or 10 amps, when the battery is fully charged it goes into a maintenance mode automatically! You can leave the charger running forever - and it won't over charge the battery. Also - if your battery is damaged by sulfide build up, it detects that and runs a cycle to clean the battery and give it life again if it can. Wow. I wonder how many batteries I've replaced that could have been revived or kept alive by this charger?! This is going to save me a lot of money.

I purchased a new 850 cc amp deep cycle battery to use as an emergency power source for my amateur radio equipment (I'm a net control storm spotter for the National Weather Service Skywarn network). This brand new battery tested at 95% charged - so I fully charged it (while using the radio) and it worked fine. Charged up to 100% and went into maintenance mode automatically. Took the charger to the farm and connected it to a dead tractor battery. Showed 11% charged and began building the charge immediately. Was up to 15% in about 7 minutes when I had to leave. I'll have to update this review later to let you know if it was able to salvage that poor battery.

I know of no other chargers that test the battery, charge all types of batteries and can safely be left on to maintain them as well. Go check out the cost of Gel Cell battery chargers - and you'll find this is a deal.

BTW, if you forget to turn it from 'test' to 'charge', after 10 minutes or so this charger will automatically charge up the battery and keep it maintained for you! How easy is that?

There was a good week delay before this vendor shipped. The product is very straightforward to hook up, and has reversed polarity protection. The green lights on the unit were indicating my battery was fully charged, yet it was only at 12.2 V (not fully charged at all). As one other person indicated, the low-voltage cut off is fairly low, and your battery would be severely depleted before disconnecting. Having a higher voltage cut off would be much better for the battery. This is basically an entry-level controller, so I figured I'd got about what I paid for. I would certainly not choose as controller for a large array, but for one or 2 panels it should perform adequately. I have yet to check the higher voltage cut off, but is it supposed to kick off at 13.1 V. The maximum input voltage is supposed to be about 14.4 V, and have not seen readings higher than this. There seems to be a lot of "noise" on input voltage, but it gets the job done nevertheless. Again, about worth what I paid for it. This is certainly not a high-end product, but does perform adequately for the price.

For the past few years I used the SunForce 7A charge controller and it worked very well. When I added another panel to my small system I upgraded to this model to handle the extra few amps.

This charger is really a step above the SunForce model in the same price range. It is not simply an "on/off" solid state switch... it controls/limits the current to the batteries to maintain a very precise voltage. When the batteries have been fully charged, it then float-charges at a constant rate. This will keep the batteries much healthier over time than simply cycling between 13.1V and 14.2V. If you are using SLA or Gel-SLA batteries, I think you'll really find this charger is made for these types of batteries.

I like the output load control. A simple push-button on the front of the unit turns the load on/off, and the small "digital LED display" is just a red LED indicating if the load is on. It doesn't give any sort of digital readout like the details above say, however it's not necessary if you have your voltmeter handy.

The LED indicators are sufficient, telling you if the solar system is providing power, the battery condition, and the load state. The wiring terminals seem sturdy and can handle 10-gauge wire which is nice. As others have said, the manual is sort of a joke. It gives you the bare basics but since this is a pretty simple device you don't need a book to figure it out.

Really pretty happy with this unit. I was considering the SunForce 30A charger which is over 2x the price of this unit, but glad I tried this one first.

Perfect pocket multimeter, May 12, 2006

Luke Anderson (Cape May, NJ) -

As someone who only occasionally needs the services that a multimeter can provide, this is the perfect device. It's small, easy to store, accurate, and durable.

The unit I received looks much better than the one in the picture. It has a yellow plastic construction, comes with the black/red probes, and includes a 9V battery.

And although it is lightweight, it doesn't seem fragile at all. In fact, it seems very durable.

The instructions are marginally useful at best, but that's not really important since it performs to my expectations. And the price can't be beat. Definitely a handy device to have around the house.
