Product Description

Amazon.com

The Schumacher SC-1200A/CA SpeedCharge is a fully automatic battery charger that uses advanced technology to charge up to twice as fast as conventional chargers. Automatically adjusts the amperage rate to charge and maintain batteries efficiently. The 50-amp clamps are compatible with both top and side-mounted battery posts. Its easy-to-read LED indicators show battery charge status at a glance. Quickly charge and maintain conventional automotive batteries, deep-cycle, AGM, and gel cell batteries.

Multi-stage, automatic charging for 6V and 12V batteries
Multiple Charging Modes

Automatically adjusts the amperage rate to quickly charge all types and sizes of batteries. The charger monitors battery condition and adjusts charge rate downward to prevent battery damage for car, truck, marine, RV, and farm equipment batteries. Also adjusts automatically to Slow Charge, a trickle setting for charging and maintaining small batteries, such as those for motorcycles, ATVs, snowmobiles and lawn tractors.

Sturdy, Built-In Handle

The built-in, retractable handle serves as convenient cord wrap for the 50-amp clamps and power cord, in addition to providing easy portability.

Microprocessor Controlled

Microprocessor Controlled Technology with multi-stage charging lets the Schumacher SC-1200A/CA deliver added precision, safety, and battery life. This technology lets you charge your motorcycle, car, or utility vehicle batteries up to 2x faster than using conventional chargers.

Fully Automatic Operation

The SC-1200A/CA automatically switches from Continuous Charge to Float-Mode Monitoring, which allows the charger to maintain the battery when fully charged. The SC-1200A/CA resumes continuous charging when the battery becomes discharged.

Cheap, very compact and easy to use.

So I bought another SC-1200 and realized that it is the best charger available for my needs.

It is listed as "Automatic" meaning will cut off when battery properly charged.

Verified Purchase
light weight and fool proof.

Some people complained it will not charge a totaly dead battery.
This is safety feature so it will not turn on if nothing is hooked up it.

To charge a dead battery - you have to give it a little pre charge to get it to about 1 volt so the charger knows something is actually hooked up to to it.

To do this:
1. unplug charger from wall
2. hook battery to charger
3. press and hold "display" and "type" button at the same time
4. while holding those buttons - plug the charger into wall.
* this will bypass safety features and charge the battery even if it is dead (assuming the battery can be charged at all)
- do not run in this mode for more then 5 minutes or you can damage unit and battery.
- this will get the battery enough of a charge so that the charger can detect a battery is hooked up to it (1 volt) .
5. unplug charger from wall.
6. wait 30 seconds and plug in charger into the wall. This will put it back into 'regular' mode and start charging your batter properly

Good luck!
Brad

Forgetting to remove the negative connector before storing my vehicle for the winter; the internal sytems and alarm drained the battery, and of course it was sulfated. This unit worked like a charm. The battery was down to 8 volts/15%. The SC-1200a properly began to charge, then desulfate, and slowly was able to get the battery back to 98% before I removed it to start the car. This took approximately 17 hours (700 CCA Battery), which isn't bad for a dead/sulfated battery using a charger costing less than $50. The plus is you can use it to maintain your battery on a vehicle you do not drive much. Keeping your battery charged above 98% can greatly extend the life. How long it will the charger last running 24/7? ...I do not know yet. I have only had it maintaining the battery for 3 weeks, but still no problems. It does have a cooling fan which probably should be cleaned/vacuumed occaisionally; and I've never felt the unit being hot to touch. Not sure what problem the first reveiwer had, or if the unit he had was defective or dropped before he purchased it. For a $50 charger which maintains and also desulfates a battery, you cannot beat it.

Put a new battery in a family member's vehicle.
Then the vehicle set idle in a family member's driveway for about 6 months.
(because they neglected to start and run the vehicle every week or two, the battery had fully drained)
Went to try and turn it over and nothing!
No dash lights, no dome lights, nothing.

I initially tried to charge this dead battery with an old style charger (one that weighs like 10 lbs+), a vector brand.
Set the charger to the 8amp charge setting.
After a hour or two there was no noticeable change in the battery.
When vehicle's battery cables were reconnected it still could not even begin to turn over the vehicle.

I had my doubts that something so lightweight like this schumacher 1200 could do better than an old school battery charger.
(I know that in theory, these newer tech chargers should be able to charge a battery more accurately and efficiently due to the
solid state circuitry they utilize vs the old style chargers).
So I went ahead and hooked up this Schumacher 1200 and toggled it through the various modes.

I finally set it to the desulfation mode. I heard the cooling fan kick on low and then high.
According to the digital display it was cycling between 12 to 16 volts. I let it run for about 3-4 hours.

I removed the schumacher 1200 and hooked up the vehicles battery cables again.

The vehicle easily turned over, just like someone had installed a new, charged battery into it.

This was rather impressive because the manual stated that the desulfation mode would toggle to the regular charge mode after desulfation was finished. Then when the battery was fully charged the charger's LED would go green.

Stay far, far, far, away from this charger. I walked away from tested, good, low charge battery being charged on the 8amp setting connected to a 750CCA regular car battery and when I came back a couple hours later it was boiling and still trying to charge! I checked the charge voltage and it was at 16 volts (measured with a Fluke meter)! Bad, very bad, charger and not automatic or smart at all.

I was hoping to find the Schumacher model 7000A 2/20 Amp charger to review, but this 1200A is just a variation on the same thing. Looks identical too. After reading bad reviews of Schumacher and Vector it's clear these companies can't do anything right. Seems any product that has a microprocessor is programmed by the incompetent. Let me tell you about Schumacher speed chargers.

They won't charge batteries that don't already have a significant charge. If your battery drops below 10 to 11 volts, forget it. You'd have to have a manual battery charger as backup for when this won't charge, which eliminates the need for this thing in the first place. The explanation from the company is that the charger has to feed off the voltage in the battery, blah, blah. The purpose of a battery charger is to charge batteries, period. Then I was lied to by the tech and told if I hold down a certain combination of buttons when plugging the unit in, it would go into manual 2A mode (where the processor doesn't decide it won't charge your battery), but I sat there on the phone with him doing just as he said, and turns out no such feature exists. The manual doesn't mention anything like that either.

The charger is totally unpredictable. It almost always goes into desulfate mode. It has never completed a charge after coming out of desulfate mode, but ends in an error. Needs to be unplugged and plugged back in to start charging again to "completion". However completion doesn't seem to get the battery to 100% power, more like 80%, if that. Sometimes it won't charge at 20A and drops down to 2A. Don't know why. And according to the manual, desulfate mode can take up to 10 hours. So much for speed charge. Need to get into your car and go somewhere?
